Figure 4: Restrictions on installation with the space between the tank unit and the
heat pump unit
Total piping length:
15 metres maximum per way
Number of bends: 6 maximum
Caution
Keep the piping run to a minimum
as the longer the pipe run the
greater the potential for heat loss
.

Power requirement
The power requirement for the system is a dedicated 20 amp circuit fitted with a
circuit breaker. This circuit may be connected to continuous or OFF peak power
and licensed installer. Installation of this system must be carried out only by a
qualified installation technician (electrical and plumbing).
The surface to which the heat pump unit is installed must be firm, preferably a
concrete pad or block. If the surface is firm there is no need to fix the unit to a base
surface, unless there is a likelihood of high wind or local vibration. If the heat pump
unit and tank unit are fixed, appropriate fixing devices should be used.
A pressure and temperature relief (PTR) valve is included in the installation kit of
the tank unit. This is installed in a defined point near the top of the tank unit. The
PTR valve must have a clear space where escaping steam or water can flow freely
(as per AS/NZS3500 plumbing code).
The installation site must be well drained so that any water accumulating (such as
local rain or pipe leakage) will drain away and not enter the heat pump unit and the
tank unit.
Local water pressure must be a minimum of 200 kPa to ensure efficient functioning.
Note: The entire system is set up and fully functional when supplied. Once all the water
and electric connections have been made the system finds the right timing to run
the water heating cycle automatically as long as the electricity is available. The only
adjustment required is the current time setting on the timer setting panel under the
top housing cover, especially if the block out time setting is desired. See current
time setting and block out time section on page 16.
