Installation and Commissioning Guide
Split Tri-Capacity
INSTALLATION PREPARATION (Pre-Installation considerations)
The following items must be considered before beginning the unit installation:
• Verify the unit capacities and ratings with the unit nameplate
• Make certain the floor or foundation is level, solid and have sufficient structural strength to support the unit and
accessories weight.
• Allow minimum recommended clearances for periodic maintenance and service access.
• Allow sufficient space above the unit for the outdoor air discharge. Condenser air inlet, located on the coil side of the
unit, requires sufficient airflow clearance for the optimum unit performance.
• Note the conditioned supply air and return air location. Ensure sufficient spaces are allocated for these purposes.
• Refer connection and location of condensate drain in the unit drawing and dimensions section of this manual.
• Wiring connections must be in accordance with the wiring diagram provided with the unit.
• Make sure all wirings are in accordance with local electricity authority regulations and standards.
• Do not install the unit close to an area where there is a danger of fire due to volatile, explosive, flammable and/or
hazardous materials.
• Ensure that spaces around the unit are free from any obstructions for optimum unit performance.
• Installer to ensure correct size/type that main circuit breaker and cable is installed in unit sub-mains to protect the sub-
mains and unit wiring.
• Installer to ensure correctly rated residual current device (RCD) is installed as per with the latest edition of the
AS/NZS 3000 (also known as Australian Wiring Rules).
• Secure the power cords and control cables that goes in/out the unit. Use the cable ties provided in the control box.
05. UNIT MOUNTING AND LOCATION
1. The units must be installed in accordance with relevant authority regulations.
2. Install the unit on a level and strong foundation.
3. Install anti-vibration rubber or isolation mounts (installer to supply) under all of the unit’s feet to help reduce noise and
minimize vibration transfer through the foundation. Ensure that all anti-vibration rubbers are rated to provide stable
support without impairing the unit’s structural integrity.
4. Diameter or width of anti-vibration rubber’s must be at least equal to the width of the actual feet to prevent deformation
overtime.
5. Level the unit to ensure good condensate drainage away from the unit.
6. Ample service access areas and minimum space allowance for airflow must be provided.
7. Avoid installing the unit in such a place where there is danger of fire due to leakage of inflammable fluid.
8. Ensure that the spaces around the unit are free from any obstructions for optimum unit performance.
