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 of your choice.
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 as you look at the rear of the unit.
The tubing can be removed from the drain connections
and flipped for a right-hand drain. See Figure 8.
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 8.
The I-TEC design does not require a trap in the
condensate disposal tubing. Check your 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 needed location behind the
unit. The lower rear portion of the cabinet is recessed
approximately 4 inches allowing room for a “P” trap (if
required) to be installed with the cabinet flush with the wall.
Keep in mind, 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 8.
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. Located inside the unit,
about 12 inches in from the front on both the left and
right side are drain holes in the bottom of the base.
These holes are covered with insulation and are not
visible from inside vent option area. They are located
very close to the side panels and can be found by
pressing down on the insulation or looking at back of
vent option area (See Figure 8). 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 ventialtion
package area.) See Figure 8.
After drain installation is complete, drain area must
be insulated for sound purposes with 45" x 24¾" x 6"
piece of insulation. See Figure 8.
WITH NO VENT OPTION
To remove the drain access panels in the rear of this
section, simply remove the front door/cover from the
box. Rear drain access panels are now visible on both
right-hand and left-hand sides in rear of box.
WITH COMMERCIAl ROOM VENTIlATOR
1. Open hinged front doors.
2. Disconnect unit power to eliminate shock hazard.
3. Remove front cover/door of CRV vent package.
(Can leave filter access panels in place.)
4. Unplug wires coming in on left side from upper
unit section.
5. Unplug two wire harness from front (intake) blower.
6. Remove two (2) screws securing front (intake)
blower and slide blower out of unit.
7. Remove four (4) screws that retian the partition
behind/beneath intake blower removed in Step #6.
8. Rear drain access panels are now visible on both
right-hand and left-hand sides in rear of box.
