Attach the mounting plate to the wall using appropriate screws or anchors Based on the wall Type. Use a level to ensure that the plate is perfectly leveled. This step is crucial to provide an even surface for mounting the evaporator unit and ensure optimal performance.
4.3 Securing the Evaporator Unit
Place the evaporator unit, also known as the indoor unit, on the mounting plate. Rest it securely on the plate ensuring a stable mount. Follow the manufacturer's instructions for securing the unit to the plate. This step ensures the stability of the unit and prevents any accidents or damages.
4.4 Connecting the Signal Wire
Slide the wiring cover plate to access the terminal block of the evaporator unit. Remove the strain relief, allowing the signal cable's easy passage. Fish the signal cable from the back to the front of the unit. Connect the appropriate wires to the corresponding terminals on the terminal block, following the provided Diagram. Once the connections are secure, replace the cover plate and screw it down firmly.
4.5 Wiring the Terminal Block
With the signal wire connected, it is essential to connect the remaining wires to the terminal block. Match the wire colors with the correct labels on the block, following the provided diagram. Attach all the wires securely and replace the cover, ensuring a tight fit. Proper wiring is crucial for the unit's functionality and ensures a safe and efficient installation.
5. Connecting the Refrigerant Lines
Locate the refrigerant lines on the backside of the indoor unit. Use an open-ended wrench to remove the plastic caps from the lines. Twist the caps off and set them aside. The refrigerant lines consist of a large line and a small line. Connect the corresponding lines together by removing the yellow caps. Ensure a secure connection by tightening the lines firmly. This step ensures the proper flow of refrigerant and efficient cooling performance.
6. Drilling a Hole for Cable Entry
To allow for the passage of the cables from the indoor unit to the outdoor compressor, you will need to drill a hole through the wall. Use a long drill bit that can penetrate both the interior and exterior walls. Start by drilling from the inside out, tilting the drill downwards. Continue drilling from the outside in, tilting the drill upwards. This technique allows proper drainage and prevents Water from entering the space.
7. Installing the Compressor
7.1 Selecting a Site for the Compressor
Choosing the right location for the outdoor compressor is crucial for optimal performance. Ensure that the site has ample airflow to prevent any obstructions to the unit. Attach the compressor to a concrete slab or use sleeve anchors for installation. Different mounting methods are available, but it is essential to secure the unit properly for stability.
7.2 Attaching the Compressor to the Wall
Attach the compressor to the selected surface using appropriate screws or anchors based on the wall type. Use a hammer drill to Create holes for the screws or anchors. Securely fasten the compressor to the wall, ensuring it is stable and level. Properly mounting the compressor guarantees optimal functionality and longevity.
8. Routing and Securing the Cables
After installing the indoor and outdoor units, it is crucial to route and secure the cables properly. Ensure that the cables are free from any strain or tension. Use gum sealer or a similar product to seal any gaps around the cable entry point. This step prevents any water or debris from entering the space. Secure the cables using tape or cable ties, keeping them neat and organized. Proper cable routing and securing prevent any interference with the unit's performance and ensure a clean installation.
9. Connecting the Coolant Lines and Signal Wire
Attach the coolant lines and signal wire to the outdoor unit following the manufacturer's instructions. Ensure that the correct connections are made by matching the line sizes and valve types. Use adjustable wrenches or open-ended torque wrenches for tightening the connections. Connect the signal wire by matching the wire colors to the correct terminals on the terminal block. Proper connections guarantee efficient refrigerant flow and reliable signal transmission.
10. Powering Up the System
Before powering up the system, ensure that it has a dedicated circuit on a 20 amp double pole breaker. Consult an electrician if you are not confident in your electrical skills. Connect the power supply from the breaker panel to an emergency shutoff near the compressor. From the emergency shutoff, run the power supply to the compressor unit. Following all safety guidelines, power up the system and ensure successful electrical connection.
11. Vacuuming the Line
To prepare the system for refrigerant circulation, it is essential to evacuate the air and moisture from the refrigerant lines. Connect a vacuum Pump and a gauge to the refrigerant charging vent on the outdoor unit. Turn on the vacuum pump and allow it to run for 10 to 15 minutes. Ensure that the gauge remains steady at the recommended pressure level. This step removes any impurities and ensures optimal system performance.
12. Checking for Leaks
After vacuuming the line, close the low-pressure valve and turn off the vacuum pump. Wait for five minutes and check for any changes in pressure. If the pressure remains steady, remove the manifold gauge and valve caps. Inspect the connections for leaks by applying soapy water. If bubbles are present, tighten the connections. If no bubbles are observed, proceed to the next step.
13. Final Steps and Testing
With the system properly connected and vacuumed, it is time for the final steps. Ensure that the cables and drainage line are secured and not obstructing the unit. Adjust the drainage line to point towards the appropriate area for water discharge. Secure any access panels, covers, or caps that were removed during the installation.
