Rigid Injector Manifold: This Manifold is equipped with
a DELCheck
TM
spring loaded valve. It cannot be adjusted,
but provides a wide operating range. If more gas fl ow
is necessary, verify that other valves in the system are
not inhibiting fl ow through the Manifold.
If you experience complications see TROUBLE SHOOT-
ING Section 4D.
3. Remove fl owmeter after setting fl ow.
3D System Shut-Down
The following sequence of steps must be followed for servicing
or for storage.
1. Disconnect the power to the ozone generator.
2. After the generator has been shut down, the pool water
circulation pump may be turned off.
3. If the system is to be shut down for an extended period,
disconnect the Ozone Gas Line from the ozone genera-
tor.
3E Water Chemistry
Regular chlorine or bromine testing should be performed as
normal. Ozone will be eliminating the majority of contami-
nants. Therefore, only a small amount of chemicals will need
to be added - just enough to maintain a minimum of residual
level of 0.5 - 1.0 ppm chlorine or 1.0 - 2.0 ppm bromine.
Ozone is pH neutral thus minimizing pH adjustments.
SECTION 4 Maintenance and Service
Maintenance and Service
4A System Electromechanical Overview
Refer to Figure 4.
4A-1. Ozone Module: The Eclipse Ozone Generators are
constructed with High voltage Corona Discharge Ozone
Modules. The EC-1, EC-2, and EC-4 have 1, 2, and 4
modules, respectively.
4A-2. Indicator Lights: Each indicator light on the base
of the Eclipse corresponds to one Ozone Module inside the
unit. The EC-1, EC-2, and EC-4 have 1, 2, and 4 indicators,
respectively. A green light indicates proper operation of it's
respective Ozone Module. For red indicators or no indica-
tors, see the Troubleshooting Section.
4B
System Maintenance
4B-1. The green "ozone power" indicator light(s) on the front
of the DEL Eclipse indicate that the ozone power supply is
operating properly. When an indicator light turns red, replace
the corresponding ozone module.
4B-2. Each ozone module should be replaced after 15,000
hours of operation. Even if the green indicator light(s) are
glowing, the ozone module may be producing little or no
ozone after this period of time due to contamination within
the corona discharge ozone chamber.
DEL Eclipse 1, 2, & 4 Corona Discharge Ozone Generators
4B-3. Regularly reinstall and check the fl owmeter for proper
fl ow. Always remove the fl ow meter after confi rming
proper fl ow. Inspect ozone supply tubing for cracks or wear
and replace as necessary.
4B-4. Replace the Ozone Tube Assembly every year or
sooner, if needed.
If there is evidence of water leaking
past the Check Valve toward the Eclipse, shut down the
Ozone Generator immediately and replace the Ozone Tube
Assembly. If water entered the Eclipse, allow the unit to dry
completely before restarting the unit. Evidence of water in
the Eclipse may void the warranty.
WARNING: Do NOT touch the ends of the Ozone Tube
Assembly when replacing. Trace amounts of nitric acid may
be present and could prove harmful if touched or ingested.
4B-5. While operating, check to see if bubbles are enter-
ing the pool. If an MDV is installed, check the MDV for
bubbles.
4C Generator Servicing - Refer to Figure 4
4C-1. Removing the Cover: The Eclipse ozone generator
may be serviced on the wall without disconnecting any of the
plumbing or wiring. Simply remove the cover as follows:
1. Shut down the pool system power, then disconnect power
to the ozone generator.
2. From the Top End-cap of the Eclipse, remove the 2 rear
screws.
3. From the Bottom End-cap, remove the 2 front screws.
See Figure 4 - Do not remove the screws securing the
unit to the wall.
4. Carefully lift and pull the cover off of the Eclipse.
5. Hold the cover and locate the screw connecting the
ground wire to the base. Remove the screw and set
the cover aside. Do not hang the cover from the ground
wire.
6. The Base will remain fi rmly mounted to the wall with the
Ozone Modules fully accessible for servicing.
4C-2. Ozone Module Replacement
The EC-1, EC-2, and EC-4 have 1, 2, and 4 ozone modules,
respectively. The green indicator lights on the front of the DEL
Eclipse correspond from left to right to ozone module number
1 through 4. For the EC-2 and EC-4, the ozone modules are
numbered beginning with number 1 at the bottom.
To replace an ozone module:
1. Open the DEL Eclipse as described in section 4C-1.
2. Disconnect the tubing at both the inlet and outlet of the
ozone electrode.
3. Remove the two nuts that secure the ozone electrode
to the support bracket.
4. Disconnect the plastic power connector between the
power supply and wire harness.
5. Remove the two screws that secure the power supply to
the metal base.
6. Install the new ozone module by reversing the above steps.
