Notes
1. Water treatment and auxiliary equipment integrated in the cooling system may require additions to the table
above. Contact suppliers for recommended actions and their required frequency.
2. Recommended service intervals are for typical installations. Different environmental conditions may dictate
more frequent servicing.
3. When operating in ambient temperatures below freezing, the unit should be inspected more frequently (see
Cold weather operations in the appropriate Operating and Maintenance Instructions).
4. For units with belt drive, tension on new belts must be readjusted after the first 24 hours of operation and
monthly thereafter.
