ELECTRICAL CONNECTIONS
DO NOT install anything that will interfere with equipment access or rating plate.
m
BEFORE STARTING
1. Set all associated electrical switches, controls and disconnect switch to “OFF” position.
2. Tighten all electrical connections.
3. Confirm all shipping materials have been removed. See any supplemental instructions to help
identify possible locations.
4. Confirm voltage is within ± 10% of rating plate. If not, contact the installing electrical contractor
and have the voltage condition corrected before continuing.
MAINTENANCE
Warning:
This unit contains high voltage circuits. Electrical shock or death could occur if
instructions are not followed. This equipment contains moving parts that can start
unexpectedly. Injury or death could occur if instructions are not followed. All work
should be performed by a qualified technician. Always disconnect and lock out
power before servicing. DO NOT bypass any interlock or safety switches under any
circumstances.

The effectiveness of the GH generator head is a function of its ability to convert oxygen (O2) to ozone
(O3) through high voltage corona plates. It is essential to maintain airflow through clean corona plates.
Dirty filters will not only reduce the oxygen across the corona plates, but also can change the air
balance. To provide a maintenance history, it is recommended that the owner have a maintenance
file.
The following maintenance instructions are to be carried out by qualified service personnel.
MAINTENANCE SCHEDULE
Every installation is different. Therefore, a maintenance schedule needs to be established based on
each installation. An initial two-month or 1400 hour inspection must be performed. If the filters and
plates are found to be dirty, clean and replace and adjust the maintenance schedule accordingly. A
review of the installation should be performed to find the source of the contamination.
Note: Seasonal changes may affect the maintenance requirements. Adjust the schedule accordingly.
The maximum time between maintenance checks should be 6 months.

ELECTRICAL
1. Check all wiring for loose connections.
2. Check voltage at unit (while in operation).
3. Check amperage draw against unit rating plate.
CORONA PLATES
Disconnect the power from the unit. Locate the generator head(s) and remove the cover. Each
generator head has up to 6 corona plates. Locate the corona plates. Slide them out of their locating
grooves and clean. All plates must be cleaned at the same time.
Plate Cleaning:
The oxidizer includes a second complete set of corona plates when delivered new. Alternate plate
usage between the two sets. Clean the dirty corona plates by using a dishwasher or hand wash. If
cleaning by hand, begin cleaning the plates by spraying or dipping them in cleaning solution. The
cleaning solution should be a detergent product that is capable of breaking down oils and greases but
leaves no residue when rinsed off. If the plates are rinsed in hard water, then clean compressed air
should be used to dry off of the corona plates to prevent hard water deposits.
CORONA PLATE INSPECTION:
After cleaning, inspect each corona plate for pin holes or other damage. A pin-hole in the plate will
cause the generator head(s) to operate incorrectly. Holes or cracks should not be visible on the plate.
Replace any corona plates that fail inspection.
After the plates have been checked, reinstall the cover.
