AIR/WATER HEAT PUMPS FOR SWIMMING POOLS
MODELS AW631, 831,1231, 1531
The Calorex ‘31’ range of air/water heat pumps is for swimming pool applications and consists
of 4 models. Heat pumps in this manual are designed to heat pool water and spas within the
range of 10°C to 40°C. Standard units are suitable for outdoor pools operating in ambient
temperatures from 7°C to 40°C. Reverse Cycle Defrost models are available with operation
down to -15ºC, these machines are suitable for heating indoor pools or spas all year round.
The water heat exchanger is a full flow type, manufactured from titanium, which is a highly
corrosion resistant material. The heat pumps are suitable for use in fresh water and salt
water pools.The compressors fitted in the heat pumps are the scroll type and are known for
quiet running. With these features the heat pump is designed to have a long, trouble free life.
All units have integral safety devices to protect the heat pump from internal and external
faults. Indicator lamps indicate operating mode. An adjustable digital thermostat controls
water temperature. Also a 6 minute cycle time delay is incorporated.

HOW THE HEAT PUMP WORKS
The CALOREX Swimming Pool Heat Pump provides thermodynamic heating by means of a vapour
compression cycle (similar to that employed in a conventional refrigerator), in addition to operating as an active
solar collector.

The EVAPORATOR collects heat from
the outside ambient air, pre-heated by the
sun. With Calorex, swimming pool heat
pumps high volumes of outside air are
drawn into the unit by the fan and expelled
through the evaporator fins. The evaporator
has liquid refrigerant passing through it,
which is at a considerably lower
temperature than the ambient air, therefore
the air gives up its heat to the refrigerant,
which then vaporizes.
This pre-heated vapour now travels to-
The COMPRESSOR
where it is compressed and
upgraded to a much higher
temperature.
The hot vapour now enters -
The CONDENSER where it is
surrounded by the pool water. The heat
is given up to the cooler pool water and
the now cooler refrigerant returns to its
former liquid state but still under high
pressure from the compressor.
This pressure is released by passing
the liquid through -
The EXPANSION DEVICE
and from there, now at low
pressure, it is returned to the
evaporator and the cycle starts
again.
Coefficient of Performance
The efficiency of a Heat Pump is usually called its 'Coefficient of Performance' - (C.O.P.) which is
simply a ratio of heat output to energy input, both being expressed in kW. Thus a Heat Pump
absorbing 1 kW of electricity, collecting 4 kW of energy from the air, and delivering 5 kW of heat to
the pool water is said to have a C.O.P. of 5:1.
Naturally this ratio will vary according to the temperature of the water and the ambient air.

INSTALLATION
1. SITING
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 the evaporator (finned side) to ensure that it is undamaged.
(Minor indentations in the fins do not affect performance). If severely damaged, endorse delivery note in
presence of the driver and send a recorded delivery letter to transport company giving details.
c Protect unit if installation is delayed.
d Provide a firm level base capable of supporting operational weight of unit; spread load if mounted on timber
floor.
e Ensure water cannot collect under unit, it is recommend that units are installed on plinths 100mm above
finished floor level. This also aids condensate drainage.
f Allow adequate clearance to service panels on unit; recommend 500mm minimum.
g All Calorex heat pumps are by design as quiet as is practical, however due consideration should be given
to siting the heat pump in order to minimise the noise coming from the machine, for example by positioning
the machine so that the inlet/outlets are parallel to occupied premises.
h Ensure loose debris such as leaves, grass cuttings, etc will not block air inlet grilles.
i Consider protection from extreme weather conditions if installed externally, i.e. lean-to-cover or building.

Page 6
2. AIR FLOW
Due consideration must be given to air flow, i.e. do not obstruct inlet or outlet and ensure discharge air cannot
re-circulate to inlet. (See figure 1)

Note: If multiple units are installed in an enclosed area then the inlet free areas required for each unit can be
added together to form one inlet aperture. BUT discharge from each unit must be kept separate and must not
be incorporated into one common duct system.
Required Free Areas to provide air flow to
and from heat pumps when installed in an
enclosed area or where required to pass air
through a wall, etc.
Free area is the available area through which air
can pass through a grille or louvres.

3. PLUMBING
a. Calorex '31' range Heat Pumps have water inlet/outlet connections as follows:
All models have 1½ " BSP parallel, male threads.
The machine is supplied with bungs fitted in the water connection fittings. These need to be removed before
the unit is installed. See Section 4.
b. The Calorex Pool Heat Pump must be connected after the filter in the return pipe to the pool. If an existing
heater is being retained, then the Calorex Heat Pump should be connected between the filter and the other
heater. (See figure 4).
c. Suitable breakable couplings should be installed local to heat pump.
d. If the heat pump is installed at a lower level than pool water then isolation valves should be fitted.
e. Drain valve or plug should be fitted to the lower pipe to facilitate drain down in winter period.
f. Connections on all models are by BSP parallel, male threaded fittings. These should be hand tightened
only, otherwise damage may result to the threads of the plastic fittings.
g. The condensate drain at the base of the unit collects the condensation from the evaporator fins. This
should be run away to waste via ¾" domestic waste piping. It is therefore necessary to ensure that the
Calorex unit is placed on a level plinth so that the condensate water can run away with adequate fall to
waste ie.½" per foot min and must incorporate a 'u' trap as to not overflow the edges of the drip-tray inside
the machine. See figure 3.

Page 8
h. When the pipework installation is complete the pool pump should be switched on and the system tested for
leaks. Also check the filter gauge to see that there is not an excessive increase in back pressure. If
everything is then working normally the water circulating system is ready to use.
i. Water circuit to and from unit to be capable of maintaining within specified limits the rate of flow required by
heat pump (see data sheet).
j. All pipework must be adequately supported with allowance for expansion/contraction especially with plastic
pipework.
k. It is recommended that when installing water systems the last connections to be made in the system
should be the breakable connections to avoid any stresses on to the unit connections.
IMPORTANT
1. All Pool Purifying Devices and Chemical Injection Systems to be fitted down stream of heat pump
unless installation is as per Filter dosing (See figure 4). This includes the practice of dosing
chemicals direct into Skimmer Basket, which results in concentrated corrosive liquids passing over
metal components.
2. Water quality must be maintained as follows:
pH: 7.4 ± 0.4
Total Alkalinity: 80 - 120 ppm as CaCo3
Total Hardness: 100 - 300 ppm as CaCo3
Total dissolved solids: Max. 3000 ppm
Saline Water Maximum concentration 6% wt/wt
Chlorine - free Cl range 1.0 - 3.0 ppm
Ozone 0.8 - 1.0 ppm
Bromine 2 - 3 ppm
Baquacil 25 - 50 ppm
Aquamatic Ionic Purifier Maximum 2 ppm Copper
Tam Pure Purifier Maximum 2 ppm Copper
Sherwood Purifier Maximum 2 ppm Copper
3. Maximum pressure of water in heat pump circuit should not exceed 3.5kg/cm2(50 psi)

5. ELECTRICAL (MACHINE WIRING AND SUPPLY).
SEE FIGURES 5,6,7 AND 8 FOR PREFERRED METHOD
Use of the Calorex Energy Management Controller will enable greater savings to be made because the
circulating pump need only run when required and this can be at a time preferred by the customer, i.e. in the
Economy 7 period.
All electrical work to be carried out in accordance with l.E.E. standards, latest issue, or local codes of practice
as applicable.
The machine should be installed in line with EMC2004/108/EC.
Protected supply to incorporate fuses (Type GU, FAZC) or motor (type C) circuit breakers to specified rating,
(see Data Sheet). H.R.C. fuses are recommended. An isolator must be fitted within 2m and in sight of
machine.†
All units must be correctly earthed-grounded. An earth leakage trip of the Current operating type (30mA) is
recommended to be fitted to all pool electrics.
INCONSISTENT ELECTRICAL SUPPLY
The following limits of operation must not be exceeded if Calorex machines are to be guaranteed either in
performance or warranty terms:
Minimum Maximum
Voltage
Single phase machines 207V 253V
Three-phase machines 360V 440V
Cycle frequency 47.5Hz 52.5Hz
N.B. This voltage must be available at the heat pump whilst running.
† Note the isolator must have a minimum of 3mm air gap when turned off.
IMPORTANT:-
The user should be made aware that on all the installations shown by figures 5, 6, 7 and
8 that to work on part of the intallation the supply to all parts of the installation must be
isolated.
Three phase units are fitted with a phase protection relay and will not run if phases are
connected incorrectly. A red lamp on the phase rotation relay in the electric box is
illuminated when the phases are correctly connected.
