Lancer 105 Installation Manual

SHURflo LO-FLO 105 SERIES RV PUMPS

INSTALLATION MANUAL

SHURflo Lo-Flo 105 Series RV pumps are rugged, lightweight, compact and provide the ability to self-prime and
run dry. Standard features include a pressure demand switch, built in 3/8” hose barb ports, flexible mounting feet,
splash proof motor, and thermal protector. All with the security that comes with a UL Recognized Component.

INSTALLATION:

SHURflo Lo-Flo 105 Series RV pumps are self-priming and can be located up to 2.5 feet above the water level.
Horizontal and vertical prime vary depending on the fluid viscosity and pump configuration. The pump can be at
the same level or below the tank.

 The pump should be located in an area that is dry and properly ventilated to prevent heat build-up.

 Use 50-mesh strainer minimum at the inlet side of the pump. Use flexible hose on inlet.

 The pump can 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.

 12 Volt pump must be provided with a 5-amp fuse.

 Recommended wire size is 16 gauge (1.3 mm) or larger wire as determined by voltage drop. Negative (-)

must be connected to a known ground. Ground wire must be the same (gauge/mm) as the positive.
