INSTALLATION
The Model FR-RES must be installed in accordance with the following instructions:
NOTES
Do not use any sprinklers which have been subjected to potential mechanical damage. Do not use any sprinklers
which show deformation or cracking in either the Sprinkler or the Protector.
Prior to installation, sprinklers should be maintained in the original cartons and packaging until used to minimize the
potential for damage to the sprinklers that could cause improper operation or non-operation.
The Protector must remain on the sprinkler during installation. After the installation is completed, the Protector must
be removed to place the sprinkler in service.
Use a torque of 7 to 14 ft·lbs (9.5 to 19.0 N·m) to achieve a 1/2 inch NPT sprinkler joint. If you exceed the recommended
maximum torque, this could result in damage to the sprinkler inlet, which may lead to leakage from the sprinkler.
Use only Wrench FR-S or Socket FR-H for installation of Model FR-RES sprinklers. Use of any other wrench or socket
is prohibited and may cause damage to the sprinkler.
Do not over or under tighten the sprinkler due to an inadequate adjustment of the D1 or D3 Recessed Escutcheon.
Re-adjust the sprinkler fitting to correct the position.
Installing Procedure
Install Model FR-RES sprinklers by the steps and figures shown below. Use only D1 or D3 Recessed Escutcheons with Model
FR-RES sprinklers. (D1 Recessed Escutcheons are not listed for use with the 205°F heads. D3 Recessed Escutcheons are
required for the 205°F heads.) Use of any other recessed escutcheon is prohibited and may void the warranty and approvals.
Model FR-RES sprinklers are only to be installed in the pendent position with the waterway perpendicular to the ceiling.
Step 1
Install the Inner Ring of the D1 or D3 Recessed Escutcheon over the sprinkler threads, as applicable. (Ref. Figure 3 and 4)
Step 2
Apply pipe-thread sealant to the threads. Begin hand-tightening the sprinkler into the sprinkler fitting in the pendent position.
Step 3
Using the Socket FR-H or Wrench FR-S, tighten the sprinkler into the sprinkler fitting with a torque of 7 to 14 ft·lbs
(9.5 to 19.0
N·m). (Ref. Figure 5)
A 1/2" drive ratchet (not included) is required for use with the Socket FR-H.
Step 4
Remove the Protector by hand. (Ref. Figure 6)
Slide on the Outer Ring of the D1 or D3 Recessed Escutcheon over the Sprinkler and push the Outer Ring over the Inner
Ring until its flange comes in contact with the ceiling. (Ref. Figure 7)
