YouTube Video: Climate Wizard CW3 and CW6 Core Cleaning Procedure
MAINTENANCE SCHEDULE Maintenance of an indirect evaporative cooler is essential in maintaining proper performance and reliability. All maintenance must be done by competent, qualified, licensed technicians, in accordance with National and/or Local Regulations. The frequency of service is largely dependent on the conditions under which the cooler is operated. External factors, such as air and water quality, can affect the serviceable life of the cooler and its components. Similarly, the amount and type of use can also have a significant impact.
CW3 / CW6 Microcore cleaning method using wire brush and water hose
Requirements
- IMPORTANT that Cores are completely dry before commencing this method of microcore cleaning.
- Always use correct PPE (goggles and gloves)
- Wire brush
- Large flat head Screwdriver
- Water hose connected to a potable water supply -
Seeley International only recommends that potable water is used to clean the tanks and cores of Climate Wizards.
Do not use cleaning solvents or chemicals as they may deteriorate the plastics and glues used in manufacturing, reduce performance of the appliance and contaminate the conditioned air.
Procedure
- Wire brush face of core until all calcification has been removed (vast majority).
2. Using a wire brush, firmly stoke the pleats of the microcore from across the whole face of the core (first downwards, then upwards) to break up any calcification on the inside of the microcore folds (This process can be performed 6-10 times). This will ensure that when water is applied in the later steps, the volume of water will be able to wash away the debris.
3. If required a flat head screwdriver can be used to clean any calcification off the front face of the microcore where the exhaust manifold is mounted.
4. Once cleaning with wire brush is complete a few gentle taps (6-10 times) on the ground of the microcore are required to release the majority of the calcium flakes form the microcore. (Please ensure that the core is dropped from a max height of 100mm to ensure no damages is caused to plastic manifold).
5. Results from dry cleaning.
6. Using a standard garden hose (with a nozzle and on the jet stream setting) apply the nose of the hose to the face of the core so that they are touching and slowly move the hose up and down the face of the core to flush any of the debris still captured within the pleats of the core so that it flushes away. (A wire brush can be used to help flick through the pleats as your watering the microcore in photos).

7. Flip the core and then run the hose up and down the air inlets.
8. Inspect for residual debris and repeat the flushing process if required.
Note:
Final examination will show that the face of the core will being dramatically improved from its initial state and that most if not all the calcium will be removed from the dry side of the cores. The wet side will still have residual calcium, but this is non-problematic. As long as the calcium on the face of the core is removed and in the dry sides removed then this should be sufficient.
9. Drying the Microcore
While the microcores are removed, use the opportunity to thoroughly clean the water tank. (Silt and debris in the tank will get coated onto the core blocking them more quickly.)
When washing the dust and debris from the cores, residual water may accumulate in the dry channel. To remedy this, reinstall the cores into the CW3 unit (keeping the filter pad frames off) and activate the unit in SERVICE OPERATING SCREEN. Ensure the pumps are off, and the supply fan is OFF while the exhaust fan is ON, running at speed 6. This process should last approximately 15 minutes to effectively dry out the channels and eliminate any remaining debris.
During this drying period, it's imperative to inspect and either wash or replace the filters as necessary.
The Service operating screen can be entered using a MagIQtouch controller
