PPT16/22 BHC & PPT16BMCY OWNER INSTALLATION MANUAL

Calorex ‘Propac’ HC air to water heat pumps are for areas of e world where

e ambient temperature can vary from 7ºC to 50ºC. The pool water is

heated when e ambient temperature is low and cooled when e ambient

temperature is high, enabling e user to enjoy e pool roughout e year.

The units are designed for swimming pools, using R134a as a refrigerant and

are ideally suited for operation in a tough climate.

Calorex ‘Propac’ BMC air to water heat pump is designed to operate in

temperatures from -15ºC to 40ºC and is suitable for heating and chilling

swimming pools.

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. PPT8/12 heat pumps are ﬁtted

wi rotary compressors and PPT16/22 heat pumps are ﬁtted wi scroll

compressors. Bo types of compressor are known for quiet running.

A 6 minute compressor start delay timer is incorporated for compressor

protection. Wi ese features e heat pump is designed to have a long,

trouble free life.

All units have integral safety devices to protect e heat pump from internal

and external faults. Indicator lamps indicate operating mode. An adjustable

digital ermostat controls water temperature.

Danerm Ltd is an ISO9001:2000 certiﬁed company.

All Calorex heat pumps are CE approved

1.1 FUNCTION

The Calorex Swimming pool heat pump 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.

COEFFICIENT 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

4kW of energy from e air, and delivering 5kW of heat to e pool 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 swimming pool heat pumps, 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 e pool water.

The heat is given up to e cooler pool 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-

1. THE COMPRESSOR where it is

compressed and upgraded to a much

higher temperature. The hot vapour now

enters-

4. THE EXPANSION DEVICE and from ere, now at

normal pressure, it is returned to e evaporator and

e cycle starts again.

2.0 INSTALLATION

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.

2.1 ACCESSORIES

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).

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 50mm female connectors - On delivery e heat pump has 1½” sockets

attached to e water connections for ﬁtting 1 ½” plastic pipes. If 50mm

pipework is preferred undo e readed couplings on e water in/out

connection points and carefully remove e 1 ½” sockets. Then ﬁt e 50mm

sockets in eir place and reﬁt e readed couplings. The heat pump can en

be ﬁtted wi 50mm plastic pipe.

2 x Condensate drain piece - Condensate drain pieces are supplied suitable for

¾” 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.

SD6381652 ISSUE 4

2.3 AIR FLOW

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.

Table 1

Model Minimum Free Area m2

Inlet Discharge

PPT16 0.322 0.173

PPT22 0.322 0.173

Due consideration must be given to air ﬂow i.e. do not obstruct inlet or outlet

and ensure 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 rough a wall etc.

Free areas is e available area rough which air can pass rough a grille or

louvres.

3.0 PLUMBING

a) Calorex Heat Pumps have water inlet/outlet connections as follows:

All models have ﬁttings which enable e heat pump to be connected to eier

1½” or 50mm pipe work.

b) The heat pump is supplied wi bungs ﬁtted in e water connection ﬁttings

These need to be removed before e heat pump is installed. (See section

3.2).

c) The Calorex 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 Heat

Pump should be connected between e ﬁlter and e oer heater. (See

section 3.1).

d) Suitable breakable couplings should be installed local to e heat pump.

e) If e heat pump is installed at a lower level an e pool en isolation

valves should be ﬁtted.

f) A drain valve or plug should be ﬁtted to e lower pipe to facilitate drain

down in e winter period.

g) Connections on all models are by 1½” or 50mm Female ﬁttings. The water

in/water out pipes need to be glued into ese connections using a

suitable adhesive.

h) The condensate drain at e base of e unit collects condensation from e

evaporator ﬁns. This should run away to waste via ¾” domestic waste

piping. It is erefore necessary to ensure at e Calorex Heat Pump is

placed on a level plin so at e condensate water can run away wi

adequate fall to waste i.e. ½” per foot minimum and must incorporate a “u”

trap as to not overﬂow e edges of e drip tray inside e heat pump.

See below.

) 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 for use.

j) Water circuit to and from e unit is to be capable of maintaining wiin

speciﬁed limits e rate of ﬂow required by e heat pump. (See section 9).

k) All pipework must be adequately supported wi allowance expansion/

contraction especially wi plastic pipework.

l) It is recommended at when installing water systems e last connections

to be made in e system should be breakable connections to avoid any

stresses on e unit connections.

IMPORTANT

1. All Pool Purifying Devices and Chemical Injection Systems to be ﬁtted down

stream of e heat pump (see section 3.1) unless installation is as per ﬁlter

dosing. This includes e practice of dosing chemicals direct into skimmer

basket, which results in concentrated corrosive liquids passing over

vulnerable metal components.

2. Water quality must be maintained as follows:

3. Maximum pressure of water in heat pump circuit should not exceed 3.5bar

for PPT16/22 (50 psi).
