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. -
Page 6: How The Heat Pump Works
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. -

Allow adequate clearance to service panels on unit; recommend 500mm minimum. 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. -
Page 8: Air Flow
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) FIG 1 POSSIBLE POSITIONS OF A CALOREX 31 UNIT Suitable opening Suitable opening CALOREX 31 >... -

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. - Page 10 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. 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).
