2.- INSTALLING THE UNIT
BEFORE INSTALLING
- It is advisable to place the unit close to the installation site without removing it from the packaging.
- Do not put heavy tools or weights on the packaging.
- Upon receipt the unit and the packaging must be checked for damage sustained in transit and if necessary,
a damage claim must be filed with the shipping company.
- Check immediately for installation accessories inside the packaging.
- Do not lift unit by the condensate drain discharge pipe or by the water connections; lift it by the four corners.
(Fig.1)
- The grille panel is separately packed for maximum protection.
- Check and note the unit serial number.
SELECT LOCATION
- Do not install the unit in rooms where flammable gas or alkaline acid substances are present.
Aluminum/copper coils and/or internal plastic components can be damaged irreparably.
- Do not install in workshops or kitchens; oil vapors drawn in by treated air might deposit on the coils and
alter their performance or damage the internal plastic parts of the unit.
- Installation of the unit will be facilitated by using a stacker and inserting a plywood sheet between the unit
and the elevated stacker. (Fig.2)
- It is recommended to position the unit as centrally as possible in the room to ensure optimum air distribu-
tion. (Fig.3)
Generally the best louver position is the one which allows air diffusion along the ceiling.
Alternatively intermediate positions can be selected, or the louvers can be closed completely.
- Check that it is possible to remove panels from ceiling in the selected position, to allow enough clearance
for maintenance and servicing operations.

2.- INSTALLING THE UNIT
INDOOR UNIT LOCATION
Install the indoor unit in a position:
- Having sufficient strength to carry the weight of the indoor unit.
- Where the inlet and outlet grilles are not obstructed and the conditioned air is able to blow all over the room.
- From where pipes can be easily run to the outdoor unit.
- From where condensate can be easily run to drain.
- Check the distance between the upper slab and false ceiling to ensure the unit will suit the distance.
(Fig.4)

INSTALLATION METHOD
Cassette Indoor Unit:
- Using the installation template open ceiling panels
and install the suspension bolts as in Fig.6 below.
Ensure there is sufficient space around the unit
to service it. See Fig.5

2.- INSTALLING THE UNIT
- Ensure the ceiling is horizontally level, otherwise condensate water cannot drain.
- The casing is fixed to the slab with 4 drop rods. The rods should have two nuts and washers to lock the
unit in position. The Cassette brackets will then hook over the washers.
- When lifting the Cassette into position care should be taken not to lift the unit by the drip tray, which could
be damaged.
- Lift unit (without the air panel) with care by its four corners only. Do not lift unit by the condensate drain
discharge pipe or by the piping connections.
- Incline unit and insert it into the false ceiling. Insert the rods into the brackets slot.
With false ceilings minimum height (see table), it might be necessary to remove some T brackets of the
false ceiling temporarily.
- Using level guide, line up the unit with a spirit level, and keep dimension between the fiber glass body and
the lower part of the false ceiling.
- Line up the unit to the supporting bars of the false ceiling tightening the nuts and counternuts of the threa-
ded rods.
- After connection of the condensate drain piping and piping connections, check again that the unit is level.

2.- INSTALLING THE UNIT
- The spaces between the unit and ceiling can now be adjusted. Use the drop rods to make the adjustment.
- Check to ensure the unit is level. The drain will then automatically be lower than the rest of the drip tray.
- Tighten the nuts on the suspended rods.
DRAIN PIPEWORK
Indoor Unit:
- The unit is fitted with a condensate pump with a 500 mm lift.
- The unit is provided with 22 mm bore flexible hose 300 mm long.
- The flexible hose should be fitted into a 22 mm polyvinyl tube and sealed. The 22 mm drain must be
installed with a downward slope.
- On completion the drain line should be insulated.
WATER CONNECTIONS
- Water connections are fixed to the unit body to
avoid breaks when pipes are connected to valve
assemblies; it is advisable to tighten the connec-
tion with a spanner.
- The upper coil connection is supplied with air
purge valve, the lower connection with water
purge valve, suitable for 8 mm wrench or screw-
driver.
- Coil is partially drainable; it is advisable to blow
air into the coil for complete drainage.
- When the installation is completed, it is neces-
sary to wrap connecting pipe with insulation to prevent leakage to ceiling tile.
ELECTRICAL WIRING
- Remove covers A and B and install the connection cord.
- After wiring is complete install covers A and B.

2.- INSTALLING THE UNIT
INTERCONNECTING WIRING
- We recommend that screened cable be used in electrically noisy areas.
- To avoid electro-magnetic control systeminterference, always separate (5VDC) low voltage signal wires
from (220 Vac) power line.
- Do not install the unit where electromagnetic waves are directly radiated at the infra red receiver on the
unit.
- Install the unit and components as far as practical (at least five metres away from the electromagnetic
wave source).
- Install a noise filter if any harmful noise exists in the power supply.
MOUNTING FRONT PANEL ASSEMBLY
- Remove return grille from front panel.
- Tighten 4 studs as shown in Fig 17.
- Hang front panel on casing by push “U” shape wire to 90º position locking with “J” shape hook as shown
in Fig 18.
- Fasten M-6 nuts to the 4 studs as shown in Fig 18.
