Installation &

Maintenance

GENERAL

The ISD 220Q indoor units are designed to

be coupled with the OSA 220 outdoor units.

The ISD 265Q indoor units are designed to

be coupled with the OSA 265 outdoor units.

Units must be installed in accordance with

all national and local safety codes.

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two half length filters to be withdrawn from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.
