Winterization of Ozone Equipment

In areas of the world where the outside temperature drops considerably during winter months, problems can arise if steps are not taken prepare for such extreme conditions. Typically these problems will not become a threat until the temperature drops to about 20°F or below. Electronics can be destroyed, air dryer media desiccant can drop in effectiveness and water in pipes will tend to expand and split pipes.

The purpose of this post is to recommend some simple steps you can take to ensure your ozone generator will remain safe when down for the winter, allowing you to quickly resume use when the weather heats up.

Ozone Generator Shut Down & Storage

  • Begin by shutting down the equipment and letting any heated components cool down.
  • Disconnect main power.
  • Disconnect and air lines and electrical cords from your ozone generator.
  • Bring the generator indoors to a temperature controlled environment. This is recommended if the equipment is normally located outside in an open environment.
  • Wrap the ozone generator in a thick plastic bag to ensure that no moisture can get to your generator’s critical components while it is not operating. Some ozone generators come with a heat regenerative air dryer built in which requires the system to be energized continuously to prevent the media from over saturation.
  • Drain your vacuum break water. Most of our ozone generators utilize a water filled vacuum break as a secondary defense against water backflow when the pumps shut down. This technology requires this tubes to be filled with water during use.

Oxygen Concentrator Shut Down & Storage

  • Begin by shutting down the equipment and letting any heated components cool down.
  • Disconnect main power.
  • Disconnect and air lines and electrical cords from your oxygen concentrator.
  • Bring the concentrator indoors to a temperature controlled environment. This is recommended if the equipment is normally located outside in an open environment.
  • Wrap the ozone generator in a thick plastic bag to ensure that no moisture can get to your generator’s critical components while it is not operating. A couple large garbage bags doubled up will work fine as a cover. Some ozone generators come with heat regenerative air dryer built in that require the system to be heated at all times in order to the desiccant media from taking on to much moisture and over saturating.

Contact Tanks

  • Drain water from contact tanks.
  • Close off water lines that supply water to and from the equipment pad.

Vacuum Breaks

  • Drain water from the reservoirs.

Ozone Destructs & Water Traps

  • Disconnect power from the OCD11 or OCD21 destruct.
  • Drain water from the reservoir of the water trap.

Other Pool Equipment

Your pool technician should be able to answer any specific questions regarding the winterization of your pool related equipment.

The Importance of Maintenance

Performing regular maintenance will keep ClearWater Tech ozone systems operating at peak efficiency and will prevent most issues that may cause downtime. ClearWater Tech recommends all of our systems have preventative maintenance performed annually.

Signs that a system requires maintenance:

  • Reduced ozone output
  • Reduced airflow and vacuum readings
  • The system’s blue and white indicating media have changed color

A quick rundown of what maintenance entails*:

Ozone Generator:

  • Filter replacement
  • Check valve replacement
  • Fuse replacement
  • Reaction chamber inspection/cleaning
  • Reaction chamber o-ring replacement
EcoTex™ Ozone Laundry Equipment

EcoTex™ Ozone Laundry Equipment

The ozone generator will have one type of air preparation system, heat regenerative or an oxygen concentrator.

Air Preparation – Heat Regenerative:
(internal on /AD systems such as a CD10/AD, and or an external model such as an AD40)

  • Replacement of two medias

Air Preparation – Oxygen Concentrators:
(internal on SCL and Ae Apex systems, or external such as an OXS80)

  • Filter replacement
  • Pressure relief valve replacement
  • Compressor rebuild

Venturi Injector:

  • Check valve replacement

*The exact contents of each kit is determined by the model and revision of the system, the serial number is required to insure the proper parts are included in your kit.

 

Performing the maintenance is not difficult and should take less than an 1.5 hours the first time, and less time with experience. ClearWater Tech also offers an in-house repair service. Let ClearWater Tech do your maintenance for you!

Please contact the Service Department at ClearWater Tech at service@cwtozone.com or 1.800.262.0203 x23 or x27 for information on:

  • Part numbers and pricing of maintenance parts (Please have the serial numbers for the systems you wish to maintain).
  • Rebuilt reaction chambers to make performing maintenance easier.
  • In-house repairs.
  • Additional components to to aid in monitoring the systems and protecting against water back-flow.
  • Tool kits that include all the tools to perform maintenance on ClearWater Tech systems.
