USER INFORMATION IMPORTANT SAFETY INFORMATION Safety markings are used frequently throughout this manual to designate a degree or level of seriousness and should not be ignored. WARNING indicates a potentially hazardous situation that if not avoided, could result in personal injury or death. CAUTION indicates a potentially hazardous situation that if not avoided, may result in minor or moderate injury or property damage.
USER INFORMATION At the beginning of the defrost cycle, both the outdoor condenser fan and compressor will turn off. After approximately 30 seconds, the compressor will turn on and begin to heat the outdoor coil causing the ice and snow to melt. NOTE: While the ice and snow is melting, some steam may rise from the outdoor unit as the warm coil causes the melting frost to evaporate. When defrost is completed, the outdoor fan motor will start, and the compressor will turn off again.
INSTALLER INFORMATION IMPORTANT SAFETY INFORMATION Please read all instructions before servicing this equipment. Pay attention to all safety warnings and any other special notes highlighted in the manual. Safety markings are used frequently throughout this manual to designate a degree or level of seriousness and should not be ignored. WARNING indicates a potentially hazardous situation that if not avoided, could result in personal injury or death.
Before you install this unit The cooling load of the area to be conditioned must be calculated and a system of the proper capacity selected. It is recommended that the area to be conditioned be completely insulated and vapor sealed. Check the electrical supply and verify the power supply is adequate for unit operation. If there is any question concerning the power supply, contact the local power company.
Air Filter Requirements WARNING: Never operate the unit without a filter in place. Dust and lint could accumulate on internal parts, resulting in loss of efficiency, equipment damage and possible fire. Replace disposable filters with the same type and size. • Air filter(s) are not supplied and must be installed in the return air system by the installer.Only three phase units are equipped with an internal filter rack assembly. • All return air must pass through the filters before entering the unit.
slab height must be a minimum of 2” (5cm) above grade and with adequate drainage. • Units require horizontal roof curb and return air kit for horizontal installations. • Ductwork should be attached directly to flanges on panels supplied in horizontal duct conversion kits. Rooftop Rooftop installations must be located according to local building codes or ordinances and these requirements: • The roof must be capable of handling the weight of the unit. For unit weights, see Table 4 (page 15).
Condensate Drain Figure 6. Condensate Drain Location ELECTRICAL WIRING WARNING: To avoid risk of electrical shock, personal injury, or death, disconnect all electrical power to the unit before performing any maintenance or service. The unit may have more than one electrical supply. Label all wires prior to disconnection when servicing the unit.
Unbalanced 3-Phase Supply Voltage Voltage unbalance occurs when the voltages of all phases of a 3-phase power supply are no longer equal. This unbalance reduces motor efficiency and performance. Some underlying causes of voltage unbalance may include: Lack of symmetry in transmission lines, large single-phase loads, and unbalanced or overloaded transformers. A motor should never be operated when a phase imbalance in supply is greater than 2%.
Defrost Control Board Operational Informaton • Terminals R - C must have 24V present between them for the time delay and defrost sequences to be operational. • Jumpering the T2 - DFT test pins will communicate to the board that the defrost thermostat is closed (if the compressor is running). The defrost T-stat tells the board whether a defrost cycle needs to be started or terminated.

Thermostat Wire Gauge START UP & ADJUSTMENTS Pre-Start Check List Verify the unit is level and allows condensate to drain. Verify the outdoor coil and top of the unit are free from obstructions and debris, and all equipment access/ control panels are in place. Verify that the duct work is sealed to prevent air leakage.
NOTES: • The unit must be charged while both first and second stages are operating. • To achieve rated capacity and efficiency the compressor must be exposed to refrigerant for at least 24 hours prior to running and then must be run for a minimum of 12 hours. • The refrigerant charging charts (Figures 12 - 14, pages 20 & 21) are applicable to listed assemblies of equipment and at listed airflows for the indoor coil. Assemblies of indoor coils and outdoor units not listed are not recommended.
