Local defrosting on a LMSEY unit is still possible in two ways:
▪ Manually (from app, supervisory system or user interface).
▪ With parameter "dI" (maximum interval between consecutive
defrosts) taking control. This will happen when a network
connection fault occurs that lasts longer than the "dI" parameter
setting. Therefore the "dI" parameter must always be set.

Commissioning
CAUTION
Preliminary electrical system checks such as earth
continuity, polarity, resistance to earth and short circuit
must be carried out by using a suitable test meter by a
competent person.
WARNING
ONLY qualified persons should conduct commissioning.
Final checks for correct installation
Check that there is no air gap between unit and cold room
wall.
Check the labels of the wires connected to the door micro
switch and the door heater. The door heater wire is a live
wire, while the micro switch wire is a signal wire.
Swapping the wires will cause serious damage to the unit.
Check that all covers are closed correctly.
Check that the electrical wiring of the door micro switch,
door heater and cold room lamp are properly fixed to the
cold room panels.
Check that all the electrical wiring work is correctly
connected.
Check that all cable glands are properly tightened.
DANGER
   
Tripping over loose wiring can tear it loose and cause
electrocution and fire.

by frostbite.
▪ 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.
