PP16AMY OWNER INSTALLATION MANUAL

1.0 HOW THE CALOREX ‘PP16AMY’ WORKS.
The Calorex PP16AMY is an air to water heat pump at is designed to provide indirect low pressure hot water (LPHW) to swimming pool air handling units
at contain a water to water heat exchanger. The PP16AMY is an alternative to a fossil fuel boiler and can provide flow temperatures up to 55°C.
The PP16AMY is designed to work in ambient temperatures from-15°C to 35°C.
The PP16AMY is supplied wi an adjustable digital ermostat at controls water temperature and defrosting. For flexible installation e ermostat has a
choice of two positions. Details of how to change e position are shown later in e manual (section 2.4)
Terminals in e PP16AMY can initiate a water pump. These terminals are marked “PUMP RUN”. See section 4.2 for more details
The PP16AMY can be initiated from an external source using e terminals marked “REMOTE ON/OFF INTERLOCK”. See section 4.2 for more details
The PP16AMY is fitted wi a scroll compressor and owlet fan, bo of which is are known for quiet running.
A six minute compressor start delay timer is incorporated to protect e compressor.
The PP16AMY has integral safety devices at protect it from internal and external faults. Indicator lamps indicate e operating mode.

1.1 FUNCTION
The Calorex Indirect heater provides ermodynamic heating by means of
a vapour compression cycle, (similar to at employed in a conventional
refrigerator), in addition to acting as an active solar collector.
Coecient of Performance
The eciency of a Heat Pump is usually called its ‘Coecient of Performance’
- (C.O.P.) which is simply a ratio of heat output to energy input, bo being
expressed in kW. Thus a Heat Pump absorbing 1 kW of electricity, collecting 4
kW of energy from e air, and delivering 5 kW of heat to e water is said to
have a C.O.P. of 5:1.
This ratio will vary according to e temperature of e water and e ambient
air.

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

1.2 FEATURES OF THE CALOREX PP16AMY
• A purpose built Monobloc heat pump designed to provide indirect
low pressure hot water (max 55°C) for swimming pool heating.
• Reverse cycle defrost providing operating capability in air
temperatures as low as -15°C.
• Intuitive PLC control wi digital display of actual and set point
temperatures.
• Visual operating status indication.
• Interlocks for water pump control and remote on/off.
The digital ermostat can be mounted one of two sides of e PP16AMY and
controls and maintains e water temperature and defrosting and incorporates
indicator lamps.

a)Ensure heat pump on site is as ordered, i.e. model, electrical supply and
factory fitted options.
b) Inspect unit for damage, in particular inspect e evaporator (finned side)
to ensure at it is undamaged. (Minor indentations in e fins do not affect
performance). If severely damaged, endorse delivery note in presence of e
driver and send a recorded delivery letter to transport company giving details.
Protect unit if installation is delayed.
The heat pump is supplied wi accessories which aid installation. On delivery
e accessories are in a plastic bag in e heat pump electric box. (See section
4.2 for lid removal).
2.1 ACCESSORIES
These accessories are as follows:
4 x rubber feet - Fit ese under e metal feet of e heat pump to help
reduce e effects of vibration.
2 x Condensate drain piece - Condensate drain pieces are supplied suitable for
3/4” or 20mm pipe. Use whichever piece fits e drain pipe required. Glue e
relevant piece to e driptray outlet and en fit en condensate drain piping.
2.2 SITING
a) Provide a firm level base capable of supporting operational weight of unit;
spread load if mounted on timber floor.
b) Ensure water cannot collect under unit, it is recommend at units are
installed on plins 100mm above finished floor level. This also aids condensate
drainage.
c) Allow adequate clearance to service panels on unit; recommend 500mm
minimum.
d) All Calorex heat pumps are by design as quiet as is practical, however due
consideration should be given to siting e heat pump in order to minimise e
noise coming from e machine, for example by positioning e machine so at
e 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 weaer conditions if installed externally, i.e.
lean-to-cover or building.

Due consideration must be given to air flow when installing e PP16AMY. Do
not be obstruct e inlet or outlet and ensure discharged air cannot recirculate
to e inlet. (See below)
Required free areas to provide airflow to and from heat pumps when installed in
an enclosed area or where required to pass air rough a wall etc.
Free air is e available area rough which air can pass rough a grille or
louvres.

IMPORTANT
If multiple units are installed in an enclosed area en e inlet free areas
required for each unit can be added togeer to form one inlet aperture.
BUT discharge from each unit must be kept separate and must not be
incorporated into one common duct system.

2.4 CHANGING THE POSITION OF THE DIGITAL
THERMOSTAT
On delivery, e digital controller is filled above e water in/out connections.
If is does not suit e installation e digital controller can be moved to e
adjacent panel following e procedure set out below.
1. Isolate e heat pump from e electricity supply.
2. Remove e lid of e heat pump (see section 4.0).
3. Remove e plugs connecting e wiring from e back of e ermostat.
4. Undo e white plastic clips securing e heat pump to e panel. This is
done by pressing e clips in at e sides.
5. Remove e ermostat rough e panel.
6. Remove e dummy ermostat from its position following e same meod
described in point 4.
7. Put e ermostat and dummy ermostat in eir new positions and secure
wi white clips.
8. Re connect e connectors to e ermostat taking care at e red
markers in e plugs and sockets are correctly aligned.
9. Replace e lid and reconnect e heat pump to e electrical supply.
