Installation Instructions

7500 Series

P7500

Multi Size - 1 thru 6 Non Hold Open Door Closers Models - 7500 J7500 JL7500

CAUTION

An incorrectly installed or improperly adjusted door closer can cause property damage or personal injury. These instructions should be followed to avoid the possibility of misapplication or misadjustment.

• With or without suffix "DA" (Delayed Action) closing.
• With or without suffix "M" with metal Cover.

Note:

The closing force for series 7500 door closer is adjustable from a size 1 to a size 6, as outlined in ANSI Standard A156.4. When this series of door closer is installed and adjusted to conform to ADA reduced opening force requirements (5 lbs max.) for interior doors, it may not have adequate closing force to reliably close and latch the door. Power adjustments charted on pages 3,4 and 5 are recommended where possible, to ensure proper door control.

For Special Applications a separate door and frame preparation template is packed with these instructions. Use this instruction sheet for installation sequence and closer adjustments only.

• It is recommended that the door, on which the door closer will be installed, be hung on ball bearing hinges. Door must swing freely.
• A separate door stop, supplied by others, is recommended to prevent damage to the door closer, closer arm; or to the door, frame or adjacent walls.
• · Door and Frame must be properly reinforced, or use of special fasteners employed, to prevent the mounting screws from pulling out.
• All dimensions are given in inches with corresponding metric dimensions (millimeters) in parentheses.
• Door closer should never be installed on the exterior of a building.

Installation Sequence

Select angle of opening and use dimensions shown in template and chart to locate 4 holes on door for closer body (or 4 holes for optional 7786 backplate) and 2 holes frame face for arm shoe.

For applications that are different from above, a separate template will be supplied for door and frame preparation.

• Prepare door and frame for fasteners using "Preparation for Fasteners" chart, Figure 2, Page 2.
• Fasten optional 7786 backplate to door, only if it is required for the door conditions.
• Install closer body with tube end away from hinge, with valves:

Down for Left Hand door UP for Right Hand door.

• Fasten arm shoe (with adjusting rod) Figure 1, Page 2 to frame face.
• Install main arm onto closer pinion shaft, aligning arm mark "S" with the one flat corner of the square shaft "Pinion Flat", see illustration at right. Secure with hex washerhead main arm screw.

Remove forearm screw from adjusting rod on frame and open door slightly to slide adjusting rod into slide unit. Close door and rotate arm away from hinge until adjusting rod and slide unit are perpendicular (at a 90° angle) to door. Install and tighten forearm screw.

Make closer adjustments, if required, using information below and on Page 6, then install closer cover.

Install closer per instructions with the proper pre-load applied to the arm then adjust spring power. The power adjustment will not work properly if the closer spring is not pre-loaded. To increase power, use 11/16" wrench to turn power adjustment nut clockwise. To decrease power, turn nut counter clockwise.

Fasten arm shoe (with adjusting rod) Figure 1, Page 2 to door face.

Note that a longer adjusting rod or different arm might be required for your frame conditions, see illustration with "Reveal Range" chart to the right.

Install main arm onto closer pinion shaft, aligning arm mark "S" with the one flat corner of the square shaft, "Pinion Flat", see illustration at right. Secure with hex washerhead main arm screw.

Remove forearm screw from adjusting rod on door and open door slightly to slide adjusting rod into slide unit. Close door and rotate arm away from hinge until adjusting rod and slide unit are perpendicular (at a 90° angle) to door. Install and tighten forearm screw.
