In the case of horizontal pipes mount the unit from the side if possible.
. Disconnect the power supply before making any electrical connections. There are some basic rules of thumb that apply to most flow switch installation methods however. Some installations may require an adjustment to the water pressure switch for proper low-flow protection.
No Job is Too Big or Too Small. No Job is Too Big or Too Small. Turn off the water.
Broadly speaking these include. On horizontal pipe it should be mounted on the top to avoid rust or particle accumulation from interfering with its. The device shall be listed for pressures up to 450 psi maximum water surges of 18 fps and alarm activation by a continuous flow of 10gpm.
They are used in sprinkler system to transmit electrical information due to the flow when a sprinkler head gets activated. Be sure the direction-of-flow arrow points in the right direction otherwise a Mount detector at least 6 inches from a fitting which changes the direc-tion of the water flow or no closer than 24 inches from a valve or drain. The switch must be located downstream of any shutoff valve.
Test your system and ifanecessary adjusttthecwater pressureiswitch as describeduin the installation manual onmpager32. We provide an array of accurate flow switches that can act as an automatic control or safety device by stopping motors or activating an alarm when liquid flow is low or interrupted. The Potter VSR series is the industry standard for flow switches for fire sprinkler systems and is compatible with the widest range of pipe schedules 5 through 40 in the industry as well as all necessary listings and approvals for installation worldwide.
BE SURE DIRECTION-OF-FLOW ARROW MATCHES ACTUAL DIREC-TION OF FLOW IN THE PIPE. On vertical pipe it should be mounted where there is an upward flow. The device shall be Listed for installation on pipe schedules from 5-40 for 2 6 and schedule 10-40 for 2 through 8 size.
In underground installations sensor tees are usually installed with the insert located in the 1200 oclock or straight up position to make removal easier. Set if the flow of water stops before the entire delay has elapsed. Remove the enclosure cover.
The sensor tip must be completely immersed in the medium. Broadly speaking these include. Step 1 Turn off the fuse to cut the electricity going to the device to which you want to wire the water flow switch.
Installing flow switches on a straight section of pipe or duct Ensuring theres a good length of straight pipe both in front of and behind the switch - ideally the equivalent of 10x the pipes diameter. Recommended installation is one flow switch per module. Batesville Road 0614 Greer South Carolina 29650 864 416-0190 FAX.
Refer to the instructions that come with the switch to cut out the right size section. Same Day Response Free Quotes. All switches actuate when the water flow rate is 10 gallons per minute or greater but will not actuate if the flow rate is less than 4 gallons per minute.
This System Sen-sor installation manual covers the following waterflow detectors for sprinkler fire alarm applications. 864 416-0195 The ENTRON Water Flow Switch Option WFS includes 1 Water Flow Switch Assembly 600297-004 equipped with 38 hose. Paddle flow switch tips.
When the unit is to be mounted at the bottom of the pipe it should be free from deposits. With a hacksaw cut out a section of the PVC part of the water pipe that leads to your device. F261 Series Flow Switches Installation Instructions 7 To adjust the setting of the flow switch.
Turn the adjustment screw clockwise to raise the flow rate required to activate the switch. Other general installation rules include. Adjust the controls flow rate Figure 11.
Flow switches monitor the flow of liquid in pipelines servicing heating systems air conditioning and processing installations to help ensure safety and protect equipment. The waterflow switch shall be a model VSR manufactured by Potter Electric Signal Company LLC. There are some basic rules of thumb that apply to most flow switch installation methods however.
The sensor is supplied with 48 wire leads. The flow switch should be mounted six to seven feet above the ground. If the flow sensor is installed below grade provide access to the sensor by installing a valve box or meter pit over it.
Delay units are available to prev. The minimum rated flow rates are listed in the installation manual on page 13.
