NOTICE:
For proper
performance,
pump
MUST be
matched
to ejector
and to well depth.
Use this pump
on wells 25' to 210' deep.
1.
Long runs and many fittings increase
friction
and re-
duce flow. Locate pump
as close to well as possible:
use as few elbows
and fittings
as possible.
2.
Be sure well is clear
of sand.
Sand will plug the
pump
and void the warranty.
3.
Protect pump
and all piping from freezing. Freezing
will split pipe, damage pump
and void the warranty.
Check
locally
for frost
protection
requirements
(usually
pipe
must
by 12" below
frost
line and
pump
must be insulated).
4.
Be sure all pipes
and foot valve are clean and in
good shape.
5.
No air pockets
in suction
pipe.
6.
No leaks in suction
pipe. Use Teflon tape or Plasto-
Joint Stik to seal pipe joints.
7.
Match pump
to well.
IMPORTANT:
Flow into well
must
at least equal
flow out through
pump!
8.
Unions installed near pump
and well will aid in ser-
vicing. Leave room to use wrenches.
[ak CAOTION ] Motor normally
operates
at high temper-
ature and will be too hot to touch.
It is protected
from
heat damage during operation
by an automatic
internal
cutoff
switch.
Before
handling
pump
or motor,
stop
motor
and allow it to cool for 20 minutes.
