WARNING
Do NOT use water for cleaning. Use of water can damage
electrical components.
Good operation of the unit requires the condenser and evaporator to
be clean. The frequency of cleaning depends on the environment
where the unit is installed.
INFORMATION
Under normal working conditions the condenser and
evaporator should only be cleaned during scheduled
maintenance inspections.
Condenser heat exchanger cleaning
1 Turn off the unit.
2 Clean the condenser heat exchanger with a long-haired brush
or by blowing (low pressure) air from the inside outwards.
NOTICE
Do not use high-pressure air to clean the condenser heat
exchanger fins. It will damage them and prevent proper
operation of the condenser heat exchanger.
WARNING
Do NOT use water for cleaning. Use of water can damage
electrical components.
Should the fins nevertheless get bent:
3 Straighten them carefully using a fin comb for cleaning/
straightening.
Evaporator heat exchanger cleaning
1 Set the unit at minimum operating temperature and wait for ice
build‑up.
2 Activate the unit manual Defrost mode.
3 Check if the evaporator heat exchanger is clean.
4 Turn off the unit.
5 Clean the evaporator heat exchanger with a long-haired brush
or by blowing (low pressure) air from the inside outwards or with
(low pressure) water spray.
NOTICE
Do not use high-pressure water or air to clean the
evaporator heat exchanger fins. It will damage them and
prevent proper operation of the evaporator heat
exchanger.
INFORMATION
It is allowed to use water spray for cleaning the evaporator
heat exchanger. Water will go through the drain pipe. Make
sure the drain pipes are NOT clogged with dirt coming out
of the evaporator heat exchanger.
7.1.3 To clean the water circuit
In some applications, such as when using very hard water at high
temperatures, it may be necessary to clean the water circuit to
ensure the best operation of the plate heat exchanger.
Clean at regular intervals.
Clean the water circuit by putting a cleaning fluid into circulation.
1 Use a tank with a weak acid, e.g. 5% phosphoric acid or, if the
circuit is cleaned frequently, 5% oxalic acid.
2 Pump the cleaning liquid into the water circuit through the
(lower) water inlet connection (a) for the purpose of ventilating
the air. For optimum cleaning, the flow rate should be at least
1.5 times the normal rate, preferably in reverse mode.
a
3 Reverse the flow direction every 30 minutes, if possible.
4 Replace the cleaning acid with a 1-2% solution of sodium
hydroxide (NaOH) or sodium bicarbonate (NaHCO3) for the last
rinse, to ensure that all acid has been neutralized.
5 After cleaning, rinse the heat exchanger thoroughly using clean
water.
7.2
Scheduled maintenance
Periodically check wear condition of electrical contacts. If necessary
have them replaced by a qualified technician.

NEVER service or repair the unit by yourself. Ask a
qualified service person to perform this work.
Under no circumstances the user is allowed to:
▪ Replace electrical components.
▪ Work on the electric equipment.
▪ Repair mechanical parts.
▪ Work on the refrigerating system.
▪ Work on the control panel.
▪ Work on protection and safety devices.
