Room temperature reaches theset point.

Power failure.

Once any of the above conditionsoccurs, the anti-recycle timer willstart preventing the operation ofthe outdoor unit for approximately3 minutes.

Freeze ProtectionThe system is protected against lowindoor coil temperatures. Undercertain conditions, the COOL/DRYLED will blink indicating the protective

function has been activated. There isno need to adjust the system.

Stop the air conditioner at onceif any the following occurs:- The power cord is too hot to be

touched by hand.- The insulation of the power cord is

exposed at any point- The fuse is blown or circuit breaker

trips frequently.- The functions of the switches are

inaccurate.

object into the supply air outlet.In particular, advise small childrennot to insert anything in the grille.

- Do not pour water directly on theair conditioner to clean it. If theair conditioner is operating as wet,grounding may occur, damagingthe unit.

- Adjust the air flow so it does notblow directly on room occupants.

- Do not use flammable sprays nearthe air conditioner because ofdanger of fire.

- Do not use a steel or copper wirein place of fuses.

- Check whether the power supplyis interrupted. Wait until the poweris resupplied and then operate theair conditioner.

Cooling is insufficient:- Check whether the air filter is

clogged. Clean it.- Check whether the thermostat

setting is too high. Set thethermostat to lower temperature.

- Check whether windows or doorsare opened. If opened, close them.

- Check whether there are sourcesof heat in the room, cooling is lesseffective.

- Check whether the return air grilleor the supply air grille on theindoor unit and outdoor unitare blocked. If they are blocked,remove obstacles to permit air

passage properly.- Check whether the fan speed is setat low. Set the fan switch fromLOW to MED or HIGH

Heating is insufficient:- Check to see if the air filters are

clogged with dust or debris. Cleanthe air filters.

- Check to see if the thermostatsetting is too low. Set thethermostat a higher temperature.

- Check to see if windows or doorsare open. If they are open, close.

- Check to see if the return air grilleor the supply air grille on theindoor unit are blocked. If they areblocked, remove obstacles topermit air passage properly.
