SH1434QV Continued
1. Close the ball valve at the outlet of the SH1434 or LFSH1434
and MM434 or LFMM434 valve #2, #3, #4 and #5.
2. Open the ball valve at the outlet of the MM434 or LFMM434
valve #1.
3. Open enough fixtures to meet the minimum flow requirement
of the MM434 or LFMM434 valve #1 as per table 2.
4. Set MM434 or LFMM434 valve #1 temperature (refer to IS-P-
MM430 if required).
5. Close ball valve at the outlet of the MM434 or LFMM434 valve
#1 and open the ball valve at the outlet of the MM434 or
LFMM434 valve #2. Repeat steps 3 and 4.
6. Close ball valve at the outlet of the MM434 or LFMM434 valve
#2 and open the ball valve at the outlet of the MM434 or
LFMM434 valve #3. Repeat steps 3 and 4.
7. Close ball valve at the outlet of the MM434 or LFMM434 valve
#3 and open the ball valve at the outlet of the MM434 or
LFMM434 valve #4. Repeat steps 3 and 4.
8. Close ball valve at the outlet of the MM434 or LFMM434 valve
#4 and open the ball valve at the outlet of the MM434 or
LFMM434 valve #5. Repeat steps 3 and 4.
9. Loosen the locknut at the top of the PRV #2. This must be all
the way out or you will be limiting range of the adjustment.
10. Adjust the PRV #2 so the outlet pressure gauge (top) reads
20psi less than the supply pressure gauge (bottom). Turning
the adjustment screw counterclockwise will increase the dif-
ferential across the PRV (allowing the PRV to open later).
11. Open the ball valve on the outlet of the MM434 or LFMM434
valve #1.
12. Close the ball valve at the discharge of the MM434 or
LFMM434 valve #5.
13. Loosen the locknut at the top of the PRV #1. This must be all
the way out or you will be limiting range of the adjustment.
14. Adjust the PRV #1 so the outlet pressure gauge (top) reads
15psi less than the supply pressure gauge (bottom). Turning
the adjustment screw counterclockwise will increase the dif-
ferential across the PRV (allowing the PRV to open later).
15. Open the ball valve on the outlet of the SH1434 or LFSH1434
valve.
16. Close the ball valve of MM434 or LFMM434 valve #1.
17. Open enough fixtures to meet the minimum flow requirement
of SH1434 or LFSH1434 as per table 2.
18. Set SH1434 temperature (refer to IS-P-SH1430 if required).
19. Open ball valves at the outlets of SH1434 or LFSH1434 and all
5 MM434 or LFMM434 valves.
20. Verify outlet temperature remains at the set point with all
valves open at a 15psi and 20psi differential.
21. For any problem, refer to Troubleshooting section of the
document or contact Powers' Technical Support Department
at 1.800.669.5430 or [email protected].
SH1434-6V
8. Adjust the PRV so the outlet pressure gauge (top) reads 15psi
less than the supply pressure gauge (bottom). Turning the
adjustment screw counterclockwise will increase the differen-
tial across the PRV (allowing the PRV to open later).
9. Close the ball valve at the discharge of the MM434 or
LFMM434 valve #3.
10. Open the ball valve on the outlet of the SH1434 or LFSH1434
valve.
11. Open enough fixtures to meet the minimum flow requirement
of SH1434 or LFSH1434 as per table.
12. Set SH1434 or LFSH1434 temperature (refer to IS-P- SH1430 if
required).
13. Open all the ball valves at the outlets.
14. Verify outlet temperature remains at the set point.
15. For any problem, refer to Troubleshooting section of the
document or contact Powers' Technical Support Department
at 1.800.669.5430 or [email protected].
