 The air conditioner should be used only for the applications for which it has been designed: the indoor unit is not

suitable to be installed in areas used for laundry.

 Our units must be installed in compliance with the spaces indicated in the installation manual to ensure either

accessibility from both sides or ability to perform routine maintenance and repairs. The units’ components must be

accessible and that can be disassembled in conditions of complete safety either for people or things. For this reason,

where it is not observed as indicated into the Installation Manual, the cost necessary to reach and repair the unit (in

safety, as required by current regulations in force) with slings, trucks, scaffolding or any other means of elevation won’t

be considered in-warranty and charged to end user.

Power supply line, fuse or circuit breaker

 Always make sure that the power supply is compliant with current safety standards. Always install the air conditioner

in compliance with current local safety standards.

 Always verify that a suitable grounding connection is available.

Installation

As soon as the air handler is received, it should be inspected for possible damage during transit. If damage is evident, the

extent of the damage should be noted on the carrier’s freight bill. A separate request for inspection by the carrier’s agent

should be made in writing. Before installing the air handler you should check the cabinet for screws or bolts which may

have loosened in transit. There are no shipping or spacer brackets which need to be removed before startup. See local

Distributor for more information. Samsung assumes no liability for freight damage. Also check to be sure all accessories

such as heater kits, and coils are available. Installation of these accessories should be accomplished before the air handler

is set in place or the connecting of the wiring, electric heat, ducts or piping.

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

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

service port on the suction pipe. Ensure that the service port cap is installed before pressurizing the system.

Air Handlers with DX type evaporator coils require liquid and suction piping sized in accordance with condensing unit

manufacturer’s instructions. The evaporator coils have sweat copper connections. Refrigerant lines should be soldered

with silver solder or high temperature brazing alloy.

DRY NITROGEN MUST BE FLOWED THROUGH REFRIGERANT LINES DURING SOLDERING OPERATION.

REFER TO OUTDOOR UNIT INSTALLATION MANUALS FOR PRESSURE CHECKING AND VACUUM DRYING

PROCEDURES.

There are two refrigerant pipes of differing diameters:

 A smaller one for the liquid refrigerant

 A larger one for the gas refrigerant

 The inside of copper pipe must be clean & have no dust.

Prepare the connecting pipe referring to the list below.

Cutting the pipes

1. Make sure that you prepared the required tools. (pipe cutter, reamer, aring tool and pipe holder)

2. If you want to shorten the pipe, cut it using a pipe cutter ensuring that the cut edge remains at 90° with the side of the pipe.

There are some examples of correctly and incorrectly cut edges below.

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.

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.

 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 thicker

insulator.

NOTE

Always make the seam of pipes face upwards.

2. Wind insulating tape around the pipes and drain hose avoiding to compress the

insulation too much.

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
