Facility Fluid and Piping Maintenance

Installation (Applicable to all Models)

2.5.2Humidifier Supply Water—Optional Infrared

•1/4" supply line; maximum water pressure is 150 psi (1034kPa)

•Size humidifier supply line for 1 gpm (3.8 l/m), with a minimum water pressure of 20 psi (138kPa)

•Do not supply de-ionized water to the humidifier

2.6Facility Fluid and Piping Maintenance

Facility water and glycol quality remain a requirement throughout the life of the piping system. Fluid and piping system maintenance schedules must be established and performed. A local fluid maintenance program must be established that will evaluate fluid chemistry and apply necessary treatment. A periodic leak inspection of facility and unit fluid piping is recommended. Refer to 5.4 - Glycol Piping.

2.7Electrical Connections

Three-phase electrical service is required for all models in either 208, 230, 460, or 575 V, 60 Hz; or 200, 230, or 380/415 V, 50 Hz. Electrical service shall conform to national and local electrical codes. Refer to equipment nameplate regarding wire size and circuit protection requirements. Refer to electrical schematic when making connections.

A manual electrical disconnect switch should be installed within 5 feet (1.6 m) of the unit in accordance with codes, or a factory-supplied disconnect switch may be factory mounted within the unit accessible from the exterior.

! WARNING

Risk of electric shock. Can cause injury or death.

Potentially lethal voltages exist within this equipment during operation. Observe all cautions and warnings on unit and in this manual.

The Liebert iCOM® microprocessor does not isolate power from the unit, even in the “Unit Off” mode. The only way to ensure that there is NO voltage inside the unit is to install and open a remote disconnect switch and verify the absence of electrical power with a voltmeter. Refer to unit electrical schematic.

! WARNING

Risk of loose electrical wiring connections. Can cause overheating of wire, smoke and fire resulting in building and/or equipment damage, injury or death.

Use copper wire only and verify that all connections are tight.

NOTICE

Risk of improper scroll compressor phase sequencing. Could cause poor performance and compressor damage.

Three-phase power must be connected to the unit line voltage terminals in the proper sequence so that the scroll compressor rotates in the proper direction. Rotation in the wrong direction will result in poor performance and compressor damage. Use a phase sequence and motor rotation sensor to ensure that the three-phase power is correctly connected and the compressor is rotating properly.
