Periodic Maintenance
The Sherbourn 4Z-75 requires no periodic maintenance.
Cleaning the 4Z-75
• If necessary, the 4Z-75 should be cleaned gently with a soft rag.
• If something sticky gets on the front panel or case of the 4Z-75, it should be cleaned with a mild
cleaning solution applied to a soft rag, followed by wiping with a clean rag dampened with plain
water and drying with a soft dry rag or cloth.
Note: DO NOT spray water or cleaning solution directly onto the 4Z-75 or into the vents.
