operation
If circumstances allow:
▪ Do not place unfrozen liquids or foodstuffs in the cold room (when
used as freezer).
▪ Reduce the opening frequency of the cold room doors.
Always:
▪ Reduce the opening time of the cold room doors.
▪ Make sure that cold room doors are perfectly tight.
▪ Make sure that a good airflow is possible between the stored
goods.
▪ Check that the evaporator is ice-free. Ice forms on the evaporator
preventing air from flowing regularly. If necessary increase defrost
termination temperature by some degrees or increase frequency
of defrosts.

Maintenance and service

INFORMATION
Suitable maintenance is crucial for obtaining longer life,
perfect working conditions and high efficiency of the unit. It
also ensures the proper functioning of the safety devices
provided by the manufacturer.
7.1

Cleaning the unit

7.1.1

To clean the exterior

NOTICE
To clean the plate work:
▪ Do not use any cleaning agents or chemicals.
▪ Do not use pressurised water.
Clean with a soft cloth. If it is difficult to remove stains, use water or
neutral detergent and wipe with a dry cloth.
7.1.2

To clean the interior

DANGER: RISK OF ELECTROCUTION
▪ Turn OFF all power supply before removing the switch
box cover, connecting electrical wiring or touching
electrical parts.
▪ Disconnect the power supply for more than 10 minutes,
and measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing.
The voltage MUST be less than 50 V DC before you
can touch electrical components. For the location of the
terminals, see the wiring diagram.
▪ Do NOT touch electrical components with wet hands.
▪ Do NOT leave the unit unattended when the service
cover is removed.
CAUTION
Do NOT touch the heat exchanger fins. These fins are
sharp and could result in cutting injuries. Wear safety
gloves if you have to work on or around the heat
exchanger fins.
Operation manual
16
Good operation of the unit requires the condenser to be clean. The
frequency of cleaning depends on the environment where the unit is
installed.
INFORMATION
Under normal working
evaporator, and radiator coils should only be cleaned
during scheduled maintenance inspections.
1 Turn off the unit.
2 Clean the interior with a long-haired brush or by blowing (low
pressure) air from the inside outwards.
NOTICE
Do not use high-pressure water or air to clean the
condenser and evaporator fins. It will damage them and
prevent proper operation of the condenser and evaporator.
Should the fins nevertheless get bent:
3 Straighten them carefully using a fin comb for cleaning/
straightening.
7.2

Scheduled maintenance

Periodically check wear condition of electrical contacts and remote
switches. If necessary have them replaced by a qualified technician.
NOTICE
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, ON/OFF and emergency switches.
▪ Work on protection and safety devices.
Every 6 months Inspection and maintenance programs
● Check the alarm list.
● Check the condenser and clean if necessary.
● Check the evaporator and clean if necessary.
● Check drain pipe, see "7.3 To check the drain
pan pipe" [ 4 16].
