Installation and maintenance
Installation
General: Pump may be mounted in any position without loss of efficiency; however, it is suggested that
the pump head be down if vertical mounting is desired. Mount motor as close as possible to power
source to obtain full voltage.
The pump should be installed so that the motor is protected from rain or wash down.
When using a vac-on-switch, mount it on the connection on the inlet side of the pump. When using a
pressure switch, mount it on the outlet side of the pump.
F3B-19 Oil Change: Locate the pump near the engine so the length of the hose to the engine can be
kept as short as possible. To achieve best operation the pump should be installed at the same level as
the maximum level of oil in the engine. Mount the provided 3/8” gate valve between the engine and the
pump as a safeguard against accidental oil discharge during operation or draining. Use a reinforced oil
hose that can withstand 120°C for connection between the pump and oil receptacle. Note! The hose
between the motor and pump must use permanent connections.
Operation: F3B19-Oil Change: Before changing the oil, run the engine and let the temperature rise to
50°C to reduce the viscosity. This makes it easier to handle the oil. Turn off the engine. Open the gate
valve between the motor and pump. Make sure the discharge hose is securely positioned in a waste oil
receptacle. Note that the discharge hose may tend to move slightly during operation. Move the switch

in the flow direction to the receptacle. When the oil is drained (check with the dipstick of the engine)
switch off the pump immediately by moving the integrated switch to its centre position. Change the oil
receptacle to the container with new oil. Start the pump by pressing the switch in the flow direction to
the motor. Use the dipstick of the engine to make sure the right amount of oil has been filled into the
engine. Note! As soon as all oil has been drained from the engine, or when the container for refilling oil
into the engine is empty, the pump must be stopped immediately. Otherwise there is a risk of dry running
which will damage the impeller.

All DC pumps F3B-19 Oil Change
Electrical installation
The pump must be installed according to ISO 10133 (Small craft - Electrical system - Extra low voltage
DC installation for continuous current). Note: The fuse must be ignition protected.
The motor is equipped with built in thermal protection to prevent the motor from overheating. The
protection is automatically restored when the motor is cooled. If the pump is connected with separate
earth lead, this should be yellow/green and connected to the motor base. See the wiring table above for
correct installation. Negative wire must be black.
Choose wire size in accordance with total wire length (see table above). The wire connections must
be sealed with a marine sealant or sealed cable connectors.Other electrical devices, eg switch, circuit
breaker, must be installed between the pump and the positive (+) lead on the battery (on the red wire).
Note: Before installation with electrical control systems, check that equipment to be used is of sufficient
rated capacity to accept ampere draw of motor. Low voltage will cause motor to overheat.

Self-priming
Pump is self-priming up to 3m (for F4B 4 m). Intake lines must be air-tight to ensure selfpriming.
Note: Pump will prime when impeller is dry but suction lift up to 3m (for F4B 4 m) is only obtainable
when impeller is lubricated with liquid being pumped or Johnson Impeller lubricant.
For permanent installations where suction lift exceeds 4 m, a foot valve should be used to assure priming
on start up.
Continuous duty
For continuous duty 0,6 bar (60 kPa) maximum head is permissible. Normal working temperature of the
motor may reach approx. +80°C (surface temperature) which may burn your skin.
Varning! Dry running
Do not run dry for more than 30 seconds. Lack of liquid will burn the impeller and damage the seals.
If the pump is used for fuel oil transfer it should be equipped with a vacuum switch. When the liquid has
been evacuated the electric supply is automatically switched off.
Varning! Caution Explosion Hazard
Do not pump gasoline, solvents, thinners, highly concentrated or organic acids. If corrosive fluids must
be handled, pump life will be pro-longed if flushed with water after each use or after each work day.
Varning! Caution. Explosion Hazard.
Never operate a motor which in any way has been manipulated and lost it’s full enclosure.
Temperature
Max ambient temperature: +60°C. The life of the impeller depends on the temperature of liquid being
pumped.
Temperatures between +5°C and +55°C give normal life. Higher or lower temperature will reduce the
life.
When the pump is used as bilge pump
Max total head 6 m. The pump must be installed so that the motor is protected from splash from bilge
water.
The pump must be fitted with a strainer or other means of preventing debris from entering the pump.
Freezing weather
Drain unit by loosening the endcover. Glycol based anti-freezes can be used but do not use petroleum
based anti-freeze compounds.
Waste handling/material recycling
At the product’s end of life please dispose of the product according to applicable law. Where applicable
please disassemble the product and recycle the parts material.

Accessories
Vacuum switch 09-45053
•For automatic shut off operation.
•To prevent pump damage.
The vacuum switch works with all selfpriming impeller pumps and should
be used for e.g. bilge pumping/emptying of tanks to prevent the pump
from running dry.
The vacuum switch automatically shuts the pump off when the bilge/tank is
dry. With the switch fitted, you can start the pump by remote push button
or manually by depressing lever on the switch.
Varning! The switch is not ignition protected.
