Assembly Instructions
Operating Instructions
Please read the following before proceeding with installation
and operation of the JohnDow Used Oil Storage System.
Installation:
1. Position the tank in a location that is within 2” of level.
2. Attach the 10’ x 3/4” intake hose to the pump.
3. Install the liquid level gauge in the 2” coupling at the left
read of the tank according to the instructions provided
with the gauge.
4. If required by local regulations, install necessary venting
through the 4” coupling located at the center of the tank.
5. Install the hose hanger by bolting it on the outside of the
tank.
6. Attach air supply to the connection on the rear of the
security cabinet.
7. Install quick disconnect adapter to waste oil drain.
Operation:
1. Position the full waste oil drain next to the system and
connect the intake hose to the drain.
2. Open the valve on the waste oil drain assembly.
3. Turn on the air supply to start the pump and transfer of
used oil
4. When the oil drain is empty - disconnect the hose and
then turn off the air supply.
Automatic Overfill Protection
The JohnDow Used Oil Storage System is equipped with an automatic
air shut-off valve that stops the air supply to the pump to prevent over-
filling and overflowing the tank. The air valve will engage when the tank
is at approximately 85% of capacity.
Do not attempt to override the shut-off valve as this may cause damage
to the valve assembly and result in overflowing the tank. Call your used
oil hauler immediately.
Double-Wall, 110% Secondary Containment
The double-wall tank design provides protection against oil leakage in
the unlikely event the inner tank should fail. The outer tank will contain
over 110% of the volume of the inner tank.
Two coupling on the extreme left end of the tank allows for inspection of
the outer tank containment chamber. Use caution to avoid pouring any
oil into the outer tank chamber.
Security Cover
The security cover protects the pump and shut-off valve from damage.
If it is necessary to remove this cover, the air supply must be discon-
nected from the back inside of the cover first. The quick disconnect air
fittings allow the air hose to be removed by simply depressing the grey
ring around the plastic hose and pulling the hose out. The reconnect,
push the hose into the fitting unit, it is secure.
U.L. Listed 1” Diaphragm Pump
The air diaphragm pump is designed to run efficiently at 60 psi. The air
regulator is pre-set at the factory and should not need adjustment.
If the pump fails to run:
• Make sure the air supply is properly hooked up.
• Make sure the tank is not full and automatic shut-off has cut the air
supply.
If the pump runs but is not pumping oil:
• Disconnect the intake hose from the pump and check for suction at
the hose connection point. If there is suction at the pump, then check
the quick disconnect coupler on the other end of the hose for debris
that could be blocking the flow.
• If there is no suction at the pump, call our Service Department at
1-800-433-0708
for help.
CAUTION:
Before attempting to transfer oil, always check the tank level
to determine if sufficient capacity is available. This will pre-
vent possible overfilling of the tank. Call your authorized
used oil hauler to evacuate the tank.
