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, 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.

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, optimum performance 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 another 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 kept 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

Braze The Refrigerant Lines

1. Remove caps or plugs. Use a deburing tool to debut the pipe ends. Clean both the 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 the liquid line filter drier’s directional flow arrow to confirm the correct direction of refrigeration flow (away from the outdoor unit and toward the 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.
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

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.
3. Remove nitrogen pressure and repair any leaks before continuing.

EVACUATION

Evacuate the Refrigerant Lines and Indoor Coil

NOTE: 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

Open the Service Valves

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

1. Remove Service Valve Cap (Fig. 10-1).
2. Fully insert the hex wrench into the stem and back out counterclockwise until the 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.
