VALVES MUST BE POSITIONED TOWARD HINGE SIDE. 5. Install main arm to top pinion shaft, perpendicular to door. Secure tightly with arm screw/washer (e).
6. Adjust length of forearm so that forearm is perpendicular to frame when assembled to preloaded main arm. S ecure forearm to main arm with screw/washer (f).
7. Adjust door’s closing speed and power, see page 4 for reference. 8. Snap pinion cap over shaft at bottom of closer or install (optional) cover with small screws (j).
Option B Instructions: 1. Using the measurements from diagram B, mark screw hole center locations. Mark four (4) location on frame to mount door closer and
two (2) locations on door to mount arm shoe.
2. Drill pilot holes in door and frame, drill 7/32” (5.5mm) diameter holes for wood screws or drill and tap #7 (.201” diameter)
for 1/4-20 machine screws. 3. Install adjustable forearm/arm shoe to frame using screws (a) or (b). 4. Mount closer onto frame using screws (c) or (d). SPEED ADJUST-

center locations. Mark four (4) location on door to
mount door closer and four (4) locations on inside
frame to mount parallel bracket.
2. Drill pilot holes in
door and frame, drill 7/32” (5.5mm) diameter holes for
wood screws or drill and tap #7 (.201” diameter) for
1/4-20 machine screws.
3. Install Parallel Bracket

SIDE. 5. Place main arm on closer pinion
shaft, indexing main arm mark “L” or “R with pinion
flat as shown in figure 1. Secure tightly with
screw/washer (e).
6. Remove arm shoe from
forearm (see figure 2). Install ROD end of forearm
to bracket using the screw (i). 7. With door closed,
adjust length of forearm so that the tip of the main
arm is approximately 1-1/2” (38mm) away from being
parallel with door, when connected to the forearm.
Secure with screw/washer (f). 8. Adjust door’s
closing speed and power, see page 4 for reference.
