CAUTION
Do not use an automotive grade antifreeze. Industrial grade glycols must be used.
Automotive antifreeze contains inhibitors which will cause plating on the copper tubes
within the chiller evaporator. The type and handling of glycol used must be consistent
with local codes.

Altitude Correction Factors
Performance tables are based at sea level. Elevations other than sea level affect the performance of
the unit. The decreased air density will reduce condenser capacity, consequently reducing the unit's
performance. For performance at elevations other than sea level refer to Table 12 or Table 13.
