WARNING

• HAZARDOUS VOLTAGE! Failure to follow this warning could result in property damage, severe personal injury or death. Disconnect all electric power, including remote disconnects before service. Follow proper lockout /tagout procedures to ensure the power cannot be inadvertently energized.

• REFRIGERANT OIL! Any attempt to repair a central air conditioning product may result in property damage, severe personal injury, or death. These units use R-410a refrigerant which operates at 50% to 70% higher pressures than R-22. Use only R-410a approved service equipments. Refrigerant cylinders are painted a “Rose” color to indicate the type of refrigerant and may contain a “dip” tube to allow for charging of liquid refrigerant into the system. All R-410A systems use a POE oil (VG74 or equivalent) that readily absorbs moisture from the atmosphere. To limit this ‘hygroscopic“ action, the system should remain sealed whenever possible. If a system has been open to the atmosphere for more than 4 hours, the compressor oil must be replaced. Never break a vacuum with air and always change the driers when opening the system for component replacement.

• HIGH CURRENT LEAKAGE!
  Failure to follow this warning could result in property damage, severe personal injury, or death. Earth connection is essential before connecting electrical supply.

• SERVICE VALVES!
  Failure to follow this warning will result in abrupt release of system charge and may result in  personal injury and/or property damage. Extremecaution should be exercised when opening the Liquid Line Service valve. Turn valve stem counterclockwise only until the stem contacts the rolled edge. No torque is required.

• BRAZING REQUIRED!
  Failure to inspect lines or use proper service tools may result in equipment damage or personal injury. If using existing refrigerant lines make certain that all joints are brazed, not soldered.

CAUTION

Table 5-3 NOTE: 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, thecapacity 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.

Figure 5-2
The coil picture above in figure5-2 represents indoor unit, which includes J4AH and JMM models.

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

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 size of the refrigerant lines is correct. Refer to Section 5.2 and Table 5-2.
• Ensure that the refrigerant lines are free of leaks, acid, and oil.

NOTE
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, optimumperformance and the best overall system reliability.

REFRIGERANT LINE ROUTING

Precautions
NOTE

• 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 linesets from joists, rafters, walls, or other structural elements.

REFRIGERANT LINE BRAZING

Braze The Refrigerant Lines

1. Remove caps or plugs. Use a deburing tool to debur 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 (Fig. 7-4). Braze the refrigerant lines to the service valves. Check liquid line filter drier’s directional flow arrow to  confirm correct direction of refrigeration flow (awayfrom 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.
   • NOTE: Remove the wet rag before stopping the dry nitrogen purge.
