MAGNA3 INSULATED PUMPS INSTALLATION MANUAL
Start-Up Cont.
Option 2: Constant Pressure Mode
Follow Steps below to set up the pump in Constant Pressure mode.
1. Open all of the water valves at the heat pumps for full flow.
2. Select Settings.
3. Scroll down to Control mode and press OK.
4. Scroll down to Const. press. and press OK.
5. Press to go back to the Settings menu.
6. Scroll down to Setpoint and press OK.
7. Press OK to select the psi.
8. Before changing the setting, review Steps 9 through 11 below.
9. Balance the flow if necessary. Larger applications may utilize flow control valves; smaller applications may simply have
balancing or ball valves at each heat pump.
10. Once the system is balanced, the psi setting may be adjusted. If the flow rate at the heat pumps is higher than design flow
rate, start to lower the psi setting, and recheck the flow rate at several heat pumps. Continue to adjust psi until the flow rate is
within design specifications.
11. Close some of the water valves, and recheck flow. The pump should slow down. If flow is within design specifications, press
the Home key, and place the water valves in normal operating mode. If flow rates are off, return to Step 10. Depending upon
how the system is balanced (i.e. with balancing valves or with flow control valves), this could be an iterative process.
12. If the installation is a single pump system disconnect power to the pump and remove the grey start/stop jumper. Connect the
S/S and ground wires refer to wiring section after complete turn power back on to the pump. If the installation is a dual pump
system leave the jumper in place until both pumps are setup.
