LOCATION OF DRIVE
The SubDrive Utility controller is intended for operation in ambient temperatures from -13 °F to 122 °F (-25 °C to 50 °C) at 208/230 VAC input.
The following recommendations will help in selection of the proper location of the controller:
• A tank tee is recommended for mounting the tank, pressure sensor or transducer, pressure gauge, and pressure relief valve.
If a tank tee is not used, the pressure sensor or transducer should be located within 6 ft (1.8 m) of the pressure tank to minimize
pressure fluctuations. There should be no elbows between the tank and pressure sensor or transducer.
• The unit should be mounted on a sturdy supporting structure, such as a wall or backplate secured to a supporting post.
Please take into account the weight of the unit.
• The electronics inside the SubDrive Utility are air-cooled. As a result, there should be at least 6 in (15.2 cm) of clearance on
each side and 18 in (45.7 cm) below the unit to allow room for air flow.
• The mounting location should have access to 115 or 208/230 VAC electrical supply and to the submersible motor wiring.
To avoid possible interference with other appliances, please refer to the "Wire Routing" section of this manual
and observe all precautions regarding power cable routing.
• The unit should not be installed in corrosive environments.
Special Considerations for Outdoor Use
The controller is suitable for outdoor use with a NEMA 3R rating; however, the following considerations should be made
when installing the controller outdoors:
• The unit MUST be mounted vertically with the wiring end oriented downward, and the cover must be properly secured
(also applies to indoor installations).
• NEMA 3R enclosures are capable of withstanding downward-directed rain only. The controller should be protected from
hose-directed or sprayed water, as well as blowing rain. Failure to do so may result in controller failure.
• The controller should NOT be placed in direct sunlight or other locations subject to extreme temperatures or humidity.
• Appropriate screening should be used for the air inlet and outlet when installed in areas where insect or small animal
intrusion is an issue. See "Accessories" on page 26 for ordering information.
CAUTION: Installation of non-approved screening may damage the drive and/or reduce drive output.
Screens should be cleaned on a regular basis to ensure the proper airflow needed to cool the controller.
