Unit installation procedure

On the split system we advise you to install the condenser and the evaporator in different points; more
precisely:
· The condenser can be installed as "projecting part" (on the frontal wall of the van) or "on the roof" (on
the roof of the vehicle).
· The evaporator is installed on the ceiling of the loading compartment.
Preparation of the fixing holes must be carried out using the special drilling templates.
N.B. Specific details for condenser fitting:
A) Check that the unit is supported adequately.
B) If support is not available, fill the gap under the position in which the condenser unit is to be installed with
polyurethane foam.
For this, use aerosol cans of polyurethane foam for building use.
C) Use the fixing holes for filling.
D) Wait until the polyurethan foam has hardened (check the catalyzation time of the specific product), then clear
the holes of foam residue.
E) Prepare four sections of the aluminium pipe supplied at a length below 4mm. of the fixture depth.
F) Insert the pipes into the holes, lock the fixture guys, then cover the fissures with silicon.
The refrigeration unit control box is installed in the cabin, beside the steering wheel, in a position comfortable
•
for the driver.
Avoid placement on the top part of the dashboard, as direct rays of sunlight may alter the value readings.
In systems with road functioning and mains with power supply (F10D and F10M) the battery connector and
•
the refrigerator connector must be installed in the cabin in a position easy to connect.
• The aluminium channel supplied must be fitted to protect the rubber tubing of the cooling circuit and the
electric cables.
N.B.: CHECK THAT THERE I S NO CONTACT BETW EEN THE ELECTRI C CABLE AND THE HI GH P RESSURE
RUBBER TUBI NG OF THE REFRI GERATOR SYSTEM
The system will work effectively if installation is carried out professionally:
•
Make sure that the cooling circuit is free of moisture (carry out a vacuum for at least eight hours). Humidity
•
can cause serious damage and system arrest.
• Check the type and quality of refrigerant fluid to put in the circuit.
After putting in the refrigerant fluid, check the correct operation pressure of the system using the two high
•
and low gauges.
Also check that the control devices (thermostat, pressure switch, etc) are working perfectly.
• Check that the cooling circuit does not present leaks of refrigerant fluid, no matter how minimal, as a leak
could cause system arrest, even after months of operation.
