![]() ![]() The conversion of the fan coil to downflow requires special procedures for the condensate drains on both A–coil and slope units. Use fireproof resilient gasket, 1/8 to 1/4–in (3 to 6 mm) thick, between duct, unit, and floor.įailure to follow this caution may result in product or property damage. In this application, field conversion of the evaporator is required using accessory downflow kit along with an accessory base kit. 1 - Slope Coil Unit in Upflow Application 1.) A field–supplied bottom closure is required.įig. Side return is a field option on slope coil models. If return air is to be ducted through a floor, set unit on floor over opening and use 1/8 to 1/4–in (3 to 6 mm) thick fireproof resilient gasket between duct, unit, and floor. ![]() Consult local codes for additional restrictions or precautions. Some localities may allow as an alternative, the running of a separate, secondary condensate line. IMPORTANT: When unit is installed over a finished ceiling and/or living area, building codes may require a field–supplied secondary condensate pan to be installed under the entire unit. Allow space for wiring, piping, and servicing unit. Unit can stand or lie on floor, or hang from ceiling or wall. Check rating plate to be sure unit matches job specifications. Locate unit rating plate which contains proper installation information. File claim with shipping company if shipment is damaged or incomplete. Inspect equipment for damage prior to installation. Remove carton taking care not to damage unit. See Product Data literature for all available accessory kits. Factory– authorized, field - installed electric heater packages are available in sizes 5 through 30kW. These units are available for systems of 18,000 through 60,000 BTUh nominal cooling capacity. These units require a field supplied air filter, and are designed specifically for R–410A refrigerant air conditioners and heat pumps as shipped. These units have be designed for upflow, downflow (kit required), and horizontal orientations, including manufactured and mobile home applications. All FB4C fan coils use a multi–tap ECM motor for efficiency. These units are designed to meet the low air leak requirements currently in effect.įB4CNF(018–048) uses a refrigerant piston metering device. Use care and wear appropriate protective clothing and gloves when handling parts.įB4C models are R–410A Fan Coils designed for installation flexibility. Sheet metal parts may have sharp edges or burrs. Lock out and tag switch with a suitable warning label.įailure to follow this caution may result in personal injury. Turn off accessory heater power if applicable. There may be more than one disconnect switch. Failure to follow this warning could result in personal injury or death.īefore installing or servicing unit, always turn off all power to unit. ![]()
