3n: Refrigeration Connections (Split Models Only)
Refrigeration pipe work is very specialized and should only be completed by a licensed
tradesperson.
Maximum refrigeration pipe length from the tank connections to the evaporator is 9m.
If the evaporator is mounted below the tank connection point, then a suitable oil trap needs to be
installed on the suction line between the evaporator and the heat pump.

Section 4: OPERATING INSTRUCTIONS
4a: Filling The Water Heater
Open all hot water taps. Open isolating valve at the cold-water inlet and allow the water heater
to fill until water flows through the system. Close each hot water tap after the air is expelled from
its line.
4b: Water Quality
Your Quantum water heater has been manufactured to suit the water conditions of most Australian
and New Zealand metropolitan supplies. Please note that harsh water supplies can have a
detrimental effect on the water heater and its life expectancy. If you are unsure about your water
quality you can obtain information from your local water supply authority.
By using the correct anode this water heater can be used in areas where the Total Dissolved Solids
(TDS) content of the water supply is up to 2500 mg/L. In areas where the TDS exceeds 750mg/L it
is possible that the magnesium alloy anode (supplied in the heater) may become over reactive. To
alleviate this, the magnesium alloy anode should be replaced with an aluminum alloy anode
(Note: Quantum does not supply this).
4c: Caution When Left Operating But Unused
If the water heater is left in an operating condition but unused for two weeks or more, a quantity
of hydrogen gas (which is highly flammable) may accumulate in the top of the water cylinder. To
dissipate this gas safely it is recommended that a hot tap be turned on for several minutes at a sink,
basin or bath, but not a dishwasher, clothes washer or other appliance. During this procedure there
must be no smoking, open flame or any other electrical appliance operating nearby. If hydrogen
gas is discharged through the tap it will probably make an unusual sound similar to air escaping.
