a)
Attach the A side (red) hose to the A side ball valve and
make sure to keep the ball valve in the upward position
and in the closed position . Tighten to about 30 lb-ft . Do
not over tighten .
b) Attach the B side (blue) hose to the B side ball valve and
make sure to keep the ball valve in the upward position
and in the closed position . Tighten to about 30 lb-ft .
Do not over tighten .
9 . Unroll chemical hoses and remove any kinks in the hose .
a) Attach the shutoff valves to the end of the hoses on the
A and B side . Make sure the arrow on the shutoff valves is
directed towards the gun . Tighten to about 30 lb-ft but do
not over tighten .
b) Attach the gun to the two shutoff valves at the end of the
hose . Keep the ball valve in the upward position and in
the closed position . Complete this for both the A and
B sides .
c) Use black electrical tape to tape the A and B side hoses
together . Start this taping process at the gun end and
work your way back towards the tanks . Tape the hoses
together every 18 inches .
d) Tighten the ball valves to about 30 lb-ft but do not over
tighten .
e) At this point, check to make sure all hose, valve and filter
connections have been properly tightened to assure no
nitrogen or chemical leaks .
NOTE: If a 30' hose extension is required, you will need to attach
a coupling to the end of the hose coming from the chemical tank
and connect the hose sections together . A standard ¼" male flare
coupling from a hardware store works just fine . Tighten to about
30 lb-ft but do not over tighten . Complete for both the A and B
sides (total hose length is not recommended to exceed 120 feet) .
Once the hose extensions have been added, attach the shutoff
valves to the end of the hose extensions where the gun is
connected .
Note: If you are using the Arctic Pak heated hose assembly, it is
recommended that you remove the yellow insulation during the
summer months) from the hoses and store it to prevent wear and
tear on the insulation . This will extend the life of the insulation .
During the colder temperature months, place the yellow insulation
back over the hoses . If you remove the yellow insulation during
the warm weather months, continue taping the A and B side hoses
together every 18 inches . .

3.2 Tank Positioning
1 . Position the "A" tank to the left and the "B" tank to the right .
This is the standard in the polyurethane industry .
2 . Place a nitrogen cylinder between the "A" and "B" tanks .
3 . Secure the nitrogen cylinder to prevent it from falling
if bumped .
3.3 Nitrogen Regulator Information
1 . Remove the orifice protector on the nitrogen cylinder . Insert
the nitrogen regulator assembly stem into the orifice and
hand tighten . Snug firmly using an adjustable wrench .
Be careful not to strip the brass fitting .
2 . Verify that the valve stems are freewheeling . This indicates
that the regulator stems are backed out .
3 . Remove the thread protectors on the bottom of the
nitrogen regulator .
4 . Connect a yellow & red-taped nitrogen line to the left fitting
on the nitrogen regulator assembly . Snug firmly with an
adjustable wrench .
5 . Locate the yellow-coded nitrogen intake valve on the "A"
tank . Verify that the valve is closed . The handle should
be perpendicular to the valve . Loosen and remove the
nitrogen intake cap on the "A" tank .
6 . Connect the other end of the yellow & red-taped-coded
nitrogen line to the nitrogen intake valve of the "A" tank .
Snug firmly with an adjustable wrench .
7 . Connect the other yellow & blue-taped nitrogen line to
the right fitting on the nitrogen regulator assembly .
Snug firmly with an adjustable wrench .
8 . Locate the yellow-coded nitrogen intake valve on the
"B" tank . Verify that the valve is closed . The handle should
be perpendicular to the valve . Loosen and remove the
nitrogen intake cap on the "B" tank .
9 . Connect the other end of the yellow & blue-taped coded
nitrogen line to the nitrogen intake valve of the "B" tank
Snug firmly with an adjustable wrench .
