d) Mount the seal housing making sure that the overflow
hole (3) is pointing upwards.
e) lnspect the new stationary seal cover (9) for any
surface împerfectîons and oil the surface with clean
refrigeration oil.
f}
Reptace the O-ring
(8)
In cover plate (9)
with
a new one.
IMPORTANT
Always insta// a new sea/ cover plate with a new sea/ assy.
Mount the new seal cover plate, align1ng it with the roll
pin (13), and tighten the screws diagonally and evenly so
as not to crack the carbon. Tlghten the 1/2 inch screws
to a torque of 108 N.m (80 lbfft).
g} Connect the oil supply tube and the drain line.
h) Run the oil pump to replenish the sea! housing.
,) Turn the compressor shaft a few turns by hand.
j) Close the pressure safety valve.
k)
Open the suction stop valve slowly to pressurize the
package.
1)
Check that the seal fs not leaking.
m) Open the discharge stop valve.
n) !f the compressor is
fitted
with an economizer por!,
open the economizer stop valve.
o) Mount the coupling spacer and coupling guard.
p) Reconnect the control cabine! to the electric supply
line.
q) Reconnect the starter to the efectric supply line.

The items to be inspected can be limited to only the checks
of cam settings and micro limit switch settings.
(A) INSPECTION
a}
Stop
the compressor with the stop button on the con
trol cabinel
b) Remove the black knob (1) tor manual control by
loosening the internal set screw.
c) Remove the four cover mounting screws
(3} and
remove the electric valve actuator
cover
(2).
d) Release motor brake by depressing the actuator
brake solenoid (5).
e) Measure live voltage to insure that actuatorîs receiv
ing full rated voltage.
f) Check cam/travel limit switch position to insure that one
switch is not made and that the actuator is within its nor
mal open-close rotation limits. This check can
be
made
using a volt meter connect between one side of the in
coming line (common) and one leg of the motor or capa
citor_ This check should show power between common
and one leg only.
Power
at
the common and both legs
or
no power at all,
would indicate
cam and
or wîring adjustment(s) are re
qulred.
