9.0 INSTRUCTING THE OWNER
9.1 MAINTENANCE
. Dirt should not be allowed to accumulate on the outdoor coils or other parts in the air
circuit. Clean as often as necessary to keep the unit clean. Use a brush, vacuum
cleaner attachment, or other suitable means.
2. The outdoor fan motor is permanently lubricated and does not require periodic oiling.
3. If the coil needs to be cleaned, it should be washed with Calgon Coilclean (mix one
part Coilclean to seven parts water). Allow solution to remain on coil for 30 minutes
before rinsing with clean water. Solution should not be permitted to come in contact
with painted surfaces.
4. Refer to the furnace or air handler instructions for filter and blower motor maintenance.
5. The indoor coil and drain pan should be inspected and cleaned regularly to assure
proper drainage.
CAUTION
It is unlawful to knowingly vent, release or discharge refrigerant into the open air
during repair, service, maintenance or the final disposal of this unit. When the
system is functioning properly and the owner has been fully instructed, secure the
owner

struct the owner or the operator how to start, stop and adjust temperature setting. The
installer should instruct the owner on proper operation and maintenance of all other
system components.
8.2 CHARGING BY WEIGHT
For a new installation, evacuation of interconnecting tubing and indoor coil is
adequate; otherwise, evacuate the entire system. Note that charge value includes
charge required for 15 ft. of standard size interconnecting liquid line. Calculate actual
charge required with installed liquid line size and length using:
1/4
” O.D. = .3 oz./ft.
5/16 ” O.D. = .4 oz./ft
3/8
” O.D. = .6 oz./ft
1/2 ” O.D. = 1.2 oz./ft
With an accurate scale (+/-1 oz.) or volumetric charging device, adjust charge
difference between that shown on the unit data plate and that calculated for the new
system Installation. if the entire system has been evacuated, add the total calculated
charge.
8.3 FINAL LEAK TESTING
After the unit has been properly evacuated and charged, a halogen leak detector
should be used to detect leaks in the system. All piping within the condensing unit,
evaporator, and interconnecting tubing should be checked for leaks. If a leak is
detected, the refrigerant should be recovered before repairing the leak. The Clean Air
Act prohibits releasing refrigerant into the atmosphere.
