6.0 MECHANICAL INSTALLATION
Only qualified technicians familiar with local and national
codes should install this equipment. Connect the vacuum
lines as shown on the installation drawings. Connect the
compressed air (80 - 120 psig) to air actuated valves as
required.
Locate the pump where it can be interconnected with the
vacuum system piping easily.

6.2 Regulator Warning
The compressed air regulator has
been set at the factory to allow the
vacuum breaker to relieve at the
specified vacuum.
Tampering with the
regulator will void the warranty.
Only
qualified Novatec service personnel
may adjust the relief point via regula-
tor pressure.

Accommodations should be made to allow full access of
the pump for service, especially the belt guard, starter,
filter, vacuum breaker valve, vacuum blower and vacuum
relief valve. The vacuum gauge should be visible, but can
be carefully rotated in its fitting as required. The pump
6.3 Combination Vacuum Breaker and Vacuum Relief Valve
should be secured to
the floor to prevent
movement from vibra-
tion and isolating pads
(not supplied) may be in-
stalled to minimize noise
transfer to the floor, if
desired.

The Novatec vacuum breaker valve for system seek
operation also serves as the vacuum relief valve to
regulate the
pump’s
workload. The dual functionality is
accomplished by utilizing an equilibrium of compressed
air pressure and vacuum level in conjunction with the
vacuum breaker action, governed by the system
’s
conveying control panel.
NOTE: Specifications will be reduced for standard pump
assemblies running on 50Hz. Information shown is for
standard VPDB vacuum pumps. Refer to special job
tem’s cyclone dust collector and is commonly connected
directly to the cyclone lid with rigid tubing or flex hose. It
is convenient to service the dust collector and the pump
filter at the same time.
6.1 Compressed Air Supply
Clean compressed air should be supplied to the VPDB
pump’s vacuum breaker valve regulator, providing 80 to
120 psig. A filter (not supplied) should be provided if the
cleanliness of the air is questionable.

6.4 Discharge Selection Valve (DSV)
Pump exhausts to atmosphere or can be pipe outside of
pump room.
•
Requires a separate Relief Vent in a closed system.
•
Includes 3-Bolt Coupler and pump adapter fitting.
•
For use with either VRB or VPDB pumps.
6.5 Closed Loop Relief Vent (CLR)
Provides Pressure Relief in a Closed Loop Conveying
System.
•
Install near take-off devices in a closed loop system.
•
Install one per row of take-offs that share a common
closed loop manifold.
