CLEARANCESAll units require certain minimum clearances for proper opera-tion and service. Refer to Figure 4 for these clearances.WARNING: Do not permit overhanging structures or shrubs toobstruct condenser air discharge.Additional height may be required for snow clearance if winteroperation is expected.POWER AND CONTROL WIRINGInstall electrical wiring in accordance with the applicable na-tional, local and municipal codes. The unit should be groundedin accordance with these codes.POWER WIRINGCheck the voltage of the power supply against the data on theunit nameplate. Check the size of the power wire, the discon-nect switch and the fuses against the data in Table 3.NOTE: Copper conductors must be installed between the dis-connect switch and the unit.Refer to Figure 4 for the location of the power wire accessopening through the front of the unit. This opening will require afield-supplied conduit fitting.The field-supplied disconnect switch must be suitable for anoutdoor location. Although it should be installed near the unit,do NOT secure it to the unit cabinet.Refer to Figure 3 for typical field wiring.CONTROL WIRINGRefer to Figure 4 for the location of the control wire accessopening through the front of the unit.Route the necessary low voltage control wires from the TB1terminal block inside of the unit control box through this accessopening to the room thermostat and to the evaporator blowermotor controller. Wires #18 AWG (1.0mm 2 ) should be used.The room thermostat should be located on an inside wall ap-proximately 56" (1420mm) above the floor where it will not besubject to drafts, sun exposure or heat from electrical fixturesor appliances. Follow manufacturer's instructions enclosedwith thermostat for general installation procedure.Refer to Figure 3 for typical field wiring.COMPRESSORUnits are shipped with compressor mountings factory-adjustedand ready for operation.CAUTION: Do Not loosen compressor mounting bolts.COMPRESSOR CRANKCASE HEATERThe compressor is equipped with a crankcase heater to pre-vent refrigerant from mixing with crankcase oil during the“OFF” cycle. The heaters will be energized when the compres-sor is not running providing the unit disconnect switch isclosed.CAUTION: Do not attempt to start the compressor without atleast eight hours of crankcase heat or compressordamage will occur.If a unit has just been installed or the unit disconnect switch hasbeen open for a long period of time, move the system switch onthe room thermostat to the “OFF” position before closing theunit disconnect switch. Eight hours of crankcase heat are re-quired to drive the liquid refrigerant out of the compressor bef-ore the compressor can be started.035-15406-002-A-05044 Unitary Products Group5FT.MIN.FIG. 2 - TYPICAL RIGGING (090 MBH Unit Shown)5 Ft.
