UNIT LOCATION

UNIT LOCATION
DANGER
Appliances must not be installed where they may be exposed
to potentially explosive or flammable atmosphere.
DANGER
Les appareils ne doivent pas être installés à un endroit où ils
risquent d'être exposés à une atmosphère potentiellement
explosive ou inflammable.
IMPORTANT
Unit Performance will be significantly reduced at or above
7215 ft (2200 m) and should not be operated above this
altitude.
IMPORT ANT
La performance de l'unité sera grandement réduite à une
altitude de 7215 pieds (2200 m) et elle ne doit pas être
utilisée au-delà de cette hauteur.

Unpacking

Remove the banding straps and lift the cardboard lid. Remove
the fascia, packed in bubble wrap, and polystyrene packing
pieces to expose the unit.
When removing the unit chassis from the box, the four corner
brackets should be utilized for lifting. In order to protect the
fascia from dirt and damage, it should be returned to the box
until it is ready to be installed.

Blank Off Pieces

When supply air branch ducting is to be used, polystyrene
pieces for blanking off fascia openings are included with the
fascia packing. Up to two opposing sides may be blanked off.
See Installation – Duct Collars on page 9.

Preparation

Before any installation work commences, the condensing unit
location (where applicable), pipe work sizes and routes should
be designed in accordance with good refrigeration practice.
When locating the unit, consider the following:
1. Ensure the ceiling structure that is adequate for
the required mounting provisions as outlined in the
"INSTALLATION" section. Check the ceiling is capable of
supporting the total weight of the unit, piping, refrigerant
and condensate.
2. Before installation, ensure that the correct electrical power
supplies are available for the unit.
3. Piping, electrical panel and condensate pump access panel
should be readily accessible for maintenance purposes.
A clearance of 2 ft (0.61 m) is recommended around the
electrical panel and condensate pump access panel.
4. The unit should not be positioned less than 5 ft (1.5 m)
from a wall or similar obstruction, or in a position where the
discharge air could blow directly on to the thermostat.
5. The unit should not be positioned directly above any
obstructions.
6
6. For units with supplementary electric heat (Digit 9 = A), the
minimum clearance from the unit to combustible surfaces is
0 in (0cm).
7. The unit must be installed square and level.
8. The condensate drain should have downward slope (1
in per 100 in (2.54 cm per 254 cm)) in a horizontal run
between unit and drain. Maximum condensate pump lift is
30 in (76.2 cm).
9. There should be sufficient room above the false ceiling
for installing the unit. Minimum distance as shown in
Figure 6.1 and Table 6.1.
10. In case of high humidity, clogged or damaged condensate
piping, incorrect installation or faulty condensate pump,
water may drip from the unit. Do not install the appliance
where dripping water can cause damage.
