5b: Important Note Regarding PTR Valve
The Pressure & Temperature relief valve should be checked for adequate performance or replaced
at intervals not exceeding 5 years, or less in areas where there is a high incidence of water
deposits. Providing there is some discharge from the relief valve during each heating cycle there is
no requirement to manually activate the release mechanism on the relief valve. There is a
possibility that manually opening the relief valve may allow contamination / grit etc to settle in the
valve seat causing continuous leakage. If the relief valve is operated manually it should be done
with care.
The Pressure & Temperature relief valve and the drain outlet pipe must not be sealed or blocked. It
is normal for small amounts of water to leak from the valve during each heating cycle.
Section 6: MAINTAINANCE & SERVICE INFORMATION
Your Quantum water heater is a completely sealed refrigeration system, similar to a household
refrigerator. The maintenance program to be employed on your Quantum is not much different to
that required for the maintenance of a standard electric water heater. However, Quantum warranty
may be void if any of the following conditions are not met or if the refrigeration lines or
components are damaged or altered in any unauthorized way.
6a: The Water Tank
The water tank must not be drilled or punctured. Drilled holes or punctures may damage the
refrigeration pipes located on the skin of the water tank. The Quantum tank is a patented design
and in fact forms the condenser of the unit; i.e. it is the hot side of the refrigeration circuit. The
coils wound around the outside wall of the tank heat the tank more efficiently than any other water
heater design. The coils are not in contact with the water so they never corrode or suffer from
scaling, meaning the efficiency of the tank will not diminish.
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
