HYDRAULIC CONNECTIONS
Solvent Inlet Lines
For each solvent pump, the standard accessory package contains an inlet line fitted with a
20µm inlet filter.
Connect the inlet line to the inlet tee. The filter goes in the solvent bottle.
Air entering the hydraulic circuit would adversely affect the flow rate. Make sure that all
connectors are correctly seated and properly tightened.
To ensure the connectors are seated and properly tightened:
1. Remove the plastic plug from the inlet of each head.
2. Check that the reverse ferrule is correctly seated at the end of the tubing.
3. Connect the solvent inlet line to the inlet tee.
When screwing or unscrewing the white
connector, secure the tubing with one
hand and slide the connector down.
Make sure the ferrule touches the female
port while sliding the connector down to
prevent the line from twisting.

4. Check that the connectors are tight enough to
prevent air from entering the hydraulic lines.
5. Thread the solvent line through the port on the door
before placing the inlet filter in the appropriate solvent
bottle.
6. Clip the solvent lines to the tray. Push the tubing into the
fissure on the clip before placing it in the appropriate
slot on the tray.
Because of the larger diameter tubing, a dierent
clip is supplied for the rinsing line.
7. Prime the solvent lines prior to operation. Follow the
instructions provided in Priming on page 34 for both
TRILUTION LC and manual control.
