5. Connect the drain pipe to a suitable
drain line with an appropriate slope to
allow free drainage. This drain line does
not require trapping. Test the drain with
water to ensure it clears safely.
DO NOT let the ISD unit’s condensate drain
exit into this safety drain tray.
ISD/OSA SYSTEMS
WITH ELECTRIC HEATER BOX
Replace the systems external fuse with
the size recommended in the table on the
Outdoor Unit's wiring diagram.
Note: Tandem indoor units with electric heat
may require greater fuse sizes on the power
supply.
DIP switch 2 on the SAT-2 Controller PCB,
located in the ISD electrical box, must be
set to 'On' (refer wiring diagram).
COMMISSIONING
Indoor Unit
1. Check that the thermostat is
correctly wired and set at the desired
temperature.
2. Check that the air filter (if fitted) is clean.
3. Check that the fan runs freely without
vibration.
4. Check condensate drain and safety
drain tray for free drainage.
Refer to Outdoor Unit Installation
Instructions in order to complete the start-
up and commissioning procedure for the
complete air conditioning system.
Demonstrate the SAT-2 Wall Control to the
owner/user, after having first thoroughly
familiarised yourself with the User's
Operating Instructions. This page is to
remain with the owner/user.
MAINTENANCE
Weekly For First Four Weeks
1. Check air filter (if fitted); vacuum clean as
necessary.
2. Check condensate drain for free
drainage.
Monthly
Check air filter (if fitted); vacuum clean as
necessary.
Recommendations for Noise Isolation
- particularly for high static installations:
1. Avoid installing units, with non-ducted return air, directly
above spaces where noise is critical.
2. Use flexible connections between unit and rigid ducting.
3. Use generously sized acoustically lined ducts.
4. If generous duct size is not possible, use turning vanes on
bends to reduce air turbulence (regenerated noise).
5. Use 90° bends in ducting to significantly assist in noise
reduction.

tray for free drainage.
2. Check heat exchanger coil; vacuum or
brush clean as necessary.
3. Check the tightness of the fan.
4. Check that fan motor is free running.
5. Check tightness of electrical connections.
6. Check air supply at diffuser outlets.
WARNING
This unit is designed for use ONLY with the
refrigerant HFC -410A (R410A). The use
of other refrigerants is NOT authorised or
approved by the manufacturer and may
cause operational problems such as poor
performance and efficiency, loss of capacity,
degradation of materials and refrigerant
leaks.
The use of flammable or explosive
materials as a refrigerant creates the
additional risks of fire and explosion
which may result in property damage,
personal injury or death.
