Assembly; Preparing Processor For Operation; Operating The Equipment - Microfluidics Microfluidizer LM20 User Manual

3.8.3 Assembly

Assemble optional and/or shipped loose components to the LM20
1. The inlet reservoir should be assembled. The O-Ring for the glass reservoir must be lubricated
prior to installing the glass reservoir into the metal adapter.
2. Chamber and piping should be assembled. Tighten all high pressure fittings per applicable
drawing contained in the turn over documentation.

3.8.4 Preparing Processor for Operation

1. Turn on the electrical disconnect switch. Allow the system 30 seconds to power on.
2. Fill the inlet reservoir with water.
3. Check for proper hydraulic oil level in the oil reservoir.
4. Check accumulator for nitrogen charge.
!
CAUTION: Do not operate the LM20 with low oil level. System damage will occur.
1. Turn on electric motor.
2. Turn on intensifier.
3. Check motor rotation. The hydraulic pressure gauge will build pressure. If no pressure is
indicated, make sure snubber valve is open.
4. If the motor is rotating in the wrong direction, change any 2 of the 3 power leads.
!
WARNING: REMOVE ALL ELECTRICAL POWER FROM MICROFLUIDIZER BEFORE CHANGING THE
ELECTRICAL WIRING.
5. Prime the pump. See section 3.9.1
6. Set process pressure to 10,000 psi.
7. Run the system for 5 minutes to purge the hydraulic system of air. Keep the inlet reservoir full of
water during this time. If the pump runs dry, it will be necessary to repeat the priming
instructions.
8. The processor is now ready for operation.

3.9 Operating the Equipment

1. Check proper utilities are available and connected to the processor.
2. Ensure the Product Inlet Reservoir is filled.
3. Turn on the electric motor with the "Motor On" button.
4. Prime the intensifier pump. See section 3.9.1
5. Input the desired process pressure on the operator interface screen.
6. Press the "Start Intensifier" button on the operator interface screen. The intensifier pump will
start cycling.
NOTE: The liquid that was inside the equipment after last use may still be present at this point
and will have to be eliminated first.
7. After desired volume of product has been processed or inlet reservoir is empty, press the "Stop
Intensifier" button on the operator interface screen.
8. Turn off the electric motor with the "Motor Off" button.
