Section 5: SAFETY INFORMATION
DO NOT TURN ON POWER UNLESS THE TANK IS FULL OF WATER
5a: Safety Devices
WARNING: For safe performance this water heater is fitted with:
1. Digital Controller.
2. A thermostat (connected to the digital controller) to manage water temperature.
3. A thermostat (connected to the digital controller) to manage compressor temperature.
4. A non self-setting thermal cut out (incorporated into the digital controller).
5. Combination Pressure & Temperature relief valve.
These devices
must not
be tampered with or removed.
The water heater
must not
be operated unless each of these devices is fitted and in working
order.
This appliance is not intended for use by young children or the infirm without supervision –
young children should be supervised to ensure that they do not play with the appliance.
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.
