loop.
c. Some models may have a factory installed bypass. Follow the instruction
inparagraph“d”belowtoadjustthelowowbypass.
d. Adjusting the Low Flow Bypass:
For Manual Low Flow Bypass Valves:
Start with the bypass completely closed and gradually open the valve
until the low refrigerant pressure digital display reading is in the normal
operating range for the refrigerant type used in the chiller.
For Automatic Low Flow Bypass Valves:
A “T” handle or adjusting stem is located on the top of the valve. Turning
the “T” handle or adjusting stem in the clockwise direction puts more
pressureonthevalve’sspringreducingbypassow.
Turning the “T” handle or adjusting stem counter clockwise puts less
pressureonthespringandincreasesbypassow.
Adjust the “T” handle or adjusting stem until the low pressure digital
display reading is in the normal operating range for the refrigerant type
used in the chiller. If the low pressure digital display reading is below
normal, reduce the pressure on the spring to provide more bypass.
