Vacuum Connections
The Nautilus has a unique vacuum system which allows you to
connect your vacuums in either parallel or in series. Vacuum
connections can be changed quickly, with only a screw driver.
While there is debate on which vacuum alignment provides the best
extraction, this much is true:
• Two vacuums in series: The vacuum lift is increased by 1.6
times the rating of a single vacuum, while the air flow stays the
same as a single vacuum.
• Two vacuums in parallel: The vacuum air flow is increased by
2.0 times the rating of a single vacuum, while the lift says the
same.
Air flow is usually measured in cubic feet per minute, indicated as
CFM.
Lift is usually measured in inches of water column, indicated as
"H2O or "WC.
To connect vacuums in parallel:
1. Connect the discharge / exhaust hose from vacuum #1 to the
exhaust pipe on machine base.
2. Place the rubber stopper into the vacuum inlet port of vacuum
manifold number two.
3. Open vacuum gate valve and attach the Gatekeeper to prevent
accidental valve closure.
When connected in parallel, both vacuums must be running during
cleaning. Vacuums cannot be operated individually.
To connect vacuums in series:
1. Connect the discharge / exhaust hose from vacuum #1 to the
vacuum inlet port of vacuum manifold number two.
2. Place rubber stopper into the exhaust pipe on machine base.
3. Remove Gatekeeper and close vacuum gate valve.
When connected in series vacuums can be operated individually if desired during
cleaning.
Always secure the Gate Valve Open with
the Gatekeeper when connecting the vacuums in Parallel.
Closing the Vacuum Gate Valve with the hoses connected
the Parallel configuration may
cause damage to Vacuum
#2.
