Start-Up Checklist
The following is a comprehensive check list for possible components on your unit.
Exterior, look for damage to housing, doors, handles,
fittings, etc.
Verify proper drain trap installation, if applicable.
Interior, look for damage to fans, exchanger, flue, media,
coils, cells, etc.
Inspect all coils within the unit. Fins may get damaged
in	transit	or	during	construction.	Carefully	straighten	fins	
with	a	fin	comb.
Remove all foreign material from unit.
Check that all ducts, dampers and registers are set.
Check for any loose electrical connections.
Check that all openings and penetrations are sealed.
Check circuit breaker disconnect mechanisms/
mechanical interlocks work properly.
Check fan rotation.
Disconnect and lock-out all power switches.
Rotate each fan wheel by hand to ensure it spins freely.
Verify control wire gauge.
Tighten all fasteners.
Ensure all system components are adjusted to proper
settings (temperature, amperage).
Tighten all set screws and lock collars for each: fans,
bearings, motors, dampers and accessories.
Verify diameter seal settings on the energy recovery
wheel.
Replace any dirty pleated filters and clean any aluminum
mesh filters.

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.
Verify that non-motorized dampers open and close
properly.
Check the fan belt drives for proper alignment and
tension.

Look over the refrigerant piping system. Inspect for
oil	at	all	tubing	connections.	Oil	typically	highlights	a	
leak	in	the	system.
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.
After power has been applied for 24 hours, verify
that	all	crankcase	heaters	are	heating	properly.	Either	
check	the	amp	draw	on	each	heater	or	touch	the	
compressor	near	the	top	to	verify	that	the	heater	is	
warming	the	compressor.	Do	not	touch	the	crankcase	
heater,	it	will	cause	burns.
