INSTALLATION

Please review these common mistakes and read the full installation manual prior to performing the installation. If you have any questions please contact us prior t installing the system.

Make sure to supply the correct voltage. Most mini splits are 220 volt systems. However there are some 12000 btu and lower mini split systems that are 110 voltage. Make sure you know the correct voltage and amperage that your system needs and wire it correctly.

The 14/4 wire is included with the DIY mini splits and it is already connected to the air handler make sure to check what color wire is connected to what numbered terminal at the indoor unit and match that color wire to the same numbered terminal at the outdoor unit.

When connecting the pre-charged refrigerant lines make sure to connect the larger diameter refrigerant line to the larger valve (bottom valve) on the outdoor unit and the larger diameter refrigerant line to the larger line at the indoor unit. This is a critical step in the process. Please disregard the color coding and ensure that the larger refrigerant line connects to the larger connection at both the indoor and outdoor units and make sure that the smaller refrigerant line is connected to the smaller (top) valve on the outdoor unit and to the smaller line on the indoor unit.

ALWAYS VERIFY WHERE THE LINE AND LOAD LUGS ARE IN YOUR DISCONNECT BOX.

The position can vary. the wiring below is based on LOAD, LINE, LINE, LOAD in the disconnect box. For a 220 volt system make sure when installing your electrical whip to the disconnect box that you connect the black and red power wires to the two load lugs in the disconnect box and connect the ground wire (green) to a ground lug. Make sure to connect the incoming power wires from the breaker (typically black and red) to the line lugs in the disconnect and the ground wire (bare) to a ground lug.

ALWAYS VERIFY WHERE THE LINE AND LOAD LUGS ARE IN YOUR DISCONNECT BOX.

The position can vary. The wiring below is based on LOAD LINE LINE LOAD in the disconnect box. For a 110 volt system make sure to connect the black wire from the whip to the left side load lug. Connect the ground (green) wire to a ground lug. Then wire nut the neutral (red) wire from the whip to the incoming neutral (white) wire from the breaker. Make sure to connect the incoming power (black) wire from the breaker to the disconnect left side, line lug and the ground (bare) wire to a ground lug.

Make sure to open the valves at the outdoor unit after the refrigerant lines are correctly connected at the indoor and outdoor unit and before system startup. Failure to do so can cause damage to the system.

Indoor Unit Installation

Installation Instructions – Indoor unit

PRIOR TO INSTALLATION
Before installing the indoor unit, refer to the label on the product box to make sure that the model number of the indoor unit matches the model number of the outdoor unit.

Step 1: Select installation location Before installing the indoor unit, you must choose an appropriate location. The following are standards that will help you choose an appropriate location for the unit.
Proper installation locations meet the following standards:

Good air circulation
Convenient drainage
Noise from the unit will not disturb other people Firm and solid—the location will not vibrate Strong enough to support the weight of the unit
A location at least one meter from all other electrical devices (e.g., TV, radio, computer)

DO NOT install unit in the following locations:

Near any source of heat, steam, or combustible gas
Near flammable items such as curtains or clothing
Near any obstacle that might block air circulation
Near the doorway
In a location subject to direct sunlight

NOTE ABOUT WALL HOLE:

If there is no fixed refrigerant piping:
While choosing a location, be aware that you should leave ample room for a wall hole (see Drill wall hole for connective piping step) for the signal cable and refrigerant piping that connect the indoor and outdoor units. The default position for all piping is the right side of the indoor unit (while facing the unit).
Refer to the following diagram to ensure proper distance from walls and ceiling:

Step 2: Attach mounting plate to wall
The mounting plate is the device on which you will mount the indoor unit.

•  Remove the screw that attaches the mounting plate to the back of the indoor unit.
• Secure the mounting plate to the wall with the screws provided. Make sure that mounting plate is flat against the wall.

NOTE FOR CONCRETE OR BRICK WALLS:

If the wall is made of brick, concrete, or similar material, drill 5mm- diameter (0.2in-diameter) holes in the wall and insert the sleeve anchors provided. Then secure the mounting plate to the wall by tightening the screws directly into the clip anchors.

1. Step 3: Drill wall hole for connective pipingDetermine the location of the wall hole based on the position of the mounting plate. Refer to Mounting Plate Dimensions.
2. Using a 90mm(3.54in) core drill, drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 5mm to 7mm (0.2-0.275in). This will ensure proper water drainage.
3. Place the protective wall cuff in the hole. This protects the edges of the hole and will help seal it when you finish the installation process.

CAUTION
When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.

MOUNTING PLATE DIMENSIONS
Different models have different mounting plates. For the different customization requirements, the shape of the mounting plate may be slightly different. But the installation dimensions are the same for the same size of indoor unit.
See Type A and Type B for example:

While there are 7 mounting holes on many brackets it is common for only 5 screws to be included in the hardware packet. That is an appropriate number for installation. Please secure the bracket in those cases with 3 screws in the top and 2 in the bottom.

Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating sleeve attached to the back of the unit. You must prepare the piping before passing it through the hole in the wall.

Unit is adjustable
Keep in mind that the hooks on the mounting plate are smaller than the holes on the back, of the unit. If you find that you don t have ample room to connect embedded pipes to the indoor unit, the unit can be adjusted left or right by about 30-50mm (1.25-1.95in), depending on the model

Tools needed
You will require the following tools to carry out this installation work correctly:

• 1x open-ended spanner, 19 mm
• 1x open-ended spanner, 22 mm/24mm
• 1x open-ended spanner, 24 mm/27mm
• 1x Allen key, 5 mm
• 1x Philips screwdriver
• 1x leak detection spray or alternatively soap suds (water/detergent mix)

Important information

• Follow the detailed instructions for connecting the refrigerant pipes to the indoor unit and outdoor unit. We can only provide a warranty if the lines are installed correctly as described in the instructions.
• Do not remove the sealing caps and stoppers until immediately before you install the lines.
• To prevent leaks, ensure that the quick-release screw connections are absolutely free of dirt. Moisture or foreign bodies will adversely affect the function of the quick-release connectors, leading to a risk of refrigerant loss (not covered by the warranty).
• Only install refrigerant lines outdoors in dry weather.
• The refrigerant lines must not be installed and then plastered over.
• Please make sure that refrigerant is never allowed to enter the environment. Improper handling of refrigerant may be harmful to health. Always wear work gloves and goggles when handling refrigerant.
• Do not smoke during the installation work. The equipment must never be operated without the refrigerant lines connected, otherwise the equipment will be damaged immediately.
• The screw connections may only be tightened using the appropriate open-ended spanner.
• Remember that if they are tightened with too little torque, they will leak, but if they are tightened with too much torque, the screw connections may suffer damage. If you should not be confident about connecting the refrigerant line connectors yourself, it is imperative that you contact your customer service team or a refrigeration contractor.

Important! The EQ valves are only designed for one-time installation. Their seal can not be guaranteed if they are installed on more than one occasion. This will also void the warranty.

Connecting the refrigerant pipes to indoor unit. Please disregard the color code and make sure that you connect the smaller pipe to the smaller fitting and the larger pipe to the larger fitting at the indoor and outdoor units

1. Do not remove the plastic seals from the indoor equipment and the appropriate refrigerant pipe until immediately before you connect them.

2. Align the refrigerant pipes correctly,make sure the dimensions of the connecting refrigerant pipe are the same. Place the screw connector on the refrigerant pipes just on to the thread on the indoor equipment and tighten the first few threads by hand. IMPORTANT: Before you continue, it is essential that you read the following instructions carefully.

3. Hold the points marked “1”using an open-ended spanner and turn the nuts only at the points marked ” 2″ using an open-ended spanner (Select the appropriate spanner according to the dimensions of the connector).

4. Ensure that the screw connectors do not skew as you tighten them and work quickly.
   IMPORTANT: Since the coupling works with tapping rings, it may leak if you undo and reconnect the pipes.
   This will also void the warranty.

5. After finishing the connection, use the tape to wrap the refrigerant pipe and connecting cable together.
   NOTE: In North America, the cable should be protected by an applicable conduit.

6. After finishing connecting the couple of the quick connectors, pass drain hose and refrigerant pipes through the wall hole as shown below.
   NOTE: The quick connector parts must be placed outside of room. Using wall hole sleeve, cap and neoprene to seal the wall hole.

7. In order to prevent the quick connector parts from being exposed in the air, the sound deadening pads are supposed to be used during the installation.

8. Wrap up the quick connectors with the sound deadening pads, pack down the pads solid as tightly as shown below.

9. Then wrap up the connectors with the black insulation material, for the top exposed part, use the white insulation material (supplied in Accessories box) to wrap it up completely as shown below.

10. At last, use the tape to wrap the refrigerant pipe and connecting cable together.
    NOTE: In North America, the cable should be protected by an applicable conduit.

NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor unit from right-rear side:

CAUTION
Be extremely careful not to dent or damage the piping while bending them away from the unit. Any dents in the piping will affect ,the unit s performance.

Step 5: Connect drain hose
By default, the drain hose is attached to the left-hand side of unit (when you’re facing the back of the unit). However, it can also be attached to the right-hand side. To ensure proper drainage, attach the drain hose on the same side that your refrigerant piping exits the unit. Attach drain hose extension (purchased separately) to the end of drain hose.

•  Wrap the connection point firmly with Teflon tape to ensure a good seal and to prevent leaks.
  For the portion of the drain hose that will remain indoors, wrap it with foam pipe insulation to prevent condensation.
  Remove the air filter and pour a small amount of water into the drain pan to make sure that water flows from the unit smoothly.

NOTE ON DRAIN HOSE PLACEMENT
Make sure to arrange the drain hose according to the following figures..

DOUBLE-CHECK PIPE CONNECTIONS
During operation, the pressure of the refrigerant circuit will increase. This may reveal leaks that were not present during your initial leak check. Take time during the Test Run to double-check that all refrigerant pipe connection points do not have leaks. Refer to Gas Leak Check section for instructions.

5. After the Test Run is successfully completed, and you confirm that all checks points in List of Checks to Perform have PASSED, do the following
   a. Using remote control, return unit to normal operating temperature.
   b. Using insulation tape, wrap the indoor refrigerant pipe connections that you left uncovered during the indoor unit installation process.

IF AMBIENT TEMPERATURE IS BELOW 17°C (63°F)
You can’t use the remote controller to turn on the COOL function when the ambient temperature is below 17°C(63°F). In this instance, you can use the MANUAL CONTROL button to test the COOL function.

1. Lift the front panel of the indoor unit, and raise it until it clicks in place.
   2. The MANUAL CONTROL button is located on the right-hand side of the unit. Press it 2 times to select the COOL function.
