Installation &
Maintenance
GENERAL
The IMDL-Y ducted fan coil units must be
installed in accordance with all national and
local safety codes.
Optional
1. Supply air spigots adaptors (refer Fig.2).
2. Flexible hoses:
- 13 BSP (1/2") part no. 060-000-270
- 20 BSP (3/4") part no. 060-000-271
- 25 BSP (1") part no. 060-000-272.
3. Electric heater elements (factory fitted).
INSTALLATION
Positioning & Mounting
Provide 500 mm minimum clearance to the
electrical box end of the unit.
Allow adequate clearance for the filter to be
withdrawn to its full length from either end of
the unit. Alternatively the filter may be lifted
out of its track.
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 figure 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: overtightening of
connections to the main water supply may
damage the unit.
It is recommended you use two temperzone
600 mm flexible 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).
Poor quality water supply must be pre-
filtered 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.
