PIPING
HBC(X), PHBC(X), RHBC(X), CHBC(X):
Installation, Operation, and Maintenance Instructions
7
•
Prior to connecting to the fan coil all external piping must be purged of
debris.
•
All chilled water piping must be insulated to prevent property damage
from condensation.
Condensate drain lines must be installed with adequate slope away from the
unit to assure positive drainage. Since the drain pan is located on the suction
side of the blower, a negative pressure exists at the drain pan. RHBC(X) and
CHBC(X) fan coil units require a minimum trap of 1-1/2 inches provided in the
drain line to assure proper drainage. HBC(X) and PHBC(X) fan coil units may be
located where the return air space is large enough that a negative pressure is
not present, however, a trapped condensate line is recommended in case a
negative condition should occur, the unit would drain properly.
PIPING INSULATION
Installing Contractor
- After the system has been proven leak free, all lines
and valve control packages must be insulated to prevent condensate drippage
or insulated, as specified on the building plans.
NOTE:
Many valve packages will not physically allow all components to fit over an
auxiliary drain pan. It is the installers responsibility to insulate all piping to
ensure adequate condensation prevention.
NOISE
These fan coil units are designed for quiet operation, however, all air
conditioning equipment will transfer some amount of noise to the conditioned
space. This should be taken into consideration when planning the location of
the equipment.
