Rotate the fan wheels and energy recovery wheels
by hand and ensure no parts are rubbing.
Check the fan belt drives for proper alignment and
tension.
Filters can load up with dirt during building
construction. Replace any dirty pleated filters and
clean the aluminum mesh filters in the intake hood.
Verify that non-motorized dampers open and close
properly.
Check the tightness of all electrical wiring
connections.
Verify control wire gauge.
Verify diameter seal settings on the energy recovery
wheel.
Verify proper drain trap installation.
Check condensing fans for any damage or
misalignment. Spin the blades and make sure they
don't contact any parts and are free-turning without
any resistance.
Look over the piping system. Inspect for oil at all
tubing connections. Oil typically highlights a leak in
the system.
Inspect all coils within the unit. Fins may get
damaged in transit or during construction. Carefully
straighten fins with a fin comb.
If there is an indirect gas-fired furnace in this unit,
refer to the manual provided with this unit for Pre-
Start-Up information.
This unit contains a crankcase heater for each
compressor which needs power supplied to it
24 hours prior to start-up. If start-up is scheduled
in 24 hours, unlock the disconnect power and
energize unit.
