Maintenance activities

In order to ensure optimal availability of the unit, a number of checks
and inspections on the unit and the field wiring have to be carried out
at regular intervals, preferably yearly.

The only maintenance which may be required by the operator is:

keeping the remote controller clean by means of a soft damp
cloth,

A check for correct operation of the field installed pressure relief
valve installed on your domestic hot water tank, has to be
carried out at least every 6 months: it is important that the lever
on the valve is actuated to prevent accumulation of mineral
deposits that may impair valve operation and to confirm that the
valve and discharge pipe are not blocked. The lever should be
operated slowly and smoothly to avoid a sudden rush of hot
water from the discharge pipe.
Failure to operate the relief valve actuating lever may result in
the water heater exploding.

Continuous leakage of water from the discharge pipe may
indicate a problem with the water heater.

If a discharge pipe is connected to the pressure relief device it
must be installed in a continuously downward direction and in a
frost-free environment. It must be left open to the atmosphere.

7.3.

Standstill

If the domestic hot water is not used for two weeks or more, a
quantity of hydrogen gas which is highly flammable may
accumulate in the domestic hot water tank. 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 at 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 a sound as of air escaping.

Each inspection has to be carried out by your local
Daikin technician and 

not by the user

.

Do not touch water pipes immediately after operation
as the pipes may be hot. Your hand may suffer burns.
To avoid injury, give the piping time to return to normal
temperature or be sure to wear proper gloves.

WARNING

Before carrying out any maintenance or repair activity,
always switch off the circuit breaker on the supply
panel, remove the fuses or open the protection
devices of the unit.

Do not touch live parts for 10 minutes after the power
supply is turned off because of high voltage risk.

Do not touch any switch with wet fingers. Touching a
switch with wet fingers can cause electrical shock.

Please note that some sections of the electric
component box are hot.

Make sure you do not touch a conductive section.

Do not rinse the unit. This may cause electric shocks
or fire.

Play it safe!

Touch a metal part by hand (such as the stop valve) in
order to eliminate static electricity and to protect the PCB
before performing service.

WARNING

Do not touch water pipes during and immediately after
operation as the pipes may be hot.

Do not touch the refrigerant pipes during and
immediately after operation as the refrigerant pipes
may be hot or cold, depending on the condition of the
refrigerant flowing through the refrigerant piping,
compressor, and other refrigerant cycle parts.

Your hands may suffer burns or frostbite if you touch the
pipes. To avoid injury, give the pipes time to return to
normal temperature or, if you must touch them, be sure to
wear proper gloves.

WARNING

Switching off the power supply stops the automatic
repetitive movement of the pump in order to prevent it from
getting jammed.
