CAUTION
Use Piping Strainers!
To prevent condenser damage, pipe strainers must be installed in the water supplies
to protect components from water borne debris. AIR is not responsible for equipment
damage caused by water borne debris. 0.5 to 1.5 mm mesh recommended.
Proper Water Treatment!
The use of untreated or improperly treated water may result in inefficient operation and tube
damage due to scaling, erosion, corrosion, algae or slime. It is recommended that the services of
a qualified water treatment specialist be engaged to determine what water treatment is required.
AIR assumes no responsibility for equipment failures which result from untreated or
improperly treated water, or saline or brackish water.
Condenser or Water Coil Damage!
To prevent damage to water components, do not allow pressure
(maximum working pressure) to exceed 125 psig @ 150°F.
