7.7.4 INLET CONTROL SOLENOID VALVE (P/N
250025--516) MAINTENANCE
Refer to Figure
. Solenoid valve (P/N
250025--516) maintenance is quite minimal but a pe-
riodic cleaning is desirable. The time between clean-
ings will vary depending on operating conditions. In
general, if the voltage to the coils is correct, sluggish
valve operation or excessive leakage will indicate
that cleaning is required. If parts replacement is re-
quired, order repair kit no. 02250053--334 (valve)
and no. 250031--431 (coil) and follow the procedure
explained below.
WARNING
!
Turn off all power, relieve package pressure, and
disconnect coil lead wires to the valve before mak-
ing repairs. It is not necessary to remove the valve
from pipework for repairs.
DISASSEMBLY AND REASSEMBLY
1. Remove the retaining clip from top of solenoid.
CAUTION
!
When metal retaining clip disengages it will spring
upward.
2. Remove nameplate, cover and spring washer.
3. Slip yoke containing coil, sleeves, insulating wash-
ers (omitted from molded coil) and grounding wire
off solenoid base sub--assembly.
4. Coil is now accessible for replacement.
5. Reassemble in reverse order of assembly.
CAUTION
!
Solenoid must be fully reassembled because the
housing and internal parts complete the magnetic
