Thank you for your purchase of a RainFlo Pump Control.
Your commitment to saving water through the use of harvested rainwater is
commendable, and is a very important step towards increasing your personal water
sustainability.
To match your commitment to saving water we have committed to ensuring that
the pump controllers we offer are of the highest quality available. This pump
controller has been tested and certified ROHS compliant for your safet
y
.
The RainFlo PC115A provides automatic multifunction control for your water
pump including start and stop control based on user demand (flow), demand-side
pressure display via built-in pressure
gauge, run-dry protection and a check valve
(non-return valve) function. It provides direct control of water pumps up to 1.25
horsepower at 115V. As with most pump controllers, the system high pressure is
based on the pump output. The pump start pressure (low pressure threshold and
start trigger), is adjustable through a screw on the back side of the unit.
Your PC115A pump controller features a built-in pressure gauge located on the
right side of the unit. As with many hydraulic devices, this gauge displays
pressure in units called “bar”. One bar is approximately equal to atmospheric
pressure at sea level. In terms of water pressure,
1 bar = 14.5037 PSI.
