Warranty

The DEL Ozone 50, CMP part EC-20 (PST-42-133-1502), is the corona discharge pool ozone generator earlier sold as the DEL Eclipse 20. CMP rates it for pools up to 50,000 gallons at a nominal 0.5 g/hr of ozone from DEL's Advanced Plasma Gap (APG) cells. It mounts on the wall, runs off the pool timer with the pump, and a venturi injector in the return line draws the ozone into the water under vacuum.

Why PST Customers Pick This

Advanced Plasma Gap Cells

DEL's APG corona discharge cells make the ozone. CMP says APG cells last up to 5 years without significant reduction in output, and the current APG 2 cell doubles the output per cell.

Works With Your Chlorine

CMP pairs DEL ozone with a residual chlorine sanitizer. It says ozone breaks down chloramines and estimates the pool's chlorine demand drops by 60 to 90 percent, based on its extrapolated performance data.

Runs Under Vacuum

A venturi injector manifold in the main return line draws the ozone and air out of the generator, so the unit operates under vacuum. CMP plumbs the injector after the pump, filter, heater and cleaner.

Wires to the Pool Timer

Connect it to the pool timing clock so it runs whenever the pump runs. CMP lists 120/240 V at 0.24 A, 50/60 Hz, with a bonding lug for a No. 6 AWG solid conductor.

Optional MDV for Bubbles

CMP's MDV kit removes ozone bubbles before the water returns to the pool. CMP recommends it to protect pool covers, for indoor pools, and for vinyl liners that fade around the ozone outlet.

Simple Yearly Service

Replace the ozone tube assembly (9-0770-01, tube and check valve) and the ozone module filter (9-0858-01) every year, and each ozone module (9-1636-01) after 15,000 hours. CMP voids the warranty if these are skipped.

Electrical and Ozone Safety

CMP calls for permanent electrical connections by a qualified electrician and GFCI protection, with the generator mounted at least 1 ft above the maximum water level and at least 5 ft from the pool wall. Do not inhale the ozone gas this unit produces.

Frequently Asked Questions

What size pool is the EC-20 for?

CMP rates the DEL Ozone 50 (EC-20) for pools up to 50,000 gallons, used alongside a residual chlorine sanitizer. DEL's Eclipse 20 literature put it at 15,000 gallons as primary sanitation and 50,000 gallons as supplemental sanitation.

Is the DEL Ozone 50 the same unit as the Eclipse 20?

It is the same model line under a new name. CMP sells part EC-20 as the DEL Ozone 50, also known by its earlier name, Eclipse 20. Both are listed at 0.5 g/hr nominal output, wall mount, UL and cUL certified, with a 7.8 x 14.1 x 3.2 in. cabinet. CMP lists updated APG 2 cells on the current version.

Where does it go in the plumbing?

The injector manifold goes in the main return line after the pump, filter, heater and cleaner. CMP says to plumb a cleaner tee before the injector, put the injector after any erosion feeder, keep it on a different return leg than an in-floor cleaning system, and avoid legs with high back pressure such as fountains.

How should the water be prepared before start-up?

CMP says to backwash or clean the filter a day before, superchlorinate, adjust pH to 7.4 to 7.6 and total alkalinity to 80 to 120 ppm, and run filtration for 24 hours before starting the ozone system.
