WALL MOUNT Products – Condensate and Defrost Drainage
Condensate drainage for air conditioning units
needs to be planned before installation. Your
new Bard WALL MOUNT product includes
provisions to allow condensate water to exit the
bottom of the unit. If condensate water is to be
routed away from the unit, adequate drain sizing
needs to be provided to allow proper drainage
for condensate water generation. During normal
air conditioning operation, large amounts of
condensate water is generated inside the unit as
moisture is extracted from the supply air. This
is collected in an evaporator pan and drained
to either a drainage system (indoor products)
or outside the unit cabinet (outdoor products).
Evaporator drain traps are not necessary for any
of our wall mounted outdoor products, and the
use of "standing water" U-shaped traps may be
prone to freezing in certain climate zones.
Defrost water drainage from heat pump units
needs to be planned before installation. During
seasons requiring heating operation, the unit
will need to warm the condenser coil to remove
frost build-up (defrost). Outdoor heat pump
products include holes in the unit base under
the condenser coil for proper water drainage
when in the heating defrost cycle. Avoid placing
the unit on a pad or blocking the base drainage
holes under the condenser coil without proper
allowances (6" recommended) for water drainage
due to damage caused by freezing conditions.
Without proper drainage, defrost water may
freeze causing ice build up and damage the
lower portion of the condenser coil.
Defrost Water Drainage:
Holes are provided in the front of the unit base for heat
pump condensate water drainage.
Defrost Water Drainage:
6" clearance is recommended under WALL MOUNT Heat
Pump products to allow proper defrost water drainage.
Unit Installation – Wall Mount
Condensate Water Drainage:
Unit condensate water exits the base
of the unit during cooling operation.
