This document is customer property and is to remain with this unit. These instructions do not cover all the different variations of systems nor does it provide for every possible contingency to be met in connection with installa- tion. All phases of this installation must comply with NATIONAL, STATE, AND LOCAL CODES. -
Page 4: Inspection
1.1 INSPECTION As soon as a unit is received, it should be inspected for possible damage during transit. If damage is evident, the extent of the damage should be noted on the carrier's delivery receipt. A separate request for inspection by the carrier's agent should be made in writing. - Page 5 AIR DISCHARGE: ALLOW 60” MINIMUM CLEARANCE.

Page 6: Unit Installation
3.0 UNIT INSTALLATION 3.1 LOCATION Before starting the installation, select and check the suitability of the location for both the indoor and outdoor unit. Observe all limitations and clearance requirements. The outdoor unit must have sufficient clearance for air entrance to the condenser coil, for air discharge and for service access. -
Page 7: Unit Location Considerations
The outdoor unit must be connected to the indoor coil using field supplied refrigerant grade copper tubing that is internally clean and dry. Units should be installed only with the tubing sizes for approved system combinations. The refrigerant charge shown in the nameplate is for standard size interconnecting liquid line lengths up to 15 feet. -
Page 8: Unit Mounting
2. Cold Climate Considerations (Heat Pump Only) Note: It is recommended that these precautions be taken for units being installed in areas where snow accumulation and prolonged below-freezing temperatures occur. • Units should be elevated 3-12 inches above the pad or rooftop, depending on local weather. -
Page 9: Factory-Preferred Tie-Down Method
3.7 FACTORY-PREFERRED TIE-DOWN METHOD Step 1: Prior to installing clear pad of debris. IMPORTANT Then cement pad must meet local codes and must be the proper thickness to accommodate fasteners. Step 2: Center and level unit onto pad. Step 3: Using field supplied L-shaped bracket to locate holes on concrete and drill pilot holes which is at least 1/4”... - Page 10 3. Care must also be taken to isolate the refrigerant lines to minimize noise transmis- sion from the equipment to the structure. 4. The suction line must be insulated. Tape and suspend the refrigerant lines as shown. DO NOT allow tube metal-to-metal contact. See Fig.7. 5.

Page 11: Precautions During Brazing Of Lines
3.9 PRECAUTIONS DURING BRAZING OF LINES All outdoor unit and evaporator coil connections are copper-to-copper and should be brazed with a phosphorous-copper alloy material such as Silfos-5 or equivalent. DO NOT use soft solder. The outdoor units have reusable service valves on both the liquid and suction connections. -
Page 12: Interconnecting Tubing
4. Braze the liquid line to the evaporator liquid connection. Nitrogen should be flowing through the evaporator coil. 5. Slide the plastic cap away from the suction connection at the indoor coil. Braze the suction line to the evaporator suction connection. Refer to the Table 1 for proper suction line sizing. -
Page 13: Maximum Length Of Lines
4.2 MAXIMUM LENGTH OF LINES T h e maximum length of interconnecting line is 100 feet . Always use the shortest length possible with a minimu m number of bends. N N OTE: Excessively long refrigerant lines cause loss of equipment capacity. 4.3 VERTICAL LIFT Keep the vertical lift to a minimum. -

Page 16: Checking Refrigerant Charge
7.0 CHECKING REFRIGERANT CHARGE Charge for all systems should be checked against the Charging Chart inside the access corner panel or Charging by weight. IMPORTANT:Do not operate the compressor without charge in system. Additio n of R - 410A will raise pressures (suction, liquid and discharge). 7.1 CHARGING BY LIQUID PRESSURE In order to properly charge the system, the following conditions must be met: 1) Outdoor temperature above 60°F. - Page 17 charging: weigh-In Method weigh-In Method can be used for the Initial installation, or anytime a system charge is being replaced. weigh-In Method can also be used when power is not available to the equipment site or operating conditions (indoor/Outdoor temperatures) are not In range to verify with the subcooling charging method.

Page 18: System Operation
8.0 SYSTEM OPERATION 1. Control logic description This frequency conversion system adopts the exactly same control logic as that of common fixed frequency unit. Start-up demand signal is sent by wired controller or indoor unit and when outdoor unit receives the signal, it will start required mode accord- ing to demand. -

● Defrosting enter The following 3 situations were determined to enter into defrosting: ①Outdoor coil temp. T3＜1℃, and satisfy a certain correspondence of T4 ambient temp. ②When operating time accumulates to a certain value. Because of ambient temp. T4 time settings are different, when T4<-5 ℃, cumulative time is 4h, when T4≥-5 ℃ and T4 ＜4 ℃, the cumulative time is 2h to determine. -
