The Compac range of air/water heat pump is designed for swimming pool
heating. The heat pumps are designed to heat pool water and spas within
the range of 15°C to 35°C, suitable for outdoor pools operating in ambient
temperatures above 5ºC.
The water heat exchanger is a full flow type, manufactured from titanium
tube, which is a highly corrosion resistant material. The heat pumps are
suitable for use in fresh water and salt water pools.
The heat pumps are fitted with rotary compressors known for quiet running.
A 3 minute cycle time delay is incorporated for compressor protection. With
these features the heat pump is designed to have a long, trouble free life.
All units have integral safety devices to protect the heat pump from internal
and external faults. Indicator lamps indicate operating mode. An adjustable
digital thermostat controlsthe water temperature.
1.0 Introduction

Installation Manual Compac 6/8
1.1 Function Swimming pool heat pumps provide thermodynamic heating by means of a
vapour compression cycle, (similar to that employed in a conventional
refrigerator), in addition to acting as an active solar collector.
Coefficient of Performance
The efficiency of a Heat Pump is usually called its ‘Coefficient of Performance’ - (C.O.P.)
which is simply a ratio of heat output to energy input, both being expressed in kW. Thus a
Heat Pump absorbing 1 kW of electricity, collecting 4 kW of energy from the air, and
delivering 5 kW of heat to the pool water is said to have a C.O.P. of 5:1.
This ratio will vary according to the temperature of the water and the ambient air.

1. THE EVAPORATOR collects the heat from the
outside ambient air, pre-heated by the sun. In the
swimming pool heat pumps, high volumes of outside
air are drawn into the unit by the fan and expelled
through the evaporator fins. The evaporator has liquid
refrigerant passing through it, which is at a
considerably lower temperature than the ambient air,
therefore the air gives up its heat to the refrigerant
which then vaporises.This preheated vapour now
travels to -
2. THE COMPRESSOR
where it is compressed
and upgraded to a much
higher temperature. The
hot vapour now enters -
3. THE CONDENSER where it is surrounded by the pool
water. The heat is given up to the cooler pool water and
the now cooler refrigerant returns to its former liquid
state but still under high pressure from the
compressor.
This pressure is released by passing the liquid through
-
4. THE EXPANSION DEVICE
and from there, now at normal
pressure, it is returned to the
evaporator and the cycle
starts again.

a) Ensure that the heat pump on site is as ordered, i.e. model, electrical
supply and factory fitted options.
b) Inspect the unit for damage, in particular inspect the evaporator (finned
side) to ensure that it is undamaged. (Minor indentations in the fins do not
affect performance). If severely damaged, endorse the delivery note in the
presence of the driver and send a recorded delivery letter to the transport
company giving details.
c) Protect the unit if installation is delayed.
a) Provide a firm level base capable of supporting the weight of the unit;
spread the load if mounted on timber floor.
b) Ensure that water cannot collect under the unit, it is recommended that
units are installed on plinths 100mm above finished floor level. This also aids
condensate drainage.
c) Please allow adequate clearance to service panels on the unit;
recommended 500mm minimum.
d) The 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 effect of noise coming from the machine, for example by positioning the
machine so that the inlet/outlets are parallel to occupied premises.
e) Ensure loose debris such as leaves, grass cuttings, etc will not block air
inlet grilles.
f ) Consider protection from extreme weather conditions if installed externally,
i.e. lean-to-cover or building.
g) Use the antivibration feet provided, not only does this help to reduce noise
but it also will help prevent corrosion to the base of the heat pump. Use of
stainless steel fixings is recommended.

IMPORTANT
If multiple units are installed in an enclosed area then the inlet free areas
required for each unit can be added together to form one inlet aperture.
BUT the discharge from each unit must be kept separate and must not be
incorporated into one common duct system.
Due consideration must be given to air flow i.e. do not obstruct either the
inlet or outlet and ensure that the discharge to air cannot recirculate to
inlet. (See below).
Required Free Areas to provide air flow to
and from heat pumps when installed in an
enclosed area or where required to pass air
through a wall etc.
Free area is the available area through which
air can pass through a grille or louvres.
