2 SAFETY TIPS
Before operating your lifter pump, please review these safety tips.
FUEL
WARNING:
Never use any fuel other than clear or red dyed
ASTM D3699 1-K Kerosene or ASTM D396
No.1 or No.2 Fuel Oil. NEVER USE GASOLINE
or other flammable liquid! Use of gasoline can
cause a fire.
OPERATION
1. The maximum lifting height is 26 feet (8 m). (Fig. 1)
2. The height (A) between the lifter and the heater
should be the height specified for the heating appliance.
(16 in. Min., 8 ft.Max.) (Fig. 1)
3. Never close the main tank valve while heater is in
use. If the valve is closed during the lifter operation,
it may cause a pump lock, etc. (Fig. 1)
4. To prevent air locks in fuel pipe, fuel line should be
smooth with no U-shaped or sharp bends. (Fig. 1)
5. Never use the lifter for the purpose other than
supplying fuel to the heaters.
6. This lifter is intended to refuel the heater by means
of gravity pressure difference; therefore, it cannot be
used for a heater which do not have an oil level
control such as oil leveller or solenoid valve.
In the event that the lifter is connected to the sub fuel
tank of a wick fed type heater by mistake, it will
cause an overflow of the fuel on the heater. (Fig. 2)

INSTALLATION
Note : This lifter pump must be installed in accordance with National Fire Protection Association
Code NFPA 31.
This lifter is for indoor installation only. Electrical components are not waterproof.
Also, when used in a cold area, condensation may occur inside the lifter, possibly causing
problems. To avoid such trouble, it is recommended not to install the lifter outdoors or on cool area.
The lifter must be installed in accordance with the National Electrical Code (NFPA 70)
and all other codes that are applicable to the local jurisdiction.
IMPORTANT
This lifter is designed and tested for use with Oil Miser, Toyostove and Toyotomi products.

Funnel SAFETY MECHANISM
1. Overflow Prevention
(a) If the lifter is tilted while in operation, the red lamp comes on and the operation
stops.
(b) If an electric part is in malfunction and the oil level exceeds the normal oil level,
the red lamp comes on and the operation stops.
2. Idle Operation Prevention
If the fuel sump is empty while in operation or if the lifter does not pump up the fuel
because of a pump malfunction, etc.,for more than 20 minutes the yellow lamp comes
on and the motor stops.
3. Continuous Operation Prevention
If the lifter is operated over for 30 minutes due to motor lock, all lamps will flash and the
operation is stopped.
OPERATION When Operating Lifter For The First Time After Installation:
Before operating the lifter in the following procedure, check if installation and piping are
performed in the manner as described in "INSTALLATION" (Page 11~13) and "PIPING" (Page 15~17).
1. Remove the cover screw at the upper side of the cover and remove the cover
bringing it slightly forward.
2. Set the outlet valve lever to CLOSE by pulling up and rotating the lever, turn the operation
switch to OFF position (Fig. 3), and put the power supply cord into the electrical outlet. The
yellow lamp will flash to indicate insufficient oil in the fuel sump.
3. Pour about 0.12 gallons (450 cc) of fuel into
the fuel opening by using the attached funnel.
When the fuel sump is filled sufficiently, the green
lamp will flash to indicate the normal oil level. (Fig. 3)
CAUTION: Use clear or red colored kerosene or
No.1 or No.2 Fuel Oil only!
Be sure there is no contamination
such as dirt, water or other particles.
Note: If an excessive amount of fuel is filled,
the red lamp will flash to indicate excessive
oil level. In this case, set the outlet valve
lever to OPEN and supply fuel to the heater
until it reaches normal oil level. (Fig. 3)

4. Turn the operation switch to ON position. The green lamp will change from flashing to continuous
and the motor will start operating.
CAUTION: Do not touch the motor fan. The motor fan will start at the same time
when turning the operation switch to ON position.

Funnel Note: When first started, the intake line contains air and a muted "THUMPING"
sound will be heard. Once the line is filled with fuel the sound will cease.
Note: If this does not stop until just before the motor stops, air is leaking into the
pipe. Check the pipe and all connections, especially the flares.
Note: If the lifter is installed correctly, a proper amount of fuel will be
pumped up in about 5 to 12 minutes at which time the motor will stop.
5. Turn the outlet valve lever to OPEN.
CAUTION: Be careful not to touch the motor fan when rotating the outlet valve
lever.
6. Remove the funnel from the fuel opening, and then store it in place.
7. Plug the hole of the fuel opening securely with the rubber cap.
8. Replace the cover and attach with cover screw. At this point, the lifter is ready
to perform automatic operation to supply fuel to the heater. When Restarting The Lifter In The Next Season:
1. Remove the cover screw and remove the cover.
2. Turn the outlet valve lever to CLOSE, turn the operation switch to OFF, and put the
power supply cord into the electrical outlet.
3. Turn the operation switch to ON.
Note: If the red lamp comes on or flashes when the operation switch is OFF position, the
motor does not rotate when turning the operation switch to ON.
(a) If the outlet pipe is longer than 33 ft. (10 m),
turn the outlet valve lever to OPEN and CLOSE
repeatedly several times. When the motor starts,
set the outlet valve lever to CLOSE, and when
the motor stops, set it to OPEN. (Fig. 4)
(b) Before turning the outlet valve lever to OPEN,
quickly repeat the procedure of holding up
the lever fully and turning it to CLOSE four or
five times. To prevent air lock which may
occur in the pipe.
(c) Be sure that fuel is not leaking from any
part of the lifter as well as from the inlet/outlet
pipes and all joints.
