		Setup: The compressor is started. If it is the first compressor start, the
		compressor reliability enhancement logic (CREL) is executed, running a current
		draw test with the additional outputs (if installed) in the following states:
	High Speed
	High Speed	Component	Normal Logic	CREL (3 minutes)
P6-H	Compressor Tests	Component	(10 seconds)	CREL (3 minutes)
	Compressor Tests		(10 seconds)

		SMV	20%	100% (for 3 minutes) then 20%
		SMV	20%	100% (for 3 minutes) then 20%

		Pass/Fail Criteria: Passes if the change in current draw is within the valid
		range.
		Setup: The compressor is started. When ambient temperature is greater than
		60_F, a two minute CREL is executed. If the ambient temperature is less than
		60_F, a three minute CREL is executed. Then a current draw test is done for 10
		seconds with the additional outputs (if installed) in the following states:
	Low Speed

		Setup: The suction modulation valve (SMV) is opened to 100% unless restricted
P6-2	Suction Modulation	by current limit function, and the unit is run for two minutes.
P6-2	Valve (Open)	Pass/Fail Criteria: The supply and return probe temperature reading difference

		is compared to a predetermined value.
		Setup: The compressor suction temperature is measured with the Quench valve

		checked.
		Pass/Fail Criteria: Passes if suction temperature is within the valid range.

		Setup: The heaters are energized. The suction modulation valve is set to 100%,
		and run for one minute. At the end of the one minute run, the supply temperature
		is subtracted from the return temperature and the result is saved (reading 1).The
								3
P6-4	Suction Modulation	SMV is dropped to 60% and run for one minute. At the end of this one minute						3

	Valve (Closed)	run, the supply temperature is again subtracted from the return temperature and
	Valve (Closed)
		the result is saved (reading 2).
		Pass/Fail Criteria: If the difference between reading 1 & 2 is within a
		predetermined range, the test passes. If current limiting occurs, the test passes.

		Requirements: The unit must be equipped with a suction solenoid valve (SSV).
		Current limiting may close SSV. If this happens, the test will automatically pass.
		Setup: The SSV is opened, the suction modulation valve (SMV) is closed. The
		quench valve (if configured) will operate according to normal operating rules. If
P6-5	Suction Solenoid	the return temperature probe is lower than --5.0_C, the test is run for two
P6-5	Valve	minutes, otherwise for one minute. Condenser Pressure Control (CPC) logic is
	Valve
		used for this test if the controller is configured for it.
		Pass/Fail Criteria: If the SSV is closed due to current limiting, the test passes. If
		supply and return probes are invalid, the test fails. If the test is within a
		predetermined range, the test passes. The SSV is closed following this test.
