Chemical Hazards
The Polycold Cryochiller is supplied with two Overpressure Relief Valves. In the unlikely event that the
relief valves release refrigerant gas, the gas must vent to atmosphere in a well vented area that meets
the minimum room size requirements as specified in ASHRAE-15 and EN-378.
Asphyxiation Hazard
The blend of refrigerant used in the Polycold Cryochiller is non
flammable and non toxic. However, as with any gas, asphyxiation
could occur if concentrated refrigerant gas is inhaled which may
cause death or serious injury.
• Service the Polycold Cryochiller in a well ventilated area as
specified by ASHRAE-15 and EN-378.
Chemical Hazard
Opening the refrigerant circuit or changing valve settings without
following the instructions in this manual could result in release of
refrigerant gas which is considered a green house gas.
• Avoid releasing refrigerant gas to the atmosphere.
• Keep the gas line couplings aligned when making or breaking
coupling connections to prevent leaks due to a sharp bends.
• Review this manual before performing any procedure including
routine operation.
NOTICE
United States and other federal laws require a certified refrigeration technician
(Type 2, High Pressure) perform any procedure that could release refrigerant to
the atmosphere.
This includes:
• Installing the Polycold Cryochiller
• Inspecting procedures
• Disconnecting the refrigerant lines
• Troubleshooting procedures
• Repairing
• Disposing of the unit or charged components
