Compressor Shipping Bolt Removal
Units with InvisiSound™ Ultimate Option
(Model Number Digit 12 = 3)
For chillers built with InvisiSound Ultimate option,
compressor shipping bolts must be removed to assure
minimum noise during operation. Use a 24mm socket to
remove the (3) M15 x 75mm shipping bolts for each
compressor.They are located under compressor
mounting feet. See Figure 15.
Important:
• DO NOT DISCARD SHIPPING BOLTS. Store bolts in the
control panel for future use.
• All shipping bolts MUST be reinstalled prior to
compressor removal or unit move.
Drainage
Locate the unit near a large capacity drain for water vessel
drain-down during shutdown or repair. Evaporators are
provided with drain connections. A vent on top of
evaporator waterbox prevents vacuum by allowing air into
evaporator for complete drainage. All local and national
codes apply.
