NOTICE
Risk of improper water supply. Can reduce humidifier efficiency or obstruct humidifier
plumbing.
Do not use completely demineralized water with this unit. The water must contain minerals for
the electrode principle to work.
Do not use a hot water source. It will cause deposits that will eventually block the fill-valve
opening.
NOTICE
Risk of water backing up in the drain line. Leaking and overflowing water can cause equipment
and building damage.
Do not install an external trap in the drain line. This line already has a factory-installed trap
inside the cabinet (Except for 300-mm (12-in.) Chilled-water models).
This line may contain boiling water. Use copper or other suitable material for the drain line.
Sagging condensate drain lines may inadvertently create an external trap.
NOTICE
Risk of doorway/hallway interference. Can cause unit and/or structure damage. The unit may
be too large to fit through a doorway or hallway while on the skid. Measure the unit and
passageway dimensions, and refer to the installation plans prior to moving the unit to verify
clearances.
NOTICE
Risk of damage from forklift. Can cause unit damage. Keep tines of the forklift level and at a
height suitable to fit below the skid and/or unit to prevent exterior and/or underside damage.
NOTICE
Risk of improper storage. Can cause unit damage.
Keep the unit upright, indoors and protected from dampness, freezing temperatures and
contact damage.
NOTICE
Risk of release of hazardous substances into the environment. Can cause environmental
pollution and violation of environmental regulations.
The Liebert CRV contains substances and components hazardous for the environment
(electronic components, refrigerating gases and oils). At the end of its useful life, the
LiebertCRV must be dismantled by specialized refrigerating technicians. The unit must be
delivered to suitable centers specializing in the collection and disposal of equipment
containing hazardous substances.
NOTE: The Liebert indoor cooling unit has a factory-installed high pressure safety switch in the high-
side refrigerant circuit. A pressure relief valve is provided with Liebert Lee-Temp™ condensers. Consult
your local building code to determine whether the Liebert MC condensers will require field-provided
pressure-relief devices.
