Controller Location Selection
The SubDrive controller is intended for operation in ambient temperatures
up to 125°F (51°C) at 230 VAC input. The following recommendations will
help in selection of the proper location of the SubDrive unit:
1. A tank tee is recommended for mounting the tank, pressure sensor,
pressure gauge, and pressure relief valve at one junction. If a tank
tee is not used, the pressure sensor should be located within 6 feet
(1.8 meters) of the pressure tank to minimize pressure fl uctuations.
There should be no elbows between the tank and pressure sensor.
2. The unit should be mounted on a sturdy supporting structure such as a
wall or supporting post. Please take into account the weight of the unit,
which weighs approximately 34 pounds (15.5 kg).
3. The electronics inside the SubDrive are air-cooled. As a result, there
should be at least 6 inches of clearance above and below the unit to
allow room for air fl ow.
* NOTE: there should be no elbows between the tank and pressure sensor.
