PLUMBING

a. Calorex '29' 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.
