search What to do when condensing pressure is too high?

Reason: It may be cooling water not enough; or capacity of cooling tower reduced; or temperature of cool water too high; or cooling capacity too high to increase the load at condenser; or non condensed gas exist; or heat transfer at condensing tube bad for the pollution like furring.
Solution: Check the cool water circuit and adjust it to rated current flow; or check cooling tower and expand throttle etc. to lower (or rise) the temperature of cool water to rated temperature as soon as possible; or get rid of non condensed gas; or clean the tube.

search What to do when evaporating pressure is too low?

Reason: It may be cool water not enough; or cool load low; or failure occurred at throttle orifice; or heat transfer at heat transfer tube of evaporator bad for the pollution like furring; or lack of refrigerant.
Solution: Check the cool water circuit and refill the cool water to rated volume; or check the rated temperature at auto on/off device; or check if expand throttle is blocked; or clean the heat transfer tube; or fill the refrigerant to needed volume.
