SAFETY DRAIN TRAY
The unit is supplied with a safety drain tray
to protect your ceiling against accidental
damage. The safety drain tray is best
secured to the ISD unit
after the unit has
been suspended in the ceiling, however it
is possible to fit it
before if circumstances
make this easier.
AIR FILTRATION / FILTER BOX (Option)
As air filtration requirements vary, filters are
not supplied with the unit. Filters should
ideally be installed on the return air side of
the unit, no closer than 500mm from the
back of the unit and easily accessible for
cleaning. To maximise the efficiency of air
flow, the return air filter should be twice the
area of the ISD unit's return air spigot/s. If
efficiency is less of a concern a Filter Box is
available.
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 Heat 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.
