2. INTALLATION OF REFRIGERATED DISPLAY CABINET
2.1. CABINET LOCATION
Handling operations and installation of the cabinet are reserved for skilled
person.
Consult the Construction Manager or the person responsible for the installation of
unit. Ask them to inform you of its installation location or if there are any changes
to where it is to be installed.
Check that the installation location chosen is suitable. To do this, make sure that
there is no air flow present, as this could affect the units by blowing hot air into
them. The unit must not be installed near air conditioning air discharge openings,
ventilators, doors or other machines that, due to their location, could expel warm
air from their condensing units into the cabinet or onto its condensing unit.
The refrigerated display cabinet must not be installed in places where
explosive gases are present. Do not expose the equipment to
atmospheric agents.
If the chosen location is not suitable for the installation of the cabinet, inform the
Construction Manager or the person responsible for the supermarket accordingly,
so that they can either specify another location or make the necessary
modifications that would make the original location suitable (closure of air vents,
removal of ventilators, closure of doors, etc.).
During the installation (or while carrying out maintenance) you must always wear
proper safety equipment to preserve your security.
It’s mandatory to leave 8cm between the cabinet rear wall and the
supermarket wall to ensure the airflow.
Keep the condensing unit openings free from obstructions.
2.2. UPACKING
Unpacking is reserved for skilled personnel.
The refrigerated cabinet is protected by plastic wrapping. Remove this and take out
the accessories which can be found inside the cabinet:
INSTALLATIONANDMAINTENANCEMANUAL

DifusiónRestringidaInterna
Using a fork-lift truck or pallet-lift, lift the cabinet, remove the wooden or plastic
supports and replace them with the plastics bases that can be found inside the
cabinet with the other accessories.
Packaging materials (plastic bags, nails, screws, polystyrene, etc.)
should not be left within reach of children as they pose potential
sources of danger.
2.3. LEVELLING
Use the adjustable bases to level the unit. Poor levelling could result in problems
with the defrost-water drainage, which could then freeze and thus cause the unit to
break down.
Poor levelling could result in problems with the drainage of water
resulting from defrosting, which could cause the unit to break down.
IMPORTANT!
The surfaces that the lines are to be placed on may not be perfectly horizontal.
Therefore it would be best to first take the section of line that is to be placed onto
the highest part of the surface and screw its adjustable bases to their smallest
possible heights whilst allowing the section to remain horizontal. This will ensure
that the bases on the end sections do not need to be excessively extended.
2.4. THERMOSTATIC VALVE CONTROL
In order to obtain maximum evaporator efficiency, the expansion valves should be
adjusted to have a reheating value of 3 to 6 degrees.
When viewed from the front, the expansion valve is situated on the far left of the
unit.To ascertain the reheating value measure the evaporation pressure on the
Schrader valve, which is located on the unit. Read the pressure on the pressure
gauge, which also displays the temperature, Te, that corresponds to the
evaporation pressure.
Measure the exact aspiration line temperature using the thermocouple in front of
the thermostatic expansion valve bulb. This will ensure that you obtain the
temperature of the evaporator's exit, Tse. The difference between the two
temperatures is the reheating value, Tr, in the evaporator:
Tse-Te=Tr
To adjust the reheating remove the cap from the thermostatic expansion valve
reheating screw and turn it anti-clockwise to lower the reheating, or clockwise to
increase the reheating.
Turn the screw in no more than quarter turn movements at a time and wait 15
minutes between each adjustment so that the system can stabilize. Once an
adequate reheating value has been obtained, replace the cap on the thermostatic
expansion valve reheating screw and close its lid.
