other end of safety rope securely to
well seal, well cap or pitless adapter.
NOTE: Discharge outlet is 1-1/2" NPT
threaded.
3. Install piping based on these guide-
lines:
For installations up to 100' (30.5 m)
in depth, use 100 psi (689.5 kPa)
rated polyethylene plastic pipe.
For installations up to 220' (67.1 m)
in depth, use 160 psi (1103.2 kPa)
rated polyethylene plastic.
For depths beyond 220' (67.1 m),
use galvanized steel pipe for the
entire drop pipe.
INITIAL STARTUP/NEW WELLS

pump with dis-
charge valve completely closed. This
can cause significant pump damage and
will void the warranty.
To prevent sand-

locking pump, fol-
low this procedure when starting pump
for the first time. Do not start pump
with discharge valve completely open
unless you have followed this proce-
dure 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 posi-
tion.
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).
6. Let water run until it is clear. (To
check solids in water, fill a contain-
er with water from pump. If any
solids settle after a minute, contin-
ue 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 set-
ting, open gate valve completely
and run pump until water is com-
pletely clear.
9. Remove gate valve (see Figures 9
and 10).
10. Install sanitary well seal or pitless
adapter unit, well unit, electrical
conduit and surface piping.
Installation must meet all applica-
ble national and local codes.

install a pressure relief valve capable

See Figure 9 for illustration of piping con-
nections 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 set-
ting. (For example, in a tank used with
a 30-50 psi pressure switch, the pre-
