Remco SMOOTHFLO Series Quick start guide

Please read these Operational and Installation Guidelines before installing the SmoothFlo®
Series Pumps. If additional help is needed, please consult the Factory.
CAUTIONS
yWater 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.
yDo not operate the pump above the pressure limitations specified on the data label.
yNever operate the pump in a harsh environment or hazardous atmosphere, since
motor brush and switch may cause electrical arcing.
yDo not pump gasoline or other flammable liquids. Do not use with petroleum
products.
yDo not assume fluid compatibility. If the fluid is improperly matched to the
pumps’ elastomers, a leak may occur
yAs 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.
yAlways 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
yThe 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.
yDo not subject the pump to extreme high or low (freezing) temperatures while in
operation. (Operating ambient temperature range is 32ºF to 115ºF).
yThe 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
yThe pump is equipped with either a pressure sensing demand switch, a bypass relief
valve, or both which controls the maximum safe operating pressure.
yWe recommend use of flexible tubing with proper pressure rating.
yPump will prime only if all pressure is relieved from outlet port.
yIt 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.
yThe 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.
yAvoid any sharp bends which may crimp tubing and restrict flow. Use 90º elbow
fittings if necessary. REMCO provides pumps with dierent kinds of fittings. Please
consult Factory for your needs.
ELECTRICAL
yThe SmoothFlo® Series Pumps are designed for intermittent duty, but may run
continuously if the motor temperature does not exceed the recommended limit. Some
SmoothFlo® 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 consult the appropri-
ate Data Sheet for continuous running parameters, noting the eect of rapid On/O
Cycling. (See section below)
yIf 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.
yTurn o the fluid supply.
yCut the flexible tubing in suicient length to avoid any stress on the tubing or hose
where it connects to the pump or the fitting on any accessory or hose.
yInsert tubing/hose into pump ports. If compression fittings with threaded nuts are
used, insert tubing until it bottoms out in the port, 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.
yThe SmoothFlo® Series pump is now ready for operation. Open the inlet valve if any to
allow fluid to flow to the pump.
yIf 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.
yThe 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.
yIf 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.
yRapid 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.
Servicing
EVERY USE
Run clean water through the pump and
system.
EVERY YEAR
Check system against operating standards.
If continuous duty, replace lower housing
assembly
EVERY OTHER YEAR
Check against operating standards. If
continuous duty, replace motor
EVERY FIFTH YEAR
Replace pumphead
