INCORRECT DRAINAGE
FOR CONDENSATE
Calorex Heat Pumps Ltd. · The Causeway, Maldon, Essex CM9 4XD, UK
a) Calorex Heat Pumps have water inlet/outlet connections as follows:
All models have fittings which enable the heat pump to be connected to
either 1 ½" or 50mm pipe work.
b) The heat pump is supplied with bungs fitted in the water connection
fittings These need to be removed before the heat pump is installed.
(See section 3.2).
c) The Calorex 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 section 3.1).
d) Suitable breakable couplings should be installed local to the heat pump.
e) If the heat pump is installed at a lower level than the pool then isolation
valves should be fitted.
f) A drain valve or plug should be fitted to the lower pipe to facilitate drain
down in the winter period.
g) Connections on all models are by 1 ½" or 50mm Female fittings. The
water in/water out pipes need to be glued into these connections using a
suitabe adhesive.
h) The condensate drain at the base of the unit collects condensation from
the evaporator fins. This should run away to waste via ¾" domestic
waste piping. It is therefore necessary to ensure that the Calorex Heat
Pump is placed on a level plinth so that the condensate water can run
away with adequate fall to waste i.e. ½" per foot minimum and must
incorporate a "u" trap as to not overflow the edges of the drip tray inside
the heat pump. See below.
