(1)

 GWP = global warming potential

Periodical inspections for refrigerant leaks may be required
depending on European or local legislation. Please contact your local
dealer for more information.

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. This maintenance should be
carried out by your local Daikin technician (see installation manual).

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

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

checking if the water pressure indicated on the manometer is
above 1 bar.

Only for the optional domestic hot water tank:

A check for correct operation of the 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.

REQUIREMENTS

Dismantling of the unit, treatment of the refrigerant, of oil and of other
parts must be done in accordance with relevant local and national
legislation.

Your product is marked with this symbol. This means that
electrical and electronic products shall not be mixed with
unsorted household waste.

Do not try to dismantle the system yourself: the dismantling of the
system, treatment of the refrigerant, of oil and other parts must be
done by a qualified installer in accordance with relevant local and
national legislation.

Units must be treated at a specialized treatment facility for re-use,
recycling and recovery. By ensuring this product is disposed off
correctly, you will help to prevent potential negative consequences for
the environment and human health. Please contact the installer or
local authority for more information.

DANGER

Do not touch water pipes during and 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.

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

WARNING

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 refrigerant 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.

CAUTION

If the supply cord is damaged, it must be replaced by the
manufacturer, its agent or similar qualified persons in order
to avoid hazards.

NOTE

During longer periods of standstill, e.g. during summer
with a heating only application, it is very important
NOT TO SWITCH OFF THE POWER SUPPLY towards
the unit.

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