To avoid danger of suffocation, keep the plastic bag or thin film used as the packaging material away from young children.
Be sure not to allow foreign materials to enter the refrigerant piping. Seal the ends of refrigerant piping before storage.
For installation purposes, be sure to use the parts supplied by the manufacturer or other prescribed parts.
The use of non-prescribed parts can cause serious accidents such as the unit falling, water leakage, electric shock, or fire.
The rated power supply of this product is 208/230 VAC/60hz/1PH. Verify the voltage is within 187~253 range before turning the equipment on.
Supply power to the heat pump should be from a dedicated circuit that meets branch circuit ampacity requirements.
Use a special branch circuit breaker and receptacle matched to the power circuit capacity of the heat pump. Install in accordance with national, state, and local code.

CAUTION
It is highly recommended that you do not open or close the service valves when the outdoor temperature is below -5°F (-21°C), as this may cause refrigerant leakage.
Do not touch the fins of the coil. Touching the coil fins could result in damage to the fins or personal injury.
Ensure the power circuit capacity is adequate for all loads connected to the electrical service panel. Increase the conductor and panel capacity if the total electrical loads exceed the power source capacity.
Contact the power utility if the power provided is below equipment rating plate requirements.
Be sure to install a circuit breaker of the specified capacity.
Refer to local requirements regarding type and kind of circuit breaker, power wiring, and control cable.
Regulation of cables and circuit breaker differs from each locality. Be aware of these regulations prior to installation.
Do not use existing refrigerant lines.
Use refrigerant tubing that is clean and free of any contamination which may cause damage to the system, including sulfur, copper oxide, dust, metal chips, powder, oil, or water.
Avoid coupling lines whenever possible. Use a continuous length of copper tubing, as oxides formed during improper brazing techniques can damage the equipment.
Do not use copper pipes that have a collapsed, deformed, or discolored portion (especially on the interior surface). Otherwise, the expansion valve or capillary tube may become blocked with contaminants.
Improper line sizing will degrade performance. Peak pressure of R410A is much higher than R22. Use ACR copper tubing with adequate wall thickness.
Use a tubing bender to change piping direction. Make sure the radius of the bend is no less than 4”.
If the pipe is bent repeatedly at the same place, it will break.

Cutting

NOTE:
Be extra careful not to damage, dent, or deform the pipe while cutting. This will drastically reduce the operating efficiency of the unit.

Conventional Line Set Installation: Pipe Cutting / Pipe Flaring
Step 2: Deburring
Burrs will affect the air-tight seal of the refrigerant piping connection. They must be completely removed.

  1. Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
  2. Using a reamer or deburring tool, remove all inside and outside burrs from the cut section of the pipe.
  3. After cutting and deburing, never allow tubing to be exposed to the atmosphere. Tightly seal cut ends with PVC tape.

GE Appliances AUH2436ZGDA Split Type Heat Pump -
Deburring

All installations must have a field-supplied Bi-Flow filter drier installed within 8” of the liquid service valve.

Step 3: Flaring
Proper flaring is essential to achieve an airtight seal.

  1. Ensure there is enough insulation to protect the entire line set from end to end.
  2. Use the flare nuts from the accessories pouch, located in the indoor unit packaging. Fit the nut on the tubing to be flared.
  3. Remove the seal over the exposed end, and place the tube into the R-410A flaring tool.GE Appliances AUH2436ZGDA Split Type Heat Pump - Flaring 2
  4. Run the tube against the flaring tool pipe stop, and clamp the form on the tube.
  5. Rotate the handle of the die clockwise until the clutch releases, then remove the flared tubing from the form.GE Appliances AUH2436ZGDA Split Type Heat Pump - Flaring 3
  6. Examine the flare to make sure there are no imperfections on the lip of the flare, and that the back of the flare exactly fits the seat of the flare nut.

Conventional Line Set Installation: Pipe Connection
Flared Section

  • Apply refrigerant oil on the threads of the flare nut and the flare fitting.
  • With the tubing held so that the flare is seated straight onto the fitting, tighten the flare nut hand tight, pushing the pipe against the nut to make sure the flare remains fully seated.
  • Following the tightening specifications in the chart, use a torque wrench and back-up wrench to obtain the correct force on each flare nut.
  • Using permanent ink, record the line set length on the inside of the service door.
  • Repeat both Step 3 on the previous page, and this section, for the indoor unit connections.
  • Using core removal tools with full-flow shut off valves, remove both of the service valve cores at the outdoor unit, and attach a manifold gauge set to each service valve. Use a 3/8” heavy duty evacuation hose for the center port attachment.
  •  With the service valves closed, fill each tube with 500 PSI of dry nigrogen and check for leaks.
  • Evacuate the line set to at least 350 microns. From the final micron level obtained, shut off the vacuum pump. If the system rises no more than 150 microns within a minute and stops, the evacuation can be considered sufficient.
  • If the system rises more than 150 microns from the original vacuum, there is either a leak or moisture has not been removed. Locate and repair leak, or continue evacuation as needed.
  • When the evacuation is complete, replace the service valve cores through the core removal tool.
  •  Add additional refrigerant charge if needed before you open indoor service valves if indoor coil is so equipped.
  • Record the amount of refrigerant added in permanent ink at the line set length location entered earlier.
