Mark out the A/H cut out as per fig. 7. Ensure the choice of

location satisfies the following:

A. The Facia panel will be centrally located.

B. The right hand edge of the cutout is a minimum of 50 mm

from right hand end of the cupboard. This will ensure that

when the A/H is installed, a minimum space of 25 mm exists

down the side of the A/H, as requested on page 3.

C. The left hand side of the A/H must be a minimum of 110 mm

from the LHS of the cupboard to allow pipes to be connected.

(Refer fig. 8)

D. The bottom of the cutout should be at least 75 mm above the

bottom of cupboard to allow the condensate drain to "fall"

away sufficiently.

Fitting of the 2 return air grilles/filters

■

Provided the cupboard is 525 mm wide or more, the two

grilles can be installed side by side in the underside of the

cupboard. (Refer fig. 9)

In the case of pop top vans, it may be convenient to install one of

the two through the top. Make sure however, that both are

installed.

Place the grilles as far back as is possible to allow the most direct

route of the air to the fan inlet.

Cut out size for each grille is 158 x 232.

The following describes the procedure for both a cupboard with a

removable front, and a cupboard with a front that is not easily

disassembled. Typically the latter type will have 4 to 5 mm ply

which will need reinforcing around the perimeter of the cutout

and tying to the main structural members of the cupboard assy.

Cut rectangular hole as detailed in fig. 7.

Use adhesive tape to stick down the template. Drill holes at the

corners of the cutout to allow a jig saw to cut out the entire

cutaway.

It is important to cut the hole out accurately.

If the front panel is a solid 19 mm panel, the A/H will not need

additional support. If however the front panel is light ply,

then this must be strengthened after cutting out as per the

template. This framing should be 20 mm thick to provide the

necessary support, and should tie in with the main cupboard

members, to support the weight of the Airhandler.

Installation of the refrigeration pipe work and

■

condensate drain

The 9.5 mm Ø and the 6.4 Ø pipes can enter either side of the

cupboard, and be carefully manipulated to make the connection to

the Airhandler. The 9.5 Ø pipe must be insulated entirely.

The condensate drain is normally run vertically. 12 mm hose or poly

pipe is preferred. Two elbows are provided in the installation kit to

change direction from the vertical run to the horizontal to connect

the airhandler. Failure to use this elbow usually results in a hump in

the drain which may impede drainage, or a kink refer fig.10.
