INSTALLATION
Unpacking
The unit's supply air spigot has been
secured inside the unit for ease of shipping.
Remove the spigot and secure it in place
using the existing screws.
Positioning & Mounting
Provide sufficient clearance to the access
panels.
Mount on a suitable level platform using
vibration isolators. Access to fixing centres
beneath the return air spigot can be made
via the removeable bungs in the spigot's
base.
Condensate Drain
The unit has an internal sloping condensate
drain tray. The trap should have a vertical
height of at least 100 mm. The drain should
have a slope of at least 1 in 50 and must not
be piped to a level above the unit drain tray
(refer Fig.2).
For long condensate pipe runs, fit a vent
pipe near the drain trap. The top of the vent
pipe must be at least 100 mm above the ISD
unit's drain tray.
It is essential that the drainage system
for the evaporator is checked by pouring
water in the drain tray and seeing that it
discharges at the end of the drain and does
not overflow the drain tray.
INDOOR-OUTDOOR UNIT CONNECTIONS
Refer to the relevant OSA Outdoor Unit
'Installation & Maintenance' pamphlet for
piping instructions. For wiring connections,
refer to the Outdoor Unit wiring diagram.
