Powers PowerStation XP Single and Multi-Valve Series - Single Valve 1 - 208 gpm - Manual (Page 2)

NOTE: Perform all 15 steps before moving on to the next sec-
tion. Steps 1-15 are to set thermostatic valve.
1. Close B3, B4 and B6.
2. Close D1 and D2.
3. Open B1, B2 and B5.
4. Connect hose to D2 and run to a drain.
5. Open D2 with a screwdriver and verify flow to drain is greater
than the minimum flow of the valve.
6. For system with an automatic balancing valve, adjust the knob
to full hot position (force the water through the hose).
7. If flow rate is less than the minimum flow, turn pump P1 on.
8. Let valve run until readings on inlet gauges T/P2 & T/P3 are
steady.
9. Adjust temperature of mixing valve to desired set point (read
temperature on T/P1). Refer to IS-P-MM430 and IS-P-SH1430
10. Lock temperature screw/locknut in place.
11. Turn off pump.
12. Close B5 and open B4.
13. Open D1 to purge air out of recirculation line.
14. Close D1 when you begin to get water.
15. Open B6 and wait until T/P4 reaches the maximum recir-
culation temperature (must be less than the mixing valve
setpoint).
16. Skip to the type of recirculation below.
1. Flush all piping thoroughly before installing.
2. Check for leaks.

Set Up Procedure
n
2
1. Close D2
2. Open B3 fully and open C1 approximately 10%.
3. Allow time for recirculated water to travel around the loop.
4. If the temperature at the T/P4 begins falling, you will need to
open C1 another 10%.
5. If the temperature at T/P4 begins to rise, you will need to
close C1 by 5%.
6. Repeat steps 4 and 5 until the temperature at T/P4 is stable
(less than the set point of the mixing valve).
7. The system is now set.
Continuous Recirculation
n
1. For systems with an automatic balancing valve, adjust the
knob to the full cold position (restricts the flow of water in the
hose to a trickle).
2. Slowly turn the automatic balancing valve's knob toward the
hot position until you just start to get water through the hose.
At this point, it is set to the temperature shown on T/P4.
3. Close D2.
4. Open B3.
5. The system is now set.
NOTE: For any problem, refer to Troubleshooting section of the
document or contact Powers’ Technical Support Department at
1.800.669.5430 or [email protected].
Continuous Recirculation with Automatic
Balancing Valve
n
1. Close D2 and open B3.
2. Apply power to pump P1.
3. Set the pump on and off temperatures.
4. With the recirculation temperature set to its maximum, the
pump/Aquastat will remain off until the temperature cools to
the low point.
5. Wait until the recirculation line cools to the low point.
6. Verify the pump turns on at this point.
7. Verify recirculation line heats back up and turns pump off at
the maximum setting from step 3.
8. The system is now set.
