Table 1
The unit’s weight value is on the cardboard box.
When mounting the outdoor unit on a roof, be sure the roof will support the unit’s weight. Properly selected isolation is recommended to prevent sound or vibration transmission to the building structure.

2.2 Location restrictions
Ensure the top discharge area is unrestricted for at least 60 inches above the unit.
Do not locate outdoor unit near bedrooms since normal operational sounds may be objectionable.
Position unit to allow adequate space for unobstructed airflow, wiring, refrigerant lines, and serviceability.
Maintain a distance of 24 inches between units.
24 inches clearance must be provided in front of the control box (access panels) and any other side requiring service.
Position unit where water, snow or ice from roof or overhang cannot fall directly on unit.
Position the outdoor unit a minimum of 12’’ from any wall or surrounding shrubbery to ensure adequate airflow.
See Figure 2 and Figure 3.
Cold climate considerations (heat pump only)
Precautions must 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. This additional height will allow drainage of snow and ice melted during defrost cycle prior to its refreezing. Ensure that drain holes in unit base  pan are not obstructed, preventing drainage of defrost water (Figure 4).
If possible, avoid locations that are likely to accumulate snow drifts.
If not possible, a snow drift barrier should be installed around the unit to prevent a build-up of snow on the sides of the unit.

Unit preparation

3.1 Pre-installation
STEP 1 – Check for damage and report promptly to the carrier any damage found to the unit (Figure 5).
STEP 2 – Instruments must be designed to install/serve R410A equipmens.

• Gauge sets, hoses, refrigerant containers and recovery system must be designed to handle the POE type oils.
• Manifold sets should be 800 PSIG high side and 250 PSIG low side.
• All hoses must have a 700 PSIG service pressure rating.
• Leak detectors should be disigned to detect R410A.
• Recovery equipments (including refrigerant recovery containers) must be specifically designed to handle R410A.
• Do not use an R22 TXV.
  

Setting up the unit

4.1 Pad installation
When installing the unit on a support pad, such as a concrete slab, consider the following:

• The pad must be at least 1-2” larger than the unit on all sides.
• The pad must be separate from any structure.

Table 5 Suction line length/size VS capacity multiplier
Using suction line larger than shown in chart will result in poor oil return and is not recommended.
For example: the system capacity published in AHRI is 17800 Btu/h. This data is based on the AHRI test condition and 25 feet line set with standard suction tube size (3/4″ tube). If you need to add the line set more than 25 feet or use the optional suction tube size, you need to recalculate the capacity with the coefficient in the table. For 50 feet line and 5/8″ suction tube, the capacity will be 17800*0.97=17266 Btu/h.
Determine required line length and lift. You will need this later in Section 14.
Total Line Length = __ Feet.
Total Vertical Change(Lift) = __ Feet.

5.4 Refrigerant line insulation
The suction line must always be insulated. DO NOT allow the Liquid Line and Suction Line to come in direct (metal to metal) contact.

5.5 Reuse existing refrigerant lines

CAUTION:
If using existing refrigerant lines make certain that all joints are brazed, not soldered.
For retrofit applications, where the existing refrigerant lines will be used, the following precautions should be taken:
Ensure that the refrigerant lines are the correct size. Refer to Section
5.1 listed and Table 3.
Ensure that the refrigerant lines are free of leaks, acid, and oil.
The manufacturer recommends installing only approved matched indoor and outdoor systems. All of the manufacturer’s split systems are AHRI certified. Some of the benefits of installing approved matched indoor and outdoor split systems are maximum efficiency, optimum performance and the best overall system reliability.

Refrigerant line routing

6.1 Precautions
Take precautions to prevent noise within the building structure due to vibration transmission from the refrigerant lines. For example:

• When the refrigerant lines have to be fastened to floor joists or other framing in a structure, use isolation type hangers.
• Isolation hangers should also be used when refrigerant lines are run in stud spaces or enclosed ceilings.
• Where the refrigerant lines run through a wall or sill, they should be insulated and isolated.
• Isolate the lines from all ductwork.
• Minimize the number of 90º turns.
• Use PVC piping as a conduit for all underground installations as shown in Figure 15. Buried lines should be keep as short as possible.
• The lines should not obstruct service access to the coil, air handling system or filter.
• Care must also be taken to isolate the refrigerant lines to minimize noise transmission from the equipment to the structure.

Comply with National, State, and Local Codes when isolating line sets from joists, rafters, walls or other structural elements.

Refrigerant line brazing

7.1 Braze the refrigerant lines

1. Remove caps or plugs. Use a deburring tool to deburr the pipe ends.
   Clean both internal and external surfaces of the tubing using an emery cloth.

2. Remove the pressure tap cap from both service valves.

3. Purge the refrigerant lines and indoor coil with dry nitrogen.

4. Wrap a wet rag around the valve body to avoid heat damage and continue the dry nitrogen purge (Figure 19).
   Braze the refrigerant lines to the service valves.
   Check liquid line filter drier’s directional flow arrow to confirm correct direction of refrigeration flow (away from outdoor unit and toward evaporator coil) as illustrated. Brazing the filter drier to the Liquid Line.
   Continue the dry nitrogen purge. Do not remove the wet rag until all brazing is completed.
   Remove the wet rag before stopping the dry nitrogen purge.

5. Replace the pressure tap caps after the service valves have cooled.
   Note: Do not over tighten (between 40 and 60 inch-lbs. maximum).

Refrigerant line leak check

8.1 Check for leaks

1. Pressurize the refrigerant lines and evaporator coil to 150 PSIG using dry nitrogen.
2. Check for leaks by using a soapy solution or bubbles at each brazed location.

Remove nitrogen pressure and repair any leaks before continuing.

Evacuation

9.1 Evacuate the refrigerant lines and indoor coil
Do not open the service valves until the refrigerant lines and indoor coil leak check and evacuation are complete.

1. Evacuate until the micron gauge reads no higher than 350 microns, then close off the valve to the vacuum pump.

2. Observe the micron gauge. Evacuation is complete if the micron gauge does not rise above 500 microns in one (1) minute.
   Once evacuation is complete blank off the vacuum pump and micron gauge, and close the valves on the manifold gauge set.

Service valves

10.1 Open the service valves
WARNING:
Extreme caution should be exercised when opening the Liquid Line Service Valve. Turn counterclock wise until the valve stem just touches the rolled edge. No torque is required. Failure to follow this warning will result in abrupt release  of system charge and may result in personal injury and /or property damage. Leak check and evacuation must be completed before opening the service valves.

1. Remove service valve cap (Figure 25).
2. Fully insert hex wrench into the stem and back out counterclockwise until valve stem just touches the rolled edge.
3. Replace the valve stem cap to prevent leaks. Tighten finger tight plus an additional 1/6 turn.

System charge adjustment

14.1 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 liquid line pressure charging method.

The factory charge in the outdoor unit is sufficient for 15 feet of standard size interconnecting liquid line.
New Installations — Calculating additional charge for lineset greater than 15 feet.

1. Total Line Length (ft)= (a)
2. Standard Line set (ft)= 15 (b)(a) minus (b)
3. Refrigerant Multiplier = (c)
4.  Refrigerant Adder (cd) = (d)= (e)
5. *If lineset is less than 15 feet, (e) = 0

Sealed-System Repairs — Calculating total system charge.

1. Total Line Length (ft)=__ (a)
2. Standard Line set (ft)= __15 (b)
3. (a) minus (b)= (c)=__ (d)
4. Refrigerant Multiplier= __(e*)
5. Refrigerant Adder (c*d)= __(f)
6. Factory Charge (nameplate)
7. Total System Charge (e+f)

*If line set is less than 15 feet, (e) = 0

The only mode approved for validating system charge is while in Cooling Mode. Outdoor Temperature must be between 55°F and 115°F with Indoor Temperature kept between 70°F and 80°F.
14.2 Liquid line pressure charging and refrigerant adjustment in cooling (above 55°F outdoor temp.)
• For 5 TON AC unit,the Outdoor Temperature must be between 65°F and 105°F

1. Check the outdoor ambient temperatures.
   Liquid line pressure (in cooling mode) is the only recommended method of charging above 55ºF outdoor ambient temperatures.
   For outdoor ambient temperatures below 55ºF , use weigh-in charge method.
   Note: It is important to return in the spring or summer to accurately charge the system in the cooling mode when outdoor ambient temperature is above 55ºF. For best results the indoor temperature should be kept between 70ºF to 80ºF. Note: The temperature tolerance for actual approach is ± 3ºF.

2. Ensure Sections 7, 8, 9, 10,11,12 and 13 have been completed.

3. Stabilize the system by operating for a minimum of 20 minutes.
   At startup, or whenever charge is removed or added, the system must be operated for a minimum of 20 minutes to stabilize before accurate measurements can be made. Note:The pressure tolerance for actual approach is ± 5psig

4. Calculate liquid line pressure (According to Refrigerant Charging Chart)
   • Measured Suction Line Pressure = ____PSIG
   • Outdoor Ambient Temperature = ___ ºF
   • Calculate Liquid Line Pressure = ____PSIG

Add refrigerant if the design liquid line pressure is lower than the chart value.

• Connect gages to refrigerant bottle and unit as illustrated (Figure 40).
• Purge all hoses.
• Open bottle.
• Stop adding refrigerant when liquid line pressure matches the
• Refrigerant Charging Chart.

Recover refrigerant if the design liquid line pressure is lower than the chart value.

Stabilize the system.

• Wait 20 minutes for the system condition to stabilize between adjustments.
• When the liquid line pressure match the chart, the system is properly charged.
• Remove gages.
• Replace service port caps to prevent leaks. Tighten finger tight plus an additional 1/6 turn.

Record system Information for reference (Table 8).
Record system pressures and temperatures after charging is complete.

System operation and troubleshooting

15.1 Compressor crankcase heater (CCH) (Heat pump only)
The crankcase heating start must meet two conditions:
A. Outdoor temperature＜41°F
B. At power up or if the compressor has been off for more than 3 hours
The crankcase heating stop must meet the following condition: Outdoor temperature＞44.6°F or compressor starts.
15.2 Reversing valve (Heat pump only)
Reversing valve energizes at the heating conditions, and cuts off at the cooling condition.
15.3 Protection function (Heat pump only)
T3 = Outdoor Coil Temperature
T3＞143.6°F, compressor stops working
T3＜125.6°F, compressor restarts working
T4 = Out Ambient Temperature
T4 < 5°F, compressor stops working
T4 > 10.4°F, compressor restarts working
When T4< 5°F, the outdoor unit would provide a signal to drive up the heater installed in the indoor unit.

• Discharge temperature protection
  Discharge temperature > 275°F, compressor stops working.
  Discharge temperature < 194°F, compressor restarts working.

• High pressure protection
  High pressure > 638 PSIG, compressor and outdoor fan motor stop working.
  High pressure < 464 PSIG, compressor and outdoor fan motor restart working (3 minutes delay necessary).

• Low pressure protection
  Low pressure < 21 PSIG, compressor and outdoor fan motor stop working.
  Low pressure > 44 PSIG, compressor and outdoor fan motor restart working (3 minutes delay necessary).

In stand-by status, the compressor will not start in low pressure protection. Within 30 minutes, if 4 protection cycles occur. The system will be locked. It will be restore after power cycle.
15.4 Protection function (Air conditioner only)
High pressure protection
High pressure > 638 PSIG, compressor and outdoor fan motor stop working.
High pressure < 464 PSIG, compressor and outdoor fan motor restart working (3 minutes delay necessary).

15.5 Defrost mode (Heat pump only)
Manual defrost mode
When the switch SW3-1 is set to “ON”, the system turns to the defrost mode. The defrost mode exits by the logic of shut-down conditions of defrost mode.
