HOT SURFACE! DO NOT TOUCH TOP OF COMPRESSOR.COMPRESSOR AND DISCHARGE PIPES MAY BE EXTREMELY HOT.
IT MAY CAUSE MINOR TO SEVERE BURNING.
ALL R-410A SYSTEMS USE POE OIL. POE OIL EASILY ABSORBS MOISTURE FROM THE AIR. A SYSTEM WHICH HAS BEEN EXPOSED TO THE ATMOSPHERE FOR MORE THAN 4 HOURS REQUIRES THAT THE COMPRESSOR OIL BE REPLACED. NEVER BREAK A VACUUM WITH AIR AND ALWAYS CHANGE THE FILTER DRIER WHEN OPENING THE
SYSTEM FOR COMPONENT REPLACEMENT.

CAUTION! ! DRY NITROGEN SHOULD ALWAYS
BE SUPPLIED THROUGH THE TUBING WHILE IT IS BEING BRAZED, BECAUSE
THE TEMPERATURE REQUIRED IS HIGH ENOUGH TO CAUSE OXIDATION OF

11. SYSTEM CHARGE ADJUSTMENT
REFRIGERANT CHARGING MUST ONLY BE ATTEMPTED BY QUALIFIED CONTRACTORS. IMPROPER SYSTEM CHARGE CAN REDUCE SYSTEM CAPACITY AND MAY CAUSE EQUIPMENT DAMAGE.
WARNING !!
DO NOT LEAVE THE SYSTEM OPEN TO THE ATMOSPHERE. DO NOT ATTEMPT TO PUMP “TOTAL SYSTEM CHARGE” INTO OUTDOOR UNIT FOR MAINTENANCE, SERVICE, ETC. THIS MAY CAUSE
DAMAGE TO THE COMPRESSOR AND/OR OTHER COMPONENTS. THE OUTDOOR UNIT ONLY HAS ENOUGH VOLUME FOR THE “FACTORY CHARGE”, NOT FOR THE “TOTAL SYSTEM CHARGE”.
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.

WARNING! THIS TROUBLESHOOTING GUIDE IS INTENDED FOR USE BY QUALIFIED SERVICE PERSONNEL ONLY!
FAULT CONDITION POSSIBLE CAUSE CORRECTION
No cooling, outdoor unit not running, indoor fan running
Outdoor disconnect switch opened
- Close disconnect switch.
Fuse or breaker opened - Replace fuse, reset breaker
Faulty wiring - Repair or replace faulty wiring and
inspect connections
No cooling; indoor fan and outdoor unit will not run
Low-voltage control problem:
1. Thermostat 1. Repair loose connections or replace thermostat
2. Interconnecting, wiring, or connections
2. Repair or replace wiring or connections.
3. Transformer 3. Replace if defective.
No cooling; indoor and outdoor fan running, but compressor not running
Tripped compressor internal overload:
A. Low line voltage - Correct low voltage - Call power company - Repair loose connections
B. High head pressure:
- Dirty outdoor coil (condenser) - Clean outdoor coil - Outdoor coil fan not running all
the time - Check outdoor coil fan motor and
capacitor. - Outdoor coil air re-circulating - Correct recirculation problem. - Overcharge of refrigerant - Correct charge.
C. Low charge, motor not properly cooled
Correct charge; if due to leak, repair leak.
Indoor coil freezing
Restricted air�ow
- Change �lters. - Open all supply register dampers. - Clear return air blockage. - Clean fan blades. - Speed fan up to higher speed.
Low charge - Adjust unit charge—repair leak if
refrigerant has been lost. Metering device - Change or clean metering device. Restricted �lter drier - Change �lter drier.
