3200 SERIES PUMPS
Operational and Installation Guidelines
Please read these Operational and Installation Guidelines before
installing the PowerRV™ Series Pumps. If additional help is needed,
please consult the Factory.
CAUTIONS
y Water pipe connections and fixtures directly connected to a potable
water supply shall be sized, installed and maintained in accordance
with Federal, State, and local codes.
y Do not operate the pump above the pressure limitations specified
on the data label.
y Never operate the pump in a harsh environment or hazardous
atmosphere, since motor brush and switch may cause electrical
arcing.
y Do not pump gasoline or other flammable liquids. Do not use
with petroleum products.
y Do not assume fluid compatibility. If the fluid is improperly
matched to the pumps’ elastomers, a leak may occur
y As long as there is inlet water pressure, the pump will not stop
forward flow of water even if the motor is turned o. Be sure the
system has positive means of shutting o water supply.
y Always consider electrical shock hazard when working with and
handling electrical equipment. If uncertain, consult an Electrician.
Electrical wiring should only be done by a qualified Electrician per
Local and State Electrical Codes.
MOUNTING
y The pump should be mounted in a dry place and away from any
source of heat. If an enclosure is used, special instructions for
cooling the motor may be necessary. Consult the Factory.
y Do not subject the pump to extreme high or low (freezing)
temperatures while in operation. (Operating ambient temperature
range is 32ºF to 115ºF).
y The pump may be mounted horizontally with the outlet port on the
right when viewed from the pump end or with the pump above the
mount; or vertically with the pump above or below the motor.
PLUMBING
y The pump is equipped with either a pressure sensing demand
switch, a bypass relief valve, or both which controls the maximum
safe operating pressure.
y We recommend use of flexible tubing with proper pressure rating.
y Pump will prime only if all pressure is relieved from outlet port.
y It is recommended that debris-free liquid be pumped or an in-line
sediment filter (50 mesh) be installed at the inlet side to keep
foreign debris out of the system.
y The pump should always be mounted prior to any components
which could introduce particles to the liquid; thus, preventing them
from entering the pump chambers and possibly causing clogging.
y Avoid any sharp bends which may crimp tubing and restrict flow.
Use 90º elbow fittings if necessary. REMCO provides pumps with
dierent kinds of fittings. Please consult Factory for your needs.
ELECTRICAL
y The PowerRV™ Series Pumps are designed for intermittent duty, but
may run continuously if the motor temperature does not exceed the
recommended limit. Some PowerRV™ Series Pumps are equipped
with thermally protected motors and in case motor temperature
exceeds thermal cut-out rating, pump will shut down and will not
restart until motor cools down to specified temperature. Please con-
sult the appropriate Data Sheet for continuous running parameters,
noting the eect of rapid On/O Cycling (See section below).
y If a power supply is used with the system and the supply is not
furnished by REMCO, it will need to be reviewed for correct
application and approval by REMCO.
Installation Procedure
The basic demand pump is controlled by a built-in pressure sensing
demand switch. When a faucet or valve is opened down stream of the
pump, line pressure drops, thus starting the pump automatically.
Conversely, when the valve shuts, the line pressure increases turning the
pump o automatically. The pressure switch actuates in response to the
pump outlet pressure at a predetermined and preset pressure. The pump
label indicates the pre-set OFF pressures. Typically, the OFF pressure is
accurately set at the FACTORY and the ON pressure is within an
allowable range below that value. In response to the characteristics of
the system in which the pump is installed, such as the flexibility and
length of the tubing, and the faucet or valves and the duration that they
are open, these pressure settings may vary. Therefore, change in
pressure settings is expected with use and over time. If the pump does
not have an integral pressure sensing demand switch (i.e. pump is
operated with an external control), pump will be equipped with a bypass
relief valve (bypass is factory preset).
Read the OPERATIONAL AND INSTALLATION GUIDELINES on the
other side carefully before starting to install the pump. Consult the
Factory if there is any question.
Determine the optimum location for your pump before
proceeding.
y Turn o the fluid supply.
y Cut the flexible tubing in suicient length to avoid any stress on the
tubing or hose where it connects to the pump or the fitting on any
accessory or hose.
y Insert tubing or hose into pump ports. If compression fittings with
threaded nuts are used, insert tubing until it bottoms out in the port
and hand tighten the compression nut until the connection is tight.
Then use a wrench to tighten the nut 1/2 turn clockwise or follow the
wrench tightening instructions provided by the fitting manufacturer.
y The PowerRV™ Series pump is now ready for operation. Open the
inlet valve if any to allow fluid to flow to the pump.
y If the power source is a transformer, plug the appropriate REMCO
supplied or approved transformer into the receptacle and connect
the pump to the transformer. If the power source is not a
transformer, connect the pump to the appropriate power source.
Open the discharge or dispensing valve. Allow water to circulate,
purging any entrapped air.
y The pump will now start building pressure. Operating pressure will
vary with flow rate, flow valve, feed-water pressure and line voltage.
Check for fitting leaks.
y If compression fittings with threaded nuts are used, observe any
leaks after pump has run for approximately 15 minutes. Further
tighten compression nuts approximately 1/8 to 1/4 of a turn on all
fittings in the system. Wait 15 minutes and repeat the leak check.
NOTE: Further adjustments should not be necessary although it may
take several days of operation before all the air has been purged
and the system is stabilized.
y Rapid On/O Cycling must be limited to no more than 6
times per minute, even if the pump is operating in the
Continuous Duty zone. Cycling could cause the motor to
heat beyond the recommended maximum temperature, and
reduce the operational life of the pump and pressure-
sensing switch.
