WINTERISING/START UP
If the heat pump is being left for a short period of time AND has
adequate frost protection, i.e. frost protection stat and/or
antifreeze, the heat pump can be left in the same way as you
would leave a conventional central heating boiler.
If the heat pump is to be shut down over the winter period
follow the Winterising Procedure below.
WINTERISING PROCEDURE
WARNING. Isolate machine before entering! As the heat pump
embodies electrical and rotational equipment, it is
recommended for your own safety that a competent person
carries out the following procedure.
(Drain Down Procedure)
ALL MODELS
Object
To provide frost protection
To eliminate corrosion problems
To inhibit electrical components
1. Switch off electric supply to heat pump
2. Remove external fuses and keep in safe place away from
heat pump to prevent accidental operation of heat pump
3. Ensure water circulation pump is switched off.
4. Drain water from heat pump by
a. drain valve if fitted
b. disconnecting pipework to and from heat pump.
Ensure Heat Pump is completely drained.
5. Flush through water circuit in heat pump by using CLEAN
TAP WATER (NOT POOL WATER) via hose into inlet
connection - run for 10 minutes minimum; use spray nozzle
if available.
6. Drain completely - fit plastic bags secured by elastic bands
over water connections.
7. Unhinge electrical enclosure and liberally spray interior of
unit, with moisture-repellent aerosol WD-40 or similar;
reseal enclosure.
8. If heat pump located outside, protect from weather by
covering with VENTILATED cover. Do not use plastic sheet
as condensation can occur within unit.
N.B. If this procedure is not adopted and frost or corrosion
damage results then the warranty will become invalid.
START UP PROCEDURE AFTER WINTERISATION
1. Remove covers (if fitted).
2. Remove front panel - clean air filter and using sort brush
clean finned surfaces of heat pump. Replace panel.
3. Remove plastic covers on water connections and reconnect
water piping or close drain valve.
4. Start up water circulating pump and leave running for at
least 1/4 hour to establish flow and enable any air in piping
to escape.

LOSS OF SYSTEM WATER PRESSURE
The system pressure gauge indicates the central heating
system pressure and that if the normal COLD pressure of the
system is seen to decrease over a period of time then a water
leak is indicated. Re-pressurise the system, if unable to re-
pressurise or if the pressure continues to drop a registered
local heating installer should be consulted.
AUTOMATIC DEFROST
Automatic defrosting is a normal part of heat pump operation in
colder weather and normally takes place for about 4 minutes
per hour. When in defrost the mode fan will stop and water
vapour may be seen rising from the heat exchanger. This is
normal and is not a cause for concern.
CONDENSATE DRAIN
Ensure condensate drain is kept free from any blockage/
debris.
SAFETY PRECAUTIONS
1. Minimum clearances - distances to be maintained.
2. Do not stand on the heat pump for any reason.
3. Do not allow children to poke sticks or other objects through
the front grille into the fan as this could cause them harm
and will damage the fan.
4. Outer panels should only be removed by a qualified service
engineer.
CLEANING
The painted surfaces of the Heat pump can be cleaned with
warm soapy water using a soft non abrasive cloth.
Do not use alcohol based cleaners. Diluted washing up liquid
is probably the strongest cleaner that should be used.
The fins of the evaporator should not be allowed to become
clogged as this will affect the performance of the Heat pump.
Having removed the panel covering the evaporator, the fins can
be cleaned with a brush.
SERVICING
No regular servicing of the airtherm 4.5 or 9 heat pumps is
required. However, you are advised to check occasionally that
there is no debris around the heat pump which may get drawn
into or obstruct the heat exchanger. The area around the heat
pump should always be kept clear to avoid obstructing the air
passage through the unit.
The airtherm 12 requires an annual gas leak test to comply
with EU F-Gas regulations. It is the owner's responsibility to
ensure that this test is carried out. Any qualified local
refrigeration engineer should be able to do it for you. However,
if you have encounter any problem, please call the Ideal Service
Department who will be able to help.
