• Reduction of efficiency;
• Increase of electricity consumption;
• Bad control of internal temperature.
Check also that:
• The wall where the unit is installed can support its weight;
• The inside of the shelter is clean;
• The conditioner is not in the proximity of heat sources or warm air flows;
• The structure is watertight;
• If installed on a door, make sure the hinges can withstand the weight of the unit. Make sure that the
electric cable is not torn or damaged when the door is closed;
• If the depth of the cooling unit prevents the door from opening completely, arrange a stopper for
such a door.
6.2. Mechanical installation
DANGER
Before starting work, disconnect the power supply. Prior to drilling holes or making cuts, make
sure that holes, screws, cables, etc. do not interfere with the equipment which has already been
installed.
1. Make openings for evaporator air circuit and cable passage according to the cut-out drawings at
paragraph "3.3. Drawings".
2. Once cut-out openings have been made, suitably insulate them against water infiltration (rain).
3. Glue the adhesive gasket around the edges of the unit openings. The adhesive gasket consists of
ethylene propylene, open-cell type, 3 mm thick and 10 mm wide.
ATTENTION
Unit openings are larger than cut-out on the wall. Therefore the adhesive gasket must be
applied around the opening of the unit, not on the wall. Position of sealing gasket compared to
cut-out drawing is shown at paragraph "3.3. Drawings"
4. We recommend to provide the shelter with a support bar
for the air conditioner (not supplied with the unit). This
bar has two main functions: it decreases the mechanical
stress on the wall and it is a reference for a correct
position of the unit on the wall. Set the conditioner on the
support bar.
5. Lean the unit against the wall so that the openings on the
rear panel of the unit correspond to the openings cut on
the wall. Then, fix the unit to the wall through its lateral
brackets via suitable screws.
6. When also the electric installation is completed, put the
return and supply grilles / diffuser (accessories) in place.
