Lesson 10.2 – Maintaining Safe Operations

Lesson 10.2 – Maintaining Safe Operations

To ensure proper operation the cleaning system, a maintenance schedule should be followed. The following table describes the maintenance intervals for various tasks necessary for optimal, trouble-free operation.

If increased wear of individual components is uncovered during inspections, the operator must increase the required maintenance interval on the basis of the actual signs of wear.

Some tasks, such as clearing debris, is highly dependent on climate and environmental conditions.

If a part is found to be defective, using a replacement that is not certified by RST-CleanTech may void the warranty and can result in damage, malfunctions or total failure of the system. Spare parts should be ordered directly from RTS-CleanTech.

When checking for leaks and sprinkler operation, you’ll need to activate the water supply for the system. Set the automatic valve(s) to “Manual”, and let the system be pressurized. When done, set the valves(s) back to automatic.


Interval Required Maintenance


Visual inspection of solar array and surrounding area for leaks, damage, accumulated debris, etc.  If some panels appear dirty compared to others, there may be an issue.  Also inspect area around garden faucet and control box for signs of water leakage.  See the troubleshooting section if a problem is found.

Every 12 months

If it will stay below freezing regularly in your area in the winter months, you’ll need to shut the water supply off and drain all the piping in the system. First, shut off the water supply at the garden faucet. Then open all valves manually and remove the attachment fitting at the garden faucet. Let all the water drain out, and then re-attach the fitting
To prepare for the dry, warm weather season, close all valves manually. Then turn on the water supply at the garden faucet. Then follow this procedure to activate the system.
Replace filter.   Not replacing the filter will keep the system from removing limescale from your water.    In such case, your panels may be damaged.   Yearly replacement of the filter is mandatory for proper functioning and protecting the panel warranty.
Replace the two AA batteries. The batteries can last up to three years with this system with normal operation. However, we recommend replacing them annually to ensure proper functioning.


Replacing the filter

The photo sequence below shows how the filter is replaced (must be done annually).

  1. Unhook the filter removal tool from inside the control box (photo 1)
  2. Loosen the filter housing (photo 2)
  3. Once loosened, unscrew and remove the housing by hand (photo 3)
  4. Remove the filter (red insert) as shown in photo 4.
  5. Clean out any dirt accumulated inside the casing and replace the filter
  6. Tighten the housing back on by hand
  7. Tighten the filter with the tool.
