    Drake Chiller PACT240D1-T4-ZM

    found this Unit tripped on High Head pressure...reset lock out alarm and watching.. head pressure never goes above 210psi on either circuits. Ambient temp is about 105* and refrigerant is 134A.

    where can i find the high psi limit on this unit... manual..? i thought 134A was about 325psi at 105*.

    210 PSIG would put your saturated condensing temp at 134ish°F. I normally see high pressure cut outs at around 180°F for 134A. Check out the PT chart for 134
