Pentair SHURFLO 802X Serie Manuel D'installation Et D'utilisation page 2

The 802X series pumps are generally self-priming. Horizontal and vertical prime vary depending on the fluid viscosity and pump
configuration.
The pump should be located in an area that is dry and provides adequate ventilation. If mounted within an enclosure, provisions to
cool the motor may be necessary. Heat sinks which attach to the motor are available from SHURFLO if increased heat dissipation is
necessary.
CAUTION DO NOT locate the motor near low temperature plastics or combustible materials. The surface temperature of the motor
may exceed 250°F (120°C).
The pump may be mounted in any position. However, if mounting the pump vertically, the pump head should be in the down
position so that in the event of a leak, fluid will not enter the motor.
Secure the rubber feet with #8 hardware. DO NOT compress the feet; doing so will reduce their ability to isolate vibration/noise.
Use flexible high pressure tubing, compatible with the fluid, to connect the inlet/outlet ports. Tubing should be either 3/8" or 1/2"
(10 or 13 mm) I.D. and at least 18" (46 cm) in length to minimize stress on the fitting/ports and reduce noise. Allow for the shortest
possible tubing route and avoid sharp bends that may kink over time.
Installation of a 50-mesh strainer is recommended to prevent foreign debris from entering the system. Failures due to foreign debris
are not covered under warranty.
NOTE A restriction on the inlet may cause vacuum levels to reach the fluid vapor pressure, causing cavitation, degassing, vapor lock
and a loss in performance. If a check valve is installed, it must have a cracking pressure of no more than 2 psi (.14 bar).
NOTE SHURFLO does not recommend the use of metal fittings or rigid pipe to plumb the inlet/outlet ports. Standard plastic male
and female threaded fittings can be acquired at commercial plumbing supply stores. SHURFLO also distributes swivel barb fittings
and special fittings through SHURFLO dealers.
3/8" Female NPT Models: In some cases, the ports may require a suitable thread sealer applied sparingly. DO NOT over-tighten,
maximum torque 3.7 ft-lbs. (45 in-lbs.) [5 Nm].
1/2" Male-Threaded Models: They are intended to be used with SHURFLO swivel barb fittings, which seal with an internal taper
when hand tightened ¼ turn after contact. Standard ½" NPT fittings may be used when tightened to a maximum torque of 3.7 ft.-lbs.
(45 in-lbs.) [5 Nm].
CAUTION Sealers and Teflon tape may act as a lubricant, causing cracked housings or stripped threads due to over-tightening.
Care should be used when applying sealers; it may enter the pump inhibiting valve action, causing no prime or no
shut-off. Failures due to foreign debris are not covered under warranty.
Snap-Lock Models: The slide fittings are open when the slide is moved out toward the switch. Fittings should be inserted flush
against housing port before the slide is moved to the locked position. Barbed fittings of nylon or polypropylene are available in
various sizes.
The pump's power cord plug must only be connected to a grounding-type receptacle (wall outlet).
CAUTION Electrical outlet (receptacle) wiring should be performed by a qualified electrician, in accordance with all local electrical
codes. Circuit protection is dependent on the individual application requirements. Failure to provide proper circuit
protection may result in a motor failure, which is not covered under warranty.
Improper duty cycle and/or rapid start and stop conditions may cause the internal thermal breaker or fuse to trip, or can result in
premature motor failure due to excessive heat.
