IMPORTANT NOTICE
Danerm Ltd. is an ISO9001:2000 certified company.
All Calorex heat pumps are CE approved.
Heat exchangers wiin e heat pumps are compliant to WRAS
(British Water Regulation Auority Standards) and listed under UL
standards.
The machines described in is manual are specifically designed for
heating potable water. The heat pumps use R134a as a refrigerant and
operate in air temperatures from 7ºC to 50ºC providing heated water to
68ºC.
As an option AW3034 and AW7034 machines are available wi reverse
cycle defrost which allows e heat pumps to operate in temperatures
down to -15ºC.
All units are supplied as a package and have integral safety devices
to protect e heat pump from internal and external faults. Indicator
lamps indicate operating mode. An adjustable ermostat controls water
temperature. Also a 6 minute cycle time delay is incorporated. The units
are weaerproof and can be installed eier outside or wiin a ventilated
plantroom (as detailed in section 1 of is manual).
A 12 hour delay timer is incorporated into 3034 and 7034 machines,
which aer a power interruption or from initial start up will prevent e
machine compressor(s) from starting for a 12 hour period. This feature is
to protect e compressors from liquid pumping which can cause internal
compressor damage.

The CALOREX Heat Pump provides ermodynamic heating by means
of a vapour compression cycle, (similar to at employed in a conventional
refrigerator), in addition to operating as an active solar collector.
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.
Naturally is ratio will vary according to e temperature of e ambient air.

4. The EXPANSION DEVICE and from ere,
now at normal pressure, it is returned to e

1. The EVAPORATOR collects e heat from e outside ambient
air, pre-heated by e sun. High volumes of outside air are drawn
rough e Calorex unit by e fan and 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
vaporizes. This preheated vapour now travels to -
3. The CONDENSER where it is surrounded by e water
to be heated. The heat is given up to e cooler water and
e now cold refrigerant returns to its former liquid state
but still under high pressure from e compressor. This
pressure is released by passing e liquid rough -

SD331851 ISSUE 28

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.
c Protect unit if installation is delayed.
d Provide a firm level base capable of supporting operational weight of unit;
spread load on timber floor.
e Ensure water cannot collect under unit - recommend units are installed on
plins 100mm above finished floor level and to also aid condensate drainage.
f Allow adequate clearance to service panels on unit; recommend 500mm
minimum (see installation drawings).
g All Calorex heat pumps are by design as quiet as is practical, however due
consideration should be given to siting in order to fully exploit is feature, i.e.
orientate inlet/outlet parallel to occupied premises.
h Ensure loose debris such as leaves, grass cuttings, etc will not block air inlet
grilles.
i 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, i.e. do not obstruct inlet or outlet
and ensure discharge air cannot recirculate to inlet. (See figures 1 and 2)
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 area is e available area rough which air can pass rough a grille or
louvres.
1. Note: 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. If e unit is installed wiin a plantroom, connected to ductwork, Danerm
Ltd. can supply e unit wi an uprated fan motor.
Please consult Danerm Ltd. before ordering a unit.

AW834,1234AH/BH,1534BH AW 3034,7034H/HY OWNER INSTALLATION MANUAL

a Calorex ‘34’ range Heat Pumps have water inlet/outlet connections as
follows:
AW834/1234/1534 models ¾ “ BSP parallel, male.(wi ¾” BSPF x 1½” ABS
male adaptors supplied loose).
AW3034/7034 1 ½” BSP parallel, male.
The machine is supplied wi bungs fitted in e water connection fittings.
These need to be removed before e unit is installed.
b If an existing heater is being retained, e Calorex Heat Pump should be
connected before e existing heater.
c Suitable breakable couplings should be installed local to heat pump.
d If heat pump is installed at lower level an e water en isolation valves
should be fitted.
e Drain valve or plug should be fitted to lower pipe to facilitate drain down in
winter period.
f Connections on all models are by parallel female fittings sealed by silicone
mastic ese should be hand tightened only, oerwise damage may result to
e reads of plastic fittings.
g The condensate drain at e base of e unit collects e condensation from
e evaporator fins. On 834-1534 models his should be run away to waste via
¾” domestic waste piping using connector supplied. On 3034/7034 models
e waste piping needs to be 1 ½”. It is erefore necessary to ensure at e
Calorex unit is placed on a level plin so at e condensate water can run
away wi adequate fall to waste i.e.½” per foot min and must incorporate a ‘u’
trap as to not overflow e edges of e drip-tray inside e machine.
h When e pipework installation is complete e pump should be switched
on and e system tested for leaks. If everying is en working normally e
water circulating system is ready to use.
i 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).
j All pipework must be adequately supported wi allowance for expansion/
contraction especially wi plastic pipework.
k It is recommended at when installing water systems e last connections to
be made in e system should be e breakable couplings to avoid any stresses
on to e unit connections.

DETERMINING WATER FLOW AW3034/7034H
a Flow Meter Meod (see fig 3).
Ensure isolation valves ‘A’ and ‘B’ and bypass valve ‘C’ are fully open. Slowly
close down bypass valve ‘C’ until correct flow rate is shown on e flow meter.
(see data sheets pages 28 to 30) Remove handle and lock off valve ‘C’.
b Differential Pressure Meod (See fig 3).
By simply installing two filter pressure indicating gauges, one each on e
inlet and outlet of e heat pump, and a locking type gate bypass valve
in e bypass line, e flow rate rough e heat pump can be accurately
determined by e difference in e readings of e gauges.This pressure drop is
proportional to flow.
Flow rate should be set at e maximum differential.
Setting up e differential.
When e installation is complete, e procedure for setting e flow rate
rough e heat pump using two gauges is as follows:
1. Wi e heat pump switched off, ensure isolation valves ‘A’, ‘B’ and bypass
valve ‘C’ are fully open.
2. Switch on water circulating pump.
3. Note e water System Pressure on bo gauges - ey should read e
same, but because of manufacturing tolerances ey may have different
readings.
For example; wi a water system pressure of 5mhd e gauge on e inlet
may read 5 and e outlet gauge 5·5 erefore ere is a STATIC ERROR
DIFFERENCE of 0·5mhd.
4. Gradually close e bypass valve ‘C’ until ere is a difference in pressure
between e two gauges at is equal to e required pressure drop (see data
sheet) observing any static error on e gauges before beginning is process.
5. Lock e bypass valve, or render it tamper proof, when correct setting is
achieved.
6. See data sheets pages 28 to 30 for correct water pressure drop.
