DOOR CLOSER REPLACEMENT
1. Remove existing door closer and inspect the condition
threads of the mounting holes. If threads are stripped,
see below recommendations for re-drilling mounting
holes.
2. Using the existing mounting holes, install main body of
door closer at the top of door cap and door closer
hook to door panel using the new #10-24 ½” screws
provided.
3. Install cylinder to main body of closer with pins
provided. The cylinder will install in only one direction.
Install plastic cover over main body of door closer.
4. Pull roller arm of main body assembly towards interior
of walk-in before allowing the door to close. The
existing mounting holes will locate door closer to
operate properly. No other adjustments should be
necessary.
Recommendations for re-drilling mounting holes.
1. If new mounting holes are required, make sure to install
them within the margin that represents factory installed
tapping plate.
2. The door closer main body and hook will be arranged the
same as the existing door closer.
3. If door cap is installed with a heater wire, do not drill within
clearance area (See illustration).
4. Drill mounting hole with a #25 drill (approx. 15 in) and
thread 10-24.
5. For door closer hook, drill and tap mounting holes for
slotted holes first. When proper door closure operation is
accomplished, drill and tap for remaining holes. The roller
should touch and revolve slightly as it passes door closer
hook.
