1. Brief introduction of Low pressure control JC-206

Low pressure control JC-206 pressure controls is used for either operating or protecting commercial refrigeration or air-conditioning system. They are suitable for R12, R22 and R502 refrigerants and are available copper capiliiary with either flare nut connection or with male flare. Also is widely used in RO water treatment plant. Installed before the RO high pressure water pump, when the feed water pressure is lower than the settled value, the pressure switch will shut off and the machine will be stopped in case of RO high pressure water pump running idle. After malfunction treatment, reset the pressure switch is ok.

3. Fitting method for Low pressure control JC-206

  1.  Avoid sharp bend or kinks in capillary tubing.
  2. When installing to ammonia system, please contact us.
  3. Purge all tubing and lines before connecting pressure controls.
  4. Check that control is not installed on equipment handle a load in excess of electrical rating.
  5. Coil and secure excess capillary length to avoid vibration. Allow some slack in capillary to avoid “violin string” vibration which can cause tubing to break.
  6. Do not allow capillary tubing to rub against metal surface where friction can damage capillary.
  7. Do not turn sealed screws.
  8. Controls are not to be located in area of extreme moisture, dirt or dust, or in a corrosive or or explosive atmosphere. These enviroments can shorten controls life.
