SETUP AND OPERATION

4Mobile Box Fan User’s Manual©2018 Pinnacle Climate Technologies
Note: The fan unit you have purchased is built with heavy duty components, designed to give you many years of perfor-
mance. Like anything else that is mechanical, your fan unit will require a small amount of periodic maintenance to assure
maximum efficiency.
Our fans utilize motors that have totally sealed bearings. Periodically remove dust and grime that has accumulated on the
motor, fan blade, and guard. Pressure washing the unit will void the warranty. Performing this small amount of mainte-
nance will keep your fan unit running as efficiently as when it was brand new.
MAINTENANCE
Bi-annually
7000 hours
Clean motor, fan blade and guards.
• Disconnect power.
• Use an air hose to remove dust.
• Use a damp cloth to remove grime and grease.
• Pressure washing will void the warranty.
Grease the pillow block bearings.
• Use a grease gun and lithium-based / Shell #2 grease.
• Insert 4 grams into each grease zerk every 7000
hours of run time.
• Do not overgrease.
