System Installation 

To achieve maximum performance of your system, the following should apply:
  • Ceilings must be insulated

Installation Procedure

As a reputable business our company is covered by all the necessary insurances, including: public liability, general business insurance and worker compensation. All work is performed to comply with occupational health and safety standards and applicable Australian safety standards.

When installing your system we take great care at all times to protect your premises and complete the job as quickly and efficiently as possible. All equipment packaging and installation debris are removed from the site and your premises will be left in a clean and tidy state.

Electrical work is carried out by Strathdee Electrical Pty. Ltd Lic. 127921C. 

This includes the installation of all electrical controls, interconnecting wiring between the indoor and outdoor units and installation of electrical sub mains connecting the air conditioning unit to the domestic switchboard.


We use quality refrigeration-grade copper piping to comply with both the manufacturer's standards and Australian standard AS1571. Both the suction and liquid refrigeration pipes will be insulated with industry-approved insulation.

Copper piping and electrical wiring running down external walls are encased in colour bonding insulation, where the colour is matched as close as possible to your existing down pipe or wall colour.
Ducted System Installation 
Door Unit
The indoor fan coil will be suspended by perforated straps within the roof cavity to minimise structural vibration and facilitate drainage. 

Outdoor Unit
The outdoor condenser will be located adjacent to the building mounted on a poly slab. We allow suitable "breathing" space of approximately 100mm (4") behind this unit,

*Please Note: Due to varying council regulations and the Noise Pollution Act the final location of the unit is critical. Whilst all care is taken with a recommendation, the final decision is yours.

Condensate water from the indoor fan coil unit will be disposed via a PVC drain terminating in the roof gutter. As a safety measure (in the event of this drain becoming blocked) we will install a galvanised drip tray beneath the fan coil which will drain separately through the eaves. (Usually near the front entrance)

*Please Note: If water is visible through the eaves drain, it indicates that the main drain is blocked and you need to call for service without delay to avoid possible ceiling damage. 

MDO (square) - These outlets are multi directional type with four-way removable blades to allow adjustment of air flow for summer or winter.

Return Air - Air is returned to the indoor fan coil unit via hinged return air grill outlet with removable filter, usually located in the hallway. This washable filter should be cleaned at regular intervals.
Wall Mounted Split System Installation
Indoor Unit 

The indoor fan coil unit will be wall mounted with an installation plate. 

The pipes from the indoor unit will be connected to the outdoor unit by running wires and pipe through a small hole behind the indoor unit.
