Clearance
Allow adequate clearance on all four sides of the puri- fier for cooling air flow and for service and mainte- nance access. Above the purifier, allow at least

Location
Locate the purifier under cover in a clean, dry, well- ventilated area. Install the purifier on a level base. Pro- tect the purifier from heavy vehicles or other moving equipment likely to cause damage. Bolt the purifier to the foundation if the installation area is subject to vi- brations. A bolt hole is located in each leg.
Air Compressor Equipment
Air compressor equipment must be located and main- tained to prevent the entry of
Install the purifier downstream of an aftercooler and separator (with functioning drain valve) so that purifier inlet air is between 40°F and 100°F and contains no liquid water.
Ambient Air Temperature
Purifier ambient air temperature must be between 50°F and 100°F. Higher temperatures (up to 120°F) can be tolerated if inlet air flow is decreased (see Airflow sec- tion). Operation outside the recommended ambient temperature range will cause poor purifier perform- ance.
DANGER
Never operate the purifier in atmospheres be- low 50°F or above 120°F. Operation outside this range will cause poor purifier perform- ance and may result in illness, injury or death.
Air Piping and Connections
The customer must furnish all external piping. Piping must be rated for the maximum operating pressure and temperature given on the purifier data plate and must conform to applicable codes. Support all piping. Do not allow the weight of the piping to stress the purifier connections.
DANGER
Do not hydrostatically test the piping with the purifier installed in the air system. Water will damage the catalyst.
Connect the compressed air supply to the purifier inlet. Connect the breathing air distribution line to the puri- fier outlet. (See Table III for connection sizes.) Inlet
