tie at ey The unit body must be completely aligned with the hole. Ensure that the unit and the hole are the same size before moving on. 2. Install and fit pipes and wires after you have finished installing the main body.When choosing where to start, determine the direction of the pipes to be drawn out. Especially in cases where there is a ceiling involved, align the refrigerant pipes, drain pipes, and indoor and outdoor lines with their connection points before mounting the unit. 3.
Step 4: Adjust the air inlet direction Step 5: Fresh air duct installation (from rear side to under-side). Dimension : 1. Take off the ventilation panel and flange. Duct joint for fresh air 2. Change the mounting positions of the ventilation panel and air return flange. Ventilation panel Fig. 4.14 Step 6: Motor and drain pump maintenance (the rear ventilated panel is used as an example) Motor maintain: 1. Take off the ventilated panel. 2. Take off the blower housing. 3. Take off the motor.
Outdoor Unit Installation Instructions Step 1: Select installation location. The outdoor unit should be installed in the location that meets the following requirements: 6 Place the outdoor unit as close to the indoor unit as possible. B Ensure that there is enough room for installation and maintenance. 6 The air inlet and outlet must not be obstructed or exposed to strong wind.

Be sure to keep the unit unobstructed 3. Rotate the drain joint 90° until it clicks in place in at least two of the three directions (M,N, P} facing the front of the unit . A {See Fig 510) 4.
The drainpipe is used to drain water away from the unit. Improper installation may cause unit and property damage. + Insulate all piping to prevent condensation, which could lead to water damage. « theft drainpipe is bent or installed incorrectly, water may leak and cause a water-level switch malfunction. «In HEAT mode, the outdoor unit will discharge water. Ensure that the drain hose is placed In an appropriate area to avoid water damage and slippage. + DO NOT pull the drainpipe forcefully.
Lila al 3. Using a 2.5" (65-mm) 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 0.5” (12mm). This will ensure proper water drainage (See Fig. 6.5). Place the protective wall cuff in the hole. This protects the edges of the hole and will help seal it once you finish installation. Wall Outdoor Indoor =05 Inch /12mm Fig. 6.
Safety Precautions Notes On Pipe Length and Elevation Ensure that the length of the refrigerant pipe, the number of bends, and the drop height between the indoor and outdoor units meets the requirements shown in Table 7.1: + All field piping must be completed by a licensed technician and must comply with the local and national regulations. Table 7.1: The Maximum Length And Drop » When the air conditioner is installed in a small room, measures mist be taken to Height Based on Models. (Unit: ft/m.

+ While connecting the wires, please strictly follow the wiring diagram. + The refrigerant circuit can become very hot. Keep the interconnection cable away from the copper tube. 4. Clamp down the cable with the cable clamp. The cable must not be loose or pull on the u-lugs. 5. Reattach the electric box cover. Using the wire control to set external static pressure (some models) + You can use the unit's automatic airflow adjustment function to set external static pressure.
Safety Precautions + Use a vacuum pump with a gauge reading lower than -0.1MPa and an air discharge capacity above 40L/min. + The outdoor unit does not need to be vacuumed. DO NOT open the outdoor unit's gas and liquid stop valves. + Ensure that the Compound Meter reads -0,1MPa or below after 2 hours. If after three hairs the gauge reading is still above -0.1MPa, check if there Is a gas leak or water inside the pipe.
Note On Adding Refrigerant «+ Refrigerant charging must be performed after wiring, vacuuming, and the leak testing. » DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system. Doing so can damage the unit or impact it's functioning. + Charging with unsuitable substances may cause explosions aor accidents. Ensure that the appropriate refrigerant is used. «Refrigerant containers must be opened slowly. Always use protective gear when charging the system.
Before Test Run A test run must be performed after the entire system has been completely installed. Confirm the following points before performing the test: a) Indoor and outdoor units are properly installed. b) Piping and wiring are properly connected. c) No obstacles near the inlet and outlet of the unit that might cause poor performance or product malfunction. d) Refrigeration system does not leak. e) Drainage system is unimpeded and draining to a safe location.
