personnel/operators prior to installation and operation,
and it must always be kept close to the location of the
pumping unit for easy access.
G.1 Summary of Safety Marking.
The safety instructions contained in this manual whose
non-observance might cause hazards to persons are
specially marked with the symbol:
General hazard sign to ISO 7000 - 0434.
The word "Caution" is used to introduce safety
instructions whose non-observance may lead to damage
to the machine and its functions. The word “Danger” is
used to introduce safety instructions whose non-
observance may lead to injury or loss of life to people
and damage to the machine or its functions.
Instructions attached directly to the machine, e.g.
Arrow indicating the direction of rotation
Markings for fluid connections must always be
complied with and be kept in a perfectly legible
condition at all times.
Observe all note, caution or danger tags attached to the
equipment or included in this manual.
G.2 Non-compliance with Safety Instructions.
Non-compliance with safety instructions may result in
personal injury, property damage, or unnecessary
damage to the pumping unit. Non-compliance with these
safety instructions will also lead to forfeiture of any and
all rights to claims for damages. Non-compliance, can
for example, result in:
Failure of important pumping unit functions.
Failure of prescribed maintenance and servicing
practices.
Hazard to personnel by electrical, mechanical,
and chemical effects as well as explosion.
Hazard to the environment due to leakage of
hazardous substances.
G.3 Safety Instructions for Maintenance, Inspection,
and installation Work.
The operator is responsible for ensuring that all
maintenance, inspection and installation work be
performed by authorized, qualified personnel who are
thoroughly familiar with the manual and pumping unit.
The pumping unit must have cooled down to ambient
temperature, pump pressure must have been released
and the pump must have been drained before working
on any pumping unit.
Work on the pumping unit must be carried out during
shutdown. The shutdown procedure described in the
manual for taking the unit out of service must be
adhered to.
Pumps handling fluids that are hazardous to personnel
must be decontaminated prior to being worked on.
Immediately following completion of the work, all safety
relevant and protective devices must be reinstalled
and/or reactivated.
Please observe all instructions set out in the section on
start-up before returning the pumping unit to service.
G.4 Unauthorized Modification and Manufacture of
Spare Parts.
Modifications or alterations of the pumping unit supplied
are only permitted after consultation with Carver Pump
and to the extent permitted by Carver Pump. Original
spare parts and accessories authorized by Carver Pump
ensure safety. The use of other parts can invalidate any
liability of Carver Pump for consequential damage
and/or warranty.
G.5 Unauthorized Modes of Operation.
The warranty relating to the operating reliability and
safety of the unit supplied is only valid if the pumping
unit is used in accordance with its designated use as
described in the following sections. The limits stated on

II. INSPECTION AND STORAGE.
A. INSPECTION. Upon receipt of the shipment,
unpack and inspect the pumping unit and individual
parts to insure none are missing or damaged. Carefully
inspect all boxes and packing material for loose parts
before discarding them. Immediately report any missing
parts or damage incurred during shipment to the factory
and to the Transportation Company and file your
“damage and/or lost in shipment” claim with the carrier.
B. STORAGE OF PUMP. If the equipment is not to be
immediately installed and operated, store it in a clean,
dry, well-ventilated place, free from vibrations, moisture
and rapid or wide variations in temperature.
NOTE
Storage requirements vary depending on
climatic environment, length of storage and
equipment. For storage periods of three months
or longer, contact manufacturer for specific
instructions. Improper storage could damage
equipment and would result in non-warranty
covered restoration of non-warranty covered
product failures.
When storing the pump up to three months rotate the
shaft for several revolutions at least once per month to
coat the bearings with lubricant, retard oxidation and
corrosion, and prevent possible false brinelling.
Consider a unit to be in storage when:
1. It has been delivered to the job site and is
waiting to be installed.
2. It has been installed but operation is delayed
pending completion of construction.
3. There are long (30 days or more) periods
between operating cycles.
4. The plant (or department) is shut down for
periods of longer than 30 days.
Measures to be taken for prolonged shutdown of
installed pumping unit. If the pumping unit remains
installed a periodic check of operation is in order to
make sure that the pump is always ready for instant
start-up and to prevent the formation of deposits within
the pump and the pump intake area. Start up the
pumping unit regularly once a month or once every 3
months for a short time (approximately 5 minutes)
during prolonged shutdown periods. Prior to operation
check run ensure that there is sufficient liquid available
for operating the pump.
III. INSTALLATION.
A. LOCATION. The pump assembly should be
located in an area that will permit periodic inspection
and maintenance. Head room and access should be
provided and all units should be installed in a dry
location with adequate drainage. The discharge piping
should be direct with as few elbows and fittings as
possible.
B. HANDLING.
CAUTION
Use a hoist with adequate lifting capacity.
Do not pick up the complete unit by the motor
or the pump shafts or motor lifting eyes.
If the pumping unit slips out of the sling
arrangement, it may cause injury to personnel
and/or damage to the pumping unit.
Moving the unit requires proper preparation and
handling. Always make sure that the pump cannot slip
out of the transport suspension arrangement. The RSV
pumps with motor installed tend to be top heavy; care
should be taken in handling and transporting to prevent
damage or injury caused by the pump falling over.
C. COUPLING ALIGNMENT. The pump and motor
are connected by a coupling. The base aligns the pump
and motor. No further alignment is necessary.
D. PRE-INSTALLATION PROCEDURES.
1. Always check the pump label against the
requirement to make sure you are installing the
proper pumps specified for the job.
2. Make sure that the pump suction marked by a
sticker, is connected to the liquid source and
that the discharge, similarly marked, is
connected to the discharge line.
