GENERAL
The ISD 220Q indoor units are designed to

Options
1. Filter Box.
2. Spring Mounting Kit
3. Electric Heater Box.
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
135 mm, instead of 60 mm.
ELECTRIC HEATER BOX (Option)
The Electric Heater Box is installed by
unscrewing the supply air spigot and
replacing it with the Electric Heater Box's
element-integrated spigot. This new spigot
has a depth of 195 mm, instead of 60 mm.
A separate page of installation instructions
is supplied with the Kit.
UNPACKING UNITS
In an area adjacent to the installation site
remove from the ISD unit from its carton
and examine it carefully for any damage
which may have occurred in transit. Record
any damage on the carrier's delivery
documents and refer the matter
immediately to the manufacturer's nearest
Sales Office.
INSTALLATION
Positioning & Mounting
Provide 500 mm minimum clearance to the
electrical panel. If the filter box option is to
be used, allow adequate clearance for the
two half length filters to be withdrawn from
either side of the unit.
If the Electric Heat Kit option is to be used,
allow adequate clearance for servicing.
If low noise is a critical factor in the
installation, refer to Figure 6 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 from four threaded
rods (not supplied) and use locknuts (not
supplied), as shown in Figure 3.
