The Vacuum Equalizer can automatically turn up to 4 pumps “ON” and
“OFF” depending on the vacuum demand. If a single pump turns "ON"
and "OFF" three times within an hour, that pump will be locked into the
“ON” position for another hour before returning to normal operation.
The Vacuum Equalizer is also equipped with 4 bypass switches to man-
ually turn the corresponding pump “ON”.
When the Vacuum Equalizer is turned “ON” the primary pump is cho-
sen. Each time the unit is turned “OFF” then back “ON” the primary
pump changes to the next pump in sequence. This allows each pump to
have more equal run times.
Note:
Allow 6 Inches for Wiring
Connections on Left Side.

Installation
The Vacuum Equalizer is designed for easy flexible installation. It can
be mounted to a wall (preferred) or simply laid flat on a sturdy level
surface. The unit also provides adaptable wiring options. It can be hard
wired directly to AC mains or connected using an optional line cord kit
(P/N 56106). Either way the connection is made, the wiring can be
routed to the side, bottom, or back of the unit via one of three panel
knockouts provided.
Wall Mounting
Refer to the figure below and mount he Vacuum Equalizer to the wall
by performing the following steps.
1. Find a suitable location for the unit.
2. Use Wall Mount Template P/N 56108 to locate position for the 3
mounting holes.
3. Drill three 1/4” holes at designated position for #10 Anchors.
4. Screw unit to wall using supplied Anchors and Screws.

Pump Setup
Open front cover by turning the two Door Retaining Screws 1/4 turn
counter clockwise. Each pump in the system should have its two wires fed
through a strain relief on the side of the unit starting with pump 1. Once
the wires are through the strain relief they should be tightened down in
the Terminal Block for the corresponding pump. Refer to Pump Select in
the Changing Settings section if you have more than (2) pumps in your
system.

Instructions for using the Vacuum Equalizer with VacStar & STS units:
1. The vacuum relief valve on all units controlled by the Vacuum Equalizer
must be set to the same vacuum level. Set vacuum relief valve on each
unit using the same vacuum gauge.
2. The vacuum relief valve on the pumps must be set higher than the
high vacuum setting of the Vacuum Equalizer. (i.e. if the high setting
on the Vacuum Equalizer is set to 9 in-Hg the vacuum relief valve on
the pumps should be set to 10 In-Hg).
3. The low vacuum setting on the Vacuum Equalizer can be set to 6, 7 or
8 in-Hg, depending on what the end user requires.
4. The delay on and delay off time settings of the Vacuum Equalizer can
be set to their lowest values for the greatest electric and water savings.
Note that if a pump turns “ON” and “OFF” three times within an
hour it will stay powered on for an additional hour before returning to
normal operation. If this happens repeatedly it may be beneficial to
increase the delay off time to prevent this from happening.
Instructions for using the Vacuum Equalizer with VacStar NEO units:
1. Up to four VacStar 20 NEO or four VacStar 40 NEO or two VacStar
50 NEO or two VacStar 80 NEO unit can be controlled by the Vacu-
um Equalizer.
2. All the units must be the same. Do not mix VacStar NEO models.
3. The vacuum settings on all the VacStar NEO pumps must be set to the
same value.
4. The vacuum setting on the VacStar NEO pumps must be set to 1
in-Hg higher than the high vacuum setting of the Vacuum Equalizer.
(i.e. if the high setting on the Vacuum Equalizer is set to 9 in-Hg the
vacuum setting on the VacStar NEO should be set to 10 In-Hg).
5. The low vacuum setting on the Vacuum Equalizer can be set to 6, 7 or
8 in-Hg, depending on what the end user requires.
6. The delay on and delay off time settings of the Vacuum Equalizer can
be set to their lowest values for the greatest electric and water savings.
Note that if a pump turns “ON” and “OFF” three times within an
hour it will stay powered on for an additional hour before returning to
normal operation. If this happens repeatedly it may be beneficial to
increase the delay off time to prevent this from happening.
