Any R-32 System with a full system refrigerant charge exceeding the M1 charge level of 4.050 lbs./1000 cu.ft., as specified by the safety standards, will require additional mitigation factors to be employed and/or room size restrictions. System charges not exceeding the M1 charge level will not require any room size restrictions or mitigation factors to be employed (see maximum charge - A2L limits tables this document) Use 4-Wire, 14AWG, Stranded, Non-Shielded Wire to Connect Outdoor to Indoor. Only Break L1 for proper condensate pump wiring (breaking L3 will result in a U4 Error Code). Mount outdoor units MINIMUM of 2" above anticipated snowfall. Always offer stand, disconnect, whip and pad. Wind Baffles recommended for all low temperature heating applications.
