Precautions - Rheem RTHP009 Installation Maintenance And Service Manual

By contrast, in warmer months the heat pump will run less hours than the filter. The heat pump may
be left ON, (i.e. with power supply), as it will only run if the pool temperature falls below the desired
set point by -0.5C.
Where the Heat Pump is installed on a separate heating circuit (i.e. separate recirculating pump),
the ideal scenario is that a control logic/interface is in place between the heat pump and the
recirculating pump. That is, flow is provided only when heating is required so that the pump use is
limited strictly to those hours needed to maintain the pool temperature.
The Rheem Thermal heat pump may be provided with pump-call or a pump control function so that
a run signal is provided to the pump via the heat pump's controller based on temperature signals.

PRECAUTIONS

Where damage to property can occur in the event of the heat pump leaking, the unit must be
installed in a drained drip tray in accordance with AS/NZS3500.4 and local codes and
regulatory authority requirements.
The heat pump must be maintained in accordance with the Owners Guide and Installation
Instructions.
If the heat pump is to be used in a commercial application, you should ensure that you have
adequate redundancy within the heating system. This should ensure the continuity of heating
in the event that the heat pump should become inoperable for any reason. We recommend
that you seek advice from your Rheem Thermal representative or your specifier about your
needs and building redundancy into your heating system.
In operating your heat pump, you should ensure that the hydraulic layout of the system is
correct. Particular care should be given to ensure that excess pressure is not created to the
heat pump's internal heat exchanger(s).
