3.3 Pipe Connection
28mm pipe is recommended.
The pipe work must be flushed before the heat pump is connected, so that any contaminants do
not damage the components parts.
The heating/cooling water inlet and outlet direction must be connected according to the marked
areas on the heat pump.
All outdoor pipes must be thermally insulated with at least 19 mm thick pipe insulation. The
insulation must also be vapor resistant.
The water circulation pump must at all times be operational (even if unit is not running) to prevent
any possible damage due to freezing. Even when in standby mode, the circulation pump is
controlled directly from the unit, which takes the outdoor temperature and temperature in pipe into
consideration to decide whether to circulate water within the system.
Shut-off valves and drain valves are fitted so that unit can be emptied in the event of prolonged
power failures.
The supplied flexible hoses act as vibration dampers. The flexible hoses are fitted so a slight bend
is created, thus acting as vibration dampening.
Important:
Even though the unit has anti-freeze protection, if the circulation pump fails or there is
a problem with the power supply, there is still a risk of damage due to freezing.
During the
installation Anti-freeze (Ethylene Glycol) is strongly recommended. If the air
temp is ever lower than 0c, it must use enough glycol.
