WARNING
Never operate the unit with any cover, guard, screen panel, etc., removed unless the instructions
specifically state otherwise, and then do so with extreme caution to avoid personal injury.
CAUTION
If a lifting device is used to move a unit, ensure it is capable of supporting the weight of the unit.
CAUTION
Do not use cleaning solvents near open flame or excessive heat. Wear eye protection when blowing
solvent from parts. The pressure-wash should not exceed 30 psig. Solvent solutions should be disposed
of in accordance with local and state regulatory statutes.
CAUTION
After the customer furnished supply and return piping is assembled, the piping system must be
thoroughly cleaned prior to connecting it to the unit. Failure to do so will result in equipment problems.
CAUTION
After the supply and return piping is connected to the unit, the entire system must be flushed prior to
beginning operation.
CAUTION
When installing and filling the water/glycol loop, all air must be bled from the piping system.
CAUTION
Once in service, a CyberWall™ unit should not be drained and taken out of service for an extended period
of time. Formicary corrosion can occur.
CAUTION
When the air conditioner is in the cooling mode, the return air-intake and discharge (supply) must be free
of obstructions. Ensure panels are secure and latched into position.
