New Zealand. However, in areas where Total Dissolved Solids
(TDS) exceeds 2500mg/L, detrimental effects on water heater
performance and longevity will result.
Anode
Should your water supply have a TDS of greater than 600mg/L,
the installed anode must be aluminium (blue) or hydrogen gas
can accumulate at the top of the water heater in long periods of
no use. When this is likely to occur, the installer should instruct
the householder on how to dissipate the gas safely. This
process is explained under “Hydrogen warning” on page 4. Any
change of anode must be carried out by an authorised service
person.
Corrosive Water
Water deemed to be corrosive can attack copper parts causing
them to fail. When the water supply Saturation Index (check
with your local water supplier for additional information) is less
than -1.0, water is deemed corrosive and a corrosion resistant
heating element should be used. When the Saturation Index is
greater than +0.40, an expansion control valve must be fitted
on the cold water line after the non-return valve. Should the
Saturation Index 0.80, a low-watts density heating
element should be fitted by an authorised person.
When an ECV is required to be fitted, a small amount of water
may be discharged during the heating cycle rather than the PTR
valve.
IMPORTANT : Where fitted, gently operate the easing lever on
the ECV every six months and replace at intervals not
exceeding 5 years, or more frequently in areas with poor
quality water.
Please refer to the Water Quality Statement on Page 19, and
the Warranty Details on page 20.
Switching off the appliance
If you intend to not use the water heater for only a few days, we
suggest you leave it switched on. If the water heater is to be
switched off, the switch is generally marked and located in the
circuit board or next to the appliance. When the water heater
switch is turned back on, it may take several hours before
sufficient hot water becomes available.
Tariffs
In some regions Off-Peak Tariffs may be available for water
heaters. In these regions water heaters greater than 160L are
suitable for connection to either Continuous or Off-Peak
Tariffs. Where the household requirements for hot water
exceeds the water heater storage capacity, Continuous Tariff is
required. Where hot water demand is less than water heater
capacity, Off-Peak Tariffs may be applicable. Note that Off-
Peak tariff vary from region to region, however are generally
less expensive than Continuous Tariff rates (subject to local
regulations).
