INDOOR UNIT INSTALLATION

PREPARE REFRIGERATION LINES
Refrigeration lines and wiring can be routed from the indoor unit several different ways using the cut-out access pieces on the back of the unit.
Bend the refrigeration lines carefully to the position needed to align with the drilled piping hole.

HANG INDOOR UNIT
Bundle the refrigeration lines, drainage hose, and wiring conduit attached to the indoor unit and wrap them securely for enough length to extend through the piping hole to the exterior of the building.
Note: leave remainder unwrapped to allow for remaining step in installation of the outdoor unit and connecting the indoor unit to the outdoor unit. Carefully push bundled lines through the piping hole.
Hang the unit on the wall by hooking the mounting slots of the unit over the upper tabs of the rear panel.
Check to make sure the: unit is properly secured – it should feel firmly attached to the wall, and you should not be able to slide it to the right or left.

OUTDOOR UNIT INSTALLATION

CONNECT REFRIGERATION LINES
Align the center of the piping flare with the relevant valve.
Use standard A/C practices to attach the connection pipes to the proper pipes of the bundled lines coming through the wall from the indoor unit.
Tighten the flare nut of the connection pipes using a spanner and torque wrench. (see diagram)

Note
Do not over-tighten flare nuts, or the connection may be damaged. Unit is charged with enough R410A Refrigerants for a standard designed length. For longer line set lengths additional charge must be

WEIGHED in per Table 2.

AIR PURGING AND PRESSURE TEST

• Remove bonnet (cover) of gas valve on outdoor unit.
• Charge system with Nitrogen to 100 PSI and check for leaks. Evacuate Nitrogen.
• Connect the gas valves of a vacuum gauge, vacuum pump, and outdoor unit(see diagram). Start the vacuum pump and allow to run for at least 30 minutes at a level of 500 microns or less.
• Shut off the vacuum and continue to monitor vacuum gauge for another 15 minutes. The pressure should not rise above 800 microns. lf a vacuum of 500 microns cannot be obtained, or if it rises above
• 800 microns during the l5-minute monitoring period, pressurize the system with nitrogen and look for leaks. Repair any leaks that are found and repeat the vacuum testing.
• Close the valves to the vacuum pump and gauge and disconnect from the outdoor unit.
• Tighten bonnet (cover) of gas valve and open gas and liquid valves completely.

SYSTEM TESTING

• Before testing the system, ensure that cut-off valves of the connection pipes are opened and that all debris (such as packing scraps, debris, etc.) are clear from the unit.
• Switch on power to the system and press the ”ON/OFF” button on the remote control to activate the indoor unit.
• Press ”MODE” button repeatedly, taking a moment on each setting to ensure that system functions in all modes.
• If the remote control is lost, emergency run operation can be initiated by pressing the button in the upper right corner of the indoor unit under the cover panel. (see diagram) 

INSTALLATION VERIFICATION

• Have both units been securely and firmly installed?
• Are all piping connections secure?
• Have the refrigeration lines been sufficiently insulated?
• Have you verified the length of the connection pipes and the refrigerant capacity? Have you conducted all leakage and system tests?
• Does the unit drain properly?
• Are all electrical connections in compliance with local standards?
• Has the unit been properly grounded?
• Is the power cord as specified?

PRINCIPLE

COOLING MODE

Principle
The air conditioner absorbs heat from indoor air and transmits it outdoors for discharge, hence to decrease the indoor ambient temperature. The cooling capacity decreases with the rise of outdoor ambient temperature.

Anti-freeze Function
If the air conditioner is running under low-temperature cooling mode, frost will appear on the surface of indoor heat exchanger. When the temperature of indoor heat exchanger is decreased to 32℉ or below, the microcomputer of indoor unit will stop the compressor to protect the complete unit.

HEATING MODE

Principle
The air conditioner absorbs heat from outdoor air and transmits it indoors for emission, hence to increase the air temperature in the room. The heating capacity decreases with the reduction of the outdoor ambient temperature.

It takes only a short time for this type of hot air circulating system to increase the indoor temperature.
Use this air conditioner with other heating equipment if the outdoor temperature is extremely low.

Defrost
When the outdoor temperature is low but the humidity is high, the heat exchanger of outdoor unit may frost after the air conditioner has run for a period of time. This will decrease the heating effect.
In this case, auto defrost function will be activated and the heating mode will temporarily stop for 8-10 minutes.
Both the indoor fan and outdoor fan will be stopped during auto defrost.
During defrost, the indicator on indoor unit will blink and steam might flow from the indoor unit. This is caused by the defrost mode.
Heating mode will automatically resume upon completion of defrost process.

Anti-Draft Protection
If the following conditions are present, the control circuitry in the unit will prevent the indoor fan from operating:

1. Heat mode (delay 3 minutes).
2. Auto defrost (delay 3 minutes after defrost cycle has completed).
3. If the outdoor ambient temperature falls below 20 ℉, indoor fan will not operate.

Air Conditioner is Unable to Run Normally
Protection device might be activated within such temperature range as Table 3, so that the unit might be stopped.

| Heating Mode| Cooling Mode| Dehumidify Mode
---|---|---|---
Outdoor Temperature| ≥75°F or ≤20°F| ≥109°F| N/A
Room Temperature| ≥80°F| ≤70°F| ≤64°F

– Table 3 –

NOTE: If the unit operates in cooling or humidify mode for a long period that the relative humidity is higher than 80% (while door and windows open), dew might drop near the air outlet.
