Installation &
Maintenance
GENERAL
The IMD ducted fan coil units must be
installed in accordance with all national and
local safety codes.
Options
1. Filter Box
2. Spring Mounting Kit
FILTER BOX (Option)
The Filter Box is installed by unscrewing
the return air spigot and replacing it with
the Filter Box's filter-integrated spigot. The
filter may be accessed from either side of
this spigot. This new spigot has a depth of
150 mm, instead of 65 mm.
INSTALLATION
Positioning & Mounting
Provide 500 mm minimum clearance to both
ends of the unit. If the filter box option is to
be used, allow adequate clearance for the
filter to be withdrawn to its full length.
If low noise is a critical factor in the
installation, refer to Figure 5 for noise
isolation recommendations.
It is recommended that the unit be mounted
using the spring mounting system, supplied
as an optional extra (Fig.2). This system
minimises transfer of vibration into the
building structure.
If a more rigid installation can be tolerated,
then suspend the unit using the four straps
supplied, as shown in Figure 3.
Alternatively, holes are supplied in the
mounting flange for the use of threaded
mounting rods (not supplied).
The unit has a built-in sloping drain tray,
therefore mount it level.
Condensate Drain
The condensate drain should be trapped
outside the unit cabinet. The trap should
have a vertical height of at least 50 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.4). Use
flexible tube to connect the unit's drain stub
to the external drain pipe.
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
IMD 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.
Note: The built-in drain tray can be
removed for cleaning (or fan access) by first
removing the unit's base.
