MINIMUM CLEARANCES

(Appearance may vary)
This picture is for reference only. Your product may look different. Read your manual before installation. Explain the operation of the unit to the user according to this manual.

Step 1 – Preparation

Select the Outdoor location:

• Choose a level place solid enough to bear the weight and vibration of the OD unit and where the operation noise will not be amplified.
• Choose a location where the hot air discharge and/or noise will not create a nuisance for neighbors.
• Ensure there is sufficient space to maneuver the OD unit into place.
• Ensure there is sufficient space and no obstructions for the air inlet and outlet.
• Install the unit’s power/communication wiring at least 10 feet away from television and radio sets to prevent interference.
• Ensure any moisture sensitive items are kept away from the condensate drain path of the OD unit.
  NOTES:
• OD unit cannot hang from a ceiling or be stacked.
• Ensure that accumulated snow and debris will not block the air inlet or the coil if installing the outdoor unit with a fence or guard rail around it.
• Ensure ventilation in case of refrigerant leakage.
  R- 410A is a safe, nontoxic, and nonflammable refrigerant.
• Avoid installing the OD unit where corrosive gases, such as sulfur oxides, ammonia, and sulfurous gas are produced. Consult with an installation specialist about using a corrosion-proof or anti-rust additive to protect the unit coils.

Step 2 – Installation of the Indoor Unit 

Proper Installation for Drainage

Set the unit on mount or pad using team lift.
Do not install the drain elbow if the unit is located in an area where freezing can occur.

A. Select the Indoor location:

• Do not allow any heat or steam near the unit.
• Select a location where there are no obstacles in front of the unit.
• Make sure that condensate drainage can be conveniently routed away.
• Do not install near a doorway.
• Ensure that the space around the left and right of the unit is more than 4”. The unit should be installed as high on the wall as possible but allow a minimum of 4” from the ceiling.
• Use a stud finder to locate and mark stud locations for mounting and to prevent unnecessary damage to the wall.
• Install in a location that is strong enough to withstand the full weight and vibration of the unit.
• Leave enough space to allow access for routine maintenance.
• Select a location that gives easy access to removing and cleaning air filters.
• Install in a location that is 3 ft. or more away from other electrical appliances, such as televisions and audio devices.
  B. Install the Mounting Plate
• Remove plastic bag, tape, and mounting plate from the back of the indoor unit.
• Place the mounting plate on the wall in the desired location taking into account the minimum clearances necessary for proper operation.
• Using a level, verify that the mounting plate is horizontal and mark the screw locations.
• Attach the mounting plate to the wall with the supplied screws.
• Wall anchors are supplied if not able to align all screw holes with studs.
• Be sure that the mounting plate has been attached firmly and that applied weight is evenly distributed by each screw. (At least one screw in wall stud, others can use wall anchors.)
• The piping for the indoor unit may be routed to and from the unit in one of several directions: left, left rear, right, right rear, or right below. See Illustration on page 7.
• Knockouts are provided on the unit case for Left, Right, and Right Below usage.
  C. Install the Tubing
• Measure and mark the location where the piping hole is to be drilled.
• Follow these steps to move the drain pipe if the pipe location will be on the left side of the unit.
  1. Remove the stopper in the left drain hole and knockout the molded plug inside the port.
  2. Transfer the corrugate drain hose from the right side to the left side.
  3.  Insert stopper into right side drain port. Using soap as a lubricant and a small screwdriver will allow for easier seating of the stopper.
• Drill the lineset hole using a 2 1/4” hole saw. Angle the drill with a downward pitch to the outside wall so that the outside wall hole will be at least a ¼” lower than the inside hole. This allows for proper drainage of condensate.
• Install the lineset hole flange at the hole opening on the inside wall.

NOTE: The flange is prescored. It may be necessary to modify the flange to fit properly behind the wall unit housing.

D. Electrical Connections for the Indoor Unit
NOTE: Be certain all wiring complies with local building codes and NEC and that the supply voltage for this system is correct.

• Place the indoor unit on a solid work surface before making electrical connections.
• Both the outer plastic and inner galvanized steel cover plates must be removed to make the electrical connections for the indoor unit.
• Raise the front cover to access the screws for removing these covers.
• Route the 14/4 AWG wiring through the slot in the back of the unit and into the front access panel.
• Using a wire stripper, remove the insulation and separate the 4 wires.
• Make wiring connections at each terminal according to wiring diagram. Take note of the color of the wire at each terminal and ensure the wires are connected to the outdoor unit accordingly.
• Ensure each wire is under the screw terminal plate and the plate is tightened.
• Ensure the 14/4 cable is secured under the strain relief bracket.
• After the terminal block wiring is completed, replace both cover plates and lower the front casing.

E. Mount Indoor Unit to Mounting Plate

• Bundle the refrigerant piping, drain piping, and wiring with tape and carefully rout the bundle through the piping hole.
• With the top of the indoor unit closer to the wall, hang the indoor unit on the upper hooks of the mounting plate. Slide the unit slightly side to side to verify proper placement.
• Rotate the lower portion of the indoor unit to the mounting plate, and lower the unit onto the lower hooks of the mounting plate. (see illustration)
• Verify the unit is secured and flush to the wall.
• Indoor Unit installation is finished at this time.

F. Condensate Drainage Pipe

• Verify the condensate drain line has a constant pitch downward for proper water flow. There should be no kinks or rises in the tubing which may cause a trapping effect of the water (see illustration).
  Optional: Can use PVC pipe by connecting a 1” ID PVC pipe to the drain line coming out of the wall and running to desired location.

G. To Remove the Indoor Unit

• Slightly raise the entire unit.
• Pull the lower portion of the unit off the lower hooks and pull slightly away from the wall.
• Lift the upper portion of the unit off the upper hooks.

Wall Brackets

Step 3 – Installation of the Outdoor Unit

A. Prepare the Outdoor Unit for Installation

• Remove all packaging.
• Place supplied vibration pads onto outdoor unit’s feet.
• Attach the supplied drain elbow to the outdoor unit if required. Connect extension piping as needed (not supplied). (see illustration) NOTE: The drain elbow is designed with an air gap and will not sit flush to bottom of the outdoor unit.
  NOTE: 1U09AP*, 1U12AP*, 1U15AP*, 1U18AP* and 1U24AP* models will not use a drain elbow. A 3rd party pan is needed if condensate management is required by code.
  
• Remove the cover plate of the outdoor unit to expose the terminal block connections.

1. Remove Screw
2. Slide the panel down to release the clips and pull away.

B. Electrical Connections for the Outdoor Unit

WARNING
RISK OF ELECTRIC SHOCK.
Could cause injury or death.
Make sure power is off before touching wires.

NOTE: Be certain all wiring complies with local building codes and NEC and that the supply voltage for this system is correct.

• Connect the wiring for both the power source and the indoor wiring using a conduit cable bracket on the side of the outdoor unit.
• Using a wire stripper, remove the insulation and separate the wires.
• Verify that the wiring connections match the indoor connections wire for wire.
• Ensure each wire is under the screw terminal plate and the plate is tightened.
• Ensure the 14/4 control cable is secured under the strain relief bracket.
• Verify that all connections are secured

NOTE: Failure to follow the wiring guidelines can result in control board damage and communication issues (E7 error code). This includes improper wire size, use of solid core wire, midline splicing and poor terminal connections.

C. Install Copper Lineset

• The standard line set length is 25 feet. If the installation length is different, adjust the refrigerant charge by adding 0.2 oz/ft if the liquid line is 1/4”, or 0.5 oz/ft if the liquid line is 3/8”.
• See table on page 15.
• Cut the line set to length.
• Place nut over the pipe and then flare with the R- 410A flaring tool.
  NOTE: Follow standard practices for creating pipe flares. When cutting and reaming the tubing, use caution to prevent dirt or debris from entering the tubing. Remember to place nut over the tubing before flaring.
• To join the line set, directly align the tubing flare to the fitting on the other pipe. Slide the nut onto the fitting and hand tighten.
• Torque the fittings according to the specifications shown in the torque chart below.
  Forced fastening without careful centering may damage the threads and cause a refrigerant leak.

  Pipe Diameter(ǿ)	Fastening torque
  Liquid side 6.35mm(1/4″)	18N.m/13.3Ft.lbs
  Liquid/Gas side 9.52mm(3/8″)	42 N.m/30.1Ft.lbs
  Gas side 12.7mm(1/2″)	55N.m/40.6Ft.lbs
  Gas side 15.88mm(5/8″)	60 N.m/44.3Ft.lbs

  Two wrenches are required to join the flare connection; one standard wrench and one torque wrench adjusted to the proper settings.
  

• Repeat the process for attaching the other end of the line set.
  D. Leak Test
• Remove the cap on the service valve.
• Using a tank of dry nitrogen and approved regulator, charge the system with 150 psig of dry nitrogen using mini split adapter to connect the valve.
• Check for leaks at the flare fittings using soap bubbles or another detection device. If a leak is detected, make repairs to the fittings and recheck. If no leaks are detected within 3 minutes, proceed.
• Using the same tank/regulator, charge the system to 300 psig.
• Check for leaks as earlier. If no leaks are detected within 3 minutes, proceed.
• Using the same tank/regulator, charge the system to 500 psig.
• Check for leaks as earlier. Keep system pressurized for at least 20 minutes.

WARNING
Do not use acetylene, oxygen,compressed air or any mixture containing anything other than dry nitrogen. Use only dry nitrogen for pressure testing. Do not use mixtures of hydrogen containing refrigerant and air above atmospheric pressure for pressure testing, as they may become flammable and could result in an explosion. Refrigerant, when used as a trace gas, should only be mixed with dry nitrogen for pressurizing units.
Failure to follow these recommendations could result in death or serious injury as well as equipment or property damage.

E. System Evacuation
NOTE– Do not open service valve.

• Attach a manifold gauge, micron gauge, and vacuum pump to the suction line port using adapter AD-87 (see illustration).
• Evacuate the system to at least 350 microns.
• Close the vacuum pump valve and check the micron gauge. If the gauge rises 150 microns in 60 seconds, the evacuation is incomplete or there is a leak in the system. If the gauge does not rise 150 microns in 60 seconds, the evacuation is complete.
• Once evacuation is complete, remove the adapter and hose connection from the suction line port and replaced the cap.



F. Refrigerant Charging

• Add any additional refrigerant after evacuation using a digital scale.
  NOTE: Charge liquid only.
• Fill out the refrigerant charge label using indelible ink.
