Model FX4D is designed for flexibility and can be used for
upflow, horizontal, or downflow (kit required) and manufactured
and mobile home applications. These units are designed to meet
the low air leak requirements currently in effect. Because of this,
the units need special attention in the condensate pan and drain
connection area and when brazing tubing. These units are designed
specifically for Puronr refrigerant and must be used only with
Puronr refrigerant air conditioners and heat pumps as shipped.
These units are available for systems of 18,000 through 60,000
Btuh nominal cooling capacity. Factory- -authorized, field- -installed
electric heater packages are available in sizes 5 through 30kW. See
Product Data literature for available accessory kits.
HEATER PACKAGES
This unit may or may not be equipped with an electric heater
package. For units not equipped with factory- -installed heat, a
factory- -approved, field- -installed, UL listed heater package is
available from your equipment supplier. See unit rating plate for a
list of factory- -approved heaters. Heaters that are not factory
.
approved could cause damage which would not be covered under
the equipment warranty. If fan coil contains a factory- -installed
heater package, minimum circuit ampacity (MCA) and maximum
fuse/breaker may be different than units with a same size
field- -installed accessory heater. The difference is not an error and
is due to calculation diferences per UL guidelines.
