Installation Procedure
Installation & Maintenance
1. GENERAL
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 to followed to avoid personal injuries.
The appropriate permits must be acquired and adhered to Seismic restraints must be fitted if required.
Local regulations on maximum boundary noise need to be considered when positioning the unit.
For some models (250 series):
All refrigeration pipe brazing, evacuation and charging shall be performed by a technician with a current Refrigerant
Handling Licence.
Hot Permits should be acquired where necessary before work commences.
Follow the Refrigeration Code of Practice Guidelines.
Piping and Brazing.
a.The Outdoor unit has shut off valves and uses swaged pipe connections.
b.The Indoor unit is shipped from the factory with pressured nitrogen.
c. Immediately before removing the brazed pipe seals from the Indoor and Outdoor units, relieve the pressure to
atmosphere after first ensuring the Outdoor unit shut off valves are closed.
d. Refer to supplied Specification Sheet for pipe sizing.
e. Use clean sealed refrigeration grade piping designed for R410A/R32.
f. Before brazing any pipe connections, ventilate the pipe concerned with low pressure nitrogen.
g. Use pipe cutters to avoid swarf.
h. Use long radius bends (2x pipe dia.).
i. Insulate both suction (gas) and liquid lines; seal all insulation joints.
j.10 Ensure open pipe ends are sealed until the final connection is made.
k. If the outdoor unit is to be installed above the indoor unit, then the suction riser should be trapped at the bottom
of the vertical and then again at 10 m (maximum) intervals. This is to ensure oil return to the compressor. The trap
should be a 'swan-neck' curve in the pipe, with no change in the pipe size.
Refer figure 3.

Positioning & Mounting
Clearances for servicing are shown in the Dimension diagrams on the supplied Specifications Sheet.
Separable Indoor Units (AD180S2SH5FA/ADH200H1ERG):
If splitting for ease of manoeuvrability:
a. Unpiug the Red and White sensor wires from electrical board and retract.
b. Undo the 5 nuts and separate the two halve.
Installing the split sections:
a. Use the 'L' shape brackets to hang both components.
b. Mount coil section level as drain tray has abuilt-in slope (not important for the fan section).
c. Re-connect sensor wires correctly to the electrical board.
d. Optional: Fit Spigot Plate Adaptors; refer Figure.
e. Fit insulated ducting to suit.Figure 1 Separable Indoor Unit (AD180S2SH5FA/ADH200H1ERG)
Installing the complete Indoor unit.
a. Use 'L' shape brackets supplied to
hang the unit on threaded rods or
suspension wires.
b. Optional: Fit Spring Mount Kit for
anti-vibration mounting, if required.
c. Mount unit level as drain tray has
a built-in slope.
NOTE: Open the cover plate,
disconnect the five bolts(1-5) and
