1. Ensure that the water supply for the Polycold Cryochiller refrigeration unit meets the
specifications in Cooling Water on page 3-6
Optional:
Install pressure gauges on the water lines at the refrigeration unit in order to measure the pressure
drop within the refrigeration unit. This will help you adjust the water flow for optimum operation of
the Polycold Cryochiller. It will also aid you in troubleshooting if there are water cooling problems.
See Figure 4-6
It is also recommended to install two parallel input water lines including valves, water filters, and
flow meters. This allows switching water lines and avoiding equipment shutdown during scheduled
maintenance. See Figure 4-6
NOTICE
If the system is turned on before cooling water has been connected, damage to
the equipment can result.
Verify that cooling water has been connected before turning on power to the unit.
NOTICE
If using rotameter-type flow meters, their inherent restriction may reduce the
actual flow rate delivered to the refrigeration unit.
