PR0-PAC SYSTEM OWNER INSTALLATION MANUAL

3. PLUMBING

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 should be connected between the filter and the other 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 than pool water then isolation valves
should be fitted.
4.
Drain valve or plug should be fitted to lower pipe to facilitate drain down
in winter period.
5.
The condensation from the evaporator fins drains away through holes in
the base of the unit. If desired, an optional factory fitted driptray with 1½"
sink fitting can be fitted to allow the condensate to drain via 1½" domestic
waste piping. In this case it is necessary to ensure that the Calorex Heat
Pump is placed on a level plinth so that the condensate can run away
with adequate fall to waste ie ½" per foot minimum. A U trap should also
be incorporated into the pipework.

6.
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.
7.
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).

All pipework must be adequately supported with allowance for
expansion/contraction especially with plastic pipework.
9.
It is recommended that when installing water system the last connections
to be made in the system should be the breakable couplings to avoid any
stresses on to the unit connections.
