THERE IS A RISK OF ELECTRIC SHOCK. IT CAN CAUSE INJURY OR DEATH:
DISCONNECT ALL REMOTE ELECTRIC POWER SUPPLIES BEFORE SERVICING!
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.

NEVER ATTEMPT TO REPAIR ANY BRAZED
CONNECTIONS WHILE THE SYSTEM IS
UNDER PRESSURE. PERSONAL INJURY
COULD RESULT.
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
THE COPPER UNLESS AN INERT ATMO-
SPHERE IS PROVIDED. THE FLOW OF DRY
NITROGEN SHOULD CONTINUE UNTIL
THE JOINT HAS COOLED. ALWAYS USE
A PRESSURE REGULATOR AND SAFE-
TY VALVE TO INSURE THAT ONLY LOW
PRESSURE DRY NITROGEN IS INTRO-
DUCED INTO THE TUBING. ONLY A SMALL
FLOW IS NECESSARY TO DISPLACE AIR
AND PREVENT OXIDATION.

11. SYSTEM CHARGE ADJUSTMENT
REFRIGERANT CHARGING MUST ONLY BE ATTEMPTED BY QUALIFIED CONTRACTORS. IMPROP-
ER 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 !!
Allairconditioningunitscomepre-chargedwithenoughrefrigerant(R410A)foranappropriatelymatched
indoorevaporatorcoil.Foreldinstalledlineset,acorrectionof0.6OzofR410Aperfootoflinesetisrequired

Thesystemchargeshallbeadjustedaccordingtosection11.2or11.3dependingontheapplication.
ToobtainanefcientsystemmatchingAHRIperformance,unitswitheitherthermostaticexpansion
