Setup

NOTICE
Proper system setup, startup, and shutdown pro-
cedures are critical to electrical equipment reliabil-
ity. The following procedures ensure steady
voltage. Failure to follow these procedures will
cause voltage fluctuations that can damage electri-
cal equipment and void the warranty.
1.
Locate Reactor
a. Locate Reactor on a level surface. See Dimen-
sions, page 39, for clearance and mounting
hole dimensions.
b. Do not expose Reactor to rain.
NOTICE
Bolt Reactor to original shipping pallet before lifting.
c. Use the casters to move Reactor to a fixed loca-
tion, or bolt to shipping pallet and move with
forklift.
d. To mount on a truck bed or tailer, remove cast-
ers and bolt directly to truck or trailer bed. See
page 39.

General equipment guidelines
Determine the correct size generator. Using the cor-
rect size generator and proper air compressor will
enable the proportioner to run at a nearly constant
RPM. Failure to do so will cause voltage fluctuations
that can damage electrical equipment. Ensure the
generator matches the voltage and phase of the
proportioner.
Use the following procedure to determine the cor-
rect size generator.
a. List system components that use peak load
requirements in watts.
b. Add the wattage required by the system compo-
nents.
c. Perform the following equation:
Total watts x 1.25 = kVA (kilovolt-amperes)
d. Select a generator size that is equal to or
greater than the determined kVA.
Use proportioner power cords that meet or exceed
the requirements listed in Table 2. Failure to do so
will cause voltage fluctuations that can damage
electrical equipment.
Use an air compressor with constant speed head
unloading devices. Direct online air compressors
that start and stop during a job will cause voltage
fluctuations that can damage electrical equipment.
Maintain and inspect the generator, air compressor,
and other equipment per the manufacturer recom-
mendations to avoid an unexpected shutdown.
Unexpected equipment shutdown will cause voltage
fluctuations that can damage electrical equipment.
Use a wall power supply with enough current to
meet system requirements. Failure to do so will
cause voltage fluctuations that can damage electri-
cal equipment.
