Before installing the CONTROLAIR Valve, all air lines in the
system should be blown clean to remove any moisture, dirt,
or harmful contamination. Strainers are furnished in the IN-
LET and OUTLET ports to protect the valve from large parti-
cles of foreign matter in the line. To further ensure long,
trouble-free service, a 10 MICRON or better filter should be
installed in the supply line to the valve.
The HE-2 Type CONTROLAIR Valve is designed for panel
mounting. The valve less pipe bracket can be installed from
the top of the panel. Refer to installation view page 3 for
panel opening dimensions. Allow suitable clearance for re-
moval of the pipe bracket cap screws which are 2 1/8" long.
NOTE: Each valve is packaged with a mounting
dimensions template.
INSTALLATION AND GENERAL MAINTENANCE
AND REPAIR RECOMMENDATIONS
Maintenance periods should be scheduled in accordance
with frequency of use and working environment of the
CONTROLAIR
Valve.
All valves must be visually inspected for wear and given an
"in system" operating performance and leakage test at least
once a year. If these visual observations indicate valve
repair is required, the valve must be removed, repaired and
tested.

A major overhaul is recommended at one million
cycles. However, where frequency of use is such that
it would require more than two years to obtain one
million cycles, the valve must be overhauled at the
two year period.
When it is determined that the
CONTROLAIR
Valve
requires a major repair as a result of the one million
cycles, one year routine inspection, or the two year
service period has elapsed, the device must be
disassembled, cleaned, inspected, parts replaced as
required, rebuilt and tested for leakage, and proper
operation prior to installation. Refer to MAJOR
REPAIR AND MAINTENANCE INSTRUCTION, page
13, and TEST PROCEDURES, page 14.
One complete CONTROLAIR Valve should be kept in
stock for each four valves in service. During the
maintenance period, replace the complete valve with
the "stand-by" unit. This will reduce production time
loss and afford inspection and replacement of worn
parts at a more appropriate or opportune time and
favorable location.
Notice that the operating portion of a valve can be
removed without disturbing the pipe connections
Remove the valve from the pipe bracket by loosening
four (4) screws and lift the unit free.
No special tools are required to maintain the
CONTROLAIR
Valve, with exception of internal
snap-ring pliers.
