Installation

The schematic diagram is for reference only. Check the water inlet/outlet label on the heat pump while plumbing the unit.
Upon receiving the unit, check the packaging for any obvious signs of damage. Inform EvoHeat immediately if there is any evidence of rough handling. When the heater has been removed from the packaging check the refrigerant gauge on the front panel of the unit. When all refrigeration systems are operating, check the gauges are showing a pressure between the 10 o’clock & 2 o’clock range on the outside red band – any less than this figure means there may be a leak in the refrigerant system, and you should immediately contact your EvoHeat Dealer.
IMPORTANT: EvoHeat heat pumps MUST be connected by a licensed electrician. Under no circumstances should an unlicensed person attempt to install or repair an EvoHeat heat pump themselves. Heater electrical installation undertaken by an unlicensed installer will void the warranty. Correct installation is required to ensure safe and efficient operation of your pool heater.
Before installation it is very important to ensure 5 variables are carefully checked to allow the unit to operate correctly.

• Heater Condition
• Adequate water flow & plumbing
• Location
• Clearances & Airflow
• Correct electrical connection & supply

Rubber Feet
All EvoHeat units are provided with rubber feet which EvoHeat highly recommend being installed. The rubber feet help reduce vibration of the unit and help provide a space below the heat pump to install the drainage barbs.

Location of Installation
Evo recommend the heat pump should be installed in an outdoor location with appropriate ventilation. Installing the heater indoors without adequate ventilation, or in a poorly ventilated enclosed space, will result in very poor performance and can, in extreme cases, damage the heater. If a suitable outdoor location is unavailable please contact EvoHeat for specialist technical advice.

The Evo unit should be installed:

• At least 3.5m away from the water’s edge.
• No greater than 7.5m from the water’s edge (to avoid heat loss from the piping).
• No greater than 5m below the water level of the pool/spa.
• On a flat level surface.

Make sure the heat pump is not located where large amounts of water may run- off from a roof into the unit. Sharp sloping roofs without gutters will allow excessive amounts of rain water mixed with debris from the roof to be forced through the unit. A water deflector may be needed to protect the heat pump.
A rough estimate of heat loss over a 30m pipe run can be as high as 600 Watts per hour per 5 degrees of temperature difference between the air/ground and the pool water. These losses need to be taken into account over long distances and piping may need to be insulated to reduce heat leakage. If these installation guidelines cannot be adhered to, contact EvoHeat for specialist technical advice.
The casing of this unit is made from high quality durable stainless steel, however if it is intended to be installed in a coastal or corrosive saltwater environment; regular application of an anticorrosive surface protectant to all exposed metals and fixings is recommended.

Airflow Clearances
The heat pump unit needs continuous fresh air whilst running. The heater draws up to 47000 m3/h ambient air through the sides and discharges through the top fan cowl.
Ensure the heater is installed in a well-ventilated area with plenty of fresh air, a minimum gap between walls/fences etc of 1000mm on the sides and 3500mm overhead clearance. Leave sufficient space for unobstructed airflow into and out of the heater. Do not locate the heater in an enclosed area, or the discharged cold air will recirculate into the unit and consequently lower the heating efficiency as well as possible icing up.
When units of a similar height are placed side by side, EvoHeat recommend a 1500mm clearance between units.
*Fan discharge distance can be reduced by adding a Plenum to alter the air flow direction. Contact EvoHeat or a HVAC specialist for further advice. If you do not have a location with these suggested clearances, please contact our EvoHeat Tech Support Specialist to discuss appropriate installation locations.

Adequate Water Flow
All EVOHEAT heat pumps have a factory preset internal water flow switch. If there is insufficient water flow the heater will not operate.
It is CRITICAL that there is sufficient water flow to the unit. Incorrect water flow can cause a loss of heating capacity and efficiency and possibly damage the unit. Optimal water flow rates are listed in the EvoHeat manual. It is imperative that water flow is kept as close as possible to these flow rates.
Before connecting the heater to the plumbing, all piping must be thoroughly flushed to ensure no debris can enter the heater. Failure to remove pipe debris can jam or damage the flow switch and may cause damage to the heater. When cleaning the pool it is advisable to turn off your heater as restricted water flow may cause the heater to shut down and indicate low water flow fault (E03 error) or high pressure fault (E01 Error).
IMPORTANT: Size an appropriate water pump to supply water to the heat pump/s to meet or slightly exceed heat pump model/s design flow rate specifications. A by-pass must be fitted for each individual heat pump to regulate the volume of water flow through each heat pump. The by-pass is used to reduce flow rate to design flow rate specifications. You’ll know when design flow rate is achieved when there is a 2°C difference between Inlet and Outlet temperatures. This can be observed using each heat pumps digital display controller.

Drainage & Condensation
During operation, water in the air condenses on the fins of the evaporator. In high humidity, the condensate may be several litres per hour, giving the impression that the unit is leaking. This process is a normal function of heat pumps.
The heater will automatically activate reverse cycle or de-icing mode when required which also increases condensate discharge. This normally occurs at temperatures below 8°C. The condensate water will discharge through the base of the heater. As an option a pipe can be connected to the drain on the base of the unit to direct condensate water to an appropriate location.
Ensure the CS-i series units are installed level to evenly distribute condensate into and through the condensate trays. A quick way to verify that the water is condensation is to shut off the unit and keep the pool pump running. If the water stops running out of the basepan, it is condensation. AN EVEN QUICKER WAY IS to TEST THE DRAIN WATER FOR CHLORINE – if the is no chlorine present, then it’s condensation.

NOTE
Removal of condensation can be achieved via installation of a condensate pan or by plumbing to a waste water drain. If plumbing, EvoHeat recommend raising the heat pump of the ground approximately 100mm to allow enough space to connect the condensate lines under the heat pump together, then drain to a wastewater drain.
The condensate water captured will discharge from the heat pump through one end, typically where the heat pumps Inlet/Outlet connections are located. The condensate discharges from the heat pump through a 32mm female threaded connections. Ensure condensate is plumbed away from the heat pump to an appropriate location, ideally a drain.
Note: A 32mm Male threaded adapter is NOT supplied with the heat pump.

Plumbing
A by-pass must be created to regulate the volume of water flowing through the heat pump to achieve design flow rate, and to have the ability to bypass ALL water from entering the heat pump.

Flow Rate
Since there is no residual heat or flame temperatures the unit does not need copper heat sink piping. PVC pipe can be run straight into the unit.

Location
Connect the unit in the pool pump discharge (return) line downstream of all filter and pool pumps, and upstream of any chlorinators, ozonators or chemical pumps.
The CS-i 65 comes supplied with barrel unions for the Inlet/Outlet connections which accepts 50mm PVC pipe. The CS-i 130 & CS-I 250 have 100mm PVC flange connections for the Inlet/Outlet connections.
Give serious consideration to adding a quick coupler fitting at the unit inlet and outlet to allow easy draining of unit for winterizing and to provide easier access should servicing be required.

Electrical Connection

Always use a suitably qualified Electrician to perform any electrical work, they must read the manual before connecting.
Ensure all cabling, circuit breakers, and protections are of a suitable size and specification in accordance with electrical wiring legislation for the heater being installed. Ensure to check that there is adequate voltage and current available at the heater connection to run the unit.
Voltage range should be between 380-415 volts for 3 phase units. Voltage ranges outside these parameters will cause heater damage and void your warranty.

1. Ensure power is disconnected during installation or service.
2. Always comply with the national and local electrical codes and standards.
3. Ensure the electrical cable size is adequate for heater requirements at the installation location.
4. The heater must be equipped with a circuit breaker and isolation device.
5. The CS-i 65 has the ability to hard-wire a water pump directly to the heat pump. With this type of set up a circuit breaker must be installed between the heat pump and water circulation pump. Please note the heat pumps stated max. amp draw makes no allowance for the addition draw of the water pump that is hard wired to the heater. The CS-i 130 and CS-i 250 models connect to a water pump via an external relay, drawing its power from a separate power circuit.
6. The unit must be well earthed. Remove the front panel to access the electrical connection terminals of the heater. The electrical wiring diagram is affixed to the inside of the front panel or at the back of this manual.

Initial Start-up
For the unit to heat the pool, the filter pump must be running to circulate water through the heat exchanger.

After installation is completed, follow the steps below:

1. Turn on your filter pump. Check for water leaks and verify flow to and from the pool.
2. Turn on the electrical power supply to the unit, then press the ON/OFF key on the display, it should start after a few minutes.
3. After the system has been running for approximately 5 minutes; check the 2 temperatures displayed on the screen and review the Temperature Differential (TD). The small temperature displayed is the cold-water inlet temperature, the main temperature display is the heated water outlet.
4. Adjust the water flow by opening or closing the 3-way valve installed at the cold-water inlet to achieve a target TD of approximately 2°C (e.g. 22°C inlet water and 24°C outlet water).
5. After running a few minutes make sure the air leaving the top of the unit is cooler (between 5-10 ℃)
6. To test the correct operation of the unit’s flow switch, while the unit is turned on and operating, turn OFF the water pump that is supplying the unit with water. The unit should turn off automatically.
7. Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is reached. (Note: this may take up to several days depending on the initial water temperature and the size and location of the pool).

Time Delay
The unit is equipped with a 3-minute built-in solid-state restart delay included to protect control circuit components and to eliminate restart cycling and contactor chatter.
This time delay will automatically restart the unit approximately 3 minutes after each control circuit interruption. Even a brief power interruption will activate the solid state 3-minute restart delay and prevent the unit from starting until the 5-minute countdown is completed.
Power interruptions during the delay period will have no effect on the 3-minute countdown.

Troubleshooting

HEAT PUMP NOT WORKING? CHECK THE FOLLOWING:
IS THE SCREEN OF CONTROL PANEL LIT?
If not, make sure the electrical wires and cables are correctly connected and the power is on. Ensure any circuit breaker devices are set to the ON position and press the ON button on your controller. Check your controller cable is plugged in and is not damaged. If the unit has been shut off or the power has been interrupted the heater will not restart for a 5-minute period to protect the compressor. Wait 5 minutes before attempting a restart.

IS THE HEAT PUMP SET TO RUN AT THE CORRECT TIME & DATE?
Please check your current timing or temperature modes on your controller – you may have programmed the unit to turn on at a different time.

IS THERE ENOUGH WATER FLOW?
If the screen displays a water flow related error check the water flow. Is the water pump in operation and the system free of debris that may cause a blockage? Disconnect pool cleaners to ensure proper water flow.

DOES YOUR HEAT PUMP HAVE AN ERROR MESSAGE ON THE SCREEN?
If yes, refer to the error code table 19.

IS THE CURRENT POOL/SPA WATER TEMP HIGHER THAN THE SET TEMP ON THE CONTROLLER?
If so the unit will not operate until the pool/spa water temperature falls below the set temperature on the controller.

HEAT PUMP IS RUNNING BUT NOT HEATING, CHECK THE FOLLOWING:
IS THE AIR DISCHARGED FROM THE TOP OF THE FAN NOTICEABLY COOLER THAN THE AMBIENT TEMPERATURE?
If not, check the refrigerant gauge on the bottom panel of the heater. Another way to determine if the heater is working correctly is to look at the controller’s screen and check to see if the WATER OUT temp is higher than the WATER IN temp. Check also the INLET WATER TEMP is lower than the HEAT TEMP set point.
If the gauge shows less than 0.8MPA contact EvoHeat tech support to check the refrigerant system.

IS THE FAN FUNCTIONING?
If not contact EvoHeat tech support on 1300 859 933

Ensure sufficient fresh airflow around the unit as per installation instructions.
Make sure cold air discharged does not recycle back through the heater. Check the condenser fins. If they are dirty or blocked use a low flow garden hose only (Pressurised water may cause damage to the heater).
The unit will periodically defrost when the ambient air temperature is lower than 8 degrees.

IF THE HEAT PUMP IS RUNNING CONTINUOUSLY, CHECK THE FOLLOWING:

• Check the set temperature is at your desired level and that the pool water temperature is at or below this set point.
• Alternatively, this could be a possible electrical component failure – contact EvoHeat tech support.

WATER APPEARING AROUND THE BASE OF THE UNIT, CHECK THE FOLLOWING:
The water appearing around the base of your heat pump could be condensation or a possible water leak. To determine, check the following:

• Check the discharge for the presence of chlorine.

If the water has no chlorine then it is condensation and is it normal – see drainage and condensation for more information. If the water has chlorine, it is a water leak and you need to contact EvoHeat tech support.

• Turn the heater off & run the water pump continuously for a period of 2-4 hours.

If the water dries out, then it was condensation – see drainage and condensation for more information. If there is a continuous leak contact EvoHeat tech support.

Maintenance

F.A.Q

Can I clean the unit with any cleaning agents?

No, only use the cleaning agents recommended by EvoHeat to avoid damage to the unit.

What should I do if the supply cord is damaged?

If the supply cord is damaged, it must be replaced by a qualified service agent to ensure safety.

How should I store the unit?

The unit must be stored in a room without any continuously operating ignition sources to prevent potential hazards.

DO I NEED TO GET MY UNIT SERVICED?

It is recommended that you get your EvoHeat unit serviced once a year by your local certified air conditioning or refrigeration technician. If your unit is located in a coastal area, more frequent maintenance may be necessary. During the service, they will check the operational pressures of the refrigeration system and give the unit and fins a good clean to ensure maximum performance. Our commercial service plan offers on-time servicing by qualified and accredited EvoHeat technicians - in combination with our genuine EvoHeat replacement parts.

DO WE HAVE RECOMMENDED SERVICE AGENTS?

EvoHeat have a large database of recommended service agents. Please contact EvoHeat tech support on 1300 859 933 for your local service agent details.

SHOULD I CHECK MY UNIT REGULARLY?

We recommend checking the unit regularly to avoid potential issues and damage to your heat pump.

WHAT SHOULD I BE CHECKING REGULARLY?

Check the water inlet/outlets often for leaks. Avoid the condition of no water or air entering into the system, as this will influence unit’s performance and reliability. You should clear the pool/spa filter regularly to avoid damage to the unit as a result of the dirty or clogged filter. The area around the unit should be dry, clean and well ventilated. Make sure there is nothing blocking the airflow of the heater e.g. Leaf litter. Discharge all water in the water pump and water system, so that freezing of the water in the pump or water system does not occur. You should discharge the water at the bottom of water pump if the unit will not be used for an extended period. You should check the unit thoroughly and fill the system with water fully before using it for the first time after a period of time. Check the power supply and cable connection often, should the unit begin to operate abnormally, switch it off and contact the qualified technician

Energy Saving Tips
If pool water is allowed to cool significantly, it may take several days to return to the desired swimming temperature. For weekend use, it is more economical to maintain the pool water temperature at or near your desired swimming temperature.
If you do not plan to use your pool for a prolonged period, then you might choose to turn the heat pump completely off or decrease the temperature setting of the control several degrees to minimize energy consumption.

• Use an accurate pool thermometer. A difference of 2°C, between 26°C and 28°C, will significantly increase energy consumption.
• Monitor the water temp. of the pool in summer, you can reduce heat pump usage due to warmer temperatures.
• When the pool is not used for long periods, turn off the heat pump.
• Where possible, shelter the pool from prevailing winds with well-trimmed hedges or other landscaping or fencing.
• Always use a high-quality pool cover when practical. Besides providing a valuable water saving feature, a pool cover will dramatically reduce heat loss and reduce your pool heating running costs by up to 70%!

Advanced
CHECK THE AREA
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimised. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system. prolonged period of no usage.

PRESENCE OF FIRE EXTINGUISHER
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging

CHECKING FOR PRESENCE OF REFRIGERANT
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.

CABLING
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also consider the effects of aging or continual vibration from sources such as compressors or fans.

REPAIR TO INTRINSICALLY SAFE COMPONENTS
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use.
Intrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating. Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.

GENERAL WORK AREA
All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.

WORK PROCEDURES
Work shall be undertaken under a controlled procedure to minimise the risk of a flammable gas or vapour being present while the work is being performed.

VENTILATED AREA
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere. prolonged period of no usage.

DETECTION OF FLAMMABLE REFRIGERANTS
Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used.

LABELLING
Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.

NO IGNITION SOURCES
No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. No Smoking signs shall be displayed.

CHARGING PROCEDURES

In addition to conventional charging procedures, the following requirements shall be followed.

• Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them.
• Cylinders shall be kept upright.
• Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
• Label the system when charging is complete (if not already).
• Extreme care shall be taken not to overfill the refrigeration system.

Prior to recharging the system, it shall be pressure tested with OFN. The system shall be leak tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site. The safety wire model is 5*20_5A/250VAC, and must meet the explosion- proof requirements.
Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt consult the manufacturer’s technical department for assistance.

The following checks shall be applied to installations using flammable refrigerants:

CHECKS TO THE REFRIGERATION EQUIPMENT

• The charge size is in accordance with the room size within which the refrigerant containing parts are installed;
• The ventilation machinery and outlets are operating adequately and are not obstructed; If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;
• Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;
• Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.

CHECKS TO ELECTRICAL DEVICES
Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment, so all parties are advised.

Initial safety checks shall include:

• That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
• That there no live electrical components and wiring are exposed while charging, recovering or purging the system;
• That there is continuity of earth bonding.
  1. During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
  2. Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to cables, excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.

REPAIRS TO SEALED COMPONENTS
Ensure that apparatus is mounted securely.
Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to.

LEAK DETECTION METHODS
The following leak detection methods are deemed acceptable for systems containing flammable refrigerants.
Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 % maximum) is confirmed.
Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.
If a leak is suspected, all naked flames shall be removed/extinguished.
If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak. Oxygen free nitrogen (OFN) shall then be purged through the system both before and during the brazing process.

REMOVAL AND EVACUATION
When breaking into the refrigerant circuit to make repairs or for any other purpose conventional procedures shall be used. However, it is important that best practice is followed since flammability is a consideration. The following procedure shall be adhered to:

• Remove refrigerant;
• Purge the circuit with inert gas; Evacuate;
• Purge again with inert gas; Open the circuit by cutting or brazing.
• The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be “flushed” with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for this task.
• Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe-work are to take place.
• Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available. working on them.

RECOVERY
When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge is available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure relief valve and associated shut- off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt.
The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders.
If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.
Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the task is commenced.

DECOMMISSIONING

• Become familiar with the equipment and its operation.
• Isolate system electrically.
• Before attempting the procedure ensure that:
  • Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
  • All personal protective equipment is available and being used correctly;
  • The recovery process is always supervised by a competent person;
  • Recovery equipment and cylinders conform to the appropriate standards.
• Pump down refrigerant system, if possible.
• If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
• Make sure that cylinder is situated on the scales before recovery takes place.
• Start the recovery machine and operate in accordance with manufacturer’s instructions.
• Do not overfill cylinders. (No more than 80 % volume liquid charge).
• Do not exceed the maximum working pressure of the cylinder, even temporarily.
• When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
• Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.
