GENERAL INSTALLATION GUIDELINES
FOR CHEM-FREE MARINE OZONE SYSTEMS
| LOCATION: |
All Chem-Free ozone generators, air preparation devices, as well as any and all associated electrical control/distribution systems or devices must be installed in a location that is as dry as possible. They must not, under any normal circumstance, be exposed to water spray, splash, or immersion. Special care should be taken when installing systems in a bilge area to keep the equipment above and normal water levels that may occur in the bilge. Of equal importance is choosing a location that is capable of supporting the equipment weight under normal sailing conditions, as well as dynamic loading and rough weather conditions while under way.
Chem-Free ozone generating devices may be installed in any convenient position as dictated by size restraints, conditions and area(s) to be serviced by the system demands. However, one should always consider the requirements for service and repair of the installed equipment. There should be sufficient room to open doors and/or remove covers. Alternately, it will be necessary to make provisions for convenient removal the system for service. The same requirements also apply to all Chem-Free air preparation or oxygen concentration devices or systems. Many Chem-Free systems have flow control/gauge units installed to control to meter and monitor the rate of flow. Obviously, and system with a floating ball type flow control must be mounted in a vertical position. Motion of the vessel underway has no effect on the gauges. Special care should be exercised when routing tubing to or from a Chem-Free device or system. Tie wraps, clamps, and any such hanger must not be so tight that the tubing is collapsed. All that is necessary is preventing relative movement of the tubing and clamp/hanger and the resulting chaffing and potential leaks caused thereby. |
| ELECTRICAL: |
Marine grade, tinned, fine strand wire is the preferred type for all power and control wiring of Chem-Free devices or systems. All wiring should be in accordance with local or marine codes and standards of good electrical engineering craftsmanship. Neither Delta Marine International, Inc., nor Chem-Free Marine Ozone Systems assumes any liability or responsibility for damage or injury resulting from incorrect or improper installation practices. All electrical circuits should have a common AC protective earth or ground conductor routed from the AC service panel. The earth conductor should be bare, or green in color. A qualified electrician should perform all electrical installations. Advice and assistance is available free of charge by phone, fax or Email. |
| FITTINGS: |
(NOTE) Ozone is a very powerful oxidizer that will attack certain materials used in fittings, hoses and tubing. The absolute best material for the distribution of ozone is stainless steel or TEFLON (TFE). There are two primary areas of concern when selecting fittings for Chem-Free devices and systems. When the fitting is for atmospheric air supplied by a compressor, or air dryers such as the AD-10L pressure swing absorption process or a thermal process air dryer, virtually any type material may be used in the firings. The recommended material is brass or stainless steel; however, PVC, HDPE (High Density Polyethylene), KYNAR may also be used. We do not recommend nylon in any circumstances. When the fitting is passing ozone, material selection is much more limited. When the ozone is produced by a Chem-Free Ultraviolet system or device (Any Chem-Free model with a “U” at the beginning of the model number is an ultraviolet “UV” type ozone generator) the use of brass, PVC, HDPE, KYNAR, and naturally stainless steel is still permissible and even preferred. When the ozone system is a high voltage “Corona Discharge” or “CD” system (Any Chem-Free model with a “C” at the beginning is a CD type ozone generator) only KYNAR or stainless steel fittings are mandatory. NOTE: Under no circumstances should NYLON fittings or tubing be used to deliver ozone. NYLON will dissolve in rather sort order when exposed to ozone. |
| TUBING: |
Due to the high cost of TEFLON and stainless steel tubing, a cheaper alternative is used for distribution runs from the Chem-Free ozone generating system. Clear, internal braid reinforced Polyvinylchloride, (PVC) ¼” ID tubing is the preferred choice. This tubing will give many years of trouble free service carrying ozone to tanks and air handlers. After several years the tubing will become somewhat stiff and discolored a light brown, yet retain its integrity. Of course it is always permissible to use other types of appropriate tubing at the discretion of the boat owner or builder. All of the Woods Hole Oceanographic Institution Chem-Free WQA installations have stainless steel tubing runs from the equipment to the potable and black water holding tanks. Some yacht builders have also chosen stainless steel tubing for the distribution of ozone. Also available is stainless steel braid covered TEFLON which is the best of all, but is as expensive as it is tough and flexible. |
| SERVICE: | All Chem-Free ozone generators and the associated control/ozone delivery system are designed to require a minimum of maintenance. However, as with all electrical and/electronic devices, regular inspection of systems and components is highly recommended. Filters in particular should be inspected regularly and cleaned or replaced as necessary. The inside of all cabinets should be kept free of dust and debris. Cleaning is especially important in the case of high voltage type corona discharge type system. Dust will absorb moisture over time and can lead to a short circuit from the high voltage lead and/or terminal. Maintaining a good flow of cooling air is critically important for the CD cells in order to ensure proper ozone production and extend component service life. |
| Ultra Violet: | All Chem-Free UV type ozone generators have mirror polished 316 stainless steel reaction chambers in which the UV lamp is intended to remain for its entire operating life. NOTE: UV light emitted by the lamp is in the UV “C” band, or 184-nanometer wavelength, and is therefore very dangerous. Never operate the lamp when it is removed from the chamber as very short unshielded eye exposure (30 seconds or less) can result in permanent retinal damage, and sunburn. In order to maintain good ozone production, the recommended replacement period for all Chem-Free UV lamps is 12 to 18 months. All UV lamps deteriorate over time as the wavelength of the emitted light changes (lengthens) and ozone production is greatly reduced thereby. |
| “CD”: | There are two basic types of CD (Corona Discharge) chambers used in Chem-Free systems, a 1” and a 2”. Both may be disassembled for service and cleaning. Specific instructions for cleaning and/or replacement will be found in the accompanying manual. |
