1.1 FUNCTION
The Calorex Swimming pool heat pump provides ermodynamic heating
by means of a vapour compression cycle, (similar to at employed in a
conventional refrigerator), in addition to acting as an active solar collector.
COEFFICIENT OF PERFORMANCE
The eciency of a Heat Pump is usually called its ‘Coecient of Performance’
- (C.O.P.) which is simply a ratio of heat output to energy input, bo being
expressed in kW. Thus a Heat Pump absorbing 1 kW of electricity, collecting
4kW of energy from e air, and delivering 5kW of heat to e pool water is
said to have a C.O.P. of 5:1.
This ratio will vary according to e temperature of e water and e ambient
air.
THE HEAT PUMP CYCLE
1. THE EVAPORATOR collects e heat from e outside ambient air, pre-heated by e
sun. In e Calorex swimming pool heat pumps, high volumes of outside air are drawn into
e unit by e fan expelled rough e evaporator fins. The evaporator has liquid refrigerant
passing rough it which is at a considerably lower temperature an e ambient air.
Therefore e air gives up its heat to e refrigerant which en vaporises.This preheated
vapour now travels to -
3. THE CONDENSER where it is surrounded by e pool water.
The heat is given up to e cooler pool water and e now cooler
refrigerant returns to its former liquid state but still under high
pressure from e compressor. This pressure is released by passing
liquid rough-
1. THE COMPRESSOR where it is
compressed and upgraded to a much
higher temperature. The hot vapour now
enters-
4. THE EXPANSION DEVICE and from ere, now at
normal pressure, it is returned to e evaporator and
e cycle starts again.

2.0 INSTALLATION
a) Ensure heat pump on site is as ordered, i.e. model, electrical supply and
factory fitted options.
b) Inspect unit for damage, in particular inspect e evaporator (finned side)
to ensure at it is undamaged. (Minor indentations in e fins do not affect
performance). If severely damaged, endorse delivery note in presence of e
driver and send a recorded delivery letter to transport company giving details.
Protect unit if installation is delayed.
2.1 ACCESSORIES
The heat pump is supplied wi accessories which aid installation. On delivery
e accessories are in a plastic bag in e heat pump electric box. (See section
4.2 for lid removal).
These accessories are as follows:
4 x rubber feet - Fit ese under e metal feet of e heat pump to help
reduce e effects of vibration.
2 x 50mm female connectors - On delivery e heat pump has 1½” sockets
attached to e water connections for fitting 1 ½” plastic pipes. If 50mm
pipework is preferred undo e readed couplings on e water in/out
connection points and carefully remove e 1 ½” sockets. Then fit e 50mm
sockets in eir place and refit e readed couplings. The heat pump can en
be fitted wi 50mm plastic pipe.
2 x Condensate drain piece - Condensate drain pieces are supplied suitable for
¾” or 20mm pipe. Use whichever piece fits e drain pipe required. Glue e
relevant piece to e driptray outlet and en fit en condensate drain piping.
2.2 SITING
a) Provide a firm level base capable of supporting operational weight of unit;
spread load if mounted on timber floor.
b) Ensure water cannot collect under unit, it is recommend at units are
installed on plins 100mm above finished floor level. This also aids condensate
drainage.
c) Allow adequate clearance to service panels on unit; recommend 500mm
minimum.
d) All Calorex heat pumps are by design as quiet as is practical, however due
consideration should be given to siting e heat pump in order to minimise e
noise coming from e machine, for example by positioning e machine so at
e inlet/outlets are parallel to occupied premises.
e) Ensure loose debris such as leaves, grass cuttings, etc will not block air inlet
grilles.
f) Consider protection from extreme weaer conditions if installed externally,
i.e. lean-to-cover or building.

2.3 AIR FLOW
IMPORTANT
If multiple units are installed in an enclosed area en e inlet free areas
required for each unit can be added togeer to form one inlet aperture. BUT
discharge from each unit must be kept separate and must not be incorporated
into one common duct system.
Table 1
Model Minimum Free Area m2
Inlet Discharge
PPT16 0.322 0.173
PPT22 0.322 0.173
Due consideration must be given to air flow i.e. do not obstruct inlet or outlet
and ensure discharge to air cannot recirculate to inlet. (See below).
Required Free Areas to provide air flow to and from heat pumps when installed
in an enclosed area or where required to pass air rough a wall etc.
Free areas is e available area rough which air can pass rough a grille or
louvres.

3.0 PLUMBING
a) Calorex Heat Pumps have water inlet/outlet connections as follows:
All models have fittings which enable e heat pump to be connected to eier
1½” or 50mm pipe work.
b) The heat pump is supplied wi bungs fitted in e water connection fittings
These need to be removed before e heat pump is installed. (See section
3.2).
c) The Calorex Heat Pump must be connected aer e filter in e return pipe
to e pool. If an existing heater is being retained, en e Calorex Heat
Pump should be connected between e filter and e oer heater. (See
section 3.1).
d) Suitable breakable couplings should be installed local to e heat pump.
e) If e heat pump is installed at a lower level an e pool en isolation
valves should be fitted.
f) A drain valve or plug should be fitted to e lower pipe to facilitate drain
down in e winter period.
g) Connections on all models are by 1½” or 50mm Female fittings. The water
in/water out pipes need to be glued into ese connections using a
suitable adhesive.
h) The condensate drain at e base of e unit collects condensation from e
evaporator fins. This should run away to waste via ¾” domestic waste
piping. It is erefore necessary to ensure at e Calorex Heat Pump is
placed on a level plin so at e condensate water can run away wi
adequate fall to waste i.e. ½” per foot minimum and must incorporate a “u”
trap as to not overflow e edges of e drip tray inside e heat pump.
See below.
) When e pipework installation is complete e pool pump should be
switched on and e system tested for leaks. Also check e filter gauge to
see at ere is not an excessive increase in back pressure. If everying is
en working normally e water circulating system is ready for use.
j) Water circuit to and from e unit is to be capable of maintaining wiin
specified limits e rate of flow required by e heat pump. (See section 9).
k) All pipework must be adequately supported wi allowance expansion/
contraction especially wi plastic pipework.
l) It is recommended at when installing water systems e last connections
to be made in e system should be breakable connections to avoid any
stresses on e unit connections.
IMPORTANT
1. All Pool Purifying Devices and Chemical Injection Systems to be fitted down
stream of e heat pump (see section 3.1) unless installation is as per filter
dosing. This includes e practice of dosing chemicals direct into skimmer
basket, which results in concentrated corrosive liquids passing over
vulnerable metal components.
2. Water quality must be maintained as follows:
3. Maximum pressure of water in heat pump circuit should not exceed 3.5bar
for PPT16/22 (50 psi).

4.0 ELECTROLYTIC CORROSION IN SWIMMING POOLS
Electrolytic corrosion will occur when dissimilar metals at are in contact wi
each oer create a potential difference between emselves. Sometimes
separated by a conductive substance known as an electrolyte, e dissimilar
metals will create a small voltage (potential difference) at allows e ions of
one material to pass to e oer.
Just like a battery, ions will pass from e most positive material to e more
negative material.
Anying more an 0.3 volts can cause e most positive material to degrade.
A swimming pool wi its associated equipment can create is effect. The pool
water being an ideal electrolyte and components of e filtration circuit, heating
system, steps, lights etc providing e dissimilar metals needed to complete e
circuit.
Whilst ese small voltages are rarely a safety reat, ey can create premature
failure rough corrosion. Not dissimilar to corrosion rough oxidation, electrolytic
corrosion can cause complete failure of a metallic material in a very short period
of time.
In order to prevent is type of corrosion all metallic components in contact wi
swimming pool water should be bonded togeer using 10mm² bonding cable.
This includes non-electrical items such as metal filters, pump strainer boxes,
heat exchangers, steps and handrails. It is highly recommended at bonding be
retrofitted to existing pools, which may not be protected by is system.
