Installation and General Maintenance Recommendations
WARNING: INSTALLATION AND MOUNTING
The user of these devices must conform to all
applicable electrical, mechanical, piping and
other codes in the installation, operation or re-
pair of these devices.
INSTALLATION! Do not attempt to install,
operate or repair these devices without
proper training in the technique of working
on pneumatic or hydraulic systems and de-
vices, unless under trained supervision.
Compressed air and hydraulic systems con-
tain high levels of stored energy. Do not
attempt to connect, disconnect or repair
these products when a system is under
pressure. Always exhaust or drain the pres-
sure from a system before performing any
service work. Failure to do so can result in
serious personal injury.
MOUNTING! Devices should be mounted
and positioned in such a manner that they
cannot be accidentally operated.
Installation and General Maintenance Rec-
ommendations
Before installing the Controlair
lines in the system should be cleaned to re-
move all dirt, moisture or contamination.
A strainer is furnished on the inlet port to pro-
tect the valve from large particles or foreign
matter in the supply line. To ensure long, trou-
ble-free service, a 10 micron or better filter
should be installed in the supply line to the
valve.
The HC-2 Controlair Valve is designed for
panel mounting. The valve less the pipe
bracket can be installed from the top of the
panel. Refer to the installation view for panel
opening dimension. Allow suitable clearance
for installing or removing of the (3) pipe bracket
screws which are 2 1/8" (54mm) long.
GENERAL MAINTENANCE AND REPAIR
RECOMMENDATIONS
Maintenance periods should be scheduled in accor-
dance 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 leak-
age test at least once a year. If these visual observa-
tions indicate valve repair is required, the valve must
be removed immediately and repaired.
A major overhaul is recommended at one million cy-
cles. However, where frequency of use is such that it
would require more than two years to obtain the one
million cycles, the valve must be overhauled at the two
year period.
When it is determined that the Controlair Valve re-
quires a major repair as a result of the one million cy-
cles, one year routine inspection or the two year ser-
vice period has elapsed, the device must be disassem-
bled, cleaned, inspected, parts replaced as required.
The valve then must be tested for leakage and proper
operation prior to installation, refer to the Major Repair
and Maintenance Instructions and test procedures.
Notice that the operating portion of the valve can be
®
Valve, all air
removed without disturbing the pipe connections by
just removing the (3) screws that hold the pipe bracket
to the valve.
No special tools are required to maintain the Controlair
valves, with the exception of internal snap– ring pliers.
One complete Controlair valve should be kept in stock
for every (4) valves in service. During the maintenance
period, replacing the complete valve with the stand-by
unit reduces production down time and affords inspec-
tion and replacement of parts at a more appropriate
time and favorable location.
