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 14.5 psi (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.

TROUBLESHOOTING

The guidelines below might help to solve your problem. If you cannot

solve the problem, consult your installer.

DISPOSAL REQUIREMENTS

Dismantling of the unit, treatment of the refrigerant, of oil and of other

parts must be done in accordance with relevant local laws and

regulations.

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 laws

and regulations.

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.

POSSIBLE CAUSES CORRECTIVE ACTIONS
