AWA-SS series consists of a heat pump, water heater,
electrical module, circulation pumps and a control sys-
tem. AWA-SS series is connected to the Outdoor Unit
and heating medium circuits.
The heat source of the AWA-SS series is provided from
air. the Outdoor Unit of the system is a heat exchanger
for collecting the heat of air.
The air emits its heat to the refrigerant in the evapo-
rate of Outdoorunit. It then vaporises and is com-
pressed in the compressor. The refrigerant, the tem-
perature of which has now been raised, is passed to
the condenser where it gives off its energy to the heat-
ing medium circuit and, if necessary, to the water
heater. After the condenser there is a built-in electrical
module which cuts in if there is a high demand.

General information for the installer
7
Current regulations require the heating installation to
be inspected before it is commissioned. The inspec-
tion must be carried out by a suitably qualified person
and should be documented. The above applies to
closed heating systems. If the heat pump is replaced,
the installation must be inspected again.
AWA-SS series is placed on a firm base, preferably a
concrete floor or foundation. Install AWA-SS series
with its back to an outside wall, ideally in a room where
noise does not matter. If this is not possible, avoid
placing it against a wall behind a bedroom or other
room where noise may be a problem. Any wall that
backs on to a bedroom should be fitted with sound
insulation. Route pipes so they are not fixed to an inter-
nal wall that backs on to a bedroom or living room.

The AWA-SS series must be transported and stored
upright and dry. The AWA-SS series may however be
carefully laid on its back when being moved into
a building.
Transport and storage
2) There is no need to charge extra refrigerant into the
copper pipe while its length is less than 5 meters.
3) While the copper length is more than 5 meters,
copper pipe while its length is less than 5 meters.every
extra 10g refrigerant must be charged for per increased
1 meter length.
Pipe connections
8
Pipe installation must be carried out in accordance
with current norms and directives. The heat pump can
operate up to a return temperature of about 58* °C
and an outgoing temperature of about 70* °C from the
heat pump. The compressor produces up to 65* °C,
the rest is obtained using additional heating.
The other heat pumps has a max return temperature
of approximately 50 °C and an outgoing max tempera-
ture from the heat pump of approximately 60 °C.
Since the AWA,AWB series is not fitted with shut-off
valves, these must be fitted outside of the heat pump
to make future servicing easier.
During assembly the pipes for the heat medium
and water heater and possibly hot water circulation
are routed backwards. The distance between
AWA-SS series and the wall ought to be 50 mm.
General
NOTE!
The pipe system needs to be flushed
out before the heat pump is connected
so that debris cannot damage
component parts.
The size of the outlet for connecting copper pipe can be
adjusted by the fixing board.
Copper pipe connections
According to their practical situation,users can choose
the place on mainframe ( left or right ) for the out
of connecting copper pipe.
NOTE!
defrosting temperature sensor and outside
temperature sensor should be connected

Pipe connections
9
Pipe connections for the heat medium side are made
at the top. All required safety devices, shut-off valves
(as close to the heat pump as possible), and particle
filter (supplied) are fitted.
When connecting to a system with thermostats on all
radiators, a relief valve must be fitted, or some of the
thermostats must be removed to ensure sufficient
flow.
Pipe connections (heating
medium) The heat pump´s water heater must be fitted with the
necessary valve equipment.
Pipe connections (water heater)
The heat pump should be supplemented with an elec-
tric water heater if a bubble pool or other significant
consumer of hot water is installed. The valve coupling
in COMPACT (electrical water heater) can be divided.
The mixing valve stays in COMPACT and the remain-
ing valve coupling can be used for incoming cold
water in AWA-SS series.

How to connect the copper pipes
Piping Connecton
Attention :
When connectiong the pipe, a suitable pitching spanner must be used. If other spanner is used, it may
damage the joint due to inappropriate force.
4. Connect the electric cable as per circuit diagram, and bundle
it with the connecting pipe.
1. Open the cover of the outdoor unit.
2. Connect the pipe to the indoor unit and outdoor unit.
Align the centre of the pipe and fully screw in the angular nuts with Finger.
On connecting the pipe, one should ensure that the insulating material of the pipe be closely fitted to
the nuts at the joint.
On connecting to the external unit, the pipe should be wrapped with sponge padding to prevent
rain water from flowing in.
When bending the pipe, the radius cannot be too small and be about 150~160 mm.

3. Use Vacuum pump to remove the air from indoor unit and
connection pipe.
Wipe the quick connectors with clean cloth to prohibit dust and impurity entering the pipes.
5. Take off the nuts in the mouths of high valve and low valve, turn
the valves core anticlockwise with hexagon panner till the valves
are opened completely. Recover and tighten the nuts.
6. Check leakage: check if there is leakage at each connection of the
pipes or nuts. If yes, remedial neasure must be taken, leakage is
not permitted in any case.

4. Tighten the cap of two valves.
5. Disconnect the power cable from outdoor unit.
6. Loose the nut of the connect pipe to the outdoor unit valve with 2 spanner, disconnect the connect pipe
and the two valves.
1. Start the machine, operate heat pump on state.
2. Remove the cap of two valves with the spanner.
3. Tighten the core of the liquid valve (the smaller one) with valve key at first . After about 20 seconds, tighten
the core of the gas (the bigger one) with valve key. Turn off the machine at once and cut off the power supply.
If the outdoor unit needs to be disconnected and moved to another place, please recycle the
gas back into the compressor according to the following steps before doing the disconnecting:
