Information on servicing
Checks to 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.
Work procedure
Work shall be undertaken under a controlled procedure so as to minimise the
risk of a flammable gas or vapour being present while the work is being
performed.
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.
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.
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
area.
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.
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.
Checks to the refrigeration equipment
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:
– 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 no live electrical components and wiring are exposed while charging,
recovering or purging the system;
– that there is continuity of earth bonding.
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.
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.
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 ageing or continual vibration from
sources such as compressors or fans.
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.
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.
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.
Decommissioning
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.
a) Become familiar with the equipment and its operation.
b) Isolate system electrically.
c) 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 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.
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.
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 are 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.
DISPOSAL
Electrical products should not be disposed of with household waste. Please
recycle where facilities exist. Check with your local authority or retailer
for recycling advice.
The Pool Heater contains refrigerant. As it is a harmful substance, the
refrigerant must be disposed of properly at a collection point approved for
this purpose.
SETUP
CHECK LIST
To check the parts included in the box, consult the parts list in this manual.
Verify that the equipment components represent the model that you had intended
to purchase. In case of any damaged or missing parts at the time of purchase,
visit our website bestwaycorp.com/support.
CHOOSE THE CORRECT LOCATION
The Pool Heater will work properly in any location under the following
conditions:
– The Pool Heater must be located 2m away from the pool and 1m away from any
objects.
– Always hold the Pool Heater upright. If the device has been held in a
different position, to stabilize the liquid gas inside the system, wait at
least 24 hours before starting to use it.
– Never install the unit closed to shrubbery that could block the air inlet.
Such locations impair the continuous supply of fresh air, resulting in reduced
efficiency and possibly preventing sufficient heat output.
– The Pool Heater has a fan to expel cold air. Make sure to position the Pool
Heater so that the cold air will not go in the direction of the pool.
– Place the Pool Heater near a drain point. The air drawn into the Pool Heater
is strongly cooled by the operation for heating the pool water, which may
cause condensation on the evaporator.
The amount of condensation may be as much as several liters per hour at high
relative humidity. This is sometimes mistakenly regarded as a water leak.
INSTALLATION
For the installation, follow the instructions in this manual. Drawings in the
assembly section are for illustration purposes only and may not reflect actual
product. Not to scale.
RECOMMENDATIONS DURING THE INSTALLATION
– In order to heat the water in the pool, the Filter Pump must be running to
circulate the water through the Pool Heater. It will not start up if the water
is not circulating.
– If a chlorinator or other equipment that produces chemicals is installed in
the system, it must be installed after the Pool Heater. This will help avoid a
high level of chemicals, which can damage the metal part of the Pool Heater.
– Before connecting the unit, verify that the supply voltage matches the
operating voltage of the Pool Heater.
– When connecting the plug to the wall socket, ensure the power plug is
secure. If the plug is not secure, it may cause an electric shock, over-
heating or fire.
– Never pull out the power plug during operation. Otherwise, it may cause an
electric shock or a fire due to over-heating.
– Heat pump equipotential bonding terminal
It is recommended to arrange for a qualified electrician to connect the heat
pump to an equipotential bonding terminal using a minimum 2.5mm2 solid copper
conductor.
USING THE POOL HEATER
– Switch on the filter pump. Check for leaks and verify that water is flowing
from and to the swimming pool.
– Connect power to the heat pump and press the On/Off button on the control
panel. The unit will start up.
– When first powered on, the Pool Heater will check the water flow in 30
seconds, then start running if the water flow is ok.
– The heat pump has a built-in, 3-minute start-up delay to protect the
circuitry and avoid excessive contact wear. The unit will restart
automatically after this time delay expires.
– After a few minutes, check whether the air blowing out of the unit is
cooler.
– When turning off the filter pump, the unit should also turn off
automatically.
– Depending on the initial temperature of the water in the swimming pool and
the air temperature, it may take some time to heat the water to the desired
temperature. A good swimming pool cover can dramatically reduce the required
length of time.
