Fan Coil <br /> Gentlemen: <br /> To fvrther our request for a variance of the electrical codes for the <br /> subject UL listed units, the following is a list of reasons why we feel a <br /> variance should be granted. <br /> 1. The fan coil units used on sUbject job are UL listed and UL labeled <br /> for 208/290/1/60 as described in the attachAd brochure (also see the <br /> attached copy of the UL card listing) . The state codes require a UL <br /> label or nationally recognized testing laboratory. <br /> 2. The building HVAC design is such that it will maximize on energy con- <br /> ' servation. To do so _equires the addition of safety, pressure electric <br /> (P.E.) switches to stage the fan and electric heat, when required. <br /> 3. The units will basically operate at 290/1/60 voltage although 277/1/60 <br /> voltage is being supplied to the unit, which requires the use of a <br /> choker coil. <br /> 4. For logical and economic reasons the choker coil (277/1/240) and the <br /> P.E. switch were consolidated on the fan coil chassis. These devices <br /> were installed on the fan coil units at the manufacturer's factory, to <br /> insure �afe and proper installation per UL standards. <br /> 5. The choker coil, P.E. switch and safety devices, consolidated on the <br /> fan coil chassis are UL approved devices for this type of application <br /> (see attached letter from Tempco dated 8/9/80) . <br /> ,�J�'(R(1�CKg Gc 7Ms�Kdbtl4l'�MtatllttlQL G�x�4�[dl 4Kd �/Grll�QlGY j S�{d�LMtd <br />
