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.
ISD c/w ELECTIC HEAT OPTION
G
(Factory Fitted)
Units supplied with electric boost heat are
80
designed to conform to AS/NZS 3350.2.40
1997.
ISD 250Q–390Q: 3 x 3 kW elements
ISD 470Q: 3 x 4 kW elements
Note: Reverse Cycle systems fitted with
electric heat require an Outdoor Unit low
limit t/stat (supplied separately).
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two half length filters to be withdrawn from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 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.3). This system
minimises transfer of vibration into the
building structure.
