6b: Air Evaporator Coils
Quantum water heaters use evaporator coils to extract heat from the air. The coil is extremely
efficient in warm humid weather; however, as temperatures drop to ten degrees or less the coil
will begin to collect ice. The coil has been designed with "heat injection" to defrost the coil under
such conditions. The heat injection cycle is automatic and is managed by the digital controller.
It
is important that the air inlet vents are kept clean. Restriction of air-inlet or outlet vents
may void warranty if the system has been damaged because of insufficient airflow
.
6c: Sacrificial Anode
A sacrificial anode is fitted inside the vitreous enamel lined cylinder. Its purpose is to help protect
the cylinder from the corrosive effects of water. Normally, the sacrificial anode should be
inspected every fifth year and replaced if necessary. In areas where “hard water” or poor quality
water conditions exist, the sacrificial anode must be inspected every second year.
Replacement
anodes must meet Quantum quality specifications and must be appropriate for local water
conditions.
The anode socket in the top of the tank is an RP

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.
