3.5 Pipe connection
1. Must be connected to air supply and return pipe of more than 1m, also can effectively avoid short circuit of
supplying and returning.
2. The equivalent static pressure of the longest pipe length should be less than or equal to 90Pa to ensure the
normal operation of the unit.
3. Install a downwardly sloping pipe to prevent rain from entering and to provide heat to the pipes and connections
to prevent condensation.
4. Static pressure dialing of electronic control should be selected according to the static pressure of the installed
pipeline.
3.6 Position and installation of outlet pipe
1. Drainage sometimes gets ice, so avoid draining where people use it often.
2. When installing this unit, the outlet section of the drain pipe should be lower than the opposite
side(>25mm/<30mm) to avoid poor drainage.
3. As shown in the figure below, the siphon must be connected and special care must be taken when connecting
the unit.
4. The inner diameter of the prepared drain pipe should be greater than 25mm, and the drain pipe should be bent
downwards, and the slope should be greater than 2%.
5. Check to make sure the drain is smooth. Pour some water into the drain pan to make sure the water does not
stay on the drain pan.
6. Check drain fittings regularly (annually) to avoid water leakage.
