Precautions for handling units for use with R410A
WARNING
Keep electrical parts away from water.
Wet electrical parts pose a risk of electric shock, smoke, or fire.
Securely attach the control box cover.
If the cover is not installed properly, dust or water may infil-trate and pose a risk of electric shock, smoke, or fire.
Only use the type of refrigerant that is indicated on the unit when installing or relocating the unit.
Infiltration of any other types of refrigerant or air into the unit may adversely affect the refrigerant cycle and may cause the pipes to burst or explode.
When installing the unit in a small space, take appropriate precautions to prevent leaked refrigerant from reaching the limiting concentration.
Leaked refrigerant gas will displace oxygen and may cause oxygen starvation. Consult your dealer before installing the unit.
Consult your dealer or a qualified technician when moving or reinstalling the unit.
Improper installation may result in water leakage, electric shock, or fire.
After completing the service work, check for a refrigerant leak.
If leaked refrigerant is exposed to a heat source, such as a fan heater, stove, or electric grill, toxic gases will be gener-ated.
Do not try to defeat the safety features of the unit.
Forced operation of the pressure switch or the temperature switch by defeating the safety features for these devices, or the use of accessories other than the ones that are recom-mended by Mitsubishi Electric may result in smoke, fire, or explosion.
Consult your dealer for proper disposal method.
Do not use a leak detection additive.
CAUTION
Do not use the existing refrigerant piping.
A large amount of chlorine that may be contained in the re-sidual refrigerant and refrigerator oil in the existing piping may cause the refrigerator oil in the new unit to deteriorate.
Use refrigerant piping materials made of phosphorus deox-idized copper. Keep the inner and outer surfaces of the pipes clean and free of such contaminants as sulfur, oxides, dust, dirt, shaving particles, oil, and moisture.
Contaminants in the refrigerant piping may cause the refrig-erator oil to deteriorate.
Store the piping materials indoors, and keep both ends of the pipes sealed until immediately before brazing. (Keep el-bows and other joints wrapped in plastic.)
Infiltration of dust, dirt, or water into the refrigerant system may cause the refrigerator oil to deteriorate or cause the compressor to malfunction.
Use a small amount of ester oil, ether oil, or alkyl benzene to coat flares and flanges.
Infiltration of a large amount of mineral oil may cause the re-frigerator oil to deteriorate.
Charge the system with refrigerant in the liquid phase.
If gaseous refrigerant is drawn out of the cylinder first, the composition of the remaining refrigerant in the cylinder will change and become unsuitable for use.
Only use R410A.
The use of other types of refrigerant that contain chloride may cause the refrigerator oil to deteriorate.
Use a vacuum pump with a check valve.
If a vacuum pump that is not equipped with a check valve is used, the vacuum pump oil may flow into the refrigerant cy-cle and cause the refrigerator oil to deteriorate.
Prepare tools for exclusive use with R 410A. Do not use the following tools if they have been used with the conventional refrigerant: gauge manifold, charging hose, gas leak detec-tor, check valve, refrigerant charge base, vacuum gauge, and refrigerant recovery equipment.
If the refrigerant or the refrigerator oil that may be left on these tools are mixed in with R410A, it may cause the refrigerator oil in the new system to deteriorate. Infiltration of water may cause the refrigerator oil to deteriorate.Leak detectors for conventional refrigerants will not detect an R410A leak because R410A is free of chlorine.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of the refrigerant in the cylinder will change and become unsuitable for use.
Exercise special care when handling tools for use with R410A.
Infiltration of dust, dirt, or water into the refrigerant system may cause the refrigerator oil to deteriorate.

1) Summary of linear expansion valve (LEV) operationThe LEV is operated by a stepping motor, which operates by receiving a pulse signal from the indoor control board.The LEV position changes in response to the pulse signal.
Indoor control board and LEV connection
Pulse signal output and valve operation
The output pulse changes in the following order:When the valve closes 1 -> 2 -> 3 -> 4 -> 1When the valve opens 4 -> 3 -> 2 -> 1 -> 4When the valve position remains the same, all output signals will be OFF.If any output signal is missing or if the signal remains ON, the motor vibrates and makes clicking noise.

2) LEV operation
When the power is turned on, a pulse signal of 2200 pulses is output (valve closure signal), to bring the valve to position A.When the valve is operating normally, it is free of vibration noise. If the valve locks or when it goes from point E to A in the figure, it makes louder noise than would be heard when there is an open phase. Check for abnormal sound/vibration by placing the metal tip of a screwdriver against the valve and the handle side against your ear.
3) Troubleshooting
(a) Close
(b) Open
(c) Fully open valve (2000 pulses)
(d) No. of pulses

Symptom Checking Criteria Remedy
Circuit failure on the microcomputer
Disconnect the connectors on the control board, and connect LEDs to test the cir-cuit as shown below.
Pulse signals are output for 10 seconds when the main power is turned on. If there are LEDs that do not light up at all or remain lit after the pulses are turned off, there is a problem with the driving circuit.
Replace the in-door control board if driving circuit failure is detected.
Locked LEV The motor will idle and make small clicking noise if it is run while the LEV is locked. If this clicking noise is heard both when the valve is fully closed and while it is being opened, it indicates a problem.
Replace the LEV.
Disconnected or shorted LEV motor coils
easure the resistance between the coils with a tester (red-white, red-orange, brown-yellow, brown-blue). The normal range of resistance is 150 Ω 10%
Replace the LEV.

(4) Drain-up mechanismMeasure the resistance between the terminals with a tester. (coil temperature 20°C)
(5) Drain float switch (CN4F)Disconnect the connector, and measure the resistance between terminals with a tester.
Valve closure fail-ure (leaky valve)
To check the LEV on the indoor unit, check the indoor unit liquid pipe temperature that appears on the operation monitor on the outdoor unit's multi control board while operating the indoor unit in question in the FAN mode and the other indoor units in the cooling mode.
Replace the LEV if the amount of leakage is great.
(A) Termistor (TH21)
Normally, the LEV is fully closed while the unit is in the FAN mode. If the valve is leaky, liquid pipe thermistor reading will be lower than normal. If it is significantly lower than the inlet temperature on the remote controller, valve closure failure is suspected. If the amount of leakage is insignificant, replacement of LEV is unnec-essary unless it is causing a problem.
Misconnections of connectors or con-tact failure
Perform a visual check for disconnected connectors.Perform a visual check of lead wire color.
Disconnect the connectors on the control board and perform a continuity test.
