General
Model H 1½” (40mm) Deluge Riser incorporates a solenoid
operated diaphragm type valve as the primary valve in deluge,
preaction, or special types of fire protection systems.
The valve is easily reset by external means which eliminates
the need for removing the cover.
The trim is factory assembled for every Model H Deluge Ris-
er. This trim provides valve supervising and waterflow alarm
electric connections, pressure gauges, and system draining
provisions.
Actuation by solenoid enables a full range of electrical detec-
tors to be used for remote sensing.
Operation
Model H 1½” (40mm) Deluge Riser employs a quick opening
hydraulically operated, diaphragm actuated solenoid valve.
De-energized: supply pressure is retained at the solenoid
valve inlet. Flow through the valve is prevented by a plunger
closing off the diaphragm pilot orifice and a diaphragm sealing
against the main orifice.
Energized: the plunger is lifted off the pilot orifice and vents
the pressure behind the diaphragm. The venting creates a
pressure imbalance across the diaphragm, which causes the
diaphragm to open the main orifice allowing flow through the
solenoid valve.
Once the solenoid valve has opened, water flows from the
supply through the Deluge Riser into the piping system and to
the alarm initiating water flow pressure switch.
After system shutdown and draining, the Deluge Riser is eas-
ily reset, without special tools, by first restoring detection devic-
es to the ready condition. Once the detection system is ready,
the releasing control panel can be reset which automatically
resets the solenoid valve. Next, the water supply pressure can
be restored and the Deluge Riser will be reset. The external re-
set feature of the Model H 1½” (40mm) Deluge Riser provides
a means for simple, economical system testing which is one
essential facet of a good maintenance program.

Installation
Model H 1½” (40mm) Deluge Riser Assembly is factory as-
sembled as illustrated in Figure 1. The only piping connections
required at the time of installation are an appropriate water sup-
ply connection, the system piping connection and a ¾” NPT
(R¾) drain line connection. Installation is vertical as illustrated.
Electrical connections are required from a releasing control
panel to the solenoid valve, supply water control valve super-
vising switch, and the water flow alarm pressure switch. Refer
to Bulletin 700 for further instructions when making these con-
nections to the Potter PFC-4410-RC Releasing/Control Panel
used with Reliable Special Hazards & Special Systems. Fea-
tures and options available for Electrical Deluge and Preaction
Systems, including fire detection means, are described in Bul-
letin 700.
Resetting Deluge Riser Assembly
Refer to Figures 1 & 2
Close the control valve, Item 1.
Open drain valve, Item 3, and emergency release
station, Item 2, and drain system.
Open all drain valves and vents at low points through-
out the system, closing them when flow of water has
stopped.
Inspect and replace any portion of the detection sys-
tem subjected to fire conditions.
Electric actuation - open the solenoid valve, Item 4, by
operating a detector or an electric manual emergen-
cy station. After residual water has drained through
the solenoid valve, cause it to close by resetting the
detector or manual station; and thereafter, the Re-
leasing/Control Panel. Refer to Bulletin 700, “Special
Hazards & Special Systems” for details.
Close the emergency releasing station, Item 2. Open
slightly the control valve, closing drain valve, Item
3, when water flows from it. Close the control valve
again and observe supply pressure gauge, Item 6, for
any drop in pressure. No pressure drop confirms all
valves are leak tight and the Riser Assembly is prop-
erly set then the control valve, Item 1, is reopened.
Check that the control valve is fully open, and prop-
erly supervised.
Inspection and Testing
Refer to Figures 1 & 2
Water supply - be sure the valve, Item 1, controlling
water supply to the Deluge Riser is open fully and
properly supervised in this position.
Other valves - check that valves, Items 2 , 3 and 37,
are closed and not leaking, by performing Step 6
above.
The automatic drain valve, Item 38, monitors internal
leakage. Push in on its plunger to be sure ball check
is off its seat. If no water appears, the Deluge Riser
Assembly is leak tight.

Operation test - Open the solenoid valve, Item 4, us-
ing the procedure in Step 5 above. Note: Operation
test will cause full flow into the deluge system unless
the control valve is throttled or closed prior to per-
forming this test.
Reset the Riser Assembly (Steps 1-7 above).
Testing Detection System Without Flow Through
Deluge Riser
Close the control valve, Item 1.
Operate detection system - refer to Bulletin 700.
Operation of the detection system must result in a
sudden drop of water pressure indicated on supply
pressure gauge, item 6. When gauge drops to zero,
open drain valve until all water above the control
valve drains away.
Reset detection system - reverse operations per-
formed in Step 2 above. The solenoid valve closes
when the Releasing/Control Panel is reset.
Reset the Riser Assembly (Steps 1-7 above).
Maintenance
Reliable Deluge Riser Assemblies and associated equip-
ment shall periodically be given a thorough inspection and
test. NFPA 25 provides minimum requirements for inspection,
testing and maintenance. The Deluge Riser should be tested,
operated, cleaned and inspected at least annually and parts
replaced as required.
Maintenance Procedures
Refer to Figures 2 & 3
Steady water flow into the system, as evidenced by dripping
at the automatic drain valve, is caused by water leaking past
the solenoid valve or past the emergency station valve. To lo-
cate and correct the trouble, proceed as follows:
Maintenance of Solenoid Valve
Caution: Do not expose plastic or elastomeric ma-
terials to any type of commercial cleaning
fluid. Parts should be cleaned with a mild

ed in each kit are marked with an asterisk (*). See ex-
ploded view, Figure 3.
Maintenance of Emergency Station Valve
This valve, Item 2, is not field serviceable. In the
event that leakage is occurring it must by replaced
with a new manual emergency releasing station. Re-
placement is made by removing the coupling, Item
33 and loosening the union, Item 46, and then un-
screwing the segment of piping which begins with
nipple, Item 16, at the inlet to the valve. When order-
ing replacement valve, Item 2, also order two clamp
rings, Item 22, for remounting the nameplate base,
Item 36. Make certain both new clamp rings have
been slipped onto the nipple, Item 16, above the
valve before the new valve is attached to this nipple.
After all piping is reconnected, reposition the name-
plate, as shown, and tighten the new clamp rings
over the two nameplate tabs using crimping pliers to
draw the bands tight.

SOLENOID VALVE INSPECTIONS, TESTS AND MAINTENANCE
WARNING: THE OWNER IS RESPONSIBLE FOR MAINTAINING THE FIRE PROTECTION SYSTEM IN PROPER
OPERATING CONDITION. ANY SYSTEM MAINTENANCE OR TESTING THAT INVOLVES PLACING A CONTROL
VALVE OR DETECTION SYSTEM OUT OF SERVICE MAY ELIMINATE THE FIRE PROTECTION OF THAT SYS-
TEM. PRIOR TO PROCEEDING, NOTIFY ALL AUTHORITIES HAVING JURISDICTION. CONSIDERATION SHOULD
BE GIVEN TO EMPLOYMENT OF A FIRE PATROL IN THE AFFECTED AREA.
WARNING: PRIOR TO OPERATING THE SOLENOID VALVE, BE SURE TO CLOSE THE SYSTEM CONTROL
VALVE TO AVOID UNINTENTIONAL OPERATION OF THE DELUGE VALVE
Inspections: It is imperative that the system be inspected and tested in accordance with NFPA 25 on a regular
basis. The frequency of the inspections may vary due to contaminated water supplies, corrosive water supplies, or
corrosive atmospheres. In addition, the alarm devices, detection systems, or other connected trim may require a
more frequent schedule. Refer to the system description and applicable codes for minimum requirements.
The valve must be inspected at least monthly for cracks, corrosion, leakage, etc., and cleaned, repaired, or re-
placed, or replaced as necessary.
If leakage is suspected through the solenoid valve, the valve diaphragms and seats should be inspected and if
necessary, repaired or replaced.
WARNING: CLOSE SYSTEM CONTROL VALVE, TURN OFF POWER SUPPLY, AND DEPRESSURIZE VALVE
BEFORE DISASSEMBLING VALVE. IT IS NOT NECESSARY TO REMOVE THE VALVE FROM THE PIPE LINE TO
MAKE INSPECTIONS.
When lubricating valve components, use high grade silicone grease (Dow Corning® 111 Compound Lubricant or
equal).
When reassembling, tighten parts to torque values indicated in the manufacturer’s maintenance instructions
(packed with valve).
After maintenance is completed, operate the valve a few times to be sure of proper operation. A metallic “click”
signifies the solenoid is operating.
All service must be performed by qualified personnel. Upon completion of inspections or replacement of the valve,
the entire system must be checked for proper operation. See appropriate system description and testing instruc-
tions for additional information.
