Air Conditioner

FCU / Indoor Unit is the equipment that is installed inside your house premises such as the bedroom, living room and dining room.

CU / Outdoor Unit is the equipment that is usually installed outside of your house building.

Compressor is a part located inside the Condenser Unit / Outdoor Unit.

Refrigerant refers to the gas substance, a cooling agent, used in the refrigeration cycle, in the coils of the air conditioning unit.

1. Before purchasing an air conditioner, check the Energy Label and the number of ticks to understand how energy-efficient the unit is. The more ticks the unit has, the more cost savings you have. For more information, visit the Singapore National Environment Agency (NEA) website.

2. Select the air conditioner capacity based on the recommendation by our authorised dealers such as performing a heat load calculation. Find the nearest authorised dealer here.

3. To find out whether the installation carried out by the installer is in accordance with the manufacturing instructions, please refer to the installation manual that comes with the unit.

  1. No intermediate joining of wire is allowed.
  2. Insulation thickness must be sized adequately to prevent condensation.
  3. Drainage pipe must also be insulated to prevent condensation.
  4. Restrictions on pipe length and size must be followed strictly according to manufacturing specifications.
  5. The height restriction between the fan coil and the condensing unit must be strictly observed.
  6. If the unit is installed on a bracket, the drainage kit is highly recommended to be installed to prevent condensate water from dripping to lower floors.
  7. The entire air conditioning system must be evacuated thoroughly after installation.
  8. A test run is to be conducted to ensure the fan coil units are in normal working condition.

To calculate your monthly electrical consumption, use the formula below to calculate:

Input (kW) X No. of hours used X No. of days per month X Current Utility Rate

The indoor unit does not produce odour by itself. Generally, the surrounding smell is absorbed into the fan coil unit and discharges out with the airflow. Through air circulation, these small impurity particles in the air attach themselves to the fins or around the drainage areas.

It is also possible that the air conditioner blows out bad-smelling air because of mould and mildew accumulation at the cooling coil and drain pan.

General servicing is required in such cases to eliminate the smell.

The line flow fan may have accumulated too much dirt. It is recommended to carry out general servicing.

This could be due to insufficient refrigerant or lack of service.

If your air conditioner is low on refrigerant, either it was undercharged at installation, or it is leaking. If it is leaking, simply adding refrigerant is not a solution. A pressure test to determine the leak should be conducted, fix the leak and then charge the system with the correct amount of refrigerant.

If it's due to the latter, general cleaning is needed to improve the performance of the air conditioner.

During Cool or Dry operation with the vane angle at Angle 4 or 5 when the compressor's cumulative operation time exceeds 1 hour, the vane angle automatically changes to Angle 1 for dew prevention. This is not a fault but instead it is a safety feature of the unit.

This can be caused by the following:

  • The cooling coil may be choked with impurities.
  • Dirt had clogged up on the line flow fan after a period of time.
  • The filter is dirty.

It is recommended to do general cleaning to improve the performance of the air conditioner. For severe blockages, please engage a professional to perform a thorough cleaning of the unit.

The "Hi/Powerful" fan mode is for rapid cooling and some noise is expected.

It is recommended to reduce the fan speed after the room temperature is achieved to minimise the noise.

It may be due to the following:

  • Screws may not be properly tightened.
  • No rubber pads were placed underneath the outdoor unit.
  • Vibration from the refrigerant pipes may be transmitted along the way.
  • The outdoor unit noise may increase and vary according to the cooling capacity required.

It may be due to the temperature setting on your remote controller being too low.

It may be due to the following:

  • The remote controller may be faulty.
  • The receiver / infrared ray at the indoor unit may be faulty.
  • There is no power supply to the indoor unit.
  • The battery of the remote controller needs replacement.
  • Please check the power supply source whether there is any trip.

It is recommended to replace any of the above items.

  • The connecting wires / refrigerant pipes may be connected incorrectly.
  • LEV coil/valve may be faulty.

This is normally caused by a blockage in the drainage pipe. It is recommended to do general servicing for the air conditioner.

This is normal. During Cool and Dry operations, pipe connecting sections are cooled and causes the moisture from ambient air to condensate. It is recommended to install the recommended drainage kit to prevent water dripping to your neighbour's outdoor unit.

It may be due to the following:

  • The refrigerant gas may be insufficient.
  • The air filters, line flow fan or cooling coil may be dirty.

The latest Starmex series of wall mounted indoor units come with Microparticle Catching Filter that can filter PM2.5 particles.

It is used to improve air quality.

Yes. Flushing of the existing pipes and vacuuming must be performed.

It depends on the set temperature, running hours and the electrical tariff charges. Please refer to the NEA website given below for the individual models' annual energy consumption and cost.

It is recommended to clean quarterly. Replacement is required for wear and tear.

It is used on a rainy day or when the relative humidity is high. The fan occasionally stops to improve the removal of moisture in the environment.

Please refer to the User Manual. The remote controller is of "daily type" setting and is required to program the current time first, followed by the start and stop button of the timer.

This shows that the room temperature has reached or is close to the remote controller setting temperature.

Yes, please bring your remote controller to us for modification.

  • The temperature will only be shown in the "Cool" mode setting.
  • The remote controller may be faulty. It is recommended to purchase your remote controller with us.

Please switch to "Hi" fan speed for faster cooling.

No, the performance of the air conditioning system will not be guaranteed if aluminium piping is used. It is highly recommended to use copper piping.

Rust is not covered under our Warranty Terms. We do not provide paint works for the rust.

Due to the compact high efficiency design of the heat exchanger, the use of wall-mounted fan coil unit is not recommended. Only ceiling concealed or suspended units are recommended for such installation.

They are blinking continuously as the safety switch located on the left of the louvers is not properly locked in. It acts as a safety device and does not mean that your unit is faulty. Ensure that the safety switch is properly secured in position, and it will stop blinking.

The life span will be shortened if the unit is not serviced periodically. This is because the build-up of dirt and contaminant on the cooling coil/blower will affect the unit’s performance and cooling efficiency.

Hence, regular servicing is recommended on a quarterly basis to improve its operational efficiency and cooling performance, minimises water leakage related issues, improve life span and best of all, cost savings on your electrical bills.

While DIY cleaning extends and improves the product’s efficiency and reliability, professional regular maintenance and system checking is necessary, and you should consult the dealers who had installed the product for you on their regular maintenance package that you can sign up.

Generally, the basic scope of servicing includes:

  1. Washing of the front panel, air filter, drain pan and line flow fan
  2. Cleaning the dirt from the cooling coil (heat exchanger)
  3. Vacuuming the drainage pipe thoroughly
  4. Checking the operating condition and temperature of the air conditioning systems

Refrigerator

It is normal. When the refrigerator is operating, noises/sounds may be produced by the moving mechanical parts such as the below examples:

  • Compressor running sound
  • System copper piping vibration sound
  • Air flow sound from the fan motor
  • Expansion/contraction sound - When the refrigerator's door opens, the temperature between ambient and the compartment will cause the structural or the plastic parts to expand/contract, thus, creating the sound.
  • Noise created from ice maker when producing the ice cubes
  • Refrigerant flowing sound

It may be due to the following:

  • Power cord is not plugged in properly.
  • Power socket switch is not turned "ON".
  • Faulty power socket. You may use another power socket switch for testing.
  • Power failure or a tripped circuit breaker.

It may be due to the following:

  • Having too much food inside the refrigerator compartment may block the air flowing to the vegetable compartment.
  • The vegetable compartment door does not close properly, or the door gasket is loose or has gaps in between. Please replace the door gaskets when it is not in good condition.
  • The damper thermostat might be faulty or obstructed by ice formation. You may try to carry out manual de-frosting.

You may increase the air volume by adjusting temperature control of vegetable (this might affect the Refrigerator compartment temperature).

It may be due to the following:

  • The refrigerator compartment door does not close properly, or the door gasket is loose or has gaps in between. Please replace the door gaskets when it is not in a good condition.
  • The damper thermostat might be faulty or obstructed by ice formation. You may try to carry out manual de-frosting.
  • Items are placed too close to the air vents resulting in poor cold air circulation. Do not block off any air vents.

You may increase the air volume by adjusting temperature control of refrigerator (this might affect the vegetable compartment temperature).

You may check whether the Refrigerator door is closed properly, or the door gasket is tight.

It may be due to the following:

  • The door is opened too frequently, or the door is ajar.
  • The unit is installed in a high humidity area.
  • There are gaps found at the gasket.

It is normal to have defrosted water collected in the drain pan. The water will be evaporated by the heat released from the radiator coil / discharge pipe. It is only abnormal when the water overflows.

A refrigerator does not emit a bad smell. It is likely caused by the food stored in the compartment. You may use wraps or food containers to store foods/objects with a strong smell to prevent the smell from circulating into the air vents.

It may be due to the following:

  • The ice maker or the water pump may be faulty.
  • There is no water in the water tank.
  • The water tank is not placed properly
  • The ice-making function is turned off.
  • The refrigerator sensed a false “ice level”. Ensure nothing else other than ice cubes are stored in the ice tray, as it may activate the "ice level" sensor.
  • This happens because refrigerators are built to be airtight. When the fridge door is closed, it pushes the air into the cabinet resulting in the air entering through the air vent and transferring into the other compartment. This will cause the other compartment door to "pop" open. At this time, the bottom door-hinge cater will withhold the door and pull the door close again.
  • Refrigerator should be adjusted slightly inclined towards the back.
  • Check the alignment with the floor level.

There may be too much food obstructing the doors from closing properly.
Ensure the door panel or the pocket are not obstructed by the food parcel or tray itself.

There are anti-condensation pipes built within the cabinet to prevent condensation and for heat dissipation purposes.

There must be a minimum of 20mm gap on the sides and a 100mm gap above the refrigerator.

This may be due to the surrounding environment. It can be commonly found when there’s a construction site nearby or when the occupancy rate of your block is low.
