SAFETY FIRST!

Please Read This Before Installing Or Operating Pump.
This information is provided for SAFETY and to PREVENT
EQUIPMENT PROBLEMS. To help recognize this information,
observe the following symbols:

IMPORTANT! Warns about hazards that can result
in personal injury orIndicates factors concerned with
assembly, installation, operation, or maintenance which
could result in damage to the machine or equipment if
ignored.

CAUTION! Warns about hazards that can or will cause minor
personal injury or property damage if ignored. Used with symbols
below.

WARNING! Warns about hazards that can or will cause serious
personal injury, death, or major property damage if ignored. Used
with symbols below.

Hazardous fl uids can
cause fi re or explo-
sions, burnes or death
could result.

Biohazard can cause
serious personal injury.

Rotating machinery
Amputation or severe
laceration can result.

Only qualifi ed personnel should install, operate and repair
pump. Any wiring of pumps should be performed by a qualifi ed
electrician.

WARNING ! To reduce risk of electrical shock, pumps and
control panels must be properly grounded in accordance
with the National Electric Code (NEC) or the Canadian
Electrical Code (CEC) and all applicable state, province,
local codes and ordinances. Improper grounding voids
warranty.

WARNING! To reduce risk of electrical shock, always
disconnect the pump from the power source before
handling or servicing. Lock out power and tag.

WARNING! Operation against a closed
discharge valve will cause premature bearing
and seal failure on any pump, and on end

suction and self priming pump the heat build
may cause the generation of steam with resulting dangerous
pressures. It is recommended that a high case temperature
switch or pressure relief valve be installed on the pump body.

CAUTION ! Pumps build up heat and pressure

during operation-allow time for pumps to cool

before handling or servicing.

Extremely hot - Severe
burnes can occur on contact.

Hazardous fl uids can Hazard-
ous pressure, eruptions or ex­plosions could cause personal
injury or property damage.

Hazardous voltage can
shock, burn or cause death.

WARNING ! Do not wear loose clothing that may

become entangled in moving parts.

WARNING ! Keep clear of suction and discharge

openings. DO NOT insert fi ngers in pump with power
connected.

Always wear eye protection when working on pumps.

Make sure lifting handles are securely fastened each
time before lifting. DO NOT operate pump without safety
devices in place. Always replace safety devices that
have been removed during service or repair. Secure the
pump in its operating position so it can not tip over, fall
or slide.

DO NOT exceed manufacturers recommendation for

maximum performance, as this could cause the motor
to overheat.

WARNING ! To reduce risk of electrical shock, all wiring

and junction connections should be made per the NEC
or CEC and applicable state or province and local
codes. Requirements may vary depending on usage
and location.

WARNING! Products returned must be cleaned,

sanitized, or decontaminated as necessary prior to
shipment, to insure that employees will not be exposed
to health hazards in handling said material. All Applicable
Laws And Regulations Shall Apply.

Bronze/brass and bronze/brass fi tted pumps may

contain lead levels higher than considered safe for
potable water systems. Lead is known to cause cancer
and birth defects or other reproductive harm. Various
government agencies have determined that leaded
copper alloys should not be used in potable water
applications. For non-leaded copper alloy materials of
construction, please contact factory.

Crane Pumps & Systems, Inc. is not responsible for

losses, injury, or death resulting from a failure to observe
these safety precautions, misuse or abuse of pumps or
equipment.

WARNING ! Do not pump hazardous materials
(fl ammable, caustic, etc.) unless the pump is specifi cally
designed and designated to handle them.

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.

B - BEFORE YOU BEGIN

Motor driven pumps are carefully aligned on sub-base
before shipment. However, after they are placed upon the
foundation and sub-base is bolted down, the alignment
must be rechecked and in MOST CASES it will be found
necessary to carefully realign the unit. Quite often a noisy
pump is due to pump and motor not being properly aligned.
IN SUCH CASES WE DISCLAIM ALL RESPONSIBILITY
FOR PROPER WORKING OF PUMP.

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 between +40 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.

SERVICE CENTERS:

For the location of the nearest Deming Service Center,
check your Deming representative or Crane Pumps &
Systems Service Department in Piqua, Ohio, telephone
[phone] or Crane Pumps & Systems Canada, Inc.,
Bramton, Ontario, [phone].

C - INSTALLATION

1. A good rigid foundation must be provided for pump
base.

2. Place pumping unit on foundation with bolts, of the
proper size, 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. Level sub-base, to give a space of about 3/4”
for grouting, using rectangular metal blocks and shims,
or wedges having a small taper as shown in Figure 2.

Figure 2. Adjusting Wedges for Mounting

3. Align the pump and motor shafts at the fl exible coupling.
Hold a straight edge on the top of the coupling so that it
extends over both halves. Straight edge should rest
evenly across both rims of the coupling halves when the
straight edge is placed on the top, sides and bottom with
no light showing between the straight edge and rim of
the coupling. Also check vertical alignment of the
coupling faces with a thickness gauge. Faces must be
parallel and spaced about 1/8” apart when the motor
rotor is at its extreme position towards the pump. This
safe guards the pump shaft being crowded endwise by
the motor shaft end play. By proper adjustment of metal
shims under pump or motor, both halves of the fl exible
coupling can be brought into alignment See Figure 3.
