Any non-conforming materials must be labeled by store keeper and returned to quarantine area in accordance with procedure.5.1.5 Ensure that all the pipe fitters and helpers are aware of the correct materials handling and installation procedure to ensure that best quality of workmanship. Training shall be provided by site engineers / Supervisor as and when required.5.1.6 Ensure space & access for installation is available and at correct location as per the approved drawing and site conditions.5.1.7 Check the tools required to install the Alarm Check valve.5.1.8 Supervisor shall ensure that correct tools and Alarm check valve with trim kit are available for installation and to achieve compliance with contract requirement.

5.2 INSTALLATION OF ALARM CHECK VALVE5.2.1 The Alarm Check Valve must be installed in an area not subject to freezing temperatures or physical damage. The Alarm Check Valve may be installed in the vertical position with direction of flow up, or in the horizontal position with the access cover up.5.2.2 Verify that the appropriate trim chart and technical data for the Alarm Check Valve and associated equipment are available.

5.2.3 Remove all plastic thread protectors from the openings of the Alarm Check Valve.

5.2.4 Apply a small amount of pipe-joint compound or tape to the external threads of all pipe connections required. Take care not to allow any compound, tape, or other foreign matter inside any nipples or openings of the valve or trim components. Trim the Alarm Check Valve in accordance trim chart provided along with the alarm check valve

5.2.5 Install the Alarm Check Valve and trim according to current Trim Charts for the valve used. Trim charts are provided with trim package and available with the project engineer or Technical Engineer. After installing the alarm check valve, please unpack the water motor gong and follow the instructions below to install as per the requirement.





5.2.6 For installation of water motor gong mark the through-wall locations for the centerlines of the Sleeve and Drain Outlet. The Drain Outlet must be located at least 10 inches (250mm)

5.2.7 Make 1-1/2 inch (38 mm) diameter holes straight through the wall at both locations.

5.2.8 Cut the non-threaded end of the Sleeve to a length equal to that of the wall thickness plus 0 to 1/8 inch (0 to 3 mm). Thread the cut end to inch NPT per ANSI B1.20.1.

5.2.9 Install the alarm line piping up to and including the union half. Use thread sealant sparingly on male threads only.

5.2.10 Prior to initiating installation of the Water Motor Alarm, mount the Drain Trim (less the Wall Plate and 45 Elbow), as well as the balance of alarm line piping (including other union half) to the Water Motor.

5.2.11 Tighten the NPT threaded end of the Sleeve into the Body hand tight plus 1/8 turn.

5.2.12 Slip the Support Washer over the Sleeve and place the assembly in position against the wall.

5.2.13 Tighten the 3/4 inch Union. Install the Wall Plate and tighten the 45 Elbow.

5.2.14 Apply pressure against the outside edge of the Water Motor Body and verify that the Body and Support

5.2.15 Washer sit square against the wall. If not, adjust the alarm line and/or drain piping to suit.

5.2.16 From the outside wall, insert the Drive Shaft through the Sleeve and fully insert it into the Impeller. (When fully inserted, the Shaft should protrude beyond the face of the wall by approximately 20" minus 2" minus wall thickness.) Mark the Drive Shaft at a point of approximately 1/8 to 1/4 inch inside the face of the wall; remove the Shaft; cut the Shaft where previously marked; file off burrs from the cut end of the Drive Shaft; and, re-insert the Drive Shaft through the Sleeve and fully insert it into the Impeller.

5.2.17 Hold the Gong Mount in position against the wall, engage the Coupling with the Drive Shaft and then carefully thread the Striker Shaft Bearing onto the Sleeve. Securely tighten the Striker Shaft Bearing using a pair of channel locks on the 1-1/2 inch (38 mm) hex end.





5.2.18 Spin the Striker by hand and verify that it spins freely (without any sign of binding). If not, make the necessary adjustments.

5.2.19 Install the gong and securely tighten the Cap Nut. The identification sign lettering must be orientated horizontally.

5.2.20 After installation, the alarm check valve must be tested in accordance with the recognized installation standards. If a thread leak occurs or the groove joints leak, normally the unit must be removed and the joints should be done again. This is due to the fact that when the joint seal leaks, the sealing compound or tape is washed out of the joint or the groove of the pipe might more or the groove fittings gasket might be damaged.

5.2.21 Ensure the alarm check valve is installed as per the procedure and the trim connections are installed as per the trim chart.

5.2.22 Verify that all system components are rated for the water working pressure of the system.
