Condensate Drain; With No Vent Option; With Commercial Room Ventilator; With Energy Recovery Ventilator - Bard I30A1DA Installation Instructions Manual

CONDENSATE DRAIN

There are two condensate drain connections from the
condenser drain pan (compressor area). These are
visible from the rear of the unit. Factory-installed tubing
connects the two drains at a tee connection and then a
single drain hose with a barbed hose connector carries
the condensate to the draining option chosen. Enough
tubing is provided to reach all drain options and can be
cut down in length.
The unit is shipped from the factory with the drain line on
the left-hand side (looking at the rear of the unit). The
tubing can be removed from the drain connections and
flipped for a right-hand drain. See Figure 10.
The drain can be routed directly through the floor or
through the wall. There are also two optional drain
locations in the lower rear back panel. See Figure 10.
The I-TEC design does not require a trap in the
condensate disposal tubing. Check local codes to see if a
"P" trap is required.
For a stand pipe floor drain or through the wall, there
is adequate hose length to reach anything located
behind the unit. The lower rear portion of the cabinet is
recessed approximately 4" allowing room for a "P" trap
to be installed with the cabinet flush with the wall. The
drain line must be able to be removed from the unit if
necessary to remove the unit from the wall.
Access plates are located on the rear of the unit for
servicing the drain trap (see Figure 10). If the drain line
is to be routed through an unconditioned space, it must
be protected from freezing.
The condensate drain line can also be routed back into the
unit through either the right-hand or left-hand optional
drain locations on the rear of the unit. The hole is
covered by insulation on the inside of the unit and will
have to be cut away. Drain holes are located inside the
unit in the bottom of the base about 12" in from the front
on both the left and right side. These holes are covered
with insulation and are not visible. They are located very
close to the side panels and can be found by pressing
down on the insulation. Cut insulation away to expose
the hole. A drain trap can now be installed inside of the
cabinet, and the drain hose routed directly through the
floor.
Once the I-TEC is installed, the rear drains exiting the
condenser section can be easily serviced with removal of
the pre-painted metal sides (lift-off doors, remove four (4)
screws to remove side).
If side access is not available, the drain lines and trap
can be serviced by removing either one of the drain
access panels on the rear of the unit (in the ventilation
package area.) See Figure 10.
