Pressure Switch - Tecmark 4755P

 

This Tecmark pressure switch is commonly found on older Calderra spas & their control systems. These can also be found on Certikin swimming pool boilers and a number of other brands. Replaces other model codes listed below.



Manufacturers Part Number

 

Direct replacement for part numbers: 4755P & 4037P



Dimensions

 

Height - 70mm

Diameter of Switch - 50mm

Diameter of Thread - 9mm


 

Connections

  

This switch has a plastic 1/8" MPT male thread that screws directly into the heater tube assembly. We recommend using some PTFE tape (Plumbers Teflon Tape) to seal the switch against the tube, electrical connection via 2 x male spade terminals.


 

Additional Information


Before replacing this switch on your spa be sure that there is not a low flow problem on your spa such as dirty filters, low water level or a blockage in the pipework.


 

All pressure switches are designed to detect poor flow or insufficient water across the heater element, they do this by detecting water back pressure inside the heater assembly. If not enough pressure is detected the heater will not be switched on and be saved from dry firing (burning out).
