This manual explains how to install an indoor unit with a split system with two SAMSUNG units. The use of other types of units with different control systems may damage the units and invalidate the warranty. The manufacturer shall not be responsible for damages arising from the use of non compliant units.
Safety precautions 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.
A Accessories The following accessories are supplied with the indoor unit. The type and quantity may differ depending on the specifications. ❈ Only AM018JNMPCH/AA include the last four accessories. Insulation cover Thermal insulation A Thermal insulation B Thermal insulation (use for refrigerant pipe) (use for refrigerant pipe) (use for drain hose) User's manual...

A Selecting the installation location Indoor Unit There must be no obstacles near the air inlet and outlet. Install the indoor unit on a ceiling that can support its weight. Maintain sufficient clearance around the indoor unit. Make sure that the water dripping from the drain hose runs away correctly and safely. The indoor unit must be installed in this way, that they are out of public access.

A Indoor unit installation It is recommended to install theY-joint before installing the indoor unit. Place the pattern sheet on the ceiling at the spot where you want to install the indoor unit. Note Since the diagram is made of paper, it may shrink or stretch slightly due to temperature or humidity.
Indoor unit installation Noise will increase 3~6 dB(A) when the air flow enters from the bottom side (Only for Slim Duct Type product). Caution Air Flow For HSP Duct (AM024/027/030/036/048JNHDCH),2 Pad- Cushion should be removed before installing air conditioner. Caution...
Purging the unit On delivery, the indoor unit is loaded with inert gas. All this gas must therefore be purged before connecting the FNLD assembly piping. To purge the inert gas, proceed as follows. Unscrew the pinch pipe at the end of each refrigerant pipe. Result: All inert gas escapes from the indoor unit.
Page 23
A Connecting the refrigerant pipe Remove the pinch pipe on the pipes and connect the assembly pipes to each pipe, tightening the nuts, first manually and then with a torque wrench, a spanner applying the following torque. Outer Diameter Torque inch 6.35 14~18...
A Cutting/flaring the pipes Make sure that you prepared the required tools. (pipe cutter, reamer, flaring tool and pipe holder) 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.
A 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 R410A, it’s responsible of installer to pressurize the whole system with nitrogen (using a pressure regulator) at a pressure above 4.1MPa(594.7 psig) (gauge).
Page 26
Caution All refrigerant connection must be accessible, in order to permit either unit maintenance or removing it completely. Select the insulator of the refrigerant pipe. Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size. Indoor temperature of 30°C(86°F) and humidity of 85% is the standard condition.
Performing leak test & insulation Caution Install the insulation not to get wider and use the adhesives on the connection part of it to prevent moisture from entering. Wind the refrigerant pipe with insulation tape if it is exposed to outside sunlight. Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or hanger of pipe.
