STEP 5.
Insert the hex key into the hole in the right
side of the compressor housing (See Fig. #2). Loosen
clamping screw at the base of the connecting rod.
Slide the connecting rod off the bearing, lift it out
through the top of the compressor housing.
NOTE:
It may be necessary to insert a flat tip
screwdriver into the slot in the base of the connecting
rod, and spread the base slightly, in order to break
the Loctite
®
bond and free it from the bearing (See
Fig. #3).

REBUILD VALVE PLATE
ASSEMBLY
STEP 1.
Remove the valve keeper and
intake valve flapper from the bottom of
the valve plate. Clean the bottom of the
plate with a clean soft cloth. Install the
new intake flapper valve. The valve keeper
should be placed on top of the flapper so
that the word “UP” is visible (See Fig. #4).
Tighten the screws to 12 in-lbs.
STEP 2.
Remove the two restraints and
four exhaust flapper valves (two over
each port) from the top of the valve plate.
Clean the top of the plate with a clean
soft cloth. Install the new flapper valves
and screws as shown in Fig. #5. Tighten
the screws to 12 in-lbs. Set Valve Plate
Assembly aside.

STEP 9.
Install the fan onto the eccentric nib. Align the slot marked ‘1007’ with the notch
on the eccentric nib. Insert the screw and washer into the threaded hole in the nib. Tighten
to 30 in-lbs. DO NOT OVERTIGHTEN. When properly assembled the fan will remain
centered in the housing when rotated by hand. NOTE: it may be helpful to insert the hex
key through the hole in the housing, and into the set screw hole in the eccentric. This
will prevent the eccentric from rotating while tightening the fan screw.
Caution
To avoid property damage or personal injury, always try rotating the fan by HAND
prior to connecting the unit to the power source. Check for suction at the air
inlet port by placing your finger over the port as you turn the fan. You should feel
a slight suction with each rotation of the fan. If you don’t feel suction, or if you
feel or hear a thump as you turn the fan, DO NOT CONNECT THE UNIT TO A
POWER SOURCE; review the assembly procedure for possible error.
