Checking and Adding System Charge

The 4AC14 unit is factory-charged with enough HFC-410A

refrigerant to accommodate a 15-foot length of refrigerant

piping. Charge should be checked and adjusted using the

tables provided on the charging procedure sticker located

on the unit access panel. Detailed information is provided

in the 4AC14 Installation and Service Procedures manual.

Homeowner Information

Before attempting to perform any service or maintenance,

turn the electrical power to unit OFF at disconnect switch.

In order to ensure peak performance, your system must

be properly maintained. Clogged filters and blocked air-

flow prevent your unit from operating at its most efficient

level. The system should be inspected and serviced be-

fore each cooling and heating season by a licensed pro-

fessional HVAC service technician (or equivalent).

The following maintenance may be performed by the

homeowner.

• Contact a licensed professional HVAC technician to

schedule inspection and maintenance appointments for

your equipment before each heating and cooling sea-

son.

• Check the indoor unit filter each month and replace the

filter, if necessary.

• Have your dealer show you where your indoor unit filter

is located. It will be either at the indoor unit (installed

internal or external to the cabinet) or behind a return air

grille in the wall or ceiling. Check the filter monthly and

clean or replace it as needed. Disposable filters should

be replaced with a filter of the same type and size.

• Check the indoor unit drain line for obstructions month-

ly. The indoor coil is equipped with a drain pan to collect

condensate formed as your system removes humidity

from the inside air. Have your dealer show you the loca-

tion of the drain line and how to check for obstructions.

(This would also apply to an auxiliary drain, if installed.)

• Check the area around the outdoor unit monthly and

remove any obstructions that may restrict airflow to the

outdoor unit. This would include grass clippings, leaves,

or papers that may have settled around the unit.

• Trim shrubbery away from the unit and periodically

check for debris which collects around the unit.

• During the winter months, keep the snow level below

the louvered panels.

NOTE - The filter and all access panels must be in place

any time the unit is in operation. If you are unsure about

the filter required for your system, call your dealer for as-

sistance.
