SECTION XVIII: TEST OPERATION

1.Check that all tubing and wiring have been properly connected.

2.Check that the gas and liquid side service valves are fully open.

GAS LEAK TEST

Check the flare nut connections for gas leaks with a gas leak detector and/or soapy water.

RUNNING TEST

1.Turn power on by pressing "ON/OFF" button on the wireless remote control to start system operation.

2.Press MODE button to select COOL, HEAT or FAN to check the system operation.

INDOOR UNIT RUNNING TEST

1.Check if operation of each button on the remote control is working normally and check the corresponding operating indication LED on the indoor unit to make sure they match.

2.Check the operation of indoor unit louver and make you check its swinging function.

3.Check the condensate drain and make sure there are no leaks.

OUTDOOR UNIT RUNNING TEST

1.Make sure there are no abnormal noises or vibration during opera- tion.

2.Make sure you check for gas leaks.

SECTION XIX: EMERGENCY OPERATION

If the wireless remote is lost or damaged, the system can be operated using the manual switch or code switch. The system will run in Auto Run mode, and will not change the temperature setting nor the fan speed.

The manual switch can be operated as follows:

•To operate the unit, press the AUTO/STOP button once and the unit will enter into AUTO RUN mode. The microcomputer will select the (COOL, HEAT, FAN) mode automatically to maintain optimum room comfort.

•To stop the unit from operating, press the AUTO/STOP button once and the unit will shut down.

The code switch can be operated as follows:

•To operate the unit, adjust the code switch to the AUTO position and the unit will enter into AUTO RUN mode. The microcomputer will select the (COOL, HEAT, FAN) mode automatically to main- tain optimum room comfort.

•To stop the unit from operating, adjust the code switch to the STOP position and the unit will shut down.

SECTION XX: MAINTENANCE

OUTDOOR UNIT

1.Ensure power is off before cleaning.

2.It may be necessary to wash the outdoor coil more frequently if it is exposed to substances which are corrosive or which block airflow across the coil (e.g., pet urine, cottonwood seeds, fertilizers, fluids that may contain high levels of corrosive chemicals such as salts).

3.Outdoor Coil (Sea Coast) - Moist air in ocean locations can carry salt, which is corrosive to most metal. Units that are located near the ocean require frequent inspections and maintenance. These inspections will determine the need to wash the unit including the outdoor coil. Consult your installing contractor for proper intervals/ procedures for your geographic area or service contract.

4.Outdoor unit fan motor is pre-lubricated and sealed. No further lubrication is needed.

5.Visually inspect all connecting lines, joints and coils for evidence of oil leaks.

6.Check all wiring for loose connections.

7.Check for correct voltage at unit (unit operating).

INDOOR UNIT

1.Clean or change filters.

2.Check all wiring for loose connections.

3.Check for correct voltage at unit (blower operating).

4.Clean coil, if necessary.

5.Check connecting lines and coils for signs of oil leaks.

6.Check condensate line and clean, if necessary.

NOTICE

The filter must be in place and the front panel must be closed any time the unit is in operation.

SECTION XXI: INSTALLATION AND MAINTENANCE OF HEALTHY FILTER (ACCESSORY)

INSTALLATION OF HEALTHY FILTER (ACCESSORY)

1.Lift up the front panel from its two ends and remove the factory sup- plied air filter as shown in Fig. A.

2.Attach the healthy filter to the air filter as shown below in Fig. B.

3.Install the air filter properly as shown below in Fig. C and then close the panel.

22 SEER specifications

Johnson Controls has long been a leader in the heating, ventilation, and air conditioning (HVAC) industry, consistently pushing the boundaries of energy efficiency and comfort. One of their standout offerings is the 22 SEER (Seasonal Energy Efficiency Ratio) air conditioning system, which boasts advanced technologies designed to deliver optimal performance while minimizing energy consumption.

At the heart of the Johnson Controls 22 SEER system is its innovative compressor technology. The variable-speed compressor allows for precise temperature control by adjusting the cooling output according to the specific demands of your space. This means that instead of constantly turning on and off, the system can operate at lower speeds for longer periods, ensuring even cooling and reducing energy bills.

In addition to the compressor, the 22 SEER unit employs high-efficiency coils and a superior refrigeration system that work in tandem to enhance performance. These components are designed to maximize heat transfer, enabling the system to cool your home more effectively and efficiently.

Another notable feature of the Johnson Controls 22 SEER system is its smart technology integration. With a focus on convenience and energy management, these units often come equipped with Wi-Fi connectivity, allowing homeowners to control their HVAC systems remotely using a smartphone app. This capability enhances user experience by enabling real-time monitoring and scheduling, ultimately leading to smarter energy use.

The design of the units also reflects an emphasis on quiet operation. Noise reduction technologies, including sound-dampening features, ensure that the system operates quietly in the background, enhancing indoor comfort without disruptive sounds.

Durability is another standout characteristic of the Johnson Controls 22 SEER systems. These units are built with high-quality materials and rigorous testing standards, ensuring they can withstand harsh weather conditions and provide reliable performance over the years.

Moreover, the 22 SEER air conditioning systems contribute to environmental sustainability. By using less energy, they not only lower utility costs but also reduce the carbon footprint of homes, aligning with growing consumer preferences for eco-friendly solutions.

Overall, the Johnson Controls 22 SEER air conditioning system represents a significant leap forward in HVAC technology. Its blend of efficiency, innovative features, and user-friendly technologies makes it an ideal choice for environmentally-conscious homeowners seeking comfort without compromise. Whether upgrading an existing system or investing in a new one, the 22 SEER unit stands out as a prime example of luxury, efficiency, and sustainability in the HVAC market.
