3.7 CONNECTIONS BETWEEN THE EVAPORATOR AND CONDENSING UNITS
3.8 PIPE PREPARATION
The indoor unit must be connected to the condensing unit
via Flare connections with a refrigerator quality copper
pipe at the ends of flare nuts and insulated along the entire
length. It is absolutely necessary to respect the diameters
provided on IDRA INVERTER units otherwise the guarantee
Use only refrigeration quality copper pipes with a suitable
diameter for each model. The gas and liquid pipes must
absolutely be insulated with insulation that has a minimum
thickness of 6 mm.
NOTE:
1.
The magnetothermic and power supply specifications
have been calculated on the basis of maximum absorption.
2
. The power cable specifications are applied to a conduit
containing more copper cables tested at 40 ° C and resistant
to up to 90 ° C (see IEC60364-5-562). If the working
conditions change, the cables must be changed according
will be voided. If evaporator units with refrigeration fittings
different than those on the IDRA INVERTER units are used,
use dedicated reduction connections (attention: mount these
fittings on the evaporator unit).
Insert the flare nuts on the pipe ends before preparing them
with a countersink tool. The pipes, separately insulated with
the relative fittings can later be bound to the condensing
unit’s evacuation pipe and the electrical cables using clamps.
3.5 ELECTRICAL CONNECTIONS
3.6 REQUIREMENTS OF GROUND
1.
Installation must be carried out in accordance with national
regulations.
2.
Only a nominal voltage supply cable and an exclusive
circuit for conditioners can be used.
3.
Do not pull the power cord by force.
4.
Installation of the electrical cabinet must be carried out by
qualified personnel and instructed in accordance with current
regulations.
1.
The air conditioner is classified as a Class 1 ° appliance,
grounding must be reliable.
2.
The yellow-green cable is earthed and can not be used
for other purposes, fix the cable with self-tapping screws,
otherwise it may cause electric shock.
5.
The diameter of the power cord must be dimensioned
according to the needs of the machine and replaced once
deteriorated.
6.
Grounding must be reliable and the special cable must be
connected to a dedicated device. It must also be equipped
with a magnetotherm coupled to a differential switch with
sufficient capacitance and both magnetic and thermal
protections in the event of short circuit or overload.
3.
The grounding cable must be connected to that of the
building and the cable can not be connected to any of the
following locations:
(1) water tubes
(2) gas pipes
(3) drain hoses
(4) other places that the technical staff find untrustworthy.
