SHURflo Revolution 4008 Installation & Maintenance Manual

Installation & Maintenance Manual
Installation Preparation
The goal of installation is to provide a quiet, easy-
to-maintain installation with good flow and low
backpressure. This can be accomplished with
the following guidelines:
• Mount on a solid surface in an accessible
location for strainer cleaning and pump main-
tenance.
• Use flexible high-pressure hose on the pump
inlet and outlet [such as SHURflo Kit 94-591-
00]. The pumps ports and strainer should not
be connected to plastic or rigid pipe, or the
pump's normal motion will transmit through
rigid plumbing causing noise, and possibly
loosening or cracking components.
• Pump must use an adequate 50-mesh strainer
[such as SHURflo 255 series strainers].
• Use a minimum of 1/2" [13mm] Inner Diame-
ter plumbing. Smaller ID plumbing will cause
cavitation, high backpressure, low flow and
noise.
• No need for an accumulator with by-pass pumps.
• Pump is designed for intermittent duty only: Do not use these pumps for running a Reverse-Osmosis [RO] Filtration
System. High pressure-continuous duty usage will shorten the life of the pump and is not covered under warranty.
• Wire Size is 16 GA MINIMUM , 12GA is recommended---See Wire Chart in Electrical Section for minimum sizing.
• Minimum power requirement is a 10 Amp circuit.
• Reduce restrictions on inlet and outlet. This includes small inner diameter shut-off valves, winterizing valves and
elbows.
• If the RV has an Intellitec Pump Controller, it must be rated at 10 or 15 amps; If the controller is rated at 7.5 Amps, a
new controller or a high-amp relay must be used.
Mounting
• Mount the pump within 6 feet of the tank for best performance and pump life. The pump will pull farther, but the farther it
pulls the more work it does, increasing vibration and noise, and reducing the output and pump life.
• Mount pump in a space of at least 1 cubic foot for adequate ventilation to prevent overheating.
• Pump may be mounted in any position.
• Mount pump for easy access for cleaning strainer, maintenance and service.
• Mount pump on a solid surface to prevent vibration and noise.
Electrical
• The pump works best on an individual filtered circuit, protected by the recom-
mended fuse or breaker specified on the label.
• A 15-Amp switch is recommended and should be on the positive lead.
• Wire Sizing: Proper wire sizing is required for good pump operation. If the
wire is too small, low voltage will affect the pump performance and can create
a fire hazard.
SHUT OFF POWER TO THE PUMP WHEN LEAVING THE RV UNATTENDED.
Plumbing
Installation of a strainer is required to prevent debris from entering the pump.
For noise and vibration reduction we recommend at least 18 in. [.5
both ports. The pump ports and strainer should not be connected to plastic or rigid pipe. This hose should be anchored
where it meets the hard plumbing to reduce plumbing vibration.
