Calorex Pro-Pac PPT45EHC - Plumbing and Water Connections

3. PLUMBING
The Calorex pool heat pump must be connected aer e filter in e
return pipe to e pool. If an existing heater is being retained, en e
Calorex should be connected between e filter and e oer heater.
(See Figures 3 & 4).
1. Calorex heat pumps have water inlet/outlet connections as follows:
2. Suitable breakable couplings should be installed local to heat pump.
3. If heat pump installed at lower level an pool water en isolation
valves should be fitted
4. A drain valve or plug should be fitted to lower pipe to facilitate drain
down in winter period.
5. The condensate drain at e base of e unit collects e
condensation from e evaporator fins.This should be run away to
waste via 1½" domestic waste piping. It is erefore necessary to
ensure at e Calorex Heat Pump is placed on a level plin so
at e condensate later can run away and not overflow e edges
of e drip-tray inside e machine.
6. When e pipework installation is complete e pool pump should
be switched on and e system tested for leaks. Also check
e filter gauge to see at ere is not an excessive increase in
back pressure. If everying is en working normally e water
circulating system is ready to use.
7. Water circuit to and from unit to be capable of maintaining wiin
specified limits e rate of flow required by heat pump (see data
sheet).
8. All pipework must be adequately supported wi allowance for
expansion/contraction especially wi plastic pipework.
9. It is recommended at when installing water system e last
connections to be made in e system should be e breakable
couplings to avoid any stresses on to e unit connections.
