Ducted
Fan Coil Units
Installation &
Maintenance
GENERAL
The IJD ducted fan coil units must be
installed in accordance with all national and
local safety codes.
Options
1. Filters
2. Electric Elements c/w fan run-on timer
3. Polyester powder coat finish
ELECTRIC HEAT (Factory Fitted Option)
Refer to wiring diagram for size of elements
supplied. A fan run-on timer for rapid heat
dissipation is included with this option.
A 24 hour power supply is essential for this
timer to function correctly.
INSTALLATION
Positioning & Mounting
Provide 1 m minimum clearance to both
ends of the unit.
The unit has a built-in sloping drain tray,
therefore mount it level.
Fasten the unit down to a firm flat horizontal
base using the six fixing holes provided in
the mounting rails. Use the bunged holes
provided in the base of the filter box to
access the mounting rail holes from above.
When the unit is being installed on a roof
it is recommended that the unit is installed
on a substantial structure with vibration
isolating springs beneath the unit. These
springs are not supplied with the unit.
Condensate Drain
The unit has an internal sloping condensate
drain tray. The drain exit should be trapped
outside the unit cabinet. The trap should
have a vertical height of at least 100 mm.
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. (Refer Fig.2).
For long condensate pipe runs, fit a vent
pipe near the drain trap. The top of the vent
pipe must be at least 100 mm above the IJD
unit's drain tray.
It is essential that the drainage system is
checked by pouring water in the drain tray
and seeing that it discharges at the end of
the drain and does not overflow the drain
tray.
ELECTRICAL WIRING
The electrical supply required is:
3 phase 380-415 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 40 A/ph.
