Q: What is the purpose of the water collection tray of the COMFEE MPPH07CRN7 air conditioner?

The water collection tray (collector tray located at the bottom of the unit) is designed to accumulate the condensation produced during the operation of the air conditioner in cooling or dehumidification mode. How does the system work? You have two options: With a drainage hose: If you connect a hose to the universal 5/8 inch drainage connector located at the back of the air conditioner, the water flows directly outside or to a fixed drainage system. The tray remains empty at all times. Without a drainage hose: The tray collects the condensation water. When it is full, the air conditioner displays the error code P1 and emits 8 beeping sounds . The unit immediately stops cooling (although the fan continues). Manual draining of the tray To manually drain the tray: Turn off and unplug the unit Move the air conditioner to an appropriate location (sink, bathtub, or outside) Remove the lower drain plug located at the back of the unit Allow the water to drain completely Reinstall the plug securely Tip: If you use the air conditioner regularly, it is recommended to check the tray and drain it regularly to avoid any water stagnation, especially before a prolonged storage period of the unit.

Q: Should I connect the drainage hose to a bucket or to a proper drainage system?

No, you should not use a bucket. The drainage hose must be connected directly to a drainage system (sink, bathroom, wastewater drain). The COMFEE MPPH07CRN7 air conditioner has a 5/8 inch female universal drainage connector at the back of the unit. You need to connect a 3/4 inch drainage hose (to be purchased locally) and position the end of the hose directly above your drainage area. Important points: The hose must slope directly down to the drain without bends or kinks that could obstruct water flow The end of the hose should be directed downward to facilitate gravity drainage Ensure that the hose is securely attached to prevent leaks If you do not have access to a permanent drainage system, you can manually empty the water collection tank when the unit displays the error “P1” (tank full).

Question 1

What is the purpose of the water collection tray of the COMFEE MPPH07CRN7 air conditioner?

Accepted Answer

The water collection tray (collector tray located at the bottom of the unit) is designed to accumulate the condensation produced during the operation of the air conditioner in cooling or dehumidification mode.

How does the system work?

You have two options:

With a drainage hose: If you connect a hose to the universal 5/8 inch drainage connector located at the back of the air conditioner, the water flows directly outside or to a fixed drainage system. The tray remains empty at all times.
Without a drainage hose: The tray collects the condensation water. When it is full, the air conditioner displays the error code P1 and emits 8 beeping sounds. The unit immediately stops cooling (although the fan continues).

Manual draining of the tray

To manually drain the tray:

Turn off and unplug the unit
Move the air conditioner to an appropriate location (sink, bathtub, or outside)
Remove the lower drain plug located at the back of the unit
Allow the water to drain completely
Reinstall the plug securely

Tip: If you use the air conditioner regularly, it is recommended to check the tray and drain it regularly to avoid any water stagnation, especially before a prolonged storage period of the unit.

Question 2

Should the drainage hose be connected at the top or bottom of the COMFEE MPPH07CRN7 air conditioner?

Accepted Answer

The drainage hose connects to the back of the air conditioner, at its lower part.

More specifically, you need to remove the drain cap located at the back of the unit and connect a 3/4 inch hose equipped with a 5/8 inch female universal fitting. The hose should then run directly down to your drainage system (sink, pipe, etc.) without any bends or folds that could obstruct the flow of water.

Important points:

The end of the hose must always point downwards to allow water to flow by gravity
Check for any kinks or pinches along the hose
The hose must be connected to a proper drainage, never to a simple bucket
This connection is optional - without it, the unit displays the error "P1" when the recovery tank is full

Question 3

Should I connect the drainage hose to a bucket or to a proper drainage system?

Accepted Answer

No, you should not use a bucket. The drainage hose must be connected directly to a drainage system (sink, bathroom, wastewater drain).

The COMFEE MPPH07CRN7 air conditioner has a 5/8 inch female universal drainage connector at the back of the unit. You need to connect a 3/4 inch drainage hose (to be purchased locally) and position the end of the hose directly above your drainage area.

Important points:

The hose must slope directly down to the drain without bends or kinks that could obstruct water flow
The end of the hose should be directed downward to facilitate gravity drainage
Ensure that the hose is securely attached to prevent leaks

If you do not have access to a permanent drainage system, you can manually empty the water collection tank when the unit displays the error “P1” (tank full).

Question 4

Do I need to install the water drainage when using the COMFEE air conditioner in cooling mode?

Accepted Answer

Yes, the drainage hose must be installed when in COOL mode.

According to the COMFEE MPPH07CRN7 manual: for cooling mode, the exhaust duct must be connected. Unlike fan or dehumidification modes where you can remove the duct, COOL mode requires this system.

How to install the drainage:

Remove the drain plug located at the back of the unit
Connect a drainage hose (3/4 inch diameter) with a 5/8 inch female universal fitting
Point the end of the hose downward to allow gravity drainage to an appropriate drainage area

Important: During operation, the collection tank fills with condensation water. When it reaches its limit, the display shows "P1" and the unit emits 8 beeps. At this signal, turn off the unit, empty the tank through the bottom plug, and then restart. Regularly emptying the tank prevents mold formation and ensures optimal operation.

Question 5

Where is the drain plug of the COMFEE MPPH09CRN7 air conditioner located and how do I replace it?

Accepted Answer

The lower drain plug is located at the back of the indoor unit of your COMFEE MPPH09CRN7 air conditioner. It allows for draining the condensation water produced in cooling mode.

Features of the plug and drainage:

Compatible with a drainage hose of 3/4 inch (approximately 19 mm) for continuous flow
The hose must not be bent or twisted
The end of the hose must always be positioned lower than the drainage outlet to promote flow
Ensure that no obstruction blocks the passage of water

Important: without the plug:

If the plug is lost, do not use your air conditioner in cooling mode, as the condensation water will not be able to drain. This can cause internal damage or trigger error code P1 (lower tank full).

To replace the plug:

Contact COMFEE customer service or an authorized air conditioning parts dealer, mentioning your device reference: MPPH09CRN7. They will be able to provide you with the appropriate replacement part and install it correctly.

Question 6

Why does the COMFEE MPPH09CRN7 air conditioner produce a lot of water in cooling mode?

Accepted Answer

A significant production of water in cooling mode is quite normal for this type of device and depends on several factors specific to your environment.

Why so much water?

Ambient air humidity - The more humid the air, the more water the air conditioner extracts during the cooling process. This is the natural phenomenon of condensation.
Temperature difference - The greater the gap between the desired temperature and that of your room, the more condensation occurs.
Operating duration - An entire night (8 to 10 hours) of air conditioning naturally generates a large volume of water.

How to manage this water?

The MPPH09CRN7 has a lower tank collection system equipped with a water level sensor. When the tank is full, the device emits 8 beeps and an error code P1 is displayed, stopping the cooling.

Ideal solution: continuous drainage

Connect a 3/4 inch (approximately 19 mm) hose to the rear drain outlet of the device and direct it to a ground drainage (siphon, gutter). Ensure that:

The hose is not bent or twisted (this blocks the flow)
Water flows freely without obstruction
The end of the hose is positioned lower than the outlet to facilitate drainage
The hose is securely fastened to prevent leaks

If you are draining manually: Regularly remove the drain plug at the back and empty the collection tank before prolonged storage to prevent mold formation.

Therefore, abundant water production is quite normal - it simply means that your air conditioner is operating efficiently in a humid environment.

Question 7

How to pair the remote control with the COMFEE MPPH09CRN7 air conditioner?

Accepted Answer

Good news: the remote control for the COMFEE MPPH09CRN7 does not require pairing. It works via direct infrared.

Here is the simple procedure to follow:

Insert the provided batteries into the remote control (if not already in place)
Point the remote control at the indoor unit of your air conditioner
Use it immediately to control the device (change the mode to COOL, FAN, DRY, adjust the temperature, activate the Night/SLEEP mode, etc.)

No synchronization or association is necessary. If the remote control does not respond, check that the batteries are installed correctly and that no obstacles are blocking the infrared receiver of the device.

Question 8

How to manage excessive water production from the COMFEE MPPA09CRN7 air conditioner

Accepted Answer

Your COMFEE MPPA09CRN7 air conditioner collects condensation water in a lower tank. When it is full, the device emits 8 beeps, displays "P1" on the screen, and stops cooling/dehumidification (only the fan continues).

Empty the tank immediately

Turn off the device
Move it to an appropriate location for drainage
Remove the drainage plug located at the back of the unit
Let the water drain completely
Firmly reinstall the plug to prevent leaks
Restart the unit until the P1 symbol disappears

Permanent solution: install continuous drainage

If you often use your air conditioner in dehumidification mode, install a continuous drainage system:

Remove the drainage plug at the back of the unit
Install a drainage connector with a 3/4" hose (to be purchased locally)
Direct the hose without kinks to a drainage area
Position the end of the hose downward to ensure water flow

Maintenance tip: Before winter storage, completely empty the recovery tank to prevent mold formation.

Question 9

My COMFEE MPPF1-12CRN7 air conditioner is restarting in a loop: the screen and indicators light up, the fan starts, then everything turns off after 2 seconds, and the cycle repeats. What is happening?

Accepted Answer

This repeated blinking behavior and cyclic shutdown of the MPPF1-12CRN7 air conditioner indicates an internal problem that the device cannot resolve on its own. The control circuit detects an anomaly and automatically goes into safety shutdown.

Possible Causes

Temperature sensor failure - The sensor from the condenser or evaporator is sending an abnormal signal to the control circuit
Electronic board issue - The control board itself has a malfunction or a faulty connection
Break in connection between display and central unit - The contacts or the cable connecting the display/electronics may be damaged

What you can try first

Completely turn off the device
Unplug the power cable (not just pressing the on/off button)
Wait at least 5 minutes
Plug it back in and turn it on

If the blinking cycle resumes immediately, it is a hardware fault: the device has failed to reset, confirming an electronic issue or sensor failure.

Next Steps

This type of failure is not due to misuse and falls under the COMFEE warranty. Contact COMFEE customer service with:

Your proof of purchase (invoice, order form)
The model reference: MPPF1-12CRN7
A description of the problem (cyclic restart after 2 seconds)

The air conditioner will be repaired or replaced according to warranty conditions.
