Section I Installation
All wiring between the main control box and equipment should be Class B, low-
voltage. In most cases, a conduit is
Before proceeding with any electrical installation, comply with and
maintain all applicable local electrical code(s) and regulations.
1. Position the main control mounting box, so that the master control panel switches
can be eye level, in a convenient location (near the office's entrance/exit).
2. Once the main control mounting box is in position, secure it using the brackets
provided.
IMPORTANT NOTE: To ensure proper installation of the finished master control
panel, the mud flange must be recessed by dry wall thickness.

3. Install the main control box wires as follows:
a. Using a hammer and pliers, remove the appropriate knock-out from the main
control mounting box.
b. Fit a nylon grommet in the knock-out. (This protects the wires from chaffing and
shorting out.)
c. Run the appropriate wires to their respective equipment location. Then
connect the wires according to the instructions on the following pages.
4. After all wiring connections are completed correctly, position the master control
panel over the main control box and secure using the screws provided.

Single/Dual Vacuum Pump Relay Box Connection
(All Panels, Except Turbine)
Before making any wiring connections to the main control box, the vacuum unit
Before proceeding with the single/dual vacuum pump relay box connection, make
sure the electrical power supply to the vacuum pump is turned OFF.
All pumps (single or dual) must have three, low-voltage wires installed from the
top of each relay box going to the main control box in order to operate the master
control panel lighted ON/OFF switches.

Refer to the vacuum pump relay box wiring diagram on the next page.
For dual vacuum pump relay box connection to the main
NOTE: For vacuum pump relay boxes with factory-installed yellow, black and brown
wires, it is not necessary to perform Steps 1 through 8.
1. Loosen the top and bottom retainer screws from the vacuum pump relay box and
remove the cover.
2. Remove the black strain relief grommet from the top of the vacuum pump relay
box.
3. Place the tap connector slot over the yellow transformer wire, and insert the
brown wire into the end of the tap connector.
4. Squeeze the metal connector tight, and snap the attached cover in place.
5. Route the brown wire out through the strain relief grommet hole along with the
yellow and black wires.
6. Reinstall the strain relief grommet around the yellow, black and brown wires.
7. Reinstall the relay box cover and tighten the top and bottom retainer screws.
8. Run and connect the low-voltage wires to the main control panel mounting box
according to the applicable wiring diagram in Section II Schematics. (Refer to the
index on Page 8 for the location of the appropriate diagram.)

Section IV Operation & Care
Master Water Control Valve Connection
(With 24-Volt Lighted Control Switch)
— NOTICE —
When using low voltage to operate the master water control valve (MWCV), a 115-
volt electrical receptacle for the MWCV “plug-in” transformer must be supplied.
1. Remove the MWCV from the shipping container or locate a previously installed
MWCV in the office.
— WARNING —
Before proceeding to Step 2, make sure all power is properly disconnected.
2. Dismantle the coil assembly.
3. Replace the 115-volt coil with the 24-volt coil included in the kit.
4. Provide power to the coil assembly using the “Plug-In” 115V/24V transformer
supplied with the kit.
5. Connect the two low-voltage wires from the transformer according to the
applicable master control panel wiring diagram in Section II.
— WARNING —
Do not plug in the transformer until all electrical connections are complete.
6. Test the MWCV and transformer as follows:
a. Turn the light switch to the OFF position. (The light should be off.)
b. Turn the light switch to the ON position. (The light should be on.)
c. When the switch is activated, the MWCV should make a clicking sound, which
indicates the valve is working properly.
d. If the light fails to come on, or if the MWCV fails to function, check all
connections referring to the applicable master control panel wiring diagram in
Section II.
NOTE: If a light stays

Section I Installation
Air Compressor Remote Connection
1. Turn OFF all power to the air compressor at the source.
2. Mount the compressor relay box near the junction box on the air compressor.
3. Connect the power source supply lines to L1 and L2 on the compressor relay box
for new installation.
NOTE: For existing installation, first remove the power source supply lines from
the junction box.
4. Connect conduit from the compressor relay box to the junction box.
5. Connect the two lines from T1 and T2 to the two compressor power lines in the
junction box.
6. Run and connect low-voltage wires to the main control box according to the
applicable master control panel wiring diagram in Section II.
