Pre-Installation
Important Site Instructions
The installation, commissioning, inspection, maintenance and repairs must only be carried out by
a qualified person.
All electrical wiring must be completed by a licensed electrical contractor in accordance with the
appropriate standards.
The drilling work requires a permit from your local council.
The heating system and heat source must be properly designed and dimensioned to ensure an
efficient operation. It is particularly important to keep water flow temperatures as low as possible.
The minimum heating water flow rate through the heat pump must be assured in all operating
states of the heating system.
Movement and storage
The unit must not be transported, moved or stored at greater than a 30° angle from the upright
position. Install and store the unit in a dry area. They are not rated for outdoor use.
Safety
If a refrigerant leak occurs, remove the complete charge using a recovery unit and store the
refrigerant in mobile container.
Note: care is to be taken as the refrigerant can breakdown due to high temperature, these
refrigerants by-products are dangerous.
Once the leak has been repaired recharge the unit with the correct filling weight and the type
found on the unit’s nameplate.
Note: ensure the correct refrigerant gas is used to recharge the unit as an incorrect gas can cause
damage beyond repair to the compressor.
Do not use oxygen to purge lines or to pressurize a unit for any purpose.
Oxygen gas reacts violently with oil, grease and other common substances.
Use only refrigerant or dry nitrogen for testing.
Never exceed the specified maximum operating pressures.
Do not un-weld or flame cut the refrigerant lines including any refrigerant circuit components
until the entire refrigerant (liquid and vapour) has been removed from unit. Traces of vapour
should be displaced with dry nitrogen.
Refrigerant in contact with an open flame will produces toxic gases.
Ensure that the necessary safety protection equipment is available when servicing. Have the
appropriate fire extinguishers for that system.
Do not siphon refrigerant.
Avoid spilling liquid refrigerant onto the skin or splashing it into the eyes. Use safety goggles.
Wash any spills from the skin with soap and water. If liquid refrigerant enters the eyes,
immediately and abundantly flush the eyes with water and consult medical advice.
Note: Never apply an open flame or live stream to a refrigerant container. This can dangerously
overpressure and cause an explosion.
