3. Check that the o-ring is in place on the barbed
fitting (73b). Apply low strength thread adhesive
and install the fitting in the upper throat cartridge
port. Be sure the other two ports are plugged
(73d).
4. Catalyst (35 cc) pumps: Repeat for the lower
throat cartridge.
5. If you are lubricating the dosing valves, remove
the plug (73d) and gasket from the valve port (V)
closest to the TSL cup.
NOTE: Choose the valve port in the upward
facing position. This will allow liquid to flow into
the valve while allowing air to rise out of the
valve.
Check that the o-ring is in place on the barbed
fitting (73b). Apply low strength thread adhesive
and install the fitting in the valve port (V).
NOTE: Do not confuse the valve port (V) with the
air port (W).

NOTE: If you are not lubricating the dosing
valves, remove the unused barbed fittings (73b)
from the bottom of the TSL cup (73). Apply low
strength thread adhesive and install the plugs
and gaskets supplied with the kit.
6. Cut the tubing (73c) to length as required.
Connect the TSL cup fittings to the fittings on the
pump and valves. TSL is gravity-fed from the
cup to the pump and valves; position the fittings
and tubing to prevent kinks and enable the TSL
to flow freely down to the valve and air to rise
up and out of the valve.
7. Fill the cup to the level of the lower black
horizontal line with either TSL or ISO oil, as
appropriate for the resin and catalyst materials
being used.
NOTE: If TSL leaks from the rod guard of the
color (70 cc) pump, be sure the lower u-cup seal
is installed in the lower throat cartridge.
NOTE: The fluid levels in the TSL cups should be
checked daily. Fluid levels should remain static
for an extended period of time. Rising or falling
fluid levels in a TSL cup can be an indication of a
condition which needs immediate attention. Refer
to the troubleshooting steps in the repair manual for
guidance.
