IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important safety instructions that should be followed during the installation and maintenance of the Liebert Mini-Mate2. Read this manual thoroughly before attempting to install or operate this unit. Only properly trained and qualified personnel should move, install or service this equipment. Adhere to all warnings, cautions and installation, operating and safety instructions on the unit and in this manual. Follow all installation, operation and maintenance instructions and all applicable national and local building, electrical and plumbing codes.

! WARNING

Arc flash and electric shock hazard. Disconnect all electric power supplies and wear protective equipment per NFPA 70E before working within 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 microprocessor control 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.

The line side of the disconnect switch on the front of the unit contains live high voltage. The only way to ensure that there is NO voltage inside the unit is to install and open a remote disconnect switch and check the internal power supply wires with a voltmeter. Refer to unit electrical schematic. Follow all applicable national and local electric codes.

! WARNING

Risk of explosive discharge from high-pressure refrigerant. Can cause injury or death.

This unit contains fluids and gases under high pressure. Relieve pressure before working with piping.

! WARNING

Risk of refrigerant system rupture or explosion from overpressurization. Can cause equipment damage, injury or death.

If a pressure relief device is not provided with the condenser unit, the system installer must provide and install a discharge pressure relief valve per national and local codes in the high side refrigerant circuit. Do not install a shutoff valve between the compressor and the field-installed relief valve. Do not isolate any refrigerant circuits from overpressurization protection.

! WARNING

Risk of high-speed moving parts. Can cause injury or death.

Open all local and remote electrical power disconnect switches, verify with a voltmeter that power is Off and the blower, pulleys and belts have stopped moving before working in the unit cabinet.

! CAUTION

Risk of contact with hot surfaces. Can cause injury.

The refrigerant discharge lines, humidifiers and reheats are extremely hot during unit operation. Allow sufficient time for them to cool before working within the unit cabinet. Use extreme caution and wear protective gloves and arm protection when working on or near hot discharge lines, humidifiers and reheats.
