IARC has also classified these fibrous materials as group 2A 0 carcinogens when they have undergone long term exposure to temperatures greater than 1800 F. A group 2A agent is considered to have the probability of being carcinogenic to humans. For these reasons, we suggest the use of a 3M 9900, 3M 8710, or equivalent mask when working with any ceramic fibe

All installations and services must be performed by qualified service personnel. EXAMPLE: Heating output of furnace is 100,000 x 1.4 100 = 1400 CFM. Air conditioning installed is 4 tons x 400 CFM = 1600 CFM or 48,000 BTU's. NOTE: The duct system must be sized for the larger CFM requirement for cooling. If only 3 tons 36,000 BTU's of cooling x 400 CFM = 1200 CFM was installed, the duct would have to be sized for the 1400 CFM heating requirement. To insure obtaining the necessary air hand
