A - GENERAL INFORMATION

TO THE PURCHASER:

Congratulations! You are the owner of one of the fi nest 
pumps on the market today. These 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.

Check local codes and requirements before installation. 
Servicing should be performed by knowledgeable pump 
service contractors or authorized service stations.

RECEIVING:

Upon receiving the pump, it should be inspected for 
damage or shortages. If damage has occurred, fi le a claim 
immediately with the company that delivered the pump. 
If the manual is removed from the crating, do not lose or 
misplace.

STORAGE:

Short Term - 

Pumps are manufactured for effi cient 

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.

B - INSTALLATION

1. FOUNDATION

The Motor-Mount pumps can be installed on any 
suffi ciently soild foundation since pump and motor are 
rigidly aligned. The unit may be installed on a concrete 
foundation with anchor bolts set in place or securely 
mounted on a wall in either a horizontal or vertical position 
with motor above pump. The pump should be located as 
near the source of supply as possible with a minimum of 
suction pipe and elbows. Maximum suction lift, (lift plus 
pipe friction is 15 feet based on 65°F water at sea level.

Foundation bolts, of the proper size, should be imbedded 
in the concrete. A pipe sleeve, about 2½” diameters larger 
than the bolt, should be used to allow for fi nal positioning 
of the bolts. See Figure 1.

Position unit on foundation and level using rectangular 
metal blocks and shims, or wedges having a small taper as 
shown in Figure 2.
 

2. PIPING

A foot valve and strainer must be installed on the lower 
end of the suction pipe to keep pump completely fi lled with 
liquid when the pump is used under suction lift conditions. 
Connect suction pipe to pump, making certain that all 
connections are airtight. When a foot valve and strainer 
are used, it is necessary to install a check valve in the 
discharge line near the pump to prevent possible casing 
damage due to line shock or surge when the pump stops. 
A gate valve should also be installed in the discharge line. 
Connect discharge pipe to pump casing.
