1. Inspect the unit monthly to ensure that the glycol level is maintained to the full
level.
2. If the level is low replace with a Micro Matic Polar Flo glycol solution: mixed 2 ½
parts water to 1 part.
3. If there is evidence of ice build up in the unit, allow the ice to melt and replace
all the water/glycol solution with a fresh solution mixed per above instructions.
4. The glycol/water solution should be changed approximately every 18 months. In
regions of high humidity considerations should be given to replacing the solution
on an annual basis.
5. Check and clean the condenser fins every sixty (60) days.
6. Check that there is adequate air flow through the unit ensuring
enough space all around and that there are
no obstructions in front of the air flow vents.

the trunk line insulation.
8. At regular intervals, to be determined by
the owner, the unit should be checked for
electrical saftey.
