TECHNICAL INFORMATION SPPPRODUCTS.COM 115 4. Adjustment 6. Removal Maintenance & Service Transportation and Storage 5. Operation Test ............ ............. Delay Function Adjustment 4.1 The original set time is 30 seconds, if need to adjust the time, rotate the rotary knob to make sure the arrow direct to the scale, increase time with clockwise rotating, and reduce the time by anticlockwise rotating. 5.1 System full of water, check if there's leakage around the water flow indicator, verify the leakage position. a. leakage between the connecting plate and the saddle Open the cover, fasten the hexagon nuts. b. leakage between the saddle and pipe Fasten the U-bolts alternately, make sure the sealing surface is even & uniform. c. leakage from the rod sealing gasket Contact the customer service agent to replace the rod sealing gasket If leakage found except for a, b, and c, drain the water in the system, remove the saddle, check if there's other material or inclusion under the sealing gasket, make sure the pipe should be no defects of bulge or sunken, then install again. 4.2 The unit of the scale is second, the accuracy is 50%. 5.2 Adjustment of Delay Time ............. Caution: The delay time must not exceed 90 seconds when adjusting the rotary knob. Ajust the rotary knob, if delay time is not as desired, to increase time with clockwise rotating, and reduce the time by anticlockwise rotating. ..................... ............. ............ When need to remove the water flow indicator due to improper operation or other reasons. a. Turn off electrical power, drain the water of the pipe. b. Loosen the two nuts to remove the U-bolts. c. Lift the saddle far enough to get your fingers under it. With your fingers, roll the vane so it will fit through the hole while continuing to lift the water flow indicator. Caution: inspect and make sure the vane lifts from the pipe, otherwise will block the pipe. 1. During transportation, take care to prevent violent vibration, throwing, collision, etc., and with proper protection from rain or chemical erosion. 2. When receiving the water flow indicators, check and confirm if there's damage during transportation, and put them on the ground carefully. 3. The water flow indicator should be stored in a clean, dry, well-ventilated place with non-corrosive environment. 1. Quarterly Inspection a. Inspection requirement: appearance and marking inspection, function of the start and reset of the water flow indicator; accuracy of signal delivery. b. Inspection operation: check the appearance of the water flow indicator; open the test & drain assembly and test valve of the floor, and verify the signal action of the water flow indicator from the fire control equipment; close the test & drain assembly and test valve, and verify the signal reset of the water flow indicator from the fire control equipment. 2. When the water flow indicator is damaged from fire or other causes, replace for a new one immediately. 3. The retard and switch assembly are easily replaceable at field. Contact the sales agent if there is problem with any parts.
