	3.4	FIELD QUALITY CONTROL AND TESTING
		A.	To ensure system integrity, do not damage the system or cut heating cable for any reason. Cover heating mat/cable against site damage if there is a delay between product installation and covering installation.
		B.	Perform electrical resistance measurements and record in the mat/cable installation manual as required before, during, and after product installation.
		C.	If LoudMouth monitor device is used, secure before installation begins and remove only after final coverings are finished including grout application.
		D.	Test system briefly after installation for function and integrity but do not place system into full operation until mortars or other coverings as applicable are fully cured per manufacturer specifications.
		E.	Keep records of system products, test results, and photographs for inspection.
	3.5	DEMONSTRATION
