I-TEC and Q-TEC Products – Condensate Drainage
Condensate drainage for Bard indoor cooling units is a very important part of unit installation. During normal air
conditioning operation, large amounts of condensate water are generated inside the unit as moisture is extracted
from the supply air. This is collected in an evaporator pan and needs to be drained to an external drainage system.
Your new Bard product includes provisions to allow condensate water to exit the unit and fittings will need to be
field supplied to connect the unit drain to the building. Adequate drain sizing needs to be provided to allow proper
drainage for condensate water generation and restriction in drain lines should be avoided. Evaporator drain traps are
not necessary unless required by local codes.
Defrost water for heat pump operation and outdoor water entering the condenser area also needs to be drained out of
the unit. The I-TEC product uses a combined defrost and outdoor water drainage system. The Q-TEC has a combined
defrost and evaporator drain connection unless an optional in-wall drain box is used. Outdoor water exits the
Q-TEC through the wall sleeve. Follow all instructions provided in the unit installation instructions regarding drain
connections and sleeve installation to avoid water leakage inside the building or structure.
