3.4.1WALLMOUNT STARTUP CHECKLIST

Operation		Procedure
Bypassing TCS22		Disconnect power to the TCS22. Unplug the plug in connectors J4 and
Controller		J5 from the controller
Apply power to both		Follow recommended startup procedure in the WallMount installation
Wall-mounts		instructions. Compressor damage could occur if startup procedures are
		not followed.
Compressor Test		Connect jumper wire on A/C unit low voltage terminals from R to Y
		and observe Compressor operation	(There will be a Time delay
		between the installation of the jumper and the starting of the
		Compressor. The Compressor Time Delay relay will determine the
		time delay period.). After the Compressor starts, the jumper wire can
		be removed.
Blower Test		Connect a jumper wire on A/C unit low voltage terminals R to G and
		observe Blower operation (The Blower will continue to run for One (1)
		minute after the jumper is removed).
Economizer Test		Connect a jumper wire on A/C unit low voltage terminals R to G and
		observe Blower operation. After Blower operation is confirmed, the
		Economizer can be tested. Leave the jumper in place from the previous
		step. Connect a separate jumper on the A/C unit low voltage terminals
		from E to F and observe the Economizer operation (Never connect
		power to terminals E or F).
Heater Test		Connect a jumper wire on A/C unit low voltage terminals R to W1.
		The Heating contactor will engage when the jumper is connected. The
		Blower will also operate while this jumper is in place. To check the
		operation of the Heater, you will have to check the Discharge Air
		temperature of the A/C unit.
Disconnect Power to		Disconnect power to WallMount	air conditioners. Reconnect plug-in
WallMount	Air-	connectors J4 and J5 to the controller. Go to TCS22 Startup Checklist
