CAUTION: Risk of contact with sharp edges, splinters and exposed fasteners. Can cause
personal injury.
Only properly trained and qualified personnel wearing appropriate safety headgear, gloves,
shoes and glasses should attempt to move, lift, remove packaging from or prepare unit for
installation.
CAUTION: Risk of explosive discharge of high-pressure gas. Can cause injury.
Relieve system pressure and verify that the indoor and outdoor units are Off before making
piping connections/disconnections.
Do not exceed the design pressure rating that is marked on the nameplate.
Do not install a shutoff valve between the compressor and the field-installed pressure relief
valve.
NOTICE
Risk of interference with building doorways, openings and passages. Can cause unit and/or building
damage.
Refer to the installation plans and measure the unit and building opening before moving the unit to verify
clearances.
NOTICE
Risk of improper storage. Can cause unit damage.
Keep unit upright and protected from contact damage.
NOTICE
Risk of improper forklift handling. Can cause unit damage.
Keep the forklift tines level and at a height that will fit under the skid.
NOTICE
Risk of improper refrigerant charging. Can cause equipment damage.
Refrigerant R-407C and R-410A are blended refrigerants and must be introduced and charged from the
cylinder only as a liquid.
When adding liquid refrigerant to an operating system, it may be necessary to add the refrigerant
through the compressor suction service valve. Care must be exercised to avoid damage to the
compressor.
Vertiv™ recommends connecting a sight glass between the charging hose and the compressor suction
service valve. This will permit adjusting the cylinder hand valve so that liquid can leave the cylinder while
allowing vapor to enter the compressor.
