Installation
Install the electric heater in the SICH unit as follows:
1)
In all cases, the
established national regulations
should be followed.
2)
Disconnect the power supply to the air conditioning unit.
3)
Install the magnetothermal and differential switches for
the heater in accordance with the indications appearing
in the table of General Characteristics and Wiring Dia-
grams.
4)
Remove the access covers to the controls of the SCOC,
SCOH, SOC or SOH and SICH units.
5)
Unpack the accessory, opening the top of the box. Make
sure the heater assembly has not been damaged dur-
ing transportation. Check the ceramic insulation and that
the heater wires are not in contact with any metal parts.
6)
Fit the electric heater in the mouth of the indoor fan panel
housing and drill eight 3 diameter holes for fastening.
Check to make sure that the reset push button of the F9
thermal switch (F9 and F11 in 2 stages) is accessible
and at the top. See Heater Location diagram.
7)
Fasten the PVC gasket supplied with the accessory, to
the frame surface of the heater adjacent to the indoor
fan panel.
8)
Fasten the heater to the panel with the screws supplied.
9)
Remove the electrical connections cover of the heater
and connect the power supply cables to connecting strip
X1 (or automatic switch F21 in 2 stages). Connect the
control cable supplied, between connector J1 of the A3
Auxiliary Resistance board (A4 in 2 stages) and con-
nector J10 of the A1 control board of the air conditioning
unit.
10) The installer should complete the electric circuit of the
heater by fitting an air flow control F14 (F14 and F15 in
2 stages) at the most convenient point of the ducts so
as to make sure the heater operates only when there is
sufficient air flow.
11) Connect power supply to the SCOC, SCOH, SOC or
SOH and SICH unit and the heater.
12) To configure the accessory, press the test button of con-
trol board A1 for over 2 seconds, until the red led on the
board goes on. Configuration will be complete when said
led goes off.
13) Check operation of the heater by selecting the Emer-
gency Heat mode at the ambient thermostat of the air
conditioning unit.
14) Assemble the electrical box covers of the heater and
the SCOC, SCOH, SOC or SOH and SICH unit.
Note:
Should an incorrect response of the system take place,
see the Operation section of the SCOC or SCOH, SOC or
SOH and SICH Installation Instructions. There you will find
the control functions of the A1 electronic board on the heater,
as well as its configuration, incidents identification, etc.
Loose cables can cause overheating of the terminals or incorrect
operation of the unit. Fire hazards may also arise. Therefore, make
sure all cables are connected tightly.
