3. HOW TO INSTALL THE UNIT
Minimum operation and maintenance area. (fig. 3-1)
Fig. 3-1
3-1 Suspending the Unit at the Ceiling
This unit uses a drain pump. Use a carpenter's level
to check that the unit is levelled.
Determine the pitch of the suspension bolts
the provided full-scale installation diagram
The full-scale diagram must be placed in the centre
between the "T" bars; the "T" bar
electrical components box
porary. Unit must be installed in false ceiling only. (fig.
3-2)
Before installing the unit, place the tubes, the electri-
cal wires and the condensate drain pipe in the proper
position for the connection.
Adjust the distance between the unit and the ceiling
(max 23 mm) using the nuts of the four suspension
bolts.
Verify also the distance between the suspension
bracket
and the ceiling
distance can cause noise in case the unit touches the
ceiling.(fig. 3-3)
3-2 Installation of the condensate drain pipe
Utilise a hard, well insulated PVC pipe
mm) and fix it to the unit using a flexible PVC or
gummy hose
; tighten firmly with hose bands
The connection must be well insulated, using foamed
polyethylene
(thickness 8mm). (fig. 3-4)
• If it is necessary to increase the height of the drain
pipe somewhat, the portion directly after the con-
nection port can be raised a maximum of 25 cm. Do
not raise it any higher than 25 cm
result in water leaks. (fig. 3-5)
• Do not apply force to the piping on the unit side
when connecting the drain pipe. The pipe should
not be allowed to hang unsupported from its con-
nection to the unit. Fasten the pipe to a wall, frame,
or other support
as close to the unit as possible.
(fig. 3-6)
• Do not install an air bleeder
water to spray from the drain tube outlet. (fig. 3-7)
• Do not install pipe with an upward gradient
the connection port. It will cause the drain water to
flow backwards and leak when the unit is stopped.
(fig. 3-8)
• Be sure to provide insulation for any drain piping
installed indoors.
Drill a 65 mm diameter hole, insert a PVC pipe. (fig.
