Section 2: Installation

General

The Dripmaster installation procedure is simple and does not require any special tools, but requires

site preparation.

Well Site Requirements

• Line power (115 VAC or 220 VAC), or 24 V AC/DC must be available at the well pump.

• An eight-wire control cable (containing wires not smaller than 22 AWG) needs to be laid

between the well pump and the local PLC enclosure.

• A sturdy, vertical pole with a welded metal plate should be in close proximity to the well pump.

Note: For large oil tanks (35 to 50 gallons), mount the Dripmaster to the oil tank stand.
