Fan Coil Units

Installation &

Maintenance

GENERAL

The IMDL ducted fan coil units are available

in Standard (-S), Medium (-M) or High (-H)

capacity motors, e.g.

IMDL 90-S, standard cap. 6 pole motor

IMDL 90-M, medium cap. 4 pole motor

IMDL 90-H, high capacity 4 pole motor

The IMDL ducted fan coil units must be

installed in accordance with all national and

local safety codes.

Optional

1. Supply air spigots adaptors,

2. Flexible hoses (uninsulated):

- 13 BSP (1/2") part no. 060-085-001

- 20 BSP (3/4") part no. 060-085-002

3. Electric heater elements (factory tted).

INSTALLATION

Positioning & Mounting

IMDL units are designed to be used with

simple, short duct layouts. Units should

be located as close to the space to be air

conditioned as acoustic criteria allows.

When determining the position of the fan coil

unit, allow adequate space around the unit

to facilitate water pipe/hose connections,

future servicing and maintenance. Ensure

there is enough working space in front of

the electrical access panel. Allow adequate

clearance for the lter to be withdrawn to

its full length from either end of the unit.

Alternatively the lter may be lifted out of its

track. Provision should be made for access

to remove the unit from the ceiling if the

need arises.

Left handed models have drain exit on

supply air side of the drain tray.

Install the unit suspended on threaded rods

or bolts and locking nuts (not supplied).

Alternatively mount each unit on vibration

isolators on a suitable platform.

The unit must be installed level. Use the

adjustable support bracket (see gure 3)

to lower the drain pipe outlet and provide a

slope in the drain tray.

WATER SUPPLY & RETURN

The IMDL unit's IN and OUT water

connections are male pipe threaded

(refer Fig. 1). Warning: over-tightening of

connections to the main water supply may

damage the unit.

It is recommended you use two temperzone

600 mm exible high pressure water

hoses. These have female pipe threaded

connections at each end. Maximum water

pressure for each hose is 1720 kPa (250

psi). The IMDL unit alone, excluding hoses,

will withstand 4480 kPa (650 psi).

Note:

1. Allow adequate clearance for the lter (if tted) to be removed.

2. Left handed models have drain exit nearer supply air side.

Hoses may need to be insulated to meet

local building regulations.

Poor quality water supply must be pre-

ltered and it is essential that adequate

water treatment is maintained, particularly

where open cooling towers are used.

Condensate Drain

The drain should have a slope of at least

1 in 50 and must not be piped to a level

above the unit drain tray. Fit a vent pipe

within 500 mm of the unit (see Fig.3).

Check the drain by pouring water into the

drain tray and ensuring that it clears.

ELECTRICAL WIRING

The electrical supply required is:

1 phase 220-240 V a.c. 50 Hz with neutral

and earth. The supply to have an isolation

switch adjacent to the unit but not attached

to the unit. Recommended external circuit

breaker size is 5 amp.

Electrical work must be carried out by a

qualied electrician in accordance with local

supply authority regulations and the wiring

diagram.

INDOOR FAN SPEED

The fan speed can be set to LOW, MED, or

HIGH - whichever best suits the application.

ELECTRIC HEAT (Option)

Units installed with electric heat elements

include both auto (90°C) and manual

(120°C) high temp. safety thermostats. If

the manual high temp. safety t/stat requires

resetting and the auto high temp. safety

t/stat does not reset, then the latter needs to

be replaced.

COMMISSIONING

1. Check that the thermostat is

correctly wired and set at the desired

temperature.

2. Check that the air lter is clean.

3. Check that the fan runs freely without

vibration.

4. Check condensate drain for free

drainage.

MAINTENANCE

Weekly For First Four Weeks

1. Check air lter; vacuum clean as

necessary.

2. Check condensate drain for free

drainage.

Monthly

Check air lter; vacuum clean as necessary.

Six Monthly

1. Check condensate drain for free

drainage.

2. Check heat exchanger coil; vacuum or

brush clean as necessary.

3. Check the tightness of the fan.

4. Check that fan motor is free running.

5. Check tightness of electrical connections.

6. Check air supply at diffuser outlets.

NOTE

The manufacturer reserves the right to

change specications at any time without

notice or obligation. Certied dimensions
