SHURflo
RV FRESH WATER PUMP
Installation andOperationManual
Shurflo's patented RVFreshWater Pumps fordrinking water were developed to deliver smooth, consistent flow atall ranges of operation, while drawing
lowcurrent.The balanced diaphragm design incorporates precision ball bearings for long life. Each motor is equipped with an integral thermalbreaker
andall units areCEapproved.RV fresh water pumps are enclosed to prevent incidental moisture from entering; however, they arenot intended for envi-
ronments where splashed water is present. When installed correctly, RVFreshWater Pumps provide years of quiet operation.
General Information
Sluirflo water pumps meet the essential health and safety requirements and are in conformity with the EU EMC directive 89/S36/FEC as specified in EN 55014 (1993).
Shurflo realizes that in many instances our pump is being installed as a replacement pump within an existing system. The following guidelines should be considered to
achieve optimum pump operation.
Mounting
The pumpcanbeatthesame level orbelowthewatertank.Itmaybepositioned
abovethewatertankifneeded,asitiscapableora 6 ft(1.8m) vertical prime.
Horizontal inlettubing will allow priming to30ft.(9m).
Consider a dry location that allowseasyaccessifmaintenanceisrequired.The
pumpshouldnotbelocatedinanareaoflessthanonecubicfoot(0.03m)unless
adequate ventilationisprovided.Excessive heat maytriggertheintegralthermal
breakerandinterruptoperation. When thetemperaturedrops,thebreaker will auto-
matically reset and start theoperation.Thepumpmaybemountedinanyposition
If mountingthepump vertically, thepumpheadshouldbeinthedownpositionso
that inthe unlikely eventofa leak,water will notenterthemotor.
Use No.8stainlesssteelhardwaretofastenthepump.Choosea solid surface(thic
plywood) that will not amplify pumpoperation.Themounting feel areintendedto
isolate thepump from themountingsurface;overtightening,flattening,oruseof
oversized screws will reducethe ability toisolatevibration/noise.
Electrical

Plumbing
Shurflo recommendsatleast1 ft.(0.3m)of1/2"(13mm)I.D. flexible high pressure
tubing tobothports.Ideallythepump'sports/strainer should not beconnectedto
plastic or rigid pipe.Thepump'snormal oscillation maytransmitthrough rigid
plumbing causingnoise,andpossiblyloosenorcrackcomponents.
Installation ofa 50meshstrainerisrecommendedtopreventforeigndebris from
enteringthepump.
The Shurflo In-Line Strainer(1/Band2/B)hasa twist-lock feature allowing simple
cleaning whenplumbed with flexible tubing.

sized stainlesssteelclampstopreventleaks.Never use Teflon tape orsealing com-

• Flow restrictorsin taps andshowerheads.
• Small I.D. lines. Pipe/tubingshouldbeatleast1/2"(13mm)I.D.formain lines.
• Restrictivefittingsandconnections(elbows, "T's", feederlinestolaps,etc.)
