Machine Positioning; Cold Room Light Installation (Pre-Set Machines Only) - Keyfrost KBA Manuel

Machine positioning

1.2.2
For a correct operation of the machine, we recommend, when positioning the machine, that you:
- Position the cold room in an area that is well ventilated continuously and well away from all sources of heat.
- Do not install the machine on outside cold rooms.
- Check that the panels of the cold room are perfectly level.
- Position the machine in an easily accessible place, in order to facilitate inspections and maintenance operations.
- Position the machine in this part, where the most uniform cold distribution is possible.
- Ensure that the spaces around the air suction and exhaust grids of the machine are not blocked or reduced in size in any way
(Fig.1.2.2.a).
care must be taken when using the machine unit at altitudes of over 1000 m above sea level.
We recommend, during the installation phase, that you don't tilt the machine too far, in order to avoid the spilling of oil from the
compressor into the refrigerating circuit what damages the compressor. As a precaution, we recommend that you leave the unit
switched off for several hours, in order to avoid any possible problems.
The machine should be positioned in the cold room by a qualified technician and following the steps (A....I) given below. Tools required
are as follows: -hand saw; -screwdriver; drill.
A) Assemble the cold room flooring, outer walls and ceiling elements which are not in the vicinity of the area where the machine is to be
installed.
B) Make the necessary cuts and holes in the cold room panel, by respecting the formats given in the template (see techinical
documentation).
C) Lift the monobloc, using ropes (of adequate strength), which should be anchored to the two eyelets and remove it from the crate.
D) Position the machine at the prepared place. Take care to balance of the machine.
E) Connect the evaporator water outlet to the condensate evaporation tray, using the pipe supplied. Take care when inserting the outlet
heating (where fitted) into the syphon (Fig.1.2.2.b).
F) Fix the monobloc at its place by adjusting the angle brackets (1, Fig.1.2.2.c).
G) Assemble the remaining ceiling pieces on the cold room.
H) Insulate the cuts made on the cold room wall, using filler or silicone.
I) Install the possible accessories (cold room light, door resistor, door microswitch, compensation valve, strip doors) in the best position
for use.
If it's provided, we advise you to connect the overflow pipe of the condensation tray to a flexible hose for water drainage.
WARNING!! This machine has not been designed for installation in environments with a potentially explosive atmosphere.

Cold room light installation (pre-set machines only)

1.2.3
Install the cold room interior light (supplied) in a position that guarantees the best visibility inside the cold room. The tools required for
installation are as follows:
- screwdriver; - scissors; -drill.
• Fix the light fitting on the ceiling or wall of the cold room using the self-tapping screws provided "1" (fig. 1.2.3.a). If the light fitting is
being fitted to the cold room wall, ensure that the cable leads downwards, as shown.
• Remove the glass and protective grid from the light fitting by loosening the locking screw. Make a hole for the cable through the
stopper "3".
• Make a hole through the membrane of the cable gland "4" most suited to the installation type. Feed the cable marked "LC" (if it's
provided) from the machine through the stopper "3" and the cable gland "4". Pull out any excess cable (fig.1.2.3.b).
• Cut the cable down to size, remove the sheathing from the conductors and connect them to the relavant terminals of the light fitting.
Screw the stopper "3" to the cable gland and the light bulb (supplied) into the light fitting. Replace the light fitting glass and protection
grid.
