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.
f 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. f 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.
Accessories The following accessories are supplied with the indoor unit. The type and quantity may differ depending on the model. Bushing bracket Insulation pipe Cable-tie Drain hose User manual Installation manual Clamp Selecting the installation location Indoor unit f There must be no obstacles near the air inlet and outlet. f Install the indoor unit on a ceiling that can support its weight.
Space requirements for indoor unit • The units must be installed according to distances declared, in order to permit accessibility from each side, either to guarantee correct operation of maintenance or repairing products. The unit’s parts must be CAUTION reachable and completely removable in a safe manner (for people or property). • Do not hold the discharge outlet while carrying the indoor unit to avoid the possibility of breakage.

Connecting the refrigerant pipe There are two refrigerant pipes of different diameters: f A smaller one for the liquid refrigerant f A larger one for the gas refrigerant f The inside of copper pipe must be clean and have no dust or debris. 1.
Cutting/flaring the pipes 1. Make sure that you have the following required tools: pipe cutter, reamer, flaring 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.
Performing leak test & insulation Leak test LEAK TEST WITH NITROGEN (before opening valves) In order to detect basic refrigerant leaks, the refrigerant pipes and system must be pressurized with nitrogen (using a pressure regulator) at a pressure above 4.1 MPa (595 psig ). This should be done before connecting a vacuum pump or releasing the factory R-410A charge.
Performing leak test & insulation 5. Select the insulation of the refrigerant pipe. f Insulate the gas side and liquid side pipe. Thickness is selected according to pipe size. f Indoor temperature of 30 °C (86 °F) and humidity of 85% is the standard condition. If installing in a high humidity condition, increase insulation by one size by referring to the table below.
Drain pipe and drain hose installation Care must be taken when installing the drainpipe and drain hose for the indoor unit so that condensate water is drained correctly. Fix the flexible hose to the drainpipe. f Push the supplied drain hose as far as possible over the drain socket. f Tighten the metal clamp as shown in the picture.
Drainpipe and drain hose installation Drainpipe connection 1. The drain pipe should be installed within 100mm (4”) from the flexible hose, turn upward 100mm (4”) to 550 mm (22”),then turn downward 20 mm (3/4”) or more. 2. Install horizontal drainpipe with a slope of 1/100 or greater and support with hangers spaced 1~1.5 m (3’ 3”~4’ 11”) apart.
Centralized Drainage 1. Install main air vent in front of the farthest indoor unit from the main drain when more than three indoor units are connected to the a common drain pipe. 2. Individual air vents may need to be installed to prevent water flow back at the top of each indoor unit drain pipe. 1~1.5 m(3’...
Connecting power and communication • Always remember to connect the refrigerant pipes before installing the electric connections.
