PLACING OF GOODS IN THE COLD/FREEZER ROOMS
In placing goods, especially in the freezer room, special
attention should be paid to suffi cient free air space around each
package to ensure a proper air circulation. Do not place or stack
packages or boxes in front of the air movement fan. Goods
should be in closed packages.
ELECTRICAL CONNECTIONS
Before connecting the machinery to mains electricity
ensure that the voltage is the same as that shown on the
refrigeration unit serial plate. Ensure a separate supply is
provided for each room being installed. The refrigeration unit is
supplied with a fl exible cable with a molded electrical plug top
with fuse. Three phase models require an isolating switch fuse.

Installation of the mains cable (pic. 15). Plug the cable into the
socket located at the upper left corner of the unit (1). Install the
upper front cover and fasten it by the aid of the lock plate (2).
Secure the lock plate by tightening the two screws.If a freezer
room is equipped with fl oor heating cables, they should be
connected to an independent power supply.
OPERATION
All refrigeration units are pre-tested in the factory and the
operational temperatures can be adjusted as follows:
a) coldrooms (C) +2°C/+12°C (34°F/50°F)
b) chiller rooms (M) -2°C/+5°C (23°F/34°F)
c) freezer rooms (F) -22°C/-18°C (-8°F/0°F)
Before using the room check that the operational
temperature is reached. If the operational temperature is not
achieved read through the “Operational Faults” section of these
instructions before you call in a maintenance engineer. A strong
smell due to the cleaning agent or silicon mastic may appear in
the room, in which case the room should be washed with a mild
detergent suitable for the purpose, then dried and ventilated for
at least 24 hours.
RHDS-SYSTEM
If a room is to be placed in an area where there is little or no
ventilation you should consider selecting the unique Porkka
‘Remote Heat
Disposal System’. This is a method of removing waste refri-
geration heat to either and external area or a more ventilated
position and alleviates heat build-up where the equipment is
situated, which in return reduces electrical consumption and
operational costs.
Please consult you Porkka sales offi ce for further information.
TO AVOID EVAPORATOR DAMAGE IT IS
IMPORTANT TO KEEP FOOD WHICH IS HIGH IN ACID
SUCH AS VINEGAR BASED SAUCES OR VERY HIGH
SALT CONTENT IN CLOSED LIDDED CONTAINERS.
DO NOT REMOVE ANY PANELS OR GUARDS OR THE
ELECTRICAL CONTROL PANELS BEFORE
DISCONNECTING THE UNIT FROM THE MAINS
SUPPLY BY REMOVING THE PLUG OR THE FUSE
FROM SOCKET.

AS THE CONDENSER COOLING AIR EXITS THE
UNIT AT THE TOP IT IS ESSENTIAL THAT THE
APERTURE IS NOT OBSTRUCTED WITH BOXES,
PACKING MATERIAL ETC.
