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.

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.

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. 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. 

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.
