2. Install the suction oil line (from the the tank to the canister filter):
a. Refer to Figures 4H and 4J. Prepare a piece of 1/2" O.D. copper tubing (user-supplied) which will
function as the pick-up line from the tank to the canister filter. This copper tubing must have the
following specifications:
• The tube must be one continuous piece of 1/2" O.D. copper tubing with no kinks
or fittings.
• The tube is to slant up from the tank to the pump with no loops or high points to
trap air.
c. Locate the 2" MPT x 1/2" FPT x 1/2" FPT duplex, slip-thru hex bushing (which will eventually be
installed into one of the 2" openings on the tank). Note that the fitting is marked "S" for suction
and "R" for return.
d. Install the 1/2" MPT x 1/2" slip fitting into the "S" side of the 2" duplex slip-thru hex bushing.
e. Install the 1/4" MPT x 1/4" compression fitting into the 1/2" x 1/4" brass bushing.
f. Install the 1/2" x 1/4" brass bushing into the "R" side of the 2" duplex slip-thru hex bushing.
g. Measure the height of the oil tank (from the bottom of the tank, NOT the floor) to the 2"
opening that you are going to use for the supply oil line. Deduct 12" (305mm) from this
measurement and transfer this new measurement onto the 1/2" O.D. copper tubing.
h. Remove the locking nut and ferrel sleeve connector from the 1/2" slip fitting, and slide them
over the copper tubing.
i. Slide the 1/2" O.D. copper tubing through the 1/2" slip fitting, which is installed in the "S"
side of the 2" hex bushing.
j. Install the screen into one side of the 3/4" check valve (making sure the arrow is pointing
away from the screen assembly).
k. Install the 3/4" x 1/2" brass bushing into the 3/4" check valve.
l. Install the 1/2" MPT x 1/2" flare adapter into the 3/4" x 1/2" brass bushing.
m. Slide the 1/2" flare nut over the end of the 1/2" copper tubing, and flare the end of the tubing.
NOTE:
Use a high-quality flaring tool (such as a Ridgid Flaring Tool) to ensure that all
flares are made properly (i.e. so they will be 100% airtight).
n. Install the flared oil line and nut onto the assembled check valve/screen and tighten.
o. Pick up the assembled oil line, and carefully guide the end of the tubing with the check valve through
the 2" tank opening.
p. Apply Permatex #2 non-hardening gasket sealer (or equivalent) to the threads of the 2" duplex
slip-thru tank bushing, and tighten this fitting into the tank.
q. Pull the 1/2" copper tubing back up through the slip fitting until you see the mark that you put on the
tubing earlier. Holding the tubing with one hand, push the ferrel sleeve connector and locking nut
down the tubing, then tighten onto the 1/2" slip fitting. The oil line is now installed in the correct
position off of the bottom of the tank.
r. Carefully bend the oil line up to the canister filter; use a spring bender over the oil line while bending
the tubing to prevent kinks in the oil line. Allowing for the flare nut, cut off the excess tubing.
s. Install the 1/2" flare nut onto the tubing, and flare the end of the tubing.
t. Install the end of the tubing with the flare nut onto the 1/2" flare adapter (on the ball valve assembly
at the canister filter).
u. Install a vent from the tank to the outside of the building according to code. The tank must be
properly vented to allow air to enter the tank as oil is pumped out and to safely vent fumes to the
outside. See Figures 4J.
v. Install plugs in all other tank openings as required by code.
w. Inspect the installation. For proper suction oil line operation, make sure all components are
installed and positioned as specified in this manual.
