SECTION B: GENERAL INFORMATION

 

B-1) To The Purchaser:

Congratulations! You are the owner of one of the finest 

pumps on the market today. Barnes® Pumps are products 

engineered and manufactured of high quality components. 

Over one hundred years of pump building experience 

along with a continuing quality assurance program com-

bine to produce a pump which will stand up to the toughest 

applications.

Check local codes and requirements before installation. 

Servicing should be performed by knowledgeable pump 

service contractors or authorized service stations.

The pump is packaged ready for installation and no con-

nections or adjustments are necessary except for attaching 

discharge piping and plugging in service cord.

B-2) Receiving:

Upon receiving the pump, it should be inspected for dam-

age 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- 

Barnes 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. Pump should be stored in its original shipping 

container and before 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 recom-

mended for use in a sump or basin. This pump is designed to 

pump rain water or light effluent, nonexplosive and noncor

-

rosive liquids and shall 

NOT

 be installed in locations classi-

fied as hazardous in accordance with the National Electrical 

Code (NEC), ANSI/NFPA 70 or the Canadian Electrical Code 

(CEC).

The sump or basin shall be vented in accordance with 

local plumbing codes. Provide proper sump diameter of 

approx. 18” (457mm) minimum and depth of approx. 20” 

(508mm)minimum to allow the pump and switch to operate 

without restriction. The float switch should not come in con

-

tact with side or bottom of sump. Make sure sump is free 

of string, cloth, nails, gravel, etc. before installing pump. 

Never install the pump in a trench, ditch, or hole with a dirt 

bottom where the suction will become plugged. 

C-1.1) Submergence:

The minimum sump liquid level should never be less than 

4 inches (102mm) above the pump bottom.  

C-2) Discharge:

Discharge piping should be as short as possible. The 

installation of a check valve in the discharge piping is 

recommended for each pump being used. The check valve 

is used to prevent backflow into the sump. Excessive back

-

flow can cause flooding and/or damage to the pump. 

 

C-3) Liquid Level Controls:

Figure 2 shows a typical installation for a submersible 

pump using a piggy-back wide angle level control mounted 

to the pump.

General Comments:

1) Never work in the sump with the power on.

2) Level controls are factory set. Be certain that the level 

control cannot hang up or foul in it’s swing. Also, make 

certain the pump impeller is still submerged when the level 

control is in the ‘off’ mode.

 

3) Plug the pump plug into a receptacle. One cycle of op-

eration should be observed, so that any potential problems 

can be corrected.
