If you are retrofitting for HFC refrigerants like R404A or R407C, the \"MTZ\" version with POE oil is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this compressor in a single-phase application?\u003c\/strong\u003e\u003cbr\u003eNo, the \u003cstrong\u003eMT40-3VI technical specs\u003c\/strong\u003e require a 200-230V 3-phase power supply. Attempting to run this on single-phase power with a kit will lead to motor failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I handle the freight shipping for this unit?\u003c\/strong\u003e\u003cbr\u003eDue to its weight and internal glass-to-metal seals, this 40,000+ BTU unit requires LTL truck transport to prevent transit damage.\u003c\/p\u003e\n\u003ch2 style=\"margin-top: 0in;\"\u003e\n\u003cstrong\u003e\u003cspan style=\"font-family: 'Segoe UI',sans-serif; color: #ff2a00;\"\u003eThis item is not eligible for free shipping and must be shipped via trucking.
