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 consistsof 4 models. Heat pumps in this manual are designed to heat pool water and spas within therange of 10°C to 40°C. Standard units are suitable for outdoor pools operating in ambienttemperatures from 7°C to 40°C. Reverse Cycle Defrost models are available with operationdown 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 highlycorrosion resistant material. The heat pumps are suitable for use in fresh water and saltwater pools.The compressors fitted in the heat pumps are the scroll type and are known forquiet 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 externalfaults. Indicator lamps indicate operating mode. An adjustable digital thermostat controlswater 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 vapourcompression cycle (similar to that employed in a conventional refrigerator), in addition to operating as an activesolar collector.
Cooled Air Exhaust Compressor

Outside Air Evaporator(Heat Collector)
Pool Filter
SwimmingPool
Condenser Heat Tranferedto Pool Water
Pool WaterPump
Pool Water
The EVAPORATOR collects heat fromthe outside ambient air, pre-heated by thesun. With Calorex, swimming pool heatpumps high volumes of outside air aredrawn into the unit by the fan and expelledthrough the evaporator fins. The evaporatorhas liquid refrigerant passing through it,which is at a considerably lowertemperature than the ambient air, thereforethe air gives up its heat to the refrigerant,which then vaporizes.This pre-heated vapour now travels to-
The COMPRESSORwhere it is compressed andupgraded to a much highertemperature.The hot vapour now enters -
The CONDENSER where it issurrounded by the pool water. The heatis given up to the cooler pool water andthe now cooler refrigerant returns to itsformer liquid state but still under highpressure from the compressor.This pressure is released by passingthe liquid through -
The EXPANSION DEVICEand from there, now at lowpressure, it is returned to theevaporator and the cycle startsagain.
Coefficient of Performance
The efficiency of a Heat Pump is usually called its 'Coefficient of Performance' - (C.O.P.) which issimply a ratio of heat output to energy input, both being expressed in kW. Thus a Heat Pumpabsorbing 1 kW of electricity, collecting 4 kW of energy from the air, and delivering 5 kW of heat tothe 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 inpresence 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 timberfloor.
e Ensure water cannot collect under unit, it is recommend that units are installed on plinths 100mm abovefinished 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 givento siting the heat pump in order to minimise the noise coming from the machine, for example by positioningthe 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 cannotre-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 beadded together to form one inlet aperture. BUT discharge from each unit must be kept separate and must notbe incorporated into one common duct system.
Required Free Areas to provide air flow toand from heat pumps when installed in anenclosed area or where required to pass airthrough a wall, etc.
Free area is the available area through which aircan 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 beforethe 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 existingheater is being retained, then the Calorex Heat Pump should be connected between the filter and the otherheater. (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 tightenedonly, 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. Thisshould be run away to waste via ¾" domestic waste piping. It is therefore necessary to ensure that theCalorex unit is placed on a level plinth so that the condensate water can run away with adequate fall towaste ie.½" per foot min and must incorporate a 'u' trap as to not overflow the edges of the drip-tray insidethe machine. See figure 3.
Page 8
h. When the pipework installation is complete the pool pump should be switched on and the system tested forleaks. Also check the filter gauge to see that there is not an excessive increase in back pressure. Ifeverything 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 byheat pump (see data sheet).
j. All pipework must be adequately supported with allowance for expansion/contraction especially with plasticpipework.
k. It is recommended that when installing water systems the last connections to be made in the systemshould 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 pumpunless installation is as per Filter dosing (See figure 4). This includes the practice of dosingchemicals direct into Skimmer Basket, which results in concentrated corrosive liquids passing overmetal components.
2. Water quality must be maintained as follows:
pH: 7.4 ± 0.4Total Alkalinity: 80 - 120 ppm as CaCo3
Total Hardness: 100 - 300 ppm as CaCo3
Total dissolved solids: Max. 3000 ppmSaline Water Maximum concentration 6% wt/wtChlorine - free Cl range 1.0 - 3.0 ppmOzone 0.8 - 1.0 ppmBromine 2 - 3 ppmBaquacil 25 - 50 ppmAquamatic Ionic Purifier Maximum 2 ppm CopperTam Pure Purifier Maximum 2 ppm CopperSherwood 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 thecirculating pump need only run when required and this can be at a time preferred by the customer, i.e. in theEconomy 7 period.
All electrical work to be carried out in accordance with l.E.E. standards, latest issue, or local codes of practiceas 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 ofmachine.†
All units must be correctly earthed-grounded. An earth leakage trip of the Current operating type (30mA) isrecommended 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 inperformance or warranty terms:
Minimum MaximumVoltageSingle phase machines 207V 253VThree-phase machines 360V 440VCycle 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 and8 that to work on part of the intallation the supply to all parts of the installation must beisolated.
Three phase units are fitted with a phase protection relay and will not run if phases areconnected incorrectly. A red lamp on the phase rotation relay in the electric box isilluminated when the phases are correctly connected.

WINTERISING PROCEDURE
ALL MODELS
Objective
To provide frost protectionTo eliminate corrosion problemsTo inhibit electrical components
1. Switch off electric supply to heat pump.
2. Remove external fuses and keep in safe place away from heat pump to prevent accidental operation of heatpump.
3. Ensure water circulation pump is switched off.
4. Drain water from heat pump by:
a. drain valve if fitted
b. disconnecting pipework to and from heat pump
5. Flush through water circuit in heat pump by using CLEAN TAP WATER (NOT POOL WATER) via hose intooutlet connection - run the hose for 10 minutes minimum; use spray nozzle if available.
6. Allow to drain - when drained, fit plastic bags secured by elastic bands over water connections.
7. Uncover electrical enclosure (see page 12) and liberally spray interior of unit, with moisture-repellantaerosol WD40 or similar; reseal enclosure.
8. If heat pump located outside, protect from weather by covering with VENTILATED cover. Do not use plasticsheet as condensation could occur within unit.
WARNING. Isolate machine before removing covers! The heat pumpembodies electrical and rotational equipment, it is recommended for your
own safety that a competent person carries out the following procedure
N.B. If this procedure is not adopted and frost or corrosion damage results then thewarranty will become invalid.
Page 28
START UP PROCEDURE AFTER WINTERISATION
1. Replace covers (if not fitted).
2. Remove front grille .Using a soft brush clean finned surfaces of heat pump. Replace panel.
3. Remove plastic covers on water connections and reconnect water piping or close drain valve.
4. Start up water circulating pump and leave running for at least 1/4 hour to establish flow and enable any airin piping to escape.
5. Replace fuses to heat pump circuit.
6. Switch on heat pump.
7. Check control thermostat is set to required pool temperature.
8. Check pool water daily to ensure it is at correct pH and has correct chemical balance. See Section 3Plumbing.
