G/VSZ130[18-60]1A*
* Up to 24' in equivalent line length
(1) Wire size should be determined in accordance with National Electrical Codes; extensive wire runs will require larger wire sizes.
(2) Maximum Overcurrent Protection Device: MUST use Time Delay Fuse or HACR type Circuit Breaker of the same size as noted.
NOTES:
• Always check the S & R plate for electrical data on the unit being installed.
• Installer will need to supply 7/8" to 1-1/8" adapters for suction line connections (4 & 5 ton units).
• Installer will need to supply 3/4" to 7/8" adapters for suction line connections (3 ton unit).
• Unit is charged with refrigerant for 15' of 3/8" liquid line. System charge must be adjusted per Installation Instructions Final Charge
Procedure.
• Installation of these units requires the specified TXV Kit to be installed on the indoor coil. THE SPECIFIED TXV IS DETERMINED BY THE
OUTDOOR UNIT, NOT THE INDOOR COIL.
