8.8.4 Cleaning the Condenser Fan

•

Clean the EC fan with water only when temperatures are greater than 50°F (10°C)

•

Make sure that no water gets into the inside of the motor.

•

Do not hold the jet spray directly on the motor openings and seals.

•

During cleaning work using a jet spray, no guarantee is assumed regarding corrosion
formation/paint adhesion for unpainted/painted fans.

8.9 Replacing the Condenser Fan

WARNING! Arc flash and electric shock hazard. Open all local and remote electric power-supply
disconnect switches, verify with a voltmeter that power is Off and wear appropriate,
OSHA-approved personal protective equipment (PPE) per NFPA 70E before working within the
electric control enclosure. Failure to comply can cause serious injury or death. Customer must
provide earth ground to unit, per NEC, CEC and local codes, as applicable. Before proceeding
with installation, read all instructions, verify that all the parts are included and check the
nameplate to be sure the voltage matches available utility power. The Liebert® controller does
not isolate power from the unit, even in the “Unit Off” mode. Some internal components require
and receive power even during the “Unit Off” mode of the controller. The factory-supplied
disconnect switch is on the exterior of the enclosure. The only way to ensure that there is NO
voltage inside the unit is to install and open a remote disconnect switch. Refer to unit electrical
schematic. Follow all local codes.

WARNING! Risk of electric shock. Can cause serious injury or death. Open all local and remote
electric power supply disconnect switches and verify with a voltmeter that power is off before
working within the component electric-connection enclosures. Fan-motor controls can
maintain an electric charge for 10 minutes after power is disconnected. Wait 10 minutes after
power is verified as off before working within the fan electric control/connection enclosures.

WARNING! Risk of contact with high-speed, rotating fan impeller blades. Can cause injury or
death. Open all local and remote electric power-supply disconnect switches, verify with a
voltmeter that power is off, and verify that all fan impellers have stopped rotating before
working in the unit cabinet.

CAUTION: Risk of contact with hot surfaces. Can cause burn injury. The EC fans and
electronics housing are extremely hot during operation. Allow sufficient time for them to cool
to a touch-safe temperature before handling. Use extreme caution and wear appropriate,
OSHA-approved PPE when replacing or performing maintenance on the EC fans.
