I. SYSTEM DESCRIPTION
The Viking ESFR Pre-Primed Single Interlock Preaction Cold Storage System is a fixed fire protection system designed for installation in refrigerated, cold storage and unheated warehouse applications with rack storage of Class II commodity on wood pallets. This system effectively prevents frost plugs associated with systems that supervise the piping network with air. The single interlock preaction sys­tem piping network is supervised with a propylene glycol solution. When using this system for single-, double- and multiple-row rack storage, Viking K25.2 ESFR sprinklers are used at the ceiling only and no in-rack sprinklers are required.
1. System Considerations
All materials installed on the system shall be compatible with propylene glycol solution.
• Where the minimum temperature in the area being protected is 8 °F (-13.3 °C) or above,
• Firefighter Eliminator C 35% percent by volume propylene glycol factory premixed solution must be used.
Where the minimum temperature in the area is between 8 °F (-13.3 °C) and -21 °F (-29.4 °C),
• firefighter Eliminator F 50% percent by volume propylene glycol factory premixed solution must be used.
The minimum ambient temperature where the system can be used is -21 °F (-29.4 °C). This
• is not an average temperature; it is the lowest temperature within the area.
The system piping configuration shall be designed in a tree configuration only. The
•
mains and branch lines should not be looped together. Grid systems are NOT allowed. The piping system shall be pitched to drain completely. The branch lines shall be pitched at ¼” per 10 ft (4 mm/m) run of pipe and the mains shall be pitched ½” per 10 ft (4 mm/m) run of pipe.
2. System Makeup
Each Viking ESFR Pre-Primed Single Interlock Preaction Cold Storage System requires the fol­lowing components for proper operation:
Water Supply Control Valve
• Deluge Valve with Conventional Deluge Valve Trim
• Electric Release Trim with Solenoid Valve
•

II. SYSTEM DESIGN
1. Hydraulic Calculations
Two hydraulic calculations are required for the system: The first calculation shall be with the 12 Viking VK510 K25.2 ESFR’s assuming they are flowing
water. This calculation shall include 4 sprinklers on the 3 most hydraulically remote branch lines discharging at the minimum design pressure for the system. This calculation shall use the Hazen Williams formula. See examples in Figures 3 & 4.
The second calculation shall include 6 Viking VK510 K25.2 ESFR’s flowing propylene glycol solution. The calculation shall include 4 sprinklers on the most hydraulically remote branch line and 2 sprinklers on the second most hydraulically remote branch line discharging at the minimum design pressure required for the system. This calculation shall use the Darcy-Weisbach formula. See examples in Figures 6-8.
Full-scale fire testing has demonstrated that the propylene glycol solution will be expelled from the system by the time 6 sprinklers are operating in a fire condition. The 6-head sprinkler calcula­tion using the Darcy-Weisbach formula is used to ensure that the piping has been sized properly and the water supply is adequate for the more viscous liquid. Because the propylene glycol will have a dramatically different viscosity at the colder temperature expected in this application, fric­tion loss through the piping network will be significantly higher than water.
When conducting hydraulic calculations, a good rule of thumb is to increase pipe size when friction loss has reached .3 PSI per foot of pipe. By setting up the spreadsheet described in Appendix B, a quick estimation of the difference in friction loss will assist in determining if the desired pipe size will be adequate. The final pipe sizes will need to be confirmed through the actual hydraulic calculations.

Typically, when a partial branch line is required in the hydraulic calculations, the sprinklers closer to the cross main will be used, as shown above. The calculation of the closer sprinklers will result in less friction loss and a smaller pressure demand on the branch line. At the cross main, a K factor for the branch lines will need to be determined. The lower pressure requirement will result in a larger K fac­tor and thus require more water on the partial branch line, typically making the closer sprinklers more demanding.

Darcy-Weisbach Method for Calculating Friction in Piping:
Most hydraulic calculation software used in the sprinkler industry today has the option for conducting the piping friction loss calculations with the Darcy-Weisbach method. The reason for conducting the additional 6 sprinkler head calculation is to verify that the available water supply pressure is adequate for the initial discharge of propylene glycol solution. The example calculations provided in Figures 6­8 illustrate the difference in results that can occur when calculating for the more viscous propylene glycol solution versus the standard Hazen-Williams calculation for water illustrated in Figures 3-4. For those not familiar with the Darcy-Weisbach method below is the basic procedure that is used to conduct the calculation. This is intended only to provide the designer with an understanding of the concepts of the method. It is not practical that the calculation be done by hand as this would be much too time consuming and subject to potential errors.
2
The Darcy-Weisbach Formula as found in most text is written as: h= (f) (l) (v) h=friction loss (ft of head) f=friction factor (from Moody Diagram-Figure 10) l=length of pipe (ft) v=velocity (ft/sec) d=diameter of pipe (ft)
2
g=gravitational constant (32.2 ft/sec
)
/ (d) (2) (g)
This formula can be rearranged and simplified to:
2/d5
When the calculated Reynolds Number (Re) is >2000 =0.000216 fLρQ When the calculated Reynolds Number (Re) is <2000 =0.000273 μLQ/d
=Friction Loss (psi)
4
=Friction Loss (psi) Where: Re=50.6Qρ/dμ Q=flow (gpm)
3
ρ=density (lbs/ft
) d=internal pipe diameter (in) D=internal pipe diameter (ft) L=pipe length (ft)
μ=dynamic viscosity (cps) ε= .00033 for steel pipe
f=friction factor, If Re > 2000, use Moody Diagram (Figure 10). If Re < 2000, f = 64/Re. Procedure:
1. Calculate Reynolds Number (Re) = 50.6Qρ/dμ
2. Calculate relative roughness of pipe = ε/D ε= .00033 (ft) D=internal pipe diameter (ft)
3. Use Moody Diagram (Figure 10) to find “f” if Re > 2000. If Re < 2000, f = 64/Re.
4. Use fiction loss in hydraulic calculation.

2. Determining the Required Volume of Propylene Glycol
The system design area (12 sprinklers: 4 on each of the 3 hydraulically most remote branch lines) and bulk main to the primary Easy Riser® Check Valve (lines in bold) at the base of the riser is limited to a total volume of 1,100 gallons.* Additional mains and sprinkler lines attached to the sprinkler system, but not in the direct path to the base of the riser, do not need to be considered in the volume restriction.
The actual volume of propylene glycol solution for the sprinkler system is determined by adding all the sprinkler piping together. Additional propylene glycol is added to this total for the CS-1 Tank and supply lines to the riser.

* Note: Based on the installation history of this system, systems near 25,000 ft2 in area, with long runs on feed main, typically begin to approach the 1,100 gallon restriction, or begin to demand excessive pressures in the Darcy-Weisbach calculation. This history can be used as an estimating tool, however, the actual system volume must be calculated.

4. Designing the Detection System
The detection system shall consist of low temperature “spot” type heat detectors, air sampling smoke detection or beam smoke detection. Linear heat detection is not suitable for this system and shall not be used.
Viking does not have a preferred manufacturer of initiating devices. Spot heat detectors are typically not subject to compatibility issues with the release control panel. Viking considers all listed and approved spot type heat detectors that the manufacturer determines is appropriate for cold storage applications acceptable. The detection system shall be designed to allow the heat detectors to operate prior to the Viking K25.2 ESFR sprinklers by selecting a lower temperature rating and RTI for the heat detector. (NFPA 13 defines an ESFR Sprinkler as having a thermal element with an RTI of 50 (meters sec.½) or less.) The heat detector manufacturer shall be con­tacted for the heat detector RTI information.
Air sampling systems are also considered acceptable for activation of the ESFR Cold Storage System, and should be designed in accordance with the manufacturer’s instructions.
The detection system shall be designed in accordance with the requirements of NFPA 72.
5.6.2.3 Marking: Heat-sensing fire detectors shall be marked with their listed operating tempera­ture. Spot-type heat detectors shall also be marked with their RTI (response time index). The RTI marking requirements shall have an effective date of July 1, 2008.
5.6.5.5.1 On ceilings 10 ft to 30 ft (3 m to 9.1 m) high, heat detector linear spacing shall be reduced in accordance with Table 5.6.5.5.1 prior to any additional reductions for beams, joists, or slope, where applicable.
5.6.5.5.2 The minimum spacing of heat detectors shall not be required to be less than 0.4 times the height of the ceiling.

2. Grooved Couplings
In order to prevent leaks and preserve the antifreeze solution, it is imperative that grooved pipe ends are smooth, round, and free of burrs, flat spots, and weld seam imperfections. Also, pipes should be capped to prevent contaminant during shipping, storage, etc. Verify that any gasket materials used in couplings, etc. are compatible with the antifreeze solution. Refer to the anti­freeze solution technical data page.
Where grooved couplings are used in the system, “flush seal” gasket, low temperature EPDM rubber and lube are required. Gaskets: grade “E” EPDM, NSF-61 Certified, -40 °F to 230 °F (ser­vice temperature range) (-40 °F to 110 °F) recommended for water service, diluted acids, alkalys solutions, oil-free air and many chemical services. GRUVLOK Xtrema Lubricant is required for freezer applications. In order to pervent leaks and preserve the antifreeze solution, the grooved pipe ends must be smooth, round, and free of burrs.

NOTES: An alarm test connection is provided on the deluge valve trim. When testing the alarm,
the downstream isolation valve (illustrated in Figure 30) and antifreeze isolation valve (illus­trated in Figure 33) must be shut before opening the test valve.
This is a precaution in case the deluge valve would inadvertently operate due to problems in the trim components and cause water to enter the system causing possible contamination of antifreeze. After testing of the alarm, restore the control valves to their normal operating posi­tion and open the antifreeze supply valve.
A. Water Flow Pressure Switches (PS-10)
Each system requires 2 water flow pressure switches that transmit an alarm after the system has activated.
The Double Switch (PS-10-2A) Water Flow Pressure Switch (Switch #1) is installed on the deluge valve conventional trim. In addition to transmitting an alarm signal, Switch #1 is wired in conjunction with digital Switch #5 to prevent the solenoid valve on the CS-1 Tank and Pump Unit from opening when the water flow switch is activated. This prevents propylene glycol from entering the system when water is flowing.
The Single Switch (PS-10-1A) Water Flow Pressure Switch (Switch #2) is installed on the del­uge valve conventional trim. Switch #2 is wired in conjunction with Digital Pressure Switch #4 in order to prevent the operation of the APCS during system operation.

A. Cold Storage Trim with Automatic Pressure Control System
In cold storage areas where temperatures can fluctuate, over-pressurization of the system can occur. The Automatic Pressure Control System (APCS) is used to prevent this from occurring. The pressure relief valve (PRV) operates when the set point of 205 PSI (14.1 Bar) is reached. Normal operation of the PRV includes operation at 90-105% of the set point and closing at 80% of the set point. The Automatic Pressure Control System (APCS) is designed to maintain a safe operating pressure below the set point of the PRV and above the maximum residual or static pressure of water supply system or maximum set pressure of the system pressure switch. The Automatic Pressure Control Trim is included with the Easy Riser® Cold Storage Trim and installed on the primary Easy Riser® Check Valve.
The APCS includes an electronic digital pressure switch that includes a normally open SPST switch that is set to close at a pressure below the PRV set point and open above the static water supply or shut-off pressure of the riser system. A waterflow switch is to be installed on the non-interruptible alarm port of the conventional trim on the deluge valve. A normally closed solenoid valve is to be installed on the cold storage trim at the ¼” connection provided. A 115­220 VAC, (50 or 60 Hz) GFI protected electrical power supply is to be provided directly to the switch.
During normal operating condition, the propylene glycol within the system piping network is pressurized to 50 PSI (3.45 Bar). The APCS uses a digital pressure switch (Switch #4) in conjunction with a 120 VAC solenoid (Switch #2) to relieve pressure from the system when the pressure exceeds 85 PSI (5.86 Bar). The digital pressure switch (#4) comes factory set to operate and energize the solenoid (#2) at 85 PSI (5.86 Bar). The digital pressure switch will change state and remove power from the solenoid (#2) at 75 PSI (5.17 Bar).
The digital pressure switch (#4) and solenoid (#2) are wired and powered from a dedicated 115-220 VAC (50 or 60 Hz) GFI protected power supply and routed through a water flow pres­sure switch (#2) as shown in Figure 39. These devices operate independently and are not connected to either the release control panel or the CS-1 tank and pump unit. The normally closed water flow pressure switch prevents the APCS from operating under normal water flow conditions.
The pressure switch on the deluge valve will make the APCS inoperable when the detection system causes the deluge valve to open. This prevents water flow from the APCS.
1. Supervisory Pressure Switch (PS-40)
The Automatic Pressure Control System includes a PS-40 Supervisory Pressure Switch that is installed on the primary Easy Riser the appropriate supervisory circuit on the Viking VFR­400 to annunciate a supervisory signal upon a low pressure condition with the propylene glycol. It is recommended to set the switch to activate at 30 PSI (2.07 Bar).

B. Technical Data
NOTE: The pressure switch (#6) on the CS-1 pump unit is factory set at cut-in pressure and cut-out pressure. The pressure downstream of the Easy Riser® Check Valve is main­tained at 50 PSI Max to 35 PSI Min. (3.4 bar - 2.4 bar) by digital pressure switch (#5).
C. Installation
1. Handling
Move the CS-1 on the shipping pallet as close to the final location as possible. Always lift the unit from underneath. Never lift the unit when it is full of liquid. Personal injury and/or equipment damage could result.
Ensure that all equipment used to lift the CS-1 is capable of lifting the weight. Nylon straps and soft rigging devices should be used whenever possible to protect the components and finish.
If the unit is being transported overhead, be sure that all personnel are alerted and safety procedures are followed.
2. Location
Install the CS-1 indoors in a clean, dry , non-corrosive environment. This equipment is not to be installed outdoors exposed to the weather. Position the CS-1 in an upright position on a solid, level, vibration-free surface capable of supporting the weight of the unit and liquid in the tank. Bolt the unit to the floor using the bolt holes provided in the frame. Always shim the unit level before bolting it to the floor. Install the CS-1 in a protected, well-ventilated area where the ambient temperatures are between 40 °F and 100 °F (4.4 °C to 37.8 °C).
Locate the CS-1 to allow access to supply and discharge connections. Clearance around the unit should be at least 24” (610 mm) on all sides for maintenance. Some jurisdictions require specific clearances around equipment. Check with all local Authorities to ensure compliance with applicable state, local, and national codes.
3. Piping and Connections
A slight downward slope from the supply container to the CS-1 supply valve connection is recommended to maintain positive head on the pump inlet.
Always use a backup wrench when making piping connections to avoid damage to the unit’s piping.
Size piping between the CS-1 and the system 3/4” or greater to minimize pressure drop. Clean black pipe is acceptable. Too small of a line size restricts pump flow and
causes excessive back pressure, lowering capacity when filling the system. Lower capac­ity while filling the system requires longer fill times. If the pump stops before obtaining set system pressure, the CS-1 setting will require being increased. The sprinkler system must contain air vent/bleed valves at all local high points. These are used to let air out of the system while filling with antifreeze. Consult the system instructions for specifics.
Individual check valves and isolation valves are required for each system. This allows sys­tem maintenance without disturbing other systems the CS-1 is connected to.
Piping and/or hoses from the antifreeze supply containers to the unit should be sloped downhill slightly to provide positive head on the pump suction connection. These lines should be as large as possible and as short as possible to provide unrestricted flow to the

pump while filling. A separate shut-off valve in the supply line is required. Unit piping is copper, brass and bronze. An aluminum manifold is included for mounting
multiple system solenoids. Use dielectric unions to isolate copper piping from iron piping, if used, to reduce the possibility of electrolytic action on pipes and other components.
All pipes should be de-burred and threaded to a proper depth and length before installation. Threads should be inspected for cleanliness and depth of cut. Good quality pipe compound should be used to ensure a good, leak-tight fit of piping components.
NOTE: Pipe must be supported separately from the CS-1. At no time should the CS-1 support the weight or load of the pipe. Acceptable pipe mounting devices would be unistrut supports anchored to walls, hangers suspended from ceilings, or pedestals mounted from the floor. Be sure all pipe installation conforms to all building and fire codes.
4. Electrical Connections
SERIOUS PERSONAL INJURY AND DAMAGE TO THE CS-1 WILL OCCUR IF IT IS CONNECTED TO A POWER SOURCE OTHER THAN THE VOLTAGE LISTED ON THE DA T A TAG. THE MANUFACTURER IS NOT LIABLE FOR DAMAGE DUE TO IMPROPER WIRING, PROTECTION, OR ELECTRICAL SERVICE INSTALLATION.
When installing electrical service to this machine, comply with the National Electric Code as well as state and local building codes.
Failure to install the proper electrical protection can result in personal injury , fire, equipment damage or death. The manufacturer is not responsible for damage or injury caused by lack of or improperly installed electrical protection.
Electrical connection to the unit is made in the control enclosure. Connect appropriate supply power to the terminals provided. The supply wire must be of adequate size and no other equipment should be connected to the same circuit. An arrow on the pump indicates the correct direction of rotation. If the pump rotates in the opposite direction, reverse the rotation of the motor. Interchanging any two incoming 3-phase supply wires reverses rota­tion of 3-phase motors.
WARNING: Operating the pump in the wrong direction may damage the pump. Verify pump rotation is correct before placing the unit in service. Make sure there is liquid on the suction side of the pump before checking rotation.
Connect system inputs to the proper terminals in the CS-1 control enclosure. Each system pressure switch and alarm flow switch are connected as shown on the electrical sche­matic.
NOTE: All system inputs must be connected before operating the unit. System valves will not respond unless the system pressure switch and flow alarm switch are connected correctly.
5. Start-Up
The following points must be verified before putting the unit into service. Correct any dis­crepancies before operating the unit:
The unit is bolted to a firm level surface.
• Area temperature will always remain between 40 °F and 100 °F (4.4 °C to 37.8 °C).

D. CS-1 Control Scheme
1. Pump Operation
The pressure switch mounted on the CS-1 controls pump operation. When the pressure at the CS-1 drops, the pump will turn on until the pressure at the CS-1 rises above a set level. In “Automatic” mode, pump operation is inhibited if the level of liquid in the unit’s storage tank drops below the level switch height.
In “Manual” mode, the pump operates when CS-1 pressure drops, a system valve is se­lected, if that system pressure is not met, and there is no alarm condition. The pump can also fill the tank in Manual mode. For tank filling, the level switch position is not used and the operator must start and stop the pump, using the “Man” position of the Man-Off-Auto Switch on the control panel.
In Automatic mode, there is a 10-minute time delay between pump operations. After the 10­minute delay, the pump operates if the CS-1 pressure drops and tank fluid level is above the level switch height. When the pump shuts off, the 10-minute timer starts again and the pump will not operate until 10 minutes is complete.
2. System Solenoid Valve Operation
Each system (riser) pressure switch and alarm pressure switch contacts are connected in series to one input on the PLC. The system pressure switch opens on falling pressure. The alarm pressure switch normally closed contacts are used and open in the alarm condi­tion.
In Automatic mode, each system solenoid valve opens if its system pressure drops to a low-pressure condition and there is no alarm pressure signal. In manual mode, each system valve is selected by means of two selector switches and the solenoid valve opens as long as system pressure is below the set-point value and there is no system alarm.* Note: To operate in manual mode, all switches must be wired.
3. Level Switch Relay Coil Operation
The level switch relay coil is energized when the tank level is above the level switch height. This is when tank level is satisfied. The switch relay coil de-energizes when tank level drops to the level switch height, at low tank level.
E. Filling the Reservoir Tank
The CS-1 has been designed to fill the reservoir tank using either of two methods: gravity fill or pumped fill. NOTE: This is NOT a self-priming pump. Manually prime or fill the reservoir for prime.
*NOTE: Never leave the unit unattended when filling the system or tank. Running the pump dry, without liquid, will damage pump seals and possibly damage pump impel­ler.
Follow the steps below:
1. Gravity Fill:
Turn off and isolate the electrical supply to the unit.
1. Close Supply Isolation valve.

Connect the antifreeze supply container to the supply isolation valve. A flexible hose
3. may be used, but must not restrict the flow from the supply container to the valve. An additional isolation valve must be installed in the line between the supply container and unit’s supply isolation valve.
Open the shut off valve on the supply container and supply isolation valve on the
4. CS-1.
Open the pump suction isolation valve and allow liquid to enter the reservoir tank. If
5. there is enough liquid in the supply container, the tank may be filled completely using this method. The tank is full when the liquid level rises to the top of the straight sec­tion of the tank.
2. Pump Assist Fill:
If there is not sufficient liquid in the supply container to fill the tank or the tank fills too slowly , the pump on the CS-1 may be manually operated to speed up this process. Follow steps 1 to 4 above and 2 to 5 below to fill the storage tank using the pump. A slight downward slope from the supply container to the valve connection is required to prime the pump and maintain positive head on the pump inlet. Always use a backup wrench when making piping connections to avoid damage to the unit’s piping.
1.
Close the tank discharge isolation valve and open the tank fill isolation valve.
2.
With the CS-1 “OFF-ON” switch in the “OFF” position, turn on power supply to the unit.
3.
Position switches “A” and “B” in the center/off position. Switch the “Man-O-AUTO” switch on the unit control panel to “Man” and the “OFF-ON” switch to “ON”. Liquid will begin to fill the storage tank at the fill connection.
4.
Be careful to observe the liquid level to prevent overfilling. When the liquid level reaches the top of the straight section of tank, switch the unit’s “Man-O-AUTO” switch to “O”.
5.
Close the liquid supply isolation and tank fill isolation valves. Open the tank discharge isolation valve.
F. Filling Systems
A suitable portable pump can be utilized to fill the system. (The CS-1 pump can be used for filling the system initially at 15 GPM (56 l/min) to 100 ft head pressure or system static pres­sure. However, it is a less efficient pump for filling the system because of the duration of time required to do so. To fill the system, the system solenoid on the CS-1 is connected to the liquid supply isolation valve of the Easy Riser® Check Valve for that system. All pressure switches must be installed and set. The system to be filled is selected using two toggle switches on the CS-1 control enclosure. Antifreeze from the supply is pumped to the system piping. Pump op­eration is manually controlled during the fill process. The CS-1 pump is to be utilized to bring the solution to maintenance pressure, and is designed to maintain system pressure once the system is initially filled. Appropriate vent/bleed valves must be installed on each system’s pip­ing at all local high points to allow air to escape while liquid fills the system.
NOTE: Never leave the unit unattended when filling the system. Running the pump dry, without liquid, will damage pump seals and possibly damage the pump impeller.

Follow the steps below:
Turn off and isolate the electrical supply to the unit.
1. Close the liquid supply valve and Tank Fill isolation valves.
2. If not already connected to fill the storage tank, connect the antifreeze supply container
3. to the liquid supply valve. A flexible hose may be used, but must not restrict the flow from the supply container to the valve. An additional isolation valve must be installed in the line between the supply container and unit’s liquid supply valve. A slight downward slope from the supply container to the unit’s valve connection is required to prime the pump and maintain positive head on pump inlet. Always use a backup wrench when making piping connections to avoid damage to the unit’s piping. Open the shut-off valve on the supply container and liquid supply valve on the CS-1.
4. Open high-point vent/bleed valves on the system.
5. Select system to be filled using switches “A” and “B”. Use Table 14 or the table on the
6. CS-1 Panel to determine switch “A” and “B” position. With the CS-1’s “OFF-ON” switch in the “OFF” position, turn on the power supply to the
7. unit. Switch the “Man-O-AUTO” switch on the unit control panel to “Man”. Turn the “Off-On”
8. switch to “ON”. Liquid will begin to fill the selected system. As the system fills, monitor the system vent/bleed valves. Close each valve when liquid
9. leaks from it. When the liquid leaks from the uppermost vent/bleed valve, close the vent valve. The
10. system pressure switch will close that system’s solenoid valve when set pressure is established. The pump pressure switch will turn the pump off when set pressure is es­tablished.

11.
If another system is to be filled, turn the “Man-O-AUTO” switch to “O” and select the next system using switches A and B.
12.
Turn the “Man-O-AUTO” switch to “Man” and repeat steps 8 through 10.
13.
After filling all systems and the CS-1 tank, close the liquid supply valve. All air must be out of the system before switching the unit to maintenance mode. Follow
14. the system manufacturer’s recommendations to ensure all air is removed.
G. Operating in Maintenance Mode: Automatic
As previously stated, the CS-1 is designed to maintain the antifreeze pressure in the sprin­kler system at a supervisory pressure of 50 PSI (3.4 Bar). A pressure switch installed in the pump discharge line operates the pump between two pressures sensed in the unit’s piping. A pressure switch on each system sends a signal to the CS-1 to open and close that system’s solenoid valve.
Ensure all air is removed from system piping before placing the unit in automatic operation. Liquid level in the storage tank must be above the level switch height or pump operation is
inhibited. Close the liquid supply and tank fill isolation valves. Open the tank discharge isolation valve
and system liquid supply isolation valve. With the “ON-OFF” switch “ON”, switch the “Man-O-AUTO” switch to the “AUTO” position. The
CS-1 is now operating in Maintenance mode. NOTE: The CS-1 control system uses a time delay relay, set at 10 minutes, to limit pump
operation to six times per hour maximum. When the unit is first energized in “AUTO”, pump operation is delayed for 10 minutes.
After 10 minutes, if the CS-1 piping is below the unit’s pressure switch setting, the pump motor will operate, raising CS-1 manifold pressure.
The pump will turn off at the pressure switch cutout pressure. Each system’s solenoid valve will open in response to system pressure switch.

11. Air / Vacuum Vent
The Viking AV-1 device is a float operated automatic air vent that is installed at high points of the sprinkler system where air pockets can accumulate. As the sys­tem fills, air is automatically vented through the orifice of the vent valve. When the system is full, the water or antifreeze solution raises the float due to buoyancy and shuts off the outlet orifice. As air throughout the system accumulates at the high points of system piping, it will be automatically expelled to provide air-free system piping.
Airflow during venting is restricted due to differential pressure across vent orifice. It is recom­mended to slow fill the system initially to minimize the buildup of air in the system. See Table 16 for air flow capacity at various differential pressures.
Having the AV-1 installed on the end of each high-point branch line and/or main provides quick­er and more complete drainage of system piping. This is because during drainage of system piping, the AV-1 will open and allow air to enter and break the vacuum inside the piping.

A. Installation
The AV-1 shall be installed at all high points of the ESFR Cold Storage piping, including branch lines and main feed lines.
In order to install the AV-1 assembly in the space from the ceiling to the sprinkler, the isolation ball valve and strainer must be installed in the horizontal position as illustrated in Figure 2 and the AV-1 must be installed with the (2) outlet connections at the top location. This position is critical in order to allow the float within the device to operate properly.
The outlet connection needs to be piped using 3/8” (9.5 mm) outside diameter plastic or copper tubing unrestricted downward and away from protected product below. This is due to possible small amounts of moisture that could spurt out during venting of the system. Copper is recom­mended in order to function during and after fire situations and long-lasting durability. Attach to the ½” NPT vent connection as shown in Figure 32.
B. Ordering Information
Model AV-1 Valve and Trim Kit: Part Number 13495 Model AV-1 Vent Valve Only: Part Number 13494
C. Inspections, Tests and Maintenance
The top inlet connection can be used as a sampling discharge connection that can be
1. piped to a floor level location, or attach a manual bleed valve to take sample antifreeze from desired locations. If this connection is not being used, then it must be plugged with the pipe plug furnished with product. Regular inspection for leakage from the discharge outlet and plugging of the strainer is
2. recomended. By shutting off the isolation valve, open strainer screen plug, drain liquid from the assembly, the float should open. Check the strainer for debris, clean. and re­assemble. Open the isolation valve slowly and make sure the AV-1 vents and shuts off when filling with liquid. Opening the isolation valve slowly will prevent the alarm system from operating due to fast liquid flow past the sprinkler system alarm valve. When using the outlet connection as a sample point for the antifreeze system, allow to
3. flow long enough to obtain solution sample from the branch pipe area and not from the drop leg of the sample tube. It is normal on hydronic systems to have no discharge from the auto vent valves.
4. During routine maintenance of the unit, observe air flow from the vent during recharge
5. of the AV-1. During proper operation, air will flow from outlet followed by a small amount of liquid, then shut off. If debris is collected on the seat, liquid leakage will occur. Isolate with the ball valve.
6. Remove the AV-1 and back flush using clean water through the outlet vent connection to flush out scale and debris. Re-check operation before reinstallation. If there is still improper function, replacement of the AV-1 valve is required.
