If the installation requires draining the condensate water awayfrom the unit, install a field-supplied 2 -in. trap at the condensateconnection to ensure proper drainage. Condensate trap is availableas an accessory or is field-supplied. Make sure that the outlet of thetrap is at least 1 in. lower than the unit drain-pan condensateconnection to prevent the pan from overflowing. Connect a draintrough using a minimum of field-supplied 3/4-in. PVC or field-supplied 3/4-in. copper pipe at outlet end of the 2-in. trap. (See Fig.12) Do not undersize the tube. Pitch the drain trough downward ata slope of at least 1 in. every 10 ft. of horizontal run. Be sure tocheck the drain trough for leaks. Prime the trap at the beginning ofthe cooling season start-up.Step 7—Install Electrical ConnectionsThe unit cabinet must have an uninterrupted, unbrokenelectrical ground to minimize the possibility of personalinjury if an electrical fault should occur. This ground mayconsist of an electrical wire connected to the unit ground lugin the control compartment, or conduit approved for electricalground when installed in accordance with NEC, ANSI/NFPAAmerican National Standards Institute/National Fire Protec-tion Association (latest edition) (in Canada, Canadian Elec-trical Code CSA C22.1) and local electrical codes. Failure toadhere to this warning could result in serious injury or death.Failure to follow these precautions could result in damage tothe unit being installed:1. Make all electrical connections in accordance with NECANSI/NFPA (latest edition) and local electrical codesgoverning such wiring. In Canada, all electrical connec-tions must be in accordance with CSA standard C22.1Canadian Electrical Code Part 1 and applicable localcodes. Refer to unit wiring diagram.2. Use only copper conductor for connections betweenfield-supplied electrical disconnect switch and unit. DONOT USE ALUMINUM WIRE.3. Be sure that high-voltage power to unit is within operatingvoltage range indicated on unit rating plate. On 3-phaseunits, ensure phases are balanced within 2 percent. Consultlocal power company for correction of improper voltageand/or phase imbalance.4. Insulate low-voltage wires for highest voltage containedwithin conduit when low-voltage control wires are in sameconduit as high-voltage wires.5. Do not damage internal components when drilling throughany panel to mount electrical hardware, conduit, etc.HIGH-VOLTAGE CONNECTIONSThe unit must have a separate electrical service with a field-supplied, waterproof disconnect switch mounted at, or within sightfrom the unit. Refer to the unit rating plate, NEC and local codesFig. 9—Suggested RiggingUNIT MAXIMUM SHIPPING WEIGHT A BSize lb kg in. mm. in. mm.50XZ024 372 169 19.0 482.6 18.25 463.650XZ030NotYetAvailable“ “ “ “ “50XZ036 395 179 20.0 508 19.0 482.650XZ042NotYetAvailable“ “ “ “ “50XZ048 485 220 20.0 508 21.25 539.850XZ060 521 236 21.0 533.4 20.0 508.0C99075PLACE RIGGING BRACKET ASSEMBLY IN 4RIGGING HOLES AND INSTALL TIE DOWN STRAPAROUND PERIMETER OF UNIT AND THROUGHSPACE IN BRACKET ASSEMBLYINSTALL SAFETY STRAPS TORIGGING CLEVIS AT 4 RIGGING BRACKETSTIGHTEN STRAPPING SECURELYWITH TENSION BUCKLESEE DETAIL ADETAIL ASCALE 0.250914-137"(36"-54")“A”“B”8
