special procedures not covered in the above material can be found in the Reference

VIII. SPARE PARTS ORDERING INFORMATION

Orders for T1000 Systems Spare Parts should be placed with

Phone:  717-509-2200

Please be advised that spare parts should be ordered directly from ITT Engineered 
Valves, as such materials are specially designed for Skotch Trifecta Valve Systems. 
Other replacement parts, although they may be similar in function, will void the FM 
rating. To maintain FM Approval, FM also requires technicians servicing/repairing the 
Skotch Trifecta Valve Systems to be trained by ITT Engineered Valves.
