Connection To Water System; Electric Controls; Control Panel - Daikin LMCMD050 Bedienungs Und Installationsanleitung Handbuch

We advise to install a microswitch (not supplied) on the cold room door which will
- switch on the light in the cold room, stop the unit and
- override the temperature alarm (for about one hour after door closing)
every time the door is opened.
The necessary cable is available with the unit. Connect it keeping in mind the following:
microswitch closed = door closed.
ATTENTION
Above microswitch is not supplied with the unit. If the microdoor cable is disconnected
or damaged, the same conditions will occur as in case of open door and connected
microdoor.
"LN" RANGE units (LN = low temperature) are supplied with a cable for door heater connection, to be made using
a fuse suitable for the door heater used.
The unit is also equipped with a cable for cold room lamp connection (lamp voltage should be 230 V and lamp max
capacity 100 Watts).
ATTENTION
Do not connect microdoor, cold room light or door heater cables to the 230V line. Each
cable is equipped with a plate showing how it should be connected.
WARNING
Any defective electrical part should be replaced by trained personnel exclusively.
The electric connection should be effected by qualified personnel.
7.2

Connection to water system

This connection is only necessary if the unit has a water-cooled condenser. It is effected by following the
indications of the tags positioned by the INLET and OUTLET pipes. Connection pipes should never be smaller in
diameter than those on the unit. A minimum water pressure of 1 bar is required for correct operation of the unit.
