INSTALLING THE CONDENSER SET

Marking out the floor

■

Use the floor template as provided (or refer to fig. 3). Both, or either end of the con/set may be hard against

a wall or panel, but the back of the unit must have sufficient clearance to allow easy access to the line

valves (see fig. 4). Once a convenient position has been decided upon, place the template, side marked

"Inside Wall", hard against the inside skin of the van, and mark out the six 114 mm diameter (4

condenser air inlet holes, and the square compressor well hole (see fig. 3).

Note: Check to see if any structural floor members will interfere with any of these holes. It is essential that

the compressor well is unimpeded. The compressor feet project through the well by 4 to 5 mm, therefore

clearance of at least 8 mm must be maintained between the well and any floor members. Eg. Angles or

tubes. Lack of clearance will result in noise and vibration. See fig 5.

The air inlet holes will tolerate some obstruction.

However the total area must not be less than 75% of

the inlet holes in the chassis. DO NOT install fine

mesh (flywire) over the inlet holes.

We recommend that a hole saw be used to cut out the

six round holes. If a structural member is beneath,

then the complete cut out can be removed. The gap

between the top of the structural member and the

underside of the unit (i.e. the floor thickness) will

help in overcoming the restriction of the member.

Marking out the wall

■

Now mark out the hole in the wall for the condenser

discharge grille (see fig. 5).

Mark out the position and size of the air outlet hole,

from inside the van, using the floor as reference.

Pilot holes can be drilled at the four corners, and the

hole cut out from the outside. It is essential to frame

up this hole to give a firm seal to the air outlet from

the con/set and to stop any discharge air from

entering the wall space.

Positioning of the Con/set

■

Lay down a generous bead of silicone on the floor to

match the perimeter of the Con/set. Now, lift the Con/

set into position, and check that the compressor well

does not interfere and prevent the con/set from sitting

firmly on the floor.

Push the Con/set hard up against the wall.

It is vital that the Con/set seals hard against the

inside wall to ensure no hot air leakage during

operation.

To secure the Con/set in position, use the three hold

down clips provided (see fig. 4). These clip over the

edge of the chassis. At least one clip should be

installed on the back edge to ensure the good airseal

is maintained against the inside wall. Screw the clips

firmly to the floor.
