Häufig gestellte Fragen - MCA30HRN1 MIDEA

Wie installiere ich die Klimaanlage Midea MCA30HRN1 richtig?

Stellen Sie das Gerät auf eine ebene Fläche in der Nähe eines Fensters. Befestigen Sie den Abluftschlauch an der Rückseite und führen Sie ihn nach draußen. Dichten Sie das Fenster mit der mitgelieferten Abdichtung ab, um warme Luft fernzuhalten.

Warum kühlt die Klimaanlage nicht richtig?

Überprüfen Sie, ob der Abluftschlauch nicht geknickt oder blockiert ist. Reinigen Sie den Luftfilter. Stellen Sie sicher, dass alle Fenster und Türen geschlossen sind. Der Raum sollte nicht zu groß für die Kühlleistung sein.

Wie reinige ich den Filter der Midea MCA30HRN1?

Schalten Sie das Gerät aus und ziehen Sie den Netzstecker. Entfernen Sie den Filter an der Rückseite. Waschen Sie ihn mit lauwarmem Wasser und milder Seife. Lassen Sie ihn vollständig trocknen, bevor Sie ihn wieder einsetzen.

Kann ich die Klimaanlage auch nur als Ventilator nutzen?

Ja, drücken Sie die MODE-Taste auf der Fernbedienung oder am Gerät, bis das Ventilator-Symbol angezeigt wird. Die Kühlfunktion ist dann deaktiviert.

Was bedeuten die Fehlercodes auf dem Display?

Ein Blinkcode wie E1 deutet auf einen Sensorfehler hin. E2 bedeutet Überhitzung. Schlagen Sie in der Bedienungsanleitung nach oder kontaktieren Sie den Kundendienst.

Wie oft muss ich das Kondenswasser leeren?

Der Wassertank fasst 1,5 Liter. Bei hoher Luftfeuchtigkeit kann er täglich voll sein. Das Gerät piept, wenn der Tank voll ist. Leeren Sie ihn dann über den Ablaufhahn an der Unterseite.

Kann ich die Klimaanlage ohne Abluftschlauch betreiben?

Nein, der Abluftschlauch ist notwendig, um die warme Abluft nach draußen zu leiten. Ohne ihn kühlt das Gerät nicht und kann Schaden nehmen.

Welche Raumgröße kann die Midea MCA30HRN1 kühlen?

Die Kühlleistung von 12.000 BTU/h ist für Räume bis zu etwa 30 m² geeignet. Bei hoher Sonneneinstrahlung oder schlechter Isolierung kann die Effizienz sinken.

Warum läuft die Klimaanlage nach dem Ausschalten noch nach?

Das ist normal: Der Lüfter läuft noch kurz, um die Restfeuchtigkeit im Gerät zu trocknen und Schimmelbildung zu verhindern. Nach einigen Minuten schaltet er sich automatisch aus.

INSULATION

Be sure to with insulating materials cover all the exposed parts of the flare pipe joints and refrigerator-

• ant pipe on the liquid-side and the gas-side. Ensure that there is no gap between them.
• Incomplete insulation may cause water condensation.

CONNECT THE DRAIN PIPE

1. Install the drainpipe of the indoor unit

• You can use a polyethylene tube as the drainpipe (out-dia.37-39mm, in-dia.32mm). It could be bought at local market or from your dealer.
• Set the mouth of the drainpipe onto the root of the body's pump-pipe, and clip the drainpipe and the out-let pipe sheath (fittings) together firmly with the out-let pipe clasp (fitting).

CAUTIONS: Use your strength carefully to prevent the pump-pipe from breaking.

- The body's pump pipe and the drainpipe (especially the indoor part) should be covered evenly with the out-let pipe sheath (fittings) and be bound tightly with the constrictor to prevent condensation caused by entered air.

- To prevent water from flowing backwards into the air conditioner while the air conditioner stops, please lean the drainpipe down toward outdoor (outlet-side) at a degree of over 1/50. And please avoid any bulge or water deposit.( Refer to Chart 28.a)

- Do not drag the drainpipe violently when connecting to prevent the body from being pulled. Meanwhile, one support-point should be set every 1\~1.5m to prevent the drainpipe from yielding (Refer to Chart 28.b). Or you can tie the drainpipe with the connecting pipe to fix it.(Refer to Chart 28.c)

- In the case of prolonged drainpipe, you had better tighten its indoor part with a protection tube to prevent it from loosing.

- If the outlet of the drainpipe is higher than the body's pump joint, the pipe should be arranged as vertically as possible. And the lift distance must be less than 200mm, otherwise the water will overflow when the air conditioner stops.( Refer to Chart 29)

- The end of the drainpipe should be over 50mm higher than the ground or the bottom of the drainage chute, and do not immerse it in water. If you discharge the water directly into sewage, be sure to make a U-form aquaseal by bending the pipe up to prevent the smelly gas entering the house through the drain pipe.
