Indoor unit installation

Refrigerant pipe work must be done before installing the indoor unit.

Location

Access for servicing is an important factor in the location of any air handler. Provide a minimum of 30 inches in front of
the appliance for access to the control box, heating elements, blower and air filters. This access may be provided by a
closet door or by locating the appliance so that a wall or partition is not less than 30 inches from the front access panel.
Location is usually predetermined. Refer to figure below. Check with owner’s or dealer’s installation plans. If location
has not been decided, consider the following in choosing a suitable location.

1.

Select a location with adequate structural support, space for service access, and clearance for return and supply
duct connections.

2.

Normal operating sound levels may be objectionable if the air handler is placed directly over or under some rooms
such as bedrooms, study, etc.

3.

Caution should be taken to locate the unit so that supply and return air ducts are about the same length causing
even air distribution of supply and return air to and from the living spaces.

4.

Locate appliance where electrical supply wiring can be easily routed to main electrical panel and where electrical
wiring will not be damaged.

5.

Locate appliance where control wiring can be easily routed to the controller and where the wiring will not be
damaged.

6. Locate appliance where refrigerant lines can be easily routed from the evaporator coil to the system.

7.

Locate the appliance where condensate lines can be easily routed to an available drain. Be sure to route
condensate drain piping so as not to obstruct access to the air filter.

8.

The coil is installed in a draw-thru application and will create a negative pressure situation in the condensate drain
system. To prevent condensate from being drawn into the blower it is recommended to trap the primary (Main)

and secondary (Overflow) drain line. Refer to Drain Pipe and Drain Hose section in these instructions. If the
secondary drain is not used, it must be capped. This unit has a connection terminal for drain system monitoring.
Refer to Wiring Work section for information regarding connection of field-provided condensate overflow devicesin
these instructions.

9.

The draw-thru design will cause exterior surface of cabinet to sweat when unit is installed in a non-conditioned space
such as an attic or garage. Installer must provide protection such as full size auxiliary drain pan on all units installed in a
non-conditioned space to prevent damage from condensation runoff. Some states,
cities and counties require additional insulation to be installed on the exterior casing of the air handler to prevent
sweating. Refer to the state, city, county or local code for insulation requirement to be sure the installation is in
compliance. It is recommended that air handlers installed in non-conditioned spaces be insulated on the exterior of the
entire cabinet, including the front access panel with one (1) inch thick fiberglass with the vapor barrier on the outside.

Clearance – Access for service

30" minimum

Typical Closet Installations

Provisions shall be made to permit the air in the rooms and the living spaces to return to the air handler. Failure to comply may
cause a reduction in the amount of return air available to the blower, causing reduced air flow resulting in improper heating and
cooling of the living space. The reduced air flow may cause the air handler to cycle on the limit causing premature heating
element failure (if electric heat kits are installed).

Upflow Accessory Filter Box Kit

An accessory filter box kit can be used on the return air end of the air handler when configured in the upflow position.
The filter kit is placed over the return plenum in the floor and sealed to the plenum using sealant or caulking material
and/or tape. The air handler is placed on top of the return filter box and the return opening sealed to prevent leaks.

NOTE: Make sure the flow arrow on the air filter is pointing towards the coil.

Performing leak test & insulation

Leak test

LEAK TEST WITH NITROGEN (before opening valves)

In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R-410A, it’s responsible of
installer to pressurize the whole system with nitrogen (using a pressure regulator) at a pressure above 595 PSI (4.1MPa).

LEAK TEST WITH R-410A (after opening valves)

Before opening valves, discharge all the nitrogen in the system and create vacuum. After opening valves check
leaks using a leak detector for refrigerant R-410A.

•

Discharge all the nitrogen to create a vacuum and charge the system

CAUTION

Insulation

Once you have checked that there are no leaks in the system, you can insulate the piping and hose.

1.

To avoid condensation problems, place T13.0mm (0.51”) or
thicker Acrylonitrile Butadien Rubber

separately around each

refrigerant pipe.

NOTE

Always make the seam of pipes face upwards.

No gap

NBR [T13.0mm (0.51”) or thicker]

2.

Wind insulating tape around the pipes and drain hose avoiding to
compress the insulation too much.

Indoor unit

Be sure to overlap

•

Must fit tig

htly against

body without any gap.

CAUTION

3. Finish wrapping insulating tape around the rest of the pipes leading to

the outdoor unit.

4.

The pipes and electrical cables connecting the indoor unit with the
outdoor unit must be fixed to the wall with suitable ducts/straps.

• All refrigerant connection must be accessible, in order to
permit either unit maintenance or removing it completely.

CAUTION

•

You can contact the gas side and liquid side pipes but the pipes
should not be pressed together tightly.

•

When contacting the gas side and liquid side pipe, use 1 grade
