Installing The Control Panel And Door Switch - Gram KPS 120 Montageanleitung

4. Installing the control panel and door switch

The control panel is to be installed at the wall module beside the door. The
top of the control panel must be placed 80 mm above the ceiling of the room
according to illustration 20+21. The wiring is to be lead from the evaporator
out through the wall module and directly into the control panel. Please be
aware that the hole in the wall module fits with the position of the hole in the
control panel. To be sure, use the template for marking the hole positions.
See illustration 18.
Illustration 22 shows the structure of the control panel.
Wires for connection of fans, heating elements, temperature sensors etc. will
not have the sufficient length, if the control panel is not placed within the
recommended area.
Door switch
The door switch is placed directly in the control panel. The control panel is
therefore always lefthand hinged.
The door switch is activated magnetically. Therefore a magnet has to be
placed on the side of the door, opposite of the door switch. The magnet is to
be screwed onto the door. If the blast chiller is with 2 doors, and fitted with 2
switches, they must be connected in parallel, not in series.
Procedure:
1. Use the template for marking the room panel where to drill holes for
mounting of the control panel and the wiring lead-through. (Template is
in the box with loose parts.)
2. Drill holes.
3. Install pipe and muffs for wiring lead-through (contained in the box with
loose parts)
4. Install the control panel.
5. Screw the magnet onto the door, opposite the door switch.
6. Pull wires, temperature sensors etc. through the hole in the wall module
to the control panel. Rember to relieve the wires with relief bushes or
strips to the relief rail. The power cord is to be lead in through the room
