The cover plate must be removed to gain access to the controls, and 
then sealed again to protect the controls against moisture and debris. 

Removal Procedure

1.  Locate the top six hex screws that hold down the sealed top 

cover. 

2.  Use a 2.5mm hex wrench to remove the six  screws.

3.  Gently lift cover off. It’s a very tight fit there, so you may need to 

use some gentle force. Yes, it is with you!  

4.     Keep the cover plate and screws in a safe and handy place, until 

you have finished adjusting the controls to your immense satis-
faction.
