1. The silver adjusting screw on the left front is for cut-in adjustment.
2. The yellow adjusting screw on the right is for cutout adjustment.
Although the scales are calibrated in psi, they may not correspond exactly to the actual
discharge gauge indication. Therefore, for critical installations, adjust the settings
according to the gauge reading.
Aquastat
The aquastat for high temperature cutout is set at the factory for 100°F (38°C). Adjust the
setting if a different cutout temperature is desired. Do not set the switch above 225°F
(107°C).
Optional tank
A variety of different tanks can be used with either the simplex or duplex units. Refer to
the specific IOM that was shipped with the tank for installation and operating instructions.
5.2 Pump package operation description
CAUTION:
A unit that shows symptoms of possible problems, such as overflow, noise, leaks,
vibrations, or continual operation, must be corrected immediately.
5.2.1 Variable speed operation
Variable speed simplex – for capacities up to 110 gpm
The pressure transducer monitors the system pressure and sends a feedback signal to the
controller. Depending upon the feedback, the controller then changes the speed of the
pump.
Condition Description
The system pressure falls below the set point. The pump starts automatically and pump speed
continues to ramp up until the system pressure satisfies
the set point.
The system pressure rises above the set point. The pump automatically reduces speed until the system
pressure reaches the set point, provided the minimum
run timer has expired.
Variable speed duplex – for capacities up to 220 gpm
The pressure transducer monitors the system pressure and sends feedback signal to the
controller. Depending upon the feedback, the controller changes the speed of the pump
or stages/de-stages the other pump.
