Frequently asked questions

Refer to the electrical diagram in the manual of your SICCOM product (manuals available HERE)

Disconnect all power supply during the installation.

We strongly recommend, if the product is equipped with one, to install the alarm (NC contact).

  • Electrical connection without alarm: Take the power cable to the terminal block of the air conditioning indoor unit. Connect the "phase” wire of the pump to the "phase” terminal of the terminal block, the "neutral” wire of the pump to the "neutral” terminal of the terminal block, and the "ground” wire (if applicable) of the pump to the "ground”

  • Electrical connection with alarm: Take the power and alarm cables to the terminal block of the air conditioning indoor unit.

Connect together (using a Wago-type terminal):
– the "phase” wire from the outdoor unit
– the "phase” wire from the pump supply
– the "common” wire from the pump alarm

Connect the "neutral” wire from the pump supply to the "neutral” terminal of the indoor unit.

Connect the "NC” wire of the pump alarm to the "phase” terminal of the indoor power supply

Connect the "ground” wire (if applicable) of the pump power supply to the "ground” terminal of the indoor unit

Cut and insulate the unused "NO” wire (if applicable).

If the pump does not drain water and makes a loud noise (dry pumping):

  1. Check that the suction height between the detection block and the pump is not too high (consult the product documentation by clicking HERE)
  2. Check that the suction tube is not pinched, twisted, or clogged
  3. Check that the filter in the sensor block is not clogged
  4. Check that there is no air intake on the suction tube connections (connection with the detection block and connection with the pump): Is the tube suitable (consult the diameter recommended in the manual)? Are the clamps properly installed on the connections?
  5. Check that the pump has been installed in the right direction (see the arrow indicating the discharge direction on the pump block)

This is completely normal. When the pump is first started, it sucks in air (dry pumping) for a few seconds while the condensate water is being pumped. However, this noise should not occur again afterwards. If it does, please refer to FAQ n°4.

To help solve the problem, we invite you to identify the type of noise made by your pump:

 

Noise A (dry pumping at the beginning of each pump cycle) :

  1. Check that there is no negative discharge.
    (Negative discharge is a siphoning of the water column. It causes the pump to run dry at the start of each pump cycle. This leads to high noise and premature wear of the pump).

    It occurs when the end of the discharge pipe is at a lower level than the pump block (see figure 1).
    There are two solutions:
    ⇒ Solution 1 : Install your discharge tube so that its end is at a higher level than the pump block. If necessary, connect it to a larger diameter pipe (see figure 2).
    ⇒ Solution 2 : Install the SICCOM Stop Siphoning (see figure 3)
  2. Check that there is no air intake on the suction tube connections (connection with the detection block and connection with the pump): Is the tube suitable (consult the diameter recommended in the manual)? Are the clamps properly installed on the connections?

 

Noise B (vibrations against plastic):

Check that the pump and the discharge tube are not in contact with a potentially vibrating plastic element (e.g. a trunking or an air conditioner plastic). It is important that the vibrations of the pump do not propagate to adjacent elements.

 

Noise C (vibrations against metal):

Check that the pump and discharge tube are not in contact with a potentially vibrating metal element (e.g. metal framing or sheet metal). It is important that the vibrations of the pump do not propagate to adjacent elements.

  1. Check that dirt is not blocking the float in the upper position (in the detection block)
  2. Check that the pump flow rate is adapted to the air conditioner capacity
  3. Check that the suction tube and the discharge tube are not pinched, twisted, or clogged
  1. Check the electrical connections (see FAQ n°1)
  2. Check the correct connection of the connectors (if applicable)
  3. Check that the float (in the detection block) is positioned in the right direction and not inverted (consult the manual of your product by clicking HERE)

  4. Check that the pump is not overheated (pump block is very hot)
    The thermal protection is activated due to an installation fault or pump malfunction. Wait for cooling down (approx. 20 minutes). Check that the pump is suitable for the air conditioner. If necessary, change the pump.
  1. Check that the detection block is well fixed in the horizontal position

  2. Check that the pump flow rate is adapted to the air conditioner capacity
  3. Check that there is no air intake on the suction tube connections (connection with the detection block and connection with the pump): Is the tube suitable (consult the diameter recommended in the manual)? Are the clamps properly installed on the connections?
  4. If the product is older than 6 years (see date code "week/year” on the pump), your pump may be at the end of its life (depending on the conditions of use). A replacement should be planned.
