Veelgestelde vragen - CCH50H4C Maxicool

Hoe installeer ik de Maxicool CCH50H4C airconditioner?

Plaats het apparaat op een vlakke ondergrond dicht bij een raam of deur. Sluit de luchtafvoerslang aan op de meegeleverde raamafdichting en steek de stekker in het stopcontact. Zorg dat de slang niet geknikt is.

Hoe vaak moet ik het filter reinigen?

Reinig het wasbare stoffilter elke 2 weken met lauw water en een milde zeep. Laat het volledig drogen voordat u het terugplaatst. Een vuil filter vermindert de koelprestaties.

Wat moet ik doen als de airco water lekt?

Controleer of de waterafvoerslang niet verstopt is of geknikt. Zet het apparaat waterpas. Bij vriezend weer kan de interne waterbak overlopen; leeg deze dan handmatig via de aftapdop.

Kan de airconditioner ook verwarmen?

Nee, de Maxicool CCH50H4C is alleen geschikt voor koelen, ontvochtigen en ventileren. Er is geen warmtepompfunctie aanwezig.

Waarom koelt het apparaat niet goed?

Controleer of het filter schoon is en de luchtafvoerslang correct is aangesloten. Zorg dat ramen en deuren gesloten zijn. De buitentemperatuur mag niet te hoog zijn (max. 43°C).

Hoe kan ik de temperatuur instellen?

Gebruik de afstandsbediening of het bedieningspaneel om de gewenste temperatuur in te stellen (16-32°C). Er zijn ook standen zoals Turbo, Slaap en Eco.

Wat is het stroomverbruik per uur?

Het gemiddelde verbruik is ongeveer 1,2 kWh per uur, afhankelijk van de ingestelde temperatuur en de buitentemperatuur. Het apparaat heeft energielabel A+.

Kan ik het apparaat zonder afvoerslang gebruiken?

Nee, de luchtafvoerslang is noodzakelijk om warme lucht naar buiten te blazen. Gebruik zonder slang leidt tot een slechte koeling en oververhitting.

Wat moet ik doen als het display een foutcode toont?

Raadpleeg de handleiding voor de betekenis van de foutcode. Veelvoorkomende codes: E1 (sensorprobleem), E2 (oververhitting), E3 (waterbak vol). Neem contact op met de klantenservice voor reparatie.

Hoe kan ik de airconditioner winterklaar maken?

Reinig en droog het filter en de condensor. Tap al het water uit de bak. Berg het apparaat op een droge, vorstvrije plaats op. Verwijder de batterijen uit de afstandsbediening.

HOW TO GET THE OPTIMIZED PERFORMANCES

Clean the air filter screen from time to time

Blocking of the air filter screen will reduce the airflow volume and affect the cooling or heating effects. If the air filter screen is too dirty, it might lead to faulty operation of the air conditioner. Please clean the air filter screen at least once every two weeks.

If the air conditioner has not been in use for a long time, please clean the air filter screen before you put it into operation.

Cleaning steps:

1. Remove the air filter screen;
2. Use a vacuum cleaner to clean it or use clean water to flush it.
3. After the screen is flushed clean with water, place it in a cool and dry place until it is dried. Do not heat it dry with fire.

Set the room temperature at a comfortable setting.

During cooling operation, the temperature difference of 5^ C between the room temperature and the outdoor ambient temperature is most comfortable. Excessively low setting of room temperature might do harm to your health and consume lots of power energy. During the cooling operation, raising the room temperature by 1^ C will save about 10 % of power consumption for you.

Try to avoid the heat sources as much as you can.

When the units are in the cooling mode, you should pull the window curtains to shed off the direct exposure of sunlight. The doors and windows of the room must be closed, and frequent opening of the door should be avoided.

Keep the room air exchanged from time to time.

Open the windows of the room periodically to let the fresh air in, which makes the room air more comfortable and healthy.

Self diagnosis function

Our company provides the end-users with thoughtful services by installing various diagnostic systems to indicate the following irregular performances.

The following phenomena are not faulty operational performances:

● Sometimes the air sent out from the air conditioner may smell some odd odors. This is due to the cigarette smoke, the cosmetic smell, the odors of walls or furniture pieces in the room that are stained on the air conditioner.

Flashing of red lights	Performance faults
1 time/1 seconds	Faulty coils
1 time/3 seconds	Cold air protection(normal function)
2 times/4 seconds	Room temperature sensor faults
3 times/5 seconds	Faulty coils
4 times/6 second	Outdoor unit (overflow, electric network voltage faults)
5 times/7 seconds	Frost resistance protection(normal function)
7 times/9 seconds	Abormity of out feed back
8 times/10 seconds	Overheating protection
9 times/11 seconds	Water pump faults

• During the operation or when the machine is stopped, some "ZZZ..." sound may be heard. This is because the refrigerant inside the air conditioner is still flowing.
• When the cooling or heating operation is started or stopped, some "patting" sound may be heard. This is because some parts of the surface boards are expanded due to changes of temperature, which results in the friction of these parts. This is not a performance fault.

Installation and maintenance spaces for the outdoor unit

When a single unit is installed:

(unit: mm)

(1) When there are blocking objects above

In the case that the spaces are left as shown in the figure, it does not matter much whether there are blocking objects in the rear.

(2) When the front (air outlet) is open

In the case that the spaces are left as shown in the figure, it does not matter much whether there are blocking objects on three sides of the unit (with the top left open).

(3) When there are blocking objects only in front

In this case, the rear and the two flanks as well as the top should be left open.

(4) When there are blocking objects in the front and rear

Do not use the following space specifications. Please refer to Item (5)

Make sure of the maintenance space in the front as shown below.

(5) When there are blocking objects only in the front and rear

In the places where there are blocking objects and air flow is poor, the height and width of the blocking object must be within the following specification in order to prevent from the risk of short circuits for the outdoor unit air inlet and outlet (If the front and rear can meet this condition, there will be no particular limitations for the two flank sides).

Width of blocking objects: No larger than 1.5 times of the width of the outdoor unit

Height of blocking objects: No larger than 1 time of the height of the outdoor unit

(6) When there are blocking objects all round the unit

Although the top is left open, the installation still cannot be done in this case.

When more than one unit is to be installed: (unit: mm)

(1) When the units are installed in parallel (please remove the screws on the side of the supplementary piping cover)

Note: The topside must be open for such kind of installation.

When the installation is made on the rooftop or other places subject to strong wind:

When the outdoor unit is to be installed on the rooftop or at the places where there are no other buildings around, it is required to avoid the strong wind from blowing directly into the air outlet of the outdoor unit so as to prevent the negative impacts on cooling or heating performances due to insufficient airflow of the outdoor unit heat exchanger and to prevent from faulty performances.

When there are walls in the vicinity, the air outlet should face the wall and keep a space of 500mm from the wall.

When the air outlet is affected by the strong wind, the installation position should be changed so as to make the air outlet at a straight angle from the wind direction.

Piping line construction for refrigerant pipe

1) Indoor units

Sequence of connections of supplementary pipes

1. Keep the gas and liquid valves of the outdoor unit in its original closed state (the ex-factory state); remove the screw nuts of the indoor pipe and outdoor pipe, dust-proof cap and stoppers of the supplementary pipes; make the connections of the bell-mouths quickly (to avoid dust or moisture or other objects from entering the pipes, which might result in faulty operations of the units).

2. When the connection of pipes is made, please use two wrenches. The related torque forces are shown.

3. Do the bell-mouth connections one by one until all the refrigerant pipes are well connected.
4. Use a small amount of the refrigerant in the main unit to do the evacuation of the pipes.
   ● After the pipes are connected, you must do the leakage checks by soap water or a special detective device to see if there is any leakage.

CAUSTION: the discharged way should be done according to the refrigerant character. The refrigerant is shown on the nameplate.

R22: When the pipe length is within 5 meters, use the refrigerant inside the unit to discharge the air in the pipes, When the pipe length is above 5 meters, use pump vacuum or refrigerant bottle.

R407C/R410A: Use pump vacuum(special for R407C/R410A) or refrigerant bottle to discharge.

Please have the professional technicians to do the installation for you.

1. After the above operations are completed, use a S4 inner hexagonal wrench to turn open the gas and liquid valves of the outdoor unit, which makes the refrigeration loops of the indoor and outdoor unit fully connected.
2. The bending of the supplementary pipes should not exceed 90 degrees, and the bending is not allowed to occur more than three times.
