water chiller alarm description

Note: The flow alarm is connected to the normally open relay and normally closed relay contacts, requiring operating current less than 5A, working voltage less than 300V.


1. To ensure good heat dissipating, please open the lid to clean the dirt after the chiller is used in long-term.

2. Users in cold area should use noncorrosive antifreeze fluid

  Method of exchanging water in the water tank and the exchanging frequency  

Method of exchanging water in the water tank

Drain the waste water out of the water tank through the drain outlet and fill the clean water into the tank through the filling hole.

  Exchanging Frequency  

The circulating water should be exchanged every 3 months. The quality of the circulating water will directly influence the service life of the laser tube.It is recommended to use purified water or clean distilled water.

  Identify Teyu(S&A) authentic chiller  

All of S&A water chillers are certified with design patent. Counterfeiting is not allowed.

Please recognize S&A logo when you purchase S&A water chillers.
Components carry “S&A” brand logo. It is an important identification distinguishing from counterfeit machine.
