15.2 Condensate lines
Large amounts of condensation water, as well as melt water from defrosting
cycle can be produced. Provide good drainage at the installation area and
make sure water cannot run out onto paths or the like during periods that ice
can form. Ideally condensation water is led off to a drain or similar. The
condensation water pipe must have a minimum diameter of 50 mm and
should be discharged to the sewer drain in a frost-proof location
15.3 Water loop connection
Please pay attention to below matters when the water pipe is connected:

Keep pipe work as free from bends as possible to keep back pressure in
the system to a minimum. Make sure that fittings, manifolds, water
pumps and valves in the system are designed for full flow as restrictions
in the system from these can materially and adversely impact upon the
performance of the unit and effectiveness of the overall heating system.

The piping must be clear and free from dirty and blocks. Water leakage
test must be carried out to ensure there is no water leaking. And then the
insulation can be made.

There must be expansion tank on the top point of the water loop, and the
water level in the tank must be at least 0.5 meter higher than the top point
of the water loop.

The flow switch is installed inside of the heat pump, check to ensure that
the wiring and action of the switch is normal and controlled by the
controller.

The connection between the heat pump and the construction is better to
be flexible type, to avoid vibration transfer. The support to the water pipe
must be separate, but not rely on the heat pump unit.

There must be thermometer and pressure meter at the water inlet and
outlet, for easy inspection during running.

There must be drainage on the low points of the water system, and there
is already drainage on the chassis of the heat pump. The water in the
system must be drain out during winter. if the heat pump is not running.
And there must be air vent on the high point of the water system to drive
air of the water. Drainage and air vent need not to be insulated, in order
to maintain.
ATTENTION
The hydraulic connection should be installed according to the local legal
laws and regulations as well as the qualified professional.
