Check that the floats are leveled and the impurities, such as cables and
3
insulation foam, are cleaned. Cables are securely bound and not on the
water pan.
Check that the distance between two chilled water pipes outside the
4
cabinet is longer than 25 mm, the hose is securely wrapped with insulation
foam, and junctions are secured by using glue.

5
been completed.

Powering On the System
Power-On
7.1
1. Measure the input power voltage is within the
normal operating range (208V: –10% to +6%;
220V and 240V: –10% to +10%) by using
multimeter after powering on the front-end.
2. Subsequently switch on QF1 and QF2.
If there is an indicator, and the green indicator is
on, the primary power is serving the equipment.
If the green indicator is off and the system is
working properly, the secondary power is
serving the equipment.
