Installation
Models F1Res sprinklers are to be installed as shown in this
bulletin. Model F1, F2, FV, and FP recessed escutcheons are
the only recessed escutcheons to be used with Model F1Res
sprinklers. Not all F1Res sprinklers may be used with all
recessed escutcheons offered. Confirm listing of escutcheon
type for use with individual sprinklers. Use of any other
recessed escutcheon will void all approvals and warranties.
For installing Model F1Res sprinklers, use only the Model
W2 sprinkler Wrench; for installing Models F1Res Recessed
Pendent, Sidewall, Conical Concealed Pendent (CCP), and
Sidewall Concealed (SWC and SWC–2) sprinklers use only the
Model W4 sprinkler wrench. Use of wrenches other than those
specified may damage these sprinklers.
Installation of F1Res sprinklers in a wall or ceiling will require
a hole diameter of 2-1/4” (57 mm) for F1 or F2 recessed
escutcheons; or 2-5/8” (67 mm) for FP recessed escutcheons,
CCP, SWC, and SWC–2 cover plates.
Install F1Res HSW sprinklers with a ceiling to deflector
distance that complies with the hydraulic design criteria tables
in this bulletin. The flow arrow on deflector must point away
from near wall and “Top” marking must face the ceiling.
A ‘leak tight” sprinkler joint can be obtained with the following
torque:
• 1/2” NPT and ISO7-1R1/2: 8-18 ft-lbs (11 – 24 N-m)
• 3/4” NPT and ISO7-1R3/4: 14-20 ft-lbs (19 – 27 N-m)
Do not tighten sprinklers over maximum recommended torque.
This may cause leakage or impairment of the sprinklers.
Do not install any glass bulb sprinklers where the bulb is
cracked or there is a loss of liquid from the bulb.
Glass bulb sprinklers have orange bulb protectors to minimize
bulb damage during shipping, handling and installation.
Remove this protection at the time the sprinkler system is
placed in service. Removal of the protectors before this time
may leave the bulb vulnerable to damage. RASCO wrenches
are designed to install sprinklers when protectors are in place.
Remove protectors by undoing the clasp by hand. Do not use
tools to remove the protectors.

Finishes
The Model W4 wrench includes two sets of jaws. One set of
jaws is equivalent to a Model GFR2 wrench and the other set
of jaws is equivalent to a Model W1 wrench. Use the smallest
of the two sets of jaws that will fit on the sprinkler’s wrench
flats. The Model W4 wrench is used in conjunction with the
installer’s nominal 1/2” square drive ratchet and nominal 5”
(125mm) long extension (not provided) as shown in Figure 13.
