4.1 Installation Tips
The following procedures are to aid the operator in installing the Air Separator. All
procedures are to be performed by experienced, trained, and certified personnel only.
4” and larger Air Separators have lift lugs to aid in lifting and locating the unit. The
lift lugs are not intended to be used to support the Air Separators during
operation. Adequately sized and spaced supports/hangers should be used to
prevent damage or strain on the system piping.
1. The Air Separator should be located in a clean, open area, where it is easily
accessible for inspection, service and repair. Installation of the unit in an area with
adequate drainage is recommended.
2. A standard Air Separator is installed in-line of the system piping. Adequately sized
and spaced pipe supports/hangers should be used to prevent damage or strain on
the system piping.
3. When placing the Air Separator (AS Model) with strainer in the system piping, be
aware of the clearance required for strainer removal for cleaning and replacement
4. When piping the unit into system piping, the pipe size should be sized to allow
adequate flow at a minimal head loss, and be, at minimum, the same size as the
Air Separator connections. The use of fittings (elbows, tees and couplings) should
be kept to a minimum as well.
Some considerations: Isolation valves are required to allow gasket changes and
inspection of strainer. Expansion joints and or flex connectors are recommended to
prevent pipe strain caused by thermal expansion or piping misalignment. System by-
pass piping is also recommended in the event of system service and or maintenance.
With any piece of equipment utilizing boiler water or high temperature water under
pressure, there is a potential for severe personal injury or death if proper
installation, operation and maintenance procedures are not followed.
