5) When the vacuum reaches 2 psia, close the vacuum ON/OFF ball valve.
6) Monitor the vacuum level on the HMI.
If the vacuum level drops quickly, then you have a leak somewhere in the system. Most
likely at one of the points where the assembly parts where installed in STAGE 5:
ASSEMBLE AV30
If the vacuum level drops very slowly (.1 psia every 5-10 seconds) this is acceptable.
STAGE 8: CLEAN SOLVENT RUN (VIDEO CALL WITH
TRUSTEEL)
At this point in the installation, the AV30 is ready to have clean solvent run through the
system. TruSteel prefers to have this step completed over a video call.
To be prepared for this stage you should:
·
Have an electrican with you, or someone capable of swapping wires on the PLC.
We may have to change the phasing on the pump motors and the recycle valve
·
Familiarize yourself with certain parts of the AV30
Recycle Valve
Feed Valve
Pre-Heater Sightglass
Feed Pump
Residue Pump
Solvent Pump
On PLC (Hand Mode, Auto Mode)
·
Have tools ready to swap wires in the PLC (
Small terminal block screwdriver
)
·
Have at least 15 gallons of clean solvent ready to feed into the AV30
·
Have collection vessels ready to capture residue and solvent
·
Have your water heater and chiller powered up and verified that they are properly
functioning (providing hot and cold to the AV30)
On the HMI, go to the TEMPERATURE page. The readouts should should hot for the
evaporation side and cold for the the condenser.
Completing this stage will ensure that:
1) The PLC and HMI are properly communicating.
2) All 3 pumps are spinning in the correct direction.
3) The recycle valve is properly functioning.
