2. INSTALLATION

2.1 Clearances & Service Access
Refer to Specification Sheet supplied for minimum
clearances. If multiple units are to be placed side-by-
side then allow at least 2m between coil faces.
Filter slides are fitted within the unit. Access to the filter
access door should be considered when designing
return and supply air ductwork. Access to the filters can
also be achieved by removing the return air access door.
2.2 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 pads or mounts. If
placed on the ground or concrete pad, use rubber pads
or mounts to give 20mm min. ground clearance.
Flexible duct connections are recommended between
the supply and return ducts and the unit.

3. REFRIGERATION SYSTEM

3.1 General

The OPA 1400/2100 has four independent refrigeration
systems and four inverter compressors to provide the
flexibility and economy of four stage operation, i.e.
utilising one to four systems as conditions vary, plus
the advantage of staggered starting, all stages being
variable for improved control and system efficiency.
Each refrigeration system has been charged with
HFC-410A (R410A) refrigerant; refer Specifications
document for amount.

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.
The appropriate local permits must be acquired and
adhered to.
Local regulations on maximum boundary noise need to
be considered when positioning 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).
2.3 Condensate Drains
The condensate drains should be 'U' trapped outside
the unit. The traps should have a vertical height of at
least 100 mm. The drain lines should have a slope of at
least 1 in 50 and must not be piped to a level above the
unit drain pipe.

3.2 Compressors
The compressors are inverter scroll type. The
compressor lubricant is polyolester oil (POE). Note, this
oil absorbs moisture quickly if exposed to open air.
