The conversion
of the fan coil to downflow
requires special

for the condensate
drains on both A-coil and slope
units. The vertical drains have an overflow
hole between
the
primary and secondary
drain holes. This hole is plugged for all
applications
except downflow,
but must be used for do,_vnflow.
During the conversion

NOTES:
1, Airflow based upon dry coil at 230v with factory-approved
filter and electric heater (2 element heater sizes 018 through 036, 3 element heater sizes 042
through 060). Airflow at 208 volts is approximately
10% lower for FA4A models. For FC4D models, airflow at 208 volts is approximately the same as 230
volts because the X13 motor is a constant torque motor. The torque doesn't drop off at the speeds the motor operates,
2. To avoid potential for condensate blowing out of drain pan prior to making drain trap:
-Return static pressure must be less than 0.40 in. wc.

The airflow performance data was developed using fan coils with 10-kW electric heaters (2 elements) in FA4C / FC4D sizes 018 through 036 and FH4C sizes
001 and 002 and 15-kW heaters (3 elements) in FA4C / FC4D sizes 042 through 060 and FH4C sizes 003 and 004. For fan coils with heaters of a different number of elements, the available external static at a given CFM from the curve may be corrected by adding or subtracting available external static pressure as indicated above.
