NOTES:
■ Handle the HEPA air filter gently to prevent damage to the
fabric media.
■ The HEPA air filter should not be cleaned. It should be
replaced when it becomes restrictive.
Fresh Air Return
If your system includes the optional fresh air return, it will have an
outside air intake. Check and clean the hood screen on the
outside air intake seasonally. The intake hood screen must
remain clear of any debris that could restrict airflow into the
dehumidifier.
UVC Germicidal Light
WGDH160UH and WGDV160UH models are equipped with UVC
germicidal ultraviolet lights. The bulb for the germicidal ultraviolet
light is rated for at least 9,000 hours (1 year) when used in
accordance with the whole house dehumidifier installation
instructions. The bulb may last longer in some situations, but
annual bulb replacement is recommended since UVC ouput is
typically reduced by about 25 percent at 9,000 hours and drops
off more rapidly afterward.
To replace the UVC light bulb
1. Disconnect power.
2. Remove the filter access panel.
3. Remove the electrical access panel.
4. Remove the internal component access panel.
5. Remove the connector from the UVC light and sleeve.
