ATTENTION
Please read this entire guide (both the installation and operation portions) thoroughly prior to installation. Pay careful
attention to all safety warnings and notices.
As a professional installer you have an obligation to know the product better than the customer. We cannot
overemphasize the importance of proper installation.
It is the installer’s responsibility to properly install the unit. Installation must be in conformance with all applicable local
and/or national codes.
Often during installation or repair it is possible to place yourself in a position which is more hazardous than when the
unit is in operation.
It is your responsibility to install the system safely and to know it well enough to be able to instruct a customer in its
safe use. The precautions listed in this Installation Manual are intended as supplemental to existing practices. However,
if there is a direct conflict between existing practices and the content of this manual, the precautions listed here take
precedence.

INSTALLATION RULES
For optimum performance and to avoid malfunctions or dangerous situations, the location of the unit must meet the
following criteria:
•Maintain the minimum clearances as indicated in the diagram on the right.
•The unit must be attached to a wall of material suitable of supporting the weight of the unit.
•If using the Innova Nebulizer for condensate removal the unit must be mounted a minimum of 9.5” from the
floor to accommodate the height of the nebulizer.
•When used exclusively to heat, avoid “high wall” installation in rooms where the ceiling is greater than 10 feet
high.
•Make sure that inside the room nothing obstructs the air flow to the return air grille and the supply air louver.
•Make sure than on the outside nothing obstructs the louvers (plants and leaves, panelling, shutters, dense grates
or grids, etc.)
•The unit must be installed against an exterior wall or perpendicular to an outside wall using a special order Side
wall installation kit.
•Check that there are no structures or systems (beams, pillars, hydraulic pipes, electrical cables etc.) in the part of
the wall that must be drilled.
•Do not install the unit directly above another electrical appliance (TV, radio, fridge, etc.) or above a source of
heat.
WARNING
EXCESSIVE WEIGHT HAZARD
Use two people when lifting and installing the unit. The unit is
unbalanced on the right (compressor side) Failure to do can result in
back or other injury.

Unit should be installed no closer than
8” from the ceiling and no closer than
2” from the floor.
Leave a minimum of 2.5” on the side of
the unit.

FALLING OBJECT HAZARD
Failure to mount the unit securely can result in property damage,
injury or death.

SIDEWALL ADAPTER (SWA)
Where it’s not feasible or practical to mount the HPAC 2.0 on an exterior wall, HPAC 2.0 can be mounted on a wall
perpendicular to the exterior using the SWA.
The SWA is recessed into the wall and includes additional fans that assist the supply and exhaust air
through the bend. SWA is available in a right or left side application. Contact your dealer if you require this part
COF04IC2II.

15
OCCUPANCY SENSOR CONNECTION
HPAC 2.0 can be connected to an occupancy sensor such as; open window contact, on/off remote, infrared presence
sensors, enabling badge, etc. to activate and deactivate the unit.
When the contact opens (very low voltage, connected to a free non-live contact) the unit is placed in standby mode and
CP displays on the screen (note, CP stand for Contatto Presenza - Contact Present in Italian)
Use only double insulated cable.
Note: For the versions with auxiliary electric heat resistance, in order to prevent internal overheating, do not disconnect
voltage from the unit abruptly! Use the CP contact that places the unit in standby mode, guaranteeing the required
postoperative ventilation.

STEP 1 Attach the mounting template to the wall with tape
STEP 2 Drill the holes for the XVentBox in accordance with the specifications of the grille style you are
using.
STEP 3 Afix the wall mount bracket as indicated on the Template. The bracket must be affixed to studs
or other suitable material that can safely support the weight of the unit. Do not use hollow wall
anchors.
STEP 4 If using an external drain for condensate, drill a hole as indicated on the template for the
condensate to drain outside. Make sure to drill the hole at a 3 degree downward angle.
STEP 5 If the anti-lifting bracket hole does not line up with a stud, install a hollow wall anchor.
STEP 6 If hardwiring the unit make sure the junction box and appropriate connections are located in
the electrical connection area.

NOTES

CONDENSATE DRAIN OPTIONS
HPAC 2.0 is equipped with a pump and spray head which sprays the collected condensate on to the heat exchanger
coil in cooling mode. This evaporates the condensate, eliminating the need for a condensate drain. In heating mode, or if
used to cool in low ambient temperatures (below 73.5°F) this procedure is not feasible and therefore a condensate drain is
required.
Determine where the condensate drain will be located:
IN-WALL DRAIN
This is the best type of drain where it is installed by a plumber inside the wall
DIRECT EXTERIOR DRAIN
This is the easiest type of drain where the condensate drips straight outside.
NEBULIZER:
Innova offers an optional nebulizer kit, which atomizes the condensate in heat mode as a fine mist through an additional
exterior hole.
Follow appropriate instructions on the following pages depending on your particular type of installation.
Note: The unit does not drain the condensate directly into the drain pipe, but rather it collects into a lightly heated
collection pan (to eliminate icing up of the liquid) where a solenoid valve controls the flow of the condensate from the
internal collection tray to the drain pipe once the maximum level has been reached.

19
IN-WALL CONDENSATE DRAIN
For optimum performance and aesthetics, when possible use an internal wall drain.
NOTICE When connecting the condensate drain, be careful not to squeeze
the rubber hose
STEP 1 Have licensed plumber install a PVC drain pipe with a minimum 3/4” inside diameter and
a 45 Degree fitting at the top. The mouth of the 45 degree fitting should be lined up with
the condensate hole on the template
STEP 2 Test the drain by pouring water into it
STEP 3 Cut down the attached rubber drain pipe, so that at least 4 inches of rubber pipe will fit
inside the internal PVC drain.
STEP 4 Gently push the attached rubber drain inside the internal PVC drain
STEP 5 Check to make sure that the rubber pipe is snugly inside the PVC pipe and it will not “pop
out”.

20
DIRECT EXTERNAL DRAIN
Make sure to check applicable local laws if this is type of drainage is permissible. Check that the expelled water does will
cause any damage or problems to people or objects. During winter, this water may create sheets of ice outside.
Drainage is by gravity only. For this reason, it is essential that the discharge drain pipe have a minimum 3% slope
downwards at every point. The pipe can be rigid or flexible with a minimum ¾” diameter.
If the line flows into a sewer system, it is necessary to add a siphon before placing the pipe into the sewer drain. This
siphon must be placed at least 12” under the drain pipe.
