CAUTION
When connecting the power supply and control wiring to the unit,
waterproof type wires
must be used to avoid water or humidity
getting into the unit during normal operation. These waterproof
conditions also apply when a switch is installed at job site.
See Fig. 8 for typical wiring on job site.
NOTES:
1. All job site wiring should be carried out in compliance with
all city and local standards and/or regulations in force at
the time of installing the unit.
2. Should it be necessary to remove any cables supplied
with the unit, these should be replaced by cables of the
HO5V-K, HO7V-K or equivalent type, and be numbered
clearly for identification purposes.
. Motors are intrinsically protected, except for the indoor
fan motor, which has external protection.
4. This unit is wired for operation with a 415 V power sup-
ply.
5. See the Identification Plate for the maximum size of the
automatic switch and minimum power supply cable sec-
tion.
6. All motors are factory wired to rotate in the correct direc-
tion.
Thermostat
The ambient thermostat should be located on an inner
wall, at about 1.5 m. above floor level, where it will not be
exposed to air flows, direct sunlight or heat from other elec-
tric devices. For general installation, follow the instructions
supplied by the manufacturer. To connect the thermostat to
the unit, shielded colour-coded 10 x 0.22 mm² wires should
be used.
