Requirements
Description of Operation
• The dry vacuum system has a variable speed vacuum pump that reduces electrical consumption. The integrated separator tank and firmware allow for fully
automated operation.
• The vacuum creation and operation is free from water and oil.
• The vacuum motor is controlled by a vacuum sensor connected to the separator tank. The speed of the motor will increase or decrease to maintain the pre-set
vacuum level.
• The vacuum system has an automated tank washdown maintenance cycle that starts within 1 minute of the system being turned off. The washdown solenoid
opens to allow fresh water to spray into the tank, rinsing the tank free from debris. This cycle runs for approximately 1 minute.
• The integrated separation tank has been designed to collect the fluids evacuated during a normal operating day. If an excessive amount of fluids is collected,
the float switch in the separator will stop the vacuum in order for the tank to automatically drain. This process takes about 10 seconds. The vacuum will
automatically restart after the drain cycle.

A-dec DV Dry Vacuum Service Guide Requirements
HVAC Requirements
Adequate cooling air is required. All vacuum models are installed and
operated in a thermostatically or otherwise stable ambient temperature
environment. Forced air and HVAC input are recommended for use in
addition to an exhaust fan if normal ambient temperatures vary from
specified operating temperature range.
The operating temperature range of the vacuum is 40º F to 104º F or 4.4 to
40º C.
Vacuum life is directly affected by the operating temperature.

* Based on 80º F/27º C cooling air available and 100º F/38º C maximum mechanical room
temperature. This does not account for overall mechanical room size and additional heat
sources. Consult an HVAC specialist for proper temperature range.

Turn On/Turn Off Power
NOTE If you turn off the vacuum unit for long periods of non-use,
like an extended office shutdown, ensure that the power remains
connected. The vacuum will automatically turn on, momentarily,
every 12 hours to prevent components from seizing. This also helps
extend the life of the motor.

Master Power Switch
The master power switch turns the vacuum on or off. It also overrides the
other remote power functions. If your vacuum is connected to remote LED
push-button controls or a Smart Shield touchscreen, this switch should be in
the REMOTE position.
LED Push-Button Controls
If you have LED push-button controls, press the button once to turn the
vacuum unit on or off. Blue LED lighting indicates that the vacuum is on. If
the LED does not illuminate, check and verify that the master power switch on
the vacuum is in the REMOTE position.

Optional Smart Shield Touchscreen Controls
For congurations with the Smart Shield
touchscreen, use the power switch icon at the
bottom of the screen or tap the VAC icon to turn
the vacuum unit on or off. If the Smart Shield does
not operate, check and verify that the master power
switch on the vacuum is in the REMOTE position.
For more information on the touchscreen, see
“Smart Shield Touchscreen Controls” on page 8.

Vacuum Gauge and Operation
Vacuum Gauge
The vacuum gauge is located next to the master power switch on the top panel
Vacuum
Gauge
of the vacuum. This gauge provides a real-time level of the negative pressure
inside the separator tank. The DV dry vacuum is factory preset to maintain
10 inHg (34 kPa) during normal operation.
Vacuum Startup and Normal Operation
At initial startup, the vacuum motor runs until the system reaches the factory
preset of 10 inHg (34 kPa). As vacuum instruments are opened and closed, the
motor rpm will increase or decrease (depending on demand) to maintain that
level.
NOTE You may hear the vacuum motor frequently speeding up
or slowing down as it compensates for various levels of demand.
This is normal. However, if the motor does not slow down after
all vacuum instruments are closed, or if your system is unable to
consistently maintain 10 inHg (34 kPa), see “Troubleshooting Tasks”
on page 22 or contact A-dec Customer Service.

Separator
Tank
Washdown
Waterline
Separator Tank Drain and Washdown Cycles
The vacuum removes liquid from the air and collects it in the separator tank.
When more than 10 gallons (38 L) are collected, a float switch in the tank stops
the vacuum and drains the tank. Once the water level drops and the float
switch turns off, the vacuum will turn back on in about 10 seconds.
To manually initiate the drain and washdown cycles, you must turn off the
vacuum. Combined, both cycles take less than 2 minutes. A-dec recommends
that you turn off the vacuum to activate this process at least once a day. For
more information, see “Regular Maintenance Tasks” on page 19.
