SECTION 2: HEAT PUMP INSTALLATION
Clear space clearance around outdoor unit.
• Locate the heat pump away from combustible material
• Inlet - 200mm clear air
• Outlet - 1000mm clear air
INSTALLATIONS REQUIRING EXTENSION LINES
Standard unit has 2 mtrs of refrigerant line connected to the Heat Pump unit. Considering bends and connections, this allows
the Heat Pump unit and Water Tank to be installed to a distance apart as shown (Drwg A). (This is intended as a guide only.)
Many installations will require the Heat Pump outdoor unit and the Water Tank to be positioned further apart than the
standard unit configuration allows. In these installations, an extension line kit needs to be used.

These extension line kits come fully insulated, pre-charged and include the longer thermostat cable e.g. a 300SSBX has a
6 mtr thermostat cable to replace the standard 3 mtr Thermostat cable (1 metre longer than the refrigerant lines).

The maximum length of refrigerant line to be connected to the Heat Pump is

metres.
E.g. 2 metre standard
+
7 metre extension = total 9 metres max.

REFRIGERANT LINES IN DUCTS,
WALLS OR SURFACE MOUNTED
In most installations the refrigerant lines
will be surface mounted. They should
always be protected in PVC surface
trunking designed specifically for air
conditioning systems.
If the refrigerant lines are to be installed
in a wall cavity or through timber
framing they need to be installed by
notching the timber. It is not possible to
fit the line couplers through a hole less
than 90mm diameter.
R
efrigerant lines run underground must
be enclosed in a 100mm PVC pipe. An
extension kit should be used and run
through the pipes prior to Installation.
