1. GENERAL
Temperzone OPA Outdoor Air Cooled Packaged units.
Follow these instructions to ensure the optimum
performance, reliability and durability.
Units must be installed in accordance with all national and
regional regulations and bylaws. National Health and Safety
regulations must be followed to avoid personal injuries.

2.1 Mounting
The unit should be fastened to a firm flat horizontal
base using the holes supplied in the mounting
channels. When the unit is being installed on a roof it is
recommended that the unit is installed on a substantial
structure with vibration isolating springs beneath the
unit. These springs are not supplied with the unit.
Flexible duct connections are recommended between
the supply and return ducts and the unit.
Unit is shipped with wooden blocks installed under the
compressors. Ensure these blocks are removed from
the compressor feet prior to starting the unit
(not required for operation).

The appropriate local permits must be acquired and

Local regulations on maximum boundary noise need to
be considered when positioning the unit.
Factory filter slides are fitted, access to the filter access
door should be considered when designing return
and supply air ductwork. Access to the filters can still
be achieved by removing the return air access door,
however it is imperative that the rubber insulating
washers be refitted to the screws prior to replacing
the panel.
2.2 Condensate Drain
The condensate drain should be 'U' trapped outside the
unit. The trap should have a vertical height of at least
100 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
pipe. (refer fig. 2)

    9. PERFORMANCE DATA Air Handling Note: Airflows are for a dry coil. Reduce airflow by 5% In high moisture removal conditions. In a free blow or low resistance application, beware of exceeding indoor fan motor’s full load amp limit (refer back page). As filters are optional, the fan air flows given are for units installed without filters.

CONTROLS 10.1 Modbus Connections The bridging wires should be screwed to terminals A and B separately and should be long enough to be used as the bridging cables between the 24 V hot terminal and compressors 1 and 2. If in the event a TZT is not used, they can stay there and not be of anyone’s concern.
