Quantum 270-11AC3-134 - Manual (Page 16)

Owner’s Manual Quantum Energy Technologies
6d: Service Caution – Before Any Work Is Carried Out
Before any electrical components are inspected the System MUST be turned off at the power
switch / hot water circuit breaker. Do not touch wiring or any electrical components without
supervision or training to Australian (or equivalent) standards.
6e: Thermal Overload (Incorporated in Digital Controller)
All models are fitted with a digital controller for heat pump management. One function of the
digital controller is to initiate a shut down and lockout if the compressor reaches a temperature of
105°C. The system will not automatically restart from this. To reset the system the “SET” button
on the digital controller must be pressed (hold for 6 seconds). Turning the power off then back on
will also perform a reset.
6f: Routine Service
Serving requirements and timing for Quantum heat pump hot water systems.
6f.1: Six Month Service (By Owner)
To be carried out every six months. Operate the Pressure & Temperature relief valve for
approximately 10 seconds by activating the release mechanism on the valve to ensure water is
released to waste through the relief drainpipe.
It is very important that the mechanism is operated gently. Check to ensure the valve closes
correctly.
Note: providing some hot water discharge has been observed from the relief valve during normal
heating cycles, manually activating the valve is not necessary and could cause contamination / grit
to lodge in the relief valve seat causing constant leakage.
An inspection for any obvious signs of corrosion of the outer case or air intake grills should also
be conducted.
