SECTION: B GENERAL INFORMATION
B-1) To the Purchaser:
Congratulations! You are the owner of one of the finest pumps
on the market today. Weinman® Pumps are products
engineered and manufactured of high quality components.
With years of pump building experience along with a
continuing quality assurance program combine to produce a
pump which will stand up to the toughest applications.
This Weinman Pump manual will provide helpful information
concerning installation, maintenance, and proper service
guidelines.
B-2) Receiving:
Upon receiving the pump, it should be inspected for damage
or shortages. If damage has occurred, file a claim immediately
with the company that delivered the pump. If the manual is
removed from the crating, do not lose or misplace.
B-3) Storage:
Short Term-
Weinman Pumps are manufactured for efficient
performance following long inoperative periods in storage. For
best results, pumps can be retained in storage, as factory
assembled, in a dry atmosphere with constant temperatures
for up to six (6) months.
Long Term-
Any length of time exceeding six (6) months, but
not more than twenty four (24) months. The units should be
stored in a temperature controlled area, a roofed over walled
enclosure that provides protection from the elements (rain,
snow, wind blown dust, etc..), and whose temperature can be
maintained b40 deg. F and +120 deg. F.
If extended high humidity is expected to be a problem, all
exposed parts should be inspected before storage and all
surfaces that have the paint scratched, damaged, or worn
should be recoated with a water base, air dry enamel paint. All
surfaces should then be sprayed with a rust-inhibiting oil.
Pump should be stored in its original shipping container and
on initial start up, rotate impeller by hand to assure seal and
impeller rotate freely.

SECTION C: INSTALLATION
C-1) Location:
These pumping units are self-contained and are recommended
for use in a sump or basin. The sump or basin shall be vented in
accordance with local plumbing codes. This pump is designed
to pump effluent or wastewater, nonexplosive and noncorrosive
liquids and shall
NOT
be installed in locations classified as
hazardous in accordance with the National Electrical Code
(NEC), ANSI/NFPA 70. Never install the pump in a trench, ditch,
or hole with a dirt bottom; the legs will sink into the dirt and the
suction will become plugged.
C-1.1) Submergence:
The pump should always be operated in the submerged
condition. The minimum sump liquid level should never be less
than 6 inches above the pump bottom. The recommended level
should not drop below the top of the motor housing (see Fig. 1).
C-2) Discharge:
Discharge piping should be as short as possible. Both a check
valve and a shut-off valve are recommended for each pump
being used. The check valve is used to prevent backflow into the
sump. Excessive backflow can cause flooding and/or damage to
the pump. The shut-off valve is used to stop system flow during
pump or check valve servicing.
Weinman Pumps supplies a Stainless Rail Package and also a
variety of slide-away fitting discharge systems designed to allow
the submersible wastewater pump to be installed or removed
without requiring personnel to enter the wet well. Contact your
local Weinman Pump distributor for complete details.
