SECTION 4 Operation
Upon completing all of the generator system
connections outlined in Section 1, Complete
Pre-Commissioning checklist (App. A) and fax to
DEL Industries at 805-541-8459. Once form has
been faxed, call DEL at 805-541-1601 to schedule
commissioning. Your generator is ready for initial
start-up. After start-up, the control system will
automatically cycle the generator on and off as
needed to maintain water quality. Initial system
start-up procedures would need to be followed
again in the event of a safety interlock system shut-
down or an interruption in the main power.
4A. System Start-Up
Start process water circulation to produce 1.
a vacuum in the suction port of the injector.
Open isolation valve in ozone supply line if so
equipped.
Start cooling water and verify flow.2.
Verify that all sensor circuits are properly 3.
connected.
Toggle main circuit breaker to the “ON” position. 4.
Close the door.
NOTE: Door must be closed for the system to
operate.
Push F1 “ON/OFF” button. The system’s cooling
fan will start and the oxygen concentrator will begin
operating, unless a shutdown has occurred within
the past 60 seconds, in which case the system
will start after the 60 seconds has elapsed. After
approximately 5 seconds the output solenoid valve
will open. However, the system will not start under
any of the following conditions:
External control device is not calling for ozone 1.
(indictaed by F3).
The system will not start up if the door is not 2.
secured. A door interlock switch is incorporated
into the enclosure to prevent accidental
exposure to high voltage components.
The system will not start up if there is not 3.
enough or too much vacuum being generated
by water flow through injector.
The system will not start up if there is not 4.
enough coolant water flowing through the
generator.
The system will not start up if the oxygen 5.
concentration is not at least 80%.
The system will not start up if the ambient air 6.
temperature is greater than 105°F (41°C).
4B. Cooling Water
If you experience complications, see
TROUBLESHOOTING Section 7 or call 1-800-676-
1335 for assistance. If cooling water flow is not
detected by the flow sensor within 30 seconds after
start up, the system will go into shut down mode.
The cooling fans and oxygen concentrator will
remain on for 30 seconds and then shut down. If
water flow is detected by the flow switch, the ozone
generator time delay circuitry will be activated, and
the ozone generator will start up after a 5 minute
delay.
4C. Feed Gas Flow System Preparation
The oxygen concentrator systems are factory set to
optimal values and should not require adjustment.
