In this article we provide instructions for troubleshooting overheating issues on ValoClimb DustProtect.

Note: These instructions are only applicable for the DustProtect model, if you have ValoClimb 6K or ValoClimb 9K, that is experiencing overheating issues, please contact support@valomotion.com. 

Cleaning the air intake filter

The most common cause for overheating in ValoClimb DustProtect unit is a clogged air intake filter. This filter is easy to clean, and should be regularly cleaned at least once per week to prevent any temperature issues. Note that the filter will eventually need replacing. Depending on the amount of dust and the frequency of cleaning, filters will work between 1-3 years. Replacement filters are available from Valo Motion.

The air filter is located on the back side of the main unit (see image below).

The filter is best cleaned with a vacuum cleaner. Please use a ladder to access the filter and check that there is no more dust or other visible dirt on the filter after you have performed the cleaning procedure.

Checking intake fan functionality

The ValoClimb system is cooled by two intake fans, located on the inside of the main unit case. In some cases these fans might not be functioning properly and this is easy to determine by performing a visual check.

Making sure both fans are functional

1. Make sure the unit is turned ON while you perform this check
2. Get a ladder to access the main unit
3. Open main unit lid by unlocking the black latches on both sides of the case
4. Carefully lift the lid open, you can leave it in it's fully open position while you perform the check
5. The fans (2 fans) are located on the back of the case, and both fans should always be spinning when the unit is turned on

Checking fan controller functionality

The fans are regulated by a temperature sensor on the inside of the case, to make sure that the fan controller is working, the temperature sensor needs to be tested.

1. Leave the main unit case open for at least 5 minutes to make sure the system reaches ambient temperature
2. Locate the temperature sensors, on front side of the case (see image)
3. Take the end of both sensors and press them between your fingertips for at least 20 seconds (see image)
4. This will heat up the temperature sensor and you should hear the fans become louder

If the fans become louder when warming up the temperature sensors, this means the fan controller is working as it should

What to do if filter is cleaned and fans are working?
