Outdoor Unit Instalation; Electrical Conections; Outdoor Unit Condensed Water Drainage - White-Westinghouse WASC09C2ADLW Instruction Manual

Outdoor unit installation
1. The outdoor unit should be installed on a solid wall and fastened securely.
2. The following procedure must be observed before connecting the pipes and
connecting cables : decide which is the best position on the wall and leave
enough space to be able to carry out maintenance easily.
3. Fasten the support to the wall using screw anchors which are particularly
suited to the type of wall.
4. Use a larger quantity of screw anchors than normally required for the
weight they have to bear to aviod vibration during operation and remain
fastened in the same position for years without the screws becoming loose.
5. The unit must be installed following the national regulations.
6. Do not install the outdoor unit near sources of heat, steam or flammable
gas.
7. Do not install the unit in too windy or dusty places.
8. Do not install the unit where people often pass. Select a place where the air
discharge and operating sound level will not disturb the neighbours.
9. Avoid installing the unit where it will be exposed to direct sunlight ( other
wise use a protection , if necessary, that should not interfere with the air
flow). Leave the spaces as shown in the picture for the air to circulate freely.
10.Install the outdoor unit in a safe and solid place. If the outdoor unit is
Outdoor unit condensed water
drainage (only for heat pump
models)
The condensed water and the ice
formed in the outdoor unit during
heating operation can be drained
away through the drain pipe.
1. Fasten the drain port in the 25mm
hole placed in the part of the unit
as shown in the picture.
2. Connect the drain port and the
drain pipe. Pay attention that water
is drained in a suitable place.

Electrical connections
1. Take the cover away.
2. Connect the cable wires to the
terminal board using the same
numbering as in the indoor unit.
3. For the electrical connections, see
the wiring diagram on the back of
the cover.
4. Fasten the cables with a cable-
clamp.
5. An efficient earth connection must
be ensured.
6. Replace the covers.
Connecting the pipes
Screw the flare nuts to the outdoor unit
coupling with the same tightening
procedures described for the indoor
unit.
To avoid leakage, pay attention to the
following points:
1. Tighten the flare nuts using two
wrenches. Pay attention not to
damage the pipes.
2. If the tightening torque is not
sufficient , there will probably be
some leakage. With excessive
tightening torque there will also be
some leakage, as the flange could
be damaged.
3. The surest system consists in
tightening the connection by using
a fix wrench and a torque
wrench:in this case use the table on
page 24.
