Refrigerant Piping Connection Step 1: Prepare exterior wall hole Before the refrigerant piping can be installed and connected to the indoor and outdoor units, some additional steps are required to prepare the exterior. 1. Install finishing ring/cap to exterior portion of the wall hole. 2. Place your hand on the underside of the piping coming through the exterior wall hole (from indoor unit), close to the wall.
Refrigerant Piping Connection Step 3: Connect Line Set to Indoor Unit 3.1 Tools needed NOTE: Depending on the capacity rating of your unit, (9K, 12K, 18K, 24K) the wrench sizes needed will vary, refer to the table below (the unit uses metric sizes, the standard sizes listed are approximations). Based on the availability of wrenches in some of the sizes needed, the recommended method is to use crescent (adjustable-type) wrenches that can be adjusted to fit the size each step requires. .
Refrigerant Piping Connection TORQUE REQUIREMENTS 1. Excessive torque can break the nut or damage the refrigerant piping. You must not exceed the torque requirements shown in the table below. 2. You can find the coupling size and torque rating by looking for the stamped part number on the connector and using it to find the corresponding torque rating in the table below. 3. Note there may be differences in Torque Wrenches (i.e.

Refrigerant Piping Connection Step 5: Opening the refrigerant valves of the outdoor unit 1. Using the images below as a guide, remove the cover on the top valve, using a 19 mm open-ended wrench or a crescent (adjustable-type) wrench. Then, insert a 5 mm Allen key and open the valve by turning it counter-clockwise as far as it will go. DO NOT force it. The valve is now open. Screw the cover back onto the top valve and tighten it well to ensure that it is properly sealed. 2.
Refrigerant Piping Connection Step 6: Connect Drain Pipe Make sure there are NO kinks or dents in the hose to ensure proper drainage. In this step you will connect the drain hose extension to the drain hose exiting from the indoor unit that is within the piping bundle you wrapped in the previous steps. 1. Securely connect the drain hose extension to the drain piping from the indoor unit. Fig. 6.2a NOT CORRECT KINKS in the drain hose will create water traps. 2. Using example Fig. 6.
Refrigerant Piping Connection Step 7: Wrap piping connections In this step you will insulate the exposed line connections coming from the indoor air handler with the supplied sound deadening pads and insulation. Then wrap the line set from the outdoor unit to the wall hole with the supplied Non-Adhesive U.V. Tape.

Outdoor Unit Wiring Diagram is located on Cover wire cover on Fig. 7.2 2. Remove the retaining nut from the end of the DIYPRO™ Cable that you fed through the wall hole earlier in the installation, as shown in the image below.
Electrical Connections 4. Now, secure the DIYPRO™ Cable to the outdoor condenser by pushing the threaded end of the cable into the hole and reinstalling the retaining nut on the end of the cable. Please refer to the images below. 6. Finally, reinstall the electrical wiring cover and secure it using the 3 screws you removed from it. 5. Then, you will connect the wires to the terminal block. Each wire should be numbered and correspond with a connection port on the terminal block.
88 Refrigerant Piping Connection There are two different methods to check for gaseous leaks. Please refer to the illustration below for the areas to check for leaks. Manual. Soap and Water Method BEFORE TEST RUN Measure grounding resistance by visual detection and with a grounding resistance tester. Grounding resistance must be less than 0.1Ω.
Refrigerant Piping Connection Test Run 9 Before Test Run PASS/FAIL Only perform test run after you have completed the following steps: No electrical leakage • Electrical Safety Checks - Confirm that electrical system is safe and operating properly. Unit is properly grounded • Gas Leak Checks - Check all flare nut connections and confirm that the system is not leaking. • Confirm that gas and liquid (high and low pressure) valves are fully open.
Test Run DOUBLE-CHECK PIPE CONNECTIONS During operation, the pressure of the refrigerant circuit/piping will increase. This may reveal leaks that were not present during your initial leak check. Take time during the Test section for instructions. 5. Manual Control Button a. Fig. 9.1 operating temperature. b. IF AMBIENT TEMPERATURE IS BELOW 60°F (16°C) If the ambient temperature is below 60°F (16°C), the remote controller cannot be used to turn on the COOL function.
10 The following events may occur during normal operation, and may not indicate a malfunction. Symptom Possible Cause Unit does not turn on when pressing the ON/OFF button The protection circuit will prevent the compressor from operating for roughly 3 minutes, after a sudden ON-OFF operation of the power supply, in order to prevent the unit from being overloaded. The unit changes from COOL/HEAT mode to FAN mode The unit may change its setting to prevent frost from forming on the unit.
Symptom Possible Causes Temperature setting may be higher than ambient room temperature Lower temperature setting The heat exchanger on the indoor unit is dirty Clean the affected heat exchanger Remove the filter and clean it according to the instructions The air filter is dirty The air inlet or outlet of either unit is blocked Door and windows are open Poor Cooling Performance Solution Excessive heat is generated by sunlight Turn the unit off , remove the obstruction and turn it back on Make sure that
Error Codes When the indoor unit encounters a recognized error on different models , 1. the running LED with flash in a corresponding series, the timer LED may turn on or begin flashing; 2. an error code will be displayed; 3. both 1 and 2.
