These units are designed to meetthe low air leak requirements currently in effect. Because of this,the units need special attention in the condensate pan and drainconnection area and when brazing tubing. These units are designedspecifically for Puronr refrigerant and must be used only withPuronr refrigerant air conditioners and heat pumps as shipped.These units are available for systems of 18,000 through 60,000Btuh nominal cooling capacity. Factory--authorized, field--installedelectric heater packages are available in sizes 5 through 30kW. SeeProduct Data literature for available accessory kits.HEATER PACKAGESThis unit may or may not be equipped with an electric heaterpackage. For units not equipped with factory--installed heat, afactory--approved, field--installed, UL listed heater package isavailable from your equipment supplier. See unit rating plate for alist of factory--approved heaters. Heaters that are not factoryapproved could cause damage which would not be covered underthe equipment warranty. If fan coil contains a factory--installedheater package, minimum circuit ampacity (MCA) and maximumfuse/breaker may be different than units with a same sizefield--installed accessory heater. The difference is not an error andis due to calculation diferences per UL guidelines.
