Units with an “H” (left-hand air supply) in the airflow direction position in the model number
have factory configured evaporator coils for installation in the horizontal position.
Conversion to Horizontal: A vertical upflow evaporator coil may be converted to horizon-
tal by removing the indoor coil and installing horizontal drain pan on coil as shown for right
hand or left hand air supply. Reinstall coil in unit as shown for right or left hand air supply.
See Figures 6 & 7.
Conversion in Horizontal Direction: Evaporator coils configured for horizontal left-hand
supply can be changed to horizontal right-hand supply by removing the indoor coil and
installing the drain pan as shown in Figures 6 & 7 for appropriate air supply direction.
Horizontal Drain Pan Model RXBD-CB: This drain pan is used on all coil models and
fits all unit sizes either right or left hand air supply.
• Install horizontal drain pan as shown for right hand or left hand supply. Drain pan con-
nections must be toward front of coil (header connection end). Install coil assembly
!
CAUTION
HORIZONTAL UNITS MUST BE CONFIGURED FOR RIGHT HAND AIR SUPPLY
OR LEFT HAND AIR SUPPLY. HORIZONTAL DRAIN PAN MUST BE LOCATED
