General information
The heat pump MUST be installed free-standing on a level and stable base capable of
withstanding the weight of a full system.
Where property damage can occur as a result of water leakage, the system MUST be installed with
a safe tray (overflow tray) and drain in accordance with AS/NZS 3500.4.
Unit orientation
The heat pump is designed for open air
operation, requiring sufficient air supply to
maintain operating efficiency. The air inlet and
outlet of the heat pump must be positioned
away from prevailing winds, and be provided
with sufficient clearances as shown in the
installation guide.
Genuine Rinnai parts
Only use the included accessories, and
specified parts for installation. Using non-
standard parts can cause water leaks, electrical
shock, fire, and cause the unit to fail.
Defrost function and freeze protection
The unit will go into defrost when the evaporator
temperature sensor reads temperatures below
-5 °C for over one minute. This sensor signals
the PCB in the unit to start the compressor
which will discharge hot gas into the evaporator
coil to gently melt the ice. The fan and pump will
also run to accelerate the defrost function.
Defrost will stop once either of the below
conditions are met:
•
Defrost reaches 15 minutes
•
Evaporator temperature sensor reads a
temperature ≥ 5 °C
If you live in an area prone to frost and will be
away for an extended period with the power
supply disconnected, Rinnai recommend
draining your system, by an authorised
tradesperson, to prevent frost damage. Frost
damage which is not covered by warranty.
Snow zone locations
If the location is prone to snow the system must
be in a covered location. The system will not
operate if snow is allowed to build up on top of
the appliance.
We do not recommend switching the system off (without power connected) in areas
where frost could occur or in the middle of winter. Damage to the system if not continually
NOTE
connected to the electricity supply is not covered by warranty.

Disposal guidelines
This system contains refrigerant and other
potentially hazardous materials. Do not dispose
of this system as household waste. Contact
Rinnai for more information.
Electrical connection
The heat pump is fitted with a power cord
and 15 A plug. It must be connected to an
independent, fused AC 230 V 50 Hz power
supply with an isolating switch installed at the
switch board.
All electrical work and permanent wiring
must be carried out by a qualified person in
accordance with AS/NZS 3000 Wiring Rules.
Note about water / water blasting
The Enviroflo has an IP24 rating which
means it's protected against splashing water,
for example rain. It is not protected from
sustained low or high pressure water, for
example water blasting.
Power supply disruption
If the power goes off the system will retain all of
its settings, including the day and time. When
power is restored the system will come back
on, approximately two minutes afterwards, in
the operation mode that was previously set.
The slight delay in operation is a safety feature
designed to protect the compressor.
Condensation
During normal operation condensation occurs
in the heat pump as air across the evaporator
is cooled. In high humidity locations a large
volume of condensate can be generated. The
installer will ensure condensate is plumbed to a
suitable drain.
