The ICU will not turn on.
Note: When you press the main on/off switch, the amber light in
the switch should come on, and the ventilating and circulating fans
should start.
First: Check the electric power cord. Make sure it is firmly
plugged in at both ends.
Second: If this is a new installation, does it meet the
requirements outlined under Electrical Requirements on Page 34?
If not, you may be tripping a building circuit breaker because your
supply line is inadequate. Call your local electrician and have the
correct line installed.
Third: Check to see if either circuit breaker on the unit has
tripped. Refer to Re-setting the Circuit Breakers on Page 60.
CAUTION: Before working on the electrical system,
make sure the unit is Off and the electric power cord
un-plugged.
Fourth: Open the electronics compartment and make sure that
the wire connections inside the electric power cord connection and
the system ground are tight. Refer to Figure 24 on Page 21.
Fifth: When the main on/off switch is On, the amber light in the
switch should be on. If this light does not illuminate, check the wire
connections on the back of the switch. If they are all secure, you
may have a bad switch. Order P/N 853422 and refer to Page 99
for replacement instructions.
Sixth: If these actions do not resolve the problem, call SSCI
