Daikin RoofPak RAH - IM 987: Monthly Maintenance

Preparation

Supply (and Return) fans

Move the motor base to check and lubricate slides and leadscrews.
Remove the drive belts, tag them with the fan name and unit serial number, and store them in a conditioned space out of direct sunlight.
Turn supply and return fan Manual Motor Protectors (MMPs) to the OFF position.
Once every month, rotate the fan and motor shafts. Mark the shaft positions first to make sure they stop in a different position.
Depending on local climatic conditions, condensate may collect on components inside the units. To prevent surface rust and discoloration, spray all bare metal parts with a rust preventive compound. Pay close attention to fan shafts, sheaves, bearings, and bearing supports.

Cabinet Sections

Once a month, open a door on each section and verify that no moisture or debris is accumulating in the unit.
