833 uPC hot gas temp. Hot gas temperature is
outside the allowable range. Difference between the
low pressure and high-
pressure side is too large.
Superheating too high.
Refrigerant quantity too
small. Clean the condenser
and filter. Check the
function of the fan.
Check the cooling
water circuit. Install the
cover panels. Press the
Reset button and
acknowledge at the
display.
834 uPC press. diff. min The pressure difference is
smaller than that needed
for lubrication of the
compressor. Compressor does not
develop any pressure Contact KKT chillers
