3. Repairs to sealed components

   • 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 absolutely 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.
   • 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.
   • 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 working on them.

4. 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.

5.  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 take into account the effects of aging or continual vibration from sources such as compressors or fans.

6. 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.

7. Leak detection methods

   • Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need recalibration. (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.

8. 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

9. 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 minimize 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.

10. Decommissioning

    • Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details.

    • 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.
      a) Become familiar with the equipment and its operation.
      b) Isolate system electrically.

      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 supervised at all times by a competent person; recovery equipment and cylinders conform to the appropriate standards.
      d) Pump down refrigerant system, if possible.
      e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
      f) Make sure that cylinder is situated on the scales before recovery takes place.
      g) Start the recovery machine and operate in accordance with manufacturer’s instructions.
      h) Do not overfill cylinders. (No more than 80 % volume liquid charge).
      i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
      j) 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.
      k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

11. Labelling

    • Equipment shall be labelled stating that it has been decommissioned 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.

First time start-up

Note- In order for the unit to heat the pool (or spa), the filter pump must be running so that the water can circulate through the heat pump. Without this circulation, the heat pump will not start.

When all connections have been made and checked, the following steps should be followed:

1. Turn on the filter pump. Check for leaks.
2. Turn on the electrical power supply to the unit, then press the ON/OFF key on the electronic control panel. The unit should start when the time delay period has elapsed.
3. When the unit has been running for a couple of minutes, check if the air leaving the unit is cooler than the ambient temp.
4. Check the performance of the flow switch as follows: with the unit running turn the filter pump off. The unit should also switch off automatically.
5. The unit and the filter pump should run 24 hours a day until the desired pool water temperature has been reached. Once the set temperature is reached, the unit will switch itself off. As long as the filter pump is running, the unit will restart automatically when the temperature of the pool water drops more than 1°C below the set temperature.

Depending on the starting temperature of the pool water and the air temperature, it can take several days for the water to reach the desired temperature. Covering the pool can drastically reduced this period.

Water flow switch —the unit is equipped with a flow switch that is switched on when enough water has flowed through the unit and that is switched off when the water flow becomes too low. (E.g. When the filter pump is switched off).

Time delay— the unit is equipped with a built-in 3-minute start delay included to protect electrical components and contacts. After this time delay, the unit will automatically be restarted. Even a brief interruption of the power supply will activate the start delay and prevent the unit from starting immediately. Additional interruptions of the power supply during the delay period will have no effect on the 3-minute countdown.

Protection systems

Water flow switch

Equipped with flow switch the heat pump will not work when the filter pump is not working (and the water is not circulating).
This system prevents the heat pump from heating only the water present in the heat pump itself. The protection also stops the heat pump if water circulation is cut off or stopped.

Refrigerant gas high and low pressure protection

The high pressure protection makes sure the heat pump is not damaged in case of over pressurisation of the gas. The low pressure protection emits a signal when refrigerant is escaping from the conduits and the unit can not be kept running.

Overheating protection on the compressor

This protection protects the compressor from overheating.

Automatic defrost control

When the air is very humid and cold, ice can form on the evaporator. In that event, a thin layer of ice appears that will grow increasingly bigger as long as the heat pump is running. When the temperature of the evaporator has become too low, automatic defrost control will be activated, which will reverse the heat pump cycle so that hot refrigerant gas is sent through the evaporator during a brief period of time to defrost it.

Temperature difference between inflowing and outflowing water

During normal operation of the heat pump, the temperature difference between inflowing and outflowing water will approximate 1 to 2℃.In the event that the pressure switch does not work and that the water stops circulating, the temperature probe monitoring the outflowing water will always detect a rise in temperature. As soon as the temperature difference between inflowing and outflowing water exceeds 13℃, the heat pump will be automatically turned off.

Low temperature cut-out

If, during cooling, the temperature of the outflowing water reaches 5℃ or drops below this temperature, the heat pump will turn itself off until the water temperature reaches or exceeds 7℃ again.

Anti-frost protection during winter

This protection can only be activated if the heat pump is in STAND-BY status.

First anti-frost protection

If the filter pump is controlled by the heat pump (regardless of the value for parameter 9) and when the water temperature lies between 2 and 4℃,and the air temperature is lower than 0℃,the filter pump will be automatically turned on to prevent the water from freezing in the piping. This protection is deactivated when the temperature rises again.

Second anti-frost protection

If the water temperature drops even more, that is, below 2℃ (during long frost periods), the heat pump will also start running to heat the water until its temperature approximates 3℃.When this temperature is reached, the heat pump will stop, but anti-frost protection will remain active until conditions change.

Heat pump winterizing

Important: failure to take the necessary precautions for winterizing can damage the heat pump, which will invalidate the warranty.

The heat pump, filter pump, filter and conduits must be protected in areas where the temperature can drop below freezing point. Evacuate all water from the heat pumps as follows:

1. Disconnect the electrical power supply to the heat pump
2. Close the water supply to the heat pump completely.
3. Disconnect water inlet and outlet coupling fittings of the heat pump and let the water drain out of the unit. Make sure all water is out of the heat pump.
4. Loosely reattach water inlet and outlet coupler fittings to the heat pump in order to prevent dirt from setting into the conduits.

Note: these precautions should not be taken if you choose to use the built-in anti-frost protection.

Restarting the pump after winter

If you emptied the heat pump for winterising, follow the steps below to restart it in spring:

1. First check that there is no dirt in the conduits and that there are no structural problems
2. Check that the water inlet and outlet fittings are adequately fastened. Check that ”water inlet” and ” water outlet” are correct according to the lables on the heat pump. (Water out from the filter unit = water inlet on heat pump)
3. Start the filter pump to start the water flow to the heat pump. Adjust the by-pass so there is enough water through the heat pump. Normally on small filter system the by-pass can be closed, so all circulated water goes through the heat pump.
4. Reconnect the electrical power supply to the heat pump and turn the heat pump ON.

Check-up

Our heat pumps have been built and developed to last long if they have been installed correctly and can operate in normal conditions. Regular check-ups are important if you want your heat pump to function efficiently for many years. Below are some recommendations to ensure optimal working conditions for your heat pump.

1. Make sure that the service panel is easily accessible.
2. Keep the area surrounding the heat pump free of organic waste.
3. Prune any vegetation around the heat pump so that there is sufficient free space around the pump.
4. Remove any water sprinklers that are near the heat pump as they could cause daectly onto the heat pump from a roof. Install proper drainage.
5. Prevent rain from running directly onto the heat pump from a roof. Install proper drainage.
6. Do not use the heat pump if it has been flooded. Immediately contact a qualified technician to inspect the heat pump and carry out necessary repair.

Condensation can occur when the heat pump is running. This condensation water can flow away through an opening in the base pan of the unit. The amount of condensation water will increase when humidity is high. Remove any dirt that could block the water outlet on the bottom pan. 5 to 20 liters per day of condensation water can be produced while the unit is running. If more condensation is produced, stop the heat pump and wait for one hour before checking for water leakage (Let the filter pump keep running).

Note: a quick way to verify that the water running is because of the condensation. Shut off the unit and keep the pool pump running. If the water stops running out, it is condensation. AN EVEN QUICKER WAY IS TO TEST THE DRAIN WATER FOR CHLORINE. If no chlorine is detected, the drain water is a result of condensation.

Also make sure that the air in and out passages are free, and prevent air out from immediately re-entering to the air in. (It is important to have min. 2m free space at the air out side of the heat pump).

Maintenance and Inspection

The picture below shows a heat pump with lid (top panel) off.
Do not open the Lid (Top panel) when the electrical power is connected to the heat pump.

Important:
The Power out 230V should NOT be used for connecting your filter pump

Troubleshooting guide

Incorrect installation may result in an electrical charge that could lead to death or serious injury of users, installers or others by electrical shock and it may also cause damage to heat pump.
DO NOT attempt to modify the internal configuration of the heat pump.

1. Keep your hands and hair clear of the fan blades to avoid injury.
2. If you are not familiar with your pool filtration system and heat pump:
   a. Do not attempt to carry out any adjustment or service without consulting your dealer, pool professional or air conditioning contractor.
   b. Read the entire installation manual before attempting to use, service or make adjustments to the unit.
   c. Wait for 24hours after the installation before starting the heat pump to prevent damage to the compressor. (If the heat pump has been transported and carried all the time with the feet down, it can be started immediately).

Note: Switch off the power before carrying out any maintenance or repairs.

IMPORTANT REMARK: if a malfunction cannot be resolved immediately, in order to analyse the problem we will need to know the message (error code) that is showing on the display controller as well as the values for the settings (parameters 0-A). We also need to know the status of the heat pump: the ambient temperature, water inlet / outlet temperature, if there is cold air coming out from the heat pump, if the grill (evaporator) is cold, or if there is ice on the heat pump.
