Installation
Model RFC series sprinklers are intended to be installed in ac-
cordance with NFPA 13, NFPA 13R, or NFPA 13D, as well as the
requirements of applicable authorities having jurisdiction. Mod-
el RFC series sprinklers must not be installed in ceilings with
positive pressure in the space above. Ensure that the 4 slots in
the cup are open and unobstructed following installation. Model
RFC series sprinklers are shipped with a protective cap that
should remain on the sprinkler until installed. The protective cap
should be replaced following installation of the sprinkler and
permanently removed only when the cover plate is installed and
the sprinkler system is placed in service following construction.
Model RFC series sprinklers are installed with the Model FC
wrench. The use of any other wrench to installed Model RFC se-
ries sprinklers is not permitted and may damage the sprinkler.
Temporarily remove the protective cap during installation of the
sprinkler. Insert the Model FC wrench over the sprinkler until the
wrench engages the body. Do not wrench any other part of the
sprinkler/cup assembly. The Model FC wrench is designed to
be turned with a standard 1/2” square drive. Tighten the sprin-
kler into the fitting after applying a PTFE based thread sealant
to the sprinkler’s threads. Recommended installation torque is
8 to 18 ft-lbs (11 to 24 N-m) for 1/2” thread sprinklers and 14 to
20 ft-lbs (19 to 27 N-m) for 3/4” thread sprinklers.
Do not exceed the maximum recommended torque. Exceeding
the maximum recommended torque may cause leakage or im-
pairment of the sprinkler. Use care when inserting or removing
the wrench from the sprinkler to avoid damage to the sprinkler.
Install the cover plate by hand by pushing the cover plate into
the cup and turning the cover in the clockwise direction until it
is tight against the ceiling.
Application
Model RFC series sprinklers are intended for installation where
residential sprinklers are permitted or required by NFPA 13,
NFPA 13R, and NFPA 13D. The sprinklers are concealed pen-
dent residential sprinklers.
Model RFC 30, RFC30LL, RFC43, RFC43LL, RFC49 and RFC49
LL sprinklers are available in ordinary temperature classifica-
tion for installation where the Maximum Ceiling Temperature
does not exceed 100°F (38°C). Model RFC58 and RFC76 sprin-
klers are available in either ordinary or intermediate tempera-
ture classification for installation where the Maximum Ceiling
Temperature does not exceed 100°F (38°C) or 150°F (66°C),
respectively.

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.

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.

P/N 9999970235Maintenance
Reliable Model F1Res Sprinklers should be inspected and the
sprinkler system maintained in accordance with NFPA 25, 13,
13D, and 13R, as well as the requirements of any Authorities
Having Jurisdiction.
Prior to installation, sprinklers should remain in the original
cartons and packaging until used. This will minimize the potential
for damage to sprinklers that could cause improper operation or
non-operation.
Do not clean sprinklers with soap and water, ammonia liquid or
any other cleaning fluids. Remove dust by gentle vacuuming
without touching the sprinkler.
Replace any sprinkler which has been painted (other than factory
applied). Properly installed CCP, SWC, and SWC–2 cover plates
will have an air gap that is required for proper operation, do not
seal the gap or paint the cover plates.
Replace any sprinkler which has been damaged, where cracks
are observed in the glass bulb, or when liquid has been lost from
the glass bulb.
A stock of spare sprinklers should be maintained to allow quick
replacement of damaged or operated sprinklers.
Failure to properly maintain sprinklers may result in inadvertent
operation or non-operation during a fire event.

RD13
Residential Riser
Description
The RD13 Riser (with NPT connectors) is constructed from Listed
CPVC products suitable for fire sprinkler services subject to the
limitations and installation requirements of Flameguard® CPVC pipe
and Spears® CPVC fittings. The RD13 Riser incorporates a VSR-SG
flow switch, gauge, and drain/test valve. The VSR-SG flow switch is
equipped with union connection to facilitate the installation and removal
of the switch in confined spaces.
Installation
1. Using appropriate sealant, thread the female adapter on to the
main water supply. Then glue the riser assembly to the female
adapter. Pipe the drain connection to an adequate drain location
capable of handling the drain discharge. The riser can be mounted
in the horizontal or vertical position. Direction of flow is indicated
in Fig. 1. The waterflow switch must be located on the top or
on the side of the pipe when installed in the horizontal position.
This will prevent debris from entering the throat of the waterflow
switch which could interfere with proper operation.
2. Following CPVC manufacturer’s instructions for preparation and
gluing of CPVC piping systems, glue the main riser to the main
supply line for the sprinkler heads. NOTE: All glued connections
must be completed and cured before the flowswitch is installed.
(Continued on page 2).
Features
• Pre-assembled and pressure tested
• Available in 1”,1 1/4”, 1 1/2”, & 2” nominal pipe size models
• Female adapter ships loose so riser can be installed in a
confined space
• Fits in standard 2X4 construction walls
Specifications subject to change without notice
Do not over-tighten the union nut, hand tighten only. Use of a
wrench may cause damage to the union nut.
• Installation must be performed by qualified personnel and in
accordance with all national and local codes and ordinances.
• Shock hazard. Disconnect power source before servicing. Serious
injury or death could result.
• Risk of explosion. Not for use in hazardous locations. Serious
injury or death could result.

Maintenance
The VSR-SG waterflow switch should provide years of trouble-free service. The retard and switch assembly are easily field replaceable. In the
unlikely event that either component does not perform properly, please order replacement retard switch assembly stock number 1029030. There is no
maintenance required, only periodic testing and inspection..
Removal
• To prevent accidental water damage, all control valves should be shut tight and the system completely drained before waterflow detectors are removed or
replaced.
• Turn off electrical power to the detector, then disconnect wiring.
• Loosen nut on union fitting.
• Lift detector clear of pipe.
Retard Adjustment
The delay can be adjusted by rotating the retard adjustment knob from 0
to the max setting (60-90 seconds). The time delay should be set at the
minimum required to prevent false alarms.
Important:
The paddles have raised lettering that show the pipe size and the TEE
manufacturer they are to be used with. The proper paddle must be used.
The paddle must be properly attached and the screw that holds the paddle
must be securely tightened.
Fig 1
Installation (Continued)
3. A thread sealant shall be used in making threaded connections. Teflon® thread tape is the recommended sealant. Some thread sealants other
than Teflon thread tape contain solvents or other materials that may be damaging to CPVC. For other types of thread sealants, which have been
specifically investigated and confirmed to be “System Compatible”, refer to www.spearsmfg.com. Attach gauge to riser. Apply Teflon® tape to
male fitting of gauge only. See Fig 1.
4. Check to make sure the proper paddle is installed on the switch. (Paddle size must match the riser pipe size and Tee manufacture.)
5. Install the flow switch to the RD13 Riser. Verify that the o-ring is properly positioned in its groove. Hand tighten the nut to the union after
orienting the flow switch in the appropriate direction to detect waterflow. The paddle must not rub the inside of the Tee or bind in any way. The
stem should move freely when operated by hand. See Fig. 1. NOTE: Do not leave switch cover off for an extended period of time.
6. The side of flow switch must be perpendicular with the riser piping. See Fig. 3.
Testing
The frequency of inspection and testing for the Model VSR-SG and its associated protective monitoring system, should be in accordance with applicable
Codes and Standards and/or the authority having jurisdiction (manufacturer recommends quarterly or more frequently.) If provided, the inspector’s
test valve (usually located at the end of the most remote branch line) should be used for test purposes. If there is no remote inspection test connection;
a short length of hose may be connected to the discharge of the 1” drain line valve, or if the drain line is connected to a drain such as a slop sink or
storm drain that will sufficiently handle the discharge of the main drain valve. The drain valve can be used to test the operation of the VSR-SG switch.
A minimum flow of 10 GPM (38 LPM) is required to activate this switch. An orifice equal to the smallest sprinkler head orifice used in the system shall
be attached to the drain line for testing purposes.
