Model PF4MNA Fan Coils are designed for flexibility and can be
used for upflow, horizontal, or downflow (kit required) and
7
manufactured and mobile home applications. These units are
8
designed to meet the low air leak requirements currently in effect.
9
Because of this, the units need special attention in the condensate
pan and drain connection area and when brazing tubing. These
9
units are designed specifically for R- -410A refrigerant and must be
9
used only with R- -410A refrigerant air conditioners and heat
10
pumps as shipped. These units are available for systems of 18,000
through
60,000

Factory- -authorized, field- -installed electric heater packages are
available in sizes 5 through 30kW. See Product Data literature for
available accessory kits.
HEATER PACKAGES
Factory- -approved, field- -installed, UL listed heater packages are
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.
Step 1 - Check Equipment
Unpack unit and move to final location. Remove carton taking care
not to damage unit. Inspect equipment for damage prior to
installation. File claim with shipping company if shipment is
damaged or incomplete.
Locate unit rating plate which contains proper installation
information. Check rating plate to be sure unit matches job
