SITING (VENTILATION)

Before erecting the room ensure there is suffi cient ventilation in
the area where rooms is to be positioned. In operation the room
will dissipate a heat load in the area in question in region of
1 - 2,1 kW per hour when running. This heat must be removed
from the area by means of ventilation such as louvers or
extraction systems. If impractical, consult your supplier for the
possibilities of using our heat disposal system.
The refrigeration systems are designed to operate satisfactorily
in ambients between +5 and 32°C. Ensure that the fl oor area
to be used is level. Requirement of the eveneness is max ±3
mm/m. Correct any unevenness at this time. It is recommended
to leave a gap of 50mm minimum between a freezer room and
the fabric of the surrounding building for air circulation
purposes.
The fl oor under the freezer room should be treated against
moisture and ice. If needed, the fl oor elements can be
delivered with fl oor heating elements (optional accessory).
Before unpacking ensure there is suffi cient space where the
room is to be assembled, this includes height.

ASSEMBLY

Begin installation by taking packages as close to proposed site
as possible. When opening packages use correct tools and
wearsuitable personal protection equipment including gloves.
Before commencing installation acquaint yourself with the
operation of the panel locks. Using the allan key provided, turn
the tongue of the lock outwards, note the double action, where
the last part of the turn pulls the panels tightly together. Return
the lock to the original position. (pic. 2).
It is recommended that the coldroom fl oor is sealed to the site
fl oor with a mastic type solution, to prevent incrass of moisture/
vermin. The same applies to plinth sections on fl oor-less rooms.
Remember the site fl oor must be cabable of supporting the
coldroom and produce weight without distortion.

ROOM WITH STANDARD FLOOR

Place the fl oor panel or panels in situ, tighten the locks and
check the sides of the fl oor are in line. Check again the fl oor
is level, it must be correct before assembly of the wall panels
begins. Unevenness will cause panels not to align and the door
will not fi t correctly.With fl oorless rooms place plinth on fl oor,
ensuring the corners are at true 90° angles, (follow tip given
earlier) affi x plinth using fi xings provided. Ensure they
are level. Otherwise similar problems will occur as fl oored
rooms. If the fl oor elements of a freezer room are equipped with

independent from the unit. The cables are installed to be taken
out either from the side wall behind the unit or from the back
wall.
The heating cables are located inside the fl oor panel, on the
bottom surface. In mounting the panels, special care must be
taken to prevent damaging the cables.
Check the condition of the heating cables before and after
mounting by measuring the insulation resistance between the
conductor and jacket and the resistance of the heating cables.
The correct resistance values can be found from the connection
cable for the heating cable. Operating voltage is 230 V.
