Installation
1. The pipe installation must adhere to the local
Building Code, standards and any local council
requirements.
2. Ensure that the water flow and returns are correct and
not reversed. Reversing the water flow will reduce
the output of the unit; refer to the labels on the unit
for the correct water flow direction.
3. The water pipes must not transmit any radial or
axial forces to the heat exchanger. Allow some pipe
flexibly between the unit and the structure to reduce
any stresses and vibrations issues.
4. The water supplied to the system must be clean and
not contain heavy metals that could cause harm
to the unit. The water must be treated with an
approved inhibitor and tested annually to prevent
corrosion, fouling and deterioration of the pump
fittings.
5. Protection devices are to be installed to protect the
unit from operating outside of its running parameter
such as control devices; shutoff valve, bleed valves,
safety valves and expansion tanks.
6. The pipe installation should be designed to have the
least number of elbows and joiners as they reduce
flow. Install drain connections at low points to allow
the system to be drain if required.
7. Flexible connections should be used where possible
to reduce vibration transmission.
8. Insulate all pipe work and exposed areas to protect
against both thermal heat loss and to prevent
condensation on chilled pipes.
9. When filling the water system, use air vents and
flushing procedure to evacuate any residual air
pockets.
10. The heat pump is not fitted with shutoff valves and
therefore these must be fitted outside of the heat
pump to facilitate future service requirement.
