Precautionary Warnings for Corrosive Environments
Model FR-QR sprinklers should not be installed where they may be subjected to a corrosive environment including the
following:
(1) Chlorine ion and Chloride environment.
Stress corrosion cracking may be caused by exposure to environments with Chlorine ion and Chloride. Exposure to this
environment may result in sprinklers operating under Non-Fire conditions or Not Operating when exposed to an actual fire.
(2) Sprinkler system piping with Copper.
Sprinkler systems should be constructed in compliance with the applicable standards and the requirements for copper piping
when copper piping is used in the sprinkler system. (Reference standards NFPA 13, ASTM B813, B828, and CDA (Copper
Development Association) – Solder Joint)
All residual flux must be removed from the interior and exterior of the copper piping by thoroughly flushing before installation
of the Sprinkler Heads. Otherwise, residues of flux may cause corrosion and/or leakage in the sprinkler system.
INSTALLATION
The Model FR-QR, Horizontal Sidewall and Recessed Horizontal Sidewall Sprinklers 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
Ⅱ for installation of Model FR-QR 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 D2 Recessed Escutcheon.
Re-adjust the sprinkler fitting to correct the position.
Installing Procedure
Install Model FR-QR sprinklers by the steps and figures shown below. Use only D1 or D2 Recessed Escutcheons with Model
FR-QR sprinklers. Use of any other recessed escutcheon is prohibited and may void the warranty and/or approvals. Model
FR-QR sprinklers are only to be installed adjacent and perpendicular to the wall.
Step 1
For Recessed Horizontal Sidewall Sprinklers, install the Inner Ring of the D1 or D2 Recessed Escutcheon over the sprinkler
threads.
Step 2
Apply pipe-thread sealant to the threads. Begin hand-tightening the sprinkler into the sprinkler fitting in the horizontal position.
(Ref. Figure 3 and 4)
Step 3
Using the Socket FR-HⅡ 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) with the TOP of the deflector facing towards the ceiling. (Ref. Figure 5)
A 1/2" drive ratchet (not included) is required for use with the Socket FR-HⅡ.
Step 4
Remove the Protector by hand. (Ref. Figure 6)
For Recessed Horizontal Sidewall Sprinkler, slide on the Outer Ring of the D1 or D2 Recessed Escutcheon over the Sprinkler
and push the Outer Ring over the Inner Ring until its flange comes in contact with the wall. (Ref. Figure 7 and 8)
