Startup Checklists
Table 64. Startup checklist — 24-89 ton evaporative cooling
Access/Egress
Initial Site Inspection
Unit exterior inspected for damage (dents, bends, missing panels, doors work properly)
Unit clearances adequate to avoid air recirculation etc.
Verify crankcase heaters are working and on for 8 hours prior to unit start (may require 480V availability)
Wear electrical PPE
Lockout tag out unit
Verify unit interior is free from debris/obstructions etc.
All unit drain lines and traps installed properly
Remove electrical access panel fastened by (9) bolt/screws or open access doors
Verify unit is grounded. Confirm a ground wire is coming from power source.
Verify main power feed wire gauge is properly size for current load
Verify all wiring connections are tight
Verify all field control wiring for CV or VAV controls complete
Verify all automation and remote controls installed/wired
Verify shipping hardware and plastic covers for compressors has been removed
Verify hold down bolts and channels from fan sections removed
Fan section spring isolators checked/adjusted (approx ¼" gap above shipping block)
Verify damper linkages are tight/adjusted and tip seals are in good condition
Verify compressor oil levels at proper level (½ -¾ high in glass)
Compressor discharge service valves, oil valves and liquid lines valves open/back seated
All fan belts tensioned, bearings greased and sheaves in alignment
Verify supply and exhaust fan pulley bolts are tight
Verify fans rotate freely
Verify refrigerant charge on each circuit
Remove lock out tag out
Wear electrical PPE
Verify correct voltage supplied to unit and electric heaters (see IOM for assistance)
Verify incoming voltage phase balanced
Verify all fans rotate in proper direction
Verify fan amperages within nameplate specs (Please document on log sheet)
Unit Configuration and Setup
Verify model number in the UCM configuration matches unit model number on name plate
Configure unit using IOM and critical control parameters listed in
Evaporative Condenser (Digit 27)
Verify condenser fan shipping bracket has been removed from above mist eliminators in evaporative condenser module
Verify all water and drain connections are complete
Verify inlet water pressure is between 35-60 psig, dynamic pressure (measured with valve open) for min. flow rate of 30 GPM
Verify drain valve function is set to "drain during power loss" or "hold during power loss" per job specification
Verify that the sump fills to a level within the slot on the max float bracket as shown in
Verify water treatment system has been installed/approved - discontinue startup if proof of active water treatment does not exist
Verify conductivity controller calibration has been documented and min and max setpoints have been setup
