Deep Well Submersible Pump

Installation (Continued)

To prevent sand- locking pump,

follow this procedure when starting pump for the first time. Do not start pump with discharge valve completely open unless you have followed this procedure first.

1.Connect a pipe elbow, a short length of pipe, and a gate valve to pump discharge (at well head).

2.Mount motor control box (for a

3-wire pump) or fused disconnect switch (for a 2-wire pump) in a permanently weatherproof place. Make sure that controls will not be subjected to extreme heat or excess moisture.

3.Make sure controls are in OFF position.

4.Connect motor leads and power supply to motor control box or magnetic starter (see Installation Wiring Diagrams). Do not start pump yet.

5.Open gate valve on discharge one- third of the way. Start pump (see Figure 8).

10.Install sanitary well seal or pitless adapter unit, well unit, electrical conduit and surface piping.

Installation must meet all applicable national and local codes.

High pressure and tank explosion hazard! To prevent overpressurization, install a pressure relief valve capable of releasing pump air flow at 75 psi (517.1 kPa) when using air-over-water pressure tank. When using a pre-charged pressure tank, install a pressure relief valve that will release entire air flow at 100 psi (690 kPa). Install this valve between pump and tank.

use only plumber's seal tape on

threaded joints in plastic pipe. Pipe joint compound can cause cracking in plastics.

do not allow pump or piping system to freeze. Failure to do so could result in

serious damage to equipment and will void warranty.

CONNECTING TO TANK/WATER SYSTEM

See Figure 9 for illustration of piping connections to pre-charged pressure tanks.

Before starting pump, check to make sure that pre-charged air pressure is 2 psi (13.8 kPa) below pump cut-in setting. (For example, in a tank used with a 30-50 psi pressure switch, the pre-charged pressure should be 28 psi [193.1 kPa].) Adjust pressure by adding or releasing air from the tire valve located on top of tank. Check pre- charged pressure annually and adjust as needed.

STANDARD TANK HOOKUP

See Figure 10, on page 6, for illustration of piping connections to standard pressure tank as well as distance between air release ports and tank.

6.Let water run until it is clear. (To check solids in water, fill a container with water from pump. If any solids settle after a minute, continue running pump.)

7.Once water runs clear, open gate valve two-thirds of the way and repeat step 6.

8.Once water runs clear at this setting, open gate valve completely and run pump until water is completely clear.

9.Remove gate valve (see Figures 9 and 10).
