INSTALLATION INSTRUCTIONS 19
protectIve anoDe
note
The sacrificial anode must be checked by a qualified contractor 12 months after the unit has been installed
and checked periodically thereafter as advised by the qualified contractor. Failure to do so may void your
warranty.
An anode for the protection of the DHW cylinder is inserted centrally from the top into the DHW cylinder of the
appliance. The anode fitted at the factory (anode rod) is approximately 1.26 m long.
f f
Replace the anode with a new one if the installed one has been consumed.
A cap over the anode terminal prevent the ingress of water between the anode terminal and the condensate pan.
f f
Remove the cap if you need to remove the anode.
When installing the anode, ensure that the metallic conductor connection is correctly made. It's recommended for
first anode inspection to happen one year after installation.
Consult with your water specialist, or contractor, for the optimum timing for inspections thereafter.
Should it be
impossible to insert a rod anode, you may have a sectional anode installed instead. In areas where total dissolved solids
(TDS) in the water is outside the range 40-400 mg/l, the magnesium alloy anode supplied, M2, must be replaced. Use a
high potential, M1, anode if TDS < 40 or an aluminium A5 alloy anode if TDS > 400, before installing the unit.
f f
Push the cap back over the anode terminal.
f f Fill in sacrificial anode replacement log.
cleanInG the evaporator
!
WarnInG Injury
The evaporator has many sharp-edged fins. When cleaning the evaporator, proceed with caution and wear
protective clothing, in particular safety gloves.
Maintaining the full output of the device requires an occasional professional cleaning of the evaporator. Clean the
evaporator only with water and a brush. Never use acidic or alkaline cleaning solutions.
DraInInG the cylInDer
!
WarnInG Injury
Hot water can be expelled during draining.
f f
Close the shut-off valve in the cold water supply.
f f Fully open the hot taps at all draw-off points.
f f
The cylinder is drained via the cold water inlet line. Open the drain valve. If no drain valve was installed, undo
the fitting on the cold water supply of the appliance. Residual water remains in the lower part of the cylinder.

materIal loSSeS
If the hot water unit is not used for two or more weeks, an amount of highly flammable hydrogen gas may accu-
mulate in the water tank. To dissipate this gas safely, it is recommended that a hot tap be turned on for several
minutes or until discharge of gas ceases. Use a sink, basin or bath outlet, but not a dishwasher, clothes washer
or other appliance. During this procedure, there must be no smoking, open flame or any electrical appliance
operating nearby. If hydrogen is discharged through the tap, it will probably make an unusual sound as with
air escaping.
safeTy valve (on-siTe)
This valve opens when the water pressure exceeds the preset value of 0.7 MPa thereby relieving the pressure. It
is adjusted so that no water will be expelled when heating is switched OFF. Should it continue to drip excessively,
either the valve seat has become contaminated, the water pressure is too high or the pressure reducing valve has
become faulty.
pressure reduCing valve (on-siTe provision)
f f
Check the valve for perfect function. Replace it, if required.
