INSTALLATION
HEAT PUMP INSTALLATION
. Installation must be simple and allow easy access for
later work.
. If the unit is to be installed on a floor, its
undercarriage should be heightened to avoid
ingestion of accumulated water. The recommended
height is 20cm to 30cm. In snowy areas it is
important to prevent accumulated snow from
blocking up the air outlet.
. A drain or other facilities should be arranged under
the outdoor unit, to avoid environment influence due
to water discharge.
. If the unit is installed on a balcony or on a rooftop,
the installation site must meet the allowable bearing
capacity of building structure without affecting the
structural safety.
. Ensure the unit is well ventilated with the direction
of the air exhaust is kept away from windows of
neighbouring buildings and the exhaust air cannot
flow back. Moreover adequate service clearance
should be kept around the unit.
. The unit should not be installed at places near oil,
flammable gas, or corrosive components.
. The unit must be installed on reliable base or
framework. Weight capacity of framework should be
3 times of the body weight, and safeguard measures
should be taken to avoid malfunction of fastenings.
. The unit should not be installed at sites with typhoon/
earthquake hazards. Mid-air installation should be
avoided as much as possible as machine falling down
may result in terrible accident.
. Do not install the heat pump close to a road or path
to avoid water splashing on the unit. If possible,
position the heat pump away from areas easily
accessible to children.

WATER SYSTEM INSTALLATION
WATER TANK INSTALLATION
. The water tank should be put in a place where
ambient temperature is high.
. It can be installed either outdoors or on a roof-top
(some elements such as the size of water tank and
the bearing capability of the building should be
considered). Installation on a roof-top should have
support such as crossbeam or pillar.
. The water tank should not be installed lower than the
foundation of the heat pump. It is suggested to install
the heat pump, the water tank and the circulation
pump at the same level. The height difference
between the heat pump and the water tank should
be no more than 2 meters, when water tank position
is higher than that of the heat pump.
. Do not install the water tank in a polluted or corrosive
environment.
WATER PIPING INSTALLATION
. The drainpipe and overflow pipe should be installed
near a gutter or sinkhole for draining water eciently.
A discharge valve is necessary on the drainpipe.
. A service valve needs to be installed before the
magnet-valves on the system pipeline for further
inspection.
. The pressure of the water outlet should be between
0.3MPa and 0.6MPa.
. It is recommended to use metal pipeline such as
stainless steel pipes, internal-plastic pipes, internal
stainless steel pipes or copper pipes. Telescopic
issues of the pipeline between heat pump unit and
water tank should be considered if plastic pipeline
such as PPR pipe and ABS pipe is used.
. In winter heat preservation may need to be carried
out for the water supply valve and the stop valve of
the system (according to local ambient temperature)
to avoid icing of the water supply pipe and the valves.
. Keep the water pipes straight and the pipeline
allocation reasonable. Reduce pipe turnings as much
as possible to reduce water resistance.
. Prevent the pipeline and the connectors from water
leakage.
. The water pressure bearing capability of each part
of the piping system should be tested after the
installation is finished. Drainage should be done to
create a clean interior system.
. Measures of heat preservation for the hot water
pipeline needs to be conducted after assuring no
water leakage.
