5. Maintenance
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.
UV Shield (RM Young Model 41003)
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.
HygroClip for Temperature, Humidity and Dewpoint (Rotronic
Model HC2-S3)
Periodically check the filter:
Corroded, discoloured or clogged dust filters should be replaced. Either replace the
polycarbonate dust filter screw-on cap (Rotronic part NSP-PCW-PE) or replace the
whole cartridge.
If you need to replace the dust filter cap, carefully unscrew it and withdraw carefully
avoiding contact with the Temperature and Humidity circuit board. When re-fitting
the filter cap, ensure the circuit board connections are not bent.
Consideration should be given to an annual calibration check of the HygroClip
sensor by the manufacturer.
If you are replacing the whole cartridge, unscrew the metal ferrule and return the
probe to Rotronic for calibration. Refer to the Rotronic Website for more details:

NOTE.
If you return the sensor to a HygroClip supplier for exchange, please
request that the return unit has the dewpoint feature enabled.
Barometer (on Hub PCB)
The Barometer device is maintenance-free, however, if required, clean the central
Hub box screw cap Gortex filter.
Returning the MetPak II
If the unit has to be returned, it should be carefully packed in the original packaging
and returned to your authorised Gill distributor, with a full description of the fault
condition. An RMA number should be obtained from Gill Instruments first if
returning directly to Gill Instruments.
