Do not operate with rivets removed from motor case. Explosion resulting in personal injury, death or property damage can occur. Case openings must be sealed to avoid explosion and maintain ignition protected rating. wet the motor. The pump head may be rotated 180° to reverse the direction of flow if desired. Motor with switch assembly meets USCG Electrical Standards (Title 33, Chapter I, Part 183; Subpart I), and ISO 8846 Marine for IGNITION PROTECTION on gasoline powered vessels. SEE WARNING NOTE. PLUMBING CONNECTIONS The Jabsco Reversible Rotary Vane Pump is ideal for transferring diesel fuel. It is self-priming to about three feet and can pump against a discharge head up to twenty feet. With its integral on-off reversing switch, it is ideal for moving fuel between port and starboard fuel tanks. Pump ports have external 1" hose barb and internal 1/2" pipe threads. Use hose that does not kink when bent and with sufficient wall thickness to prevent collapse when used on suction side of pump. Ideally, hoses should be routed so that some fluid will be retained in pump body to wet the rotor and vanes. Wetting the rotor and vanes aids priming. Use a strainer on the intake hose if debris or solids are present in the fluid being pumped. ALL HOSES MUST HAVE AIRTIGHT CONNECTIONS TO ENABLE FAST PRIMING. Explosion hazard. Do not pump volatile liquids with a flash point below 100°F (38°C). Doing so can cause an explosion or fire resulting in injury or death. NOTE: No. 2 diesel fuel has a flash point of 125°F (52°C) [ASTM 0-93]. HEAD CAPACITY TABLE The pump must be mounted in a dry location – the motor is not waterproof and must not be submerged. SELECTION OF A COOL, VENTILATED location will generally extend pump motor life. The unit can be mounted in any desired position. It is best to mount so that fluid dripping from a loose port connection will not * Vectra is a registered trademark of Celanese Corporation ** Ryton is a registered trademark of Phillips Chemical Company Total Head Feet Metres Table shows approximate Head-Flow for new pump.

ELECTRICAL SPECIFICATION ! MINIMUM WIRE SIZES Explosion hazard. If pump is operated in an area containing flammable vapors, wire leads must be joined by insulated mechanical locking connectors. Loose or inadequate wire connections can spark resulting in an explosion. Property damage, injury or death can occur. The Reversible Vane pump should be wired to an overcurrent protected distribution panel fitted with a 20 amp breaker or fuse that is specific to the Reversible Vane Pump circuit. Connect the orange motor lead to positive and the black motor lead to negative. Fuse Size Wire Length...
