 MAINTENANCE & FAULT-FINDING 

8.1.

 

Cleaning and Handling 

Ideally when installing the unit handle with lint free gloves and degrease the unit to reduce the 
build-up of deposits. 

8.2.

 

Servicing 

There are in general no moving parts requiring routine maintenance. 

In the event of failure, prior to returning the unit to your authorised Gill distributor, it is 
recommended that: 

 

All cables and connectors are checked for continuity, bad contacts, corrosion etc. 

 

A bench test is carried out. 

 

Contact your supplier for advice if failure persists. 

 

8.2.1.

 

Wind Sensor (WindSonic) 

 

If there is any build-up of deposits on the unit, it should be gently 
cleaned with a cloth, moistened with soft detergent. Solvents 
should not be used, and care should be taken to avoid scratching 

any surfaces. The unit must be allowed to defrost naturally 
after being exposed to snow or icy conditions, do NOT 
attempt to

 remove ice or snow with a tool.  

There are no moving parts or user-serviceable parts requiring 
routine maintenance. 

Opening the unit or breaking the security seal will void the 
warranty and the calibration. 

 

8.2.2.

 

UV Radiation Shield (MetSpec) 

 

Ideally the user should try to keep the MetPak Temperature and 
Humidity housing radiation screens clean and free of biological 
growth but a simple wipe with some non- aggressive soft 
detergent cleaner will suffice. Solvents should not be used, and 
care should be taken to avoid scratching any surfaces. The unit 
must be allowed to defrost naturally after being exposed to snow 
or icy conditions, do NOT attempt to remove ice or snow with a 
tool.
