Before You Install Your Pump
NOTICE
1. The pump’s water suction inlet must not be more
than 20’ above the water level.
2. Long runs and many fittings increase friction
and reduce water flow to the pump. Locate pump
as close to water source as possible; use as few
elbows and fittings as possible. Be sure suction
line is straight and angles up toward pump to
avoid air lock.
3. Be sure well and pipe are clear of sand, dirt and
scale. Foreign matter will plug pump and void
warranty. Use new pipe for best results.
4. Protect pump and all piping from freezing.
Freezing will split pipe, damage pump and void
warranty. Check locally for frost protection
requirements. Pipe cannot be installed above
frost line and pump must be insulated.
5. Foot or check valves must be installed in suction
pipe to maintain prime and filter debris.
6. Be sure all pipes and valves are clean and in
good shape.
7. No air pockets in suction pipe.
8. No leaks in suction pipe. Even the smallest leak
in the suction piping will prevent priming. Use
Teflon tape or other approved sealants to seal
pipe joints.
9. Unions installed near pump and well will aid in
servicing. Leave room to use wrenches.
Risk of explosion.
Do not ground to a gas supply line.
Pump body may explode if used as a booster pump
or other than a lawn sprinkling application.
Risk of burns.
Motor normally operates at high temperature and will
be too hot to touch. It is protected from heat dam-
age during operation by an automatic internal cutoff
switch.
Before handling pump or motor, stop motor and allow
it to cool for 20 minutes.

Cased Well/Dug Well Installation
1. Inspect foot at in-line check valve to be sure it
works freely. Inspect strainer to be sure it is clean
and secure.
2. If using foot valve, connect foot valve and strainer
to first length of suction pipe and lower pipe into
well. Add sections of pipe as needed, using Teflon
tape on male threads.
Be sure all suction pipe is leak proof or pump will
lose prime and fail to pump. Install foot valve 10 to
20 ft. (3 to 6 m) below lowest level to which water
will drop while pump is operating (pumping water
level). Your well driller can furnish this information.
3. To prevent sand and sediment from entering
pumping system, foot valve/strainer should be at
least 5 ft. (1.5 m) above bottom of well.
4. When proper depth is reached, install sanitary well
seal over pipe and in well casing. Tighten bolts to
seal casing.
5. When using foot valve, a priming tee and plug are
recommended. (Fig. 1).
