- Fig. 7 -
5.3.- Indoor coil condensed water drain
- The condensed water drain line must have a siphon for
correct discharge (see Fig. 7).
- The diameter of the tubing used must be at least equal to
the connection provided on the side of the unit.
- Use sealing putty on male threads.
- If it is necessary to install a drain line from the connection
of the unit to a nearby drain, maintain a minimum 2 cm.
pitch per each meter in length.
- It is recommended that the siphon be equipped with a plug
at the bottom for draining and cleaning.
- Prior to unit start-up, the siphon should be primed (filled
with water) and then checked during maintenance opera-
tions.
6 - Electrical characteristics and connections
6.1.- Basic units D4IC/D4IG/B4IH
6.2.- Units with backup heaters
- D4IC/B4IH
Heater power supply should be independent of general unit power supply and have its own automatic switch, as per the
following table:
6.3.- Power and control wiring
Job site wiring and grounding of the unit should be car-
ried out in compliance with national, local and city regula-
tions.
The voltage tolerances to be maintained at the compres-
sor terminals during start-up and operation appear on
the Identification Plate and in the Table of sections 6.1
and 7.
The inner wiring hose supplied with the unit is an integral
part of same. No variation at job site should be necessary
for compliance with electrical regulations.
An automatic and differential switch should be installed on
job site for the unit. This switch should be independent of
all other circuits. Should any of the cables supplied with
the unit need replacement, the replacement cable should
be of the type shown on the wiring diagram. See Wiring
Specifications Table.
The power supply line should be adequately sized for the
load.
Use copper wires only . Each one of the units should
be connected to an independent circuit with an automatic
and differential switch, supplied directly from the main
panel.

Important: Automatic switch sizing and power supply and control cable sections are orientative and should be corrected in accordance with job site
conditions, length between units and legislation in force.
