FH18BTA IM_E_23837 8/11/05 3:24 PM Page 4 Preparation for installation When deciding on the location of the air conditioner with the owner, the following restrictions must be taken into account. General Do NOT install the air conditioner in a location where it will come into contact with the following elements: ◆ ◆ ◆ ◆ ◆ Combustible gases Saline air Machine oil Sulphide gas Special environmental conditions If you must install the unit in such conditions, first consult your dealer.
FH18BTA IM_E_23837 8/11/05 3:24 PM Page 5 Deciding on where to install the indoor unit Indoor Unit ◆ Select a convenient location that permits the air to reach every corner of the area to be cooled. ◆ Pre-plan for easy and short routing of the refrigerant tubing and wiring to the outdoor unit. ◆ There should be no flammable gas, alkaline, substances present in the air. ◆ Avoid location where obstacles preventing good air circulation are present.

When the directions are selected, drill 3-1/8'' (100mm, for pipe and cables) and 1-3/4'' (40mm, for drain hose) diameter holes on the wall so that it slants slightly downwards toward the outdoor for smooth water flow. Note 300mm or more ◆ Use the pattern sheet to select pipe directions.
FH18BTA IM_E_23837 8/11/05 3:24 PM Page 10 Purging the unit On delivery, the indoor unit is loaded with an inert nitrogen gas. All this gas must therefore be purged before connecting the assembly piping. To purge the inert gas, proceed as follows. Unscrew the caps at the end of each pipe. Result: Note E-10 All inert gas escapes from the indoor unit.
FH18BTA IM_E_23837 8/11/05 3:24 PM Page 11 Connecting the refrigerant pipe 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 & has no dust. 1 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 6.35 mm (1/4") 9.
FH18BTA IM_E_23837 8/11/05 3:24 PM Page 12 Cutting / Flaring the pipes 1 Make sure that you have the required tools available (pipe cutter, reamer, flaring tool and pipe holder). 2 If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure that the cut edge remains at a 90° angle with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.
FH18BTA IM_E_23837 8/11/05 3:24 PM Page 13 Performing leak test & insulation Leak Test Before completing the installation (insulation of the hose and pipe), you must check that there are no gas leaks. 1 After closing both high and low stop valve of the outdoor unit, inject nitrogen gas into refrigerant pipe. 2 By using soap bubbles, check leak on flare nut connection of pipes. 3 Purge nitrogen gas after finishing leak test.
FH18BTA IM_E_23837 8/11/05 3:24 PM Page 14 Drain hose installation Care must be taken when installing the drain hose for the indoor unit to ensure that any condensation water is correctly drained outside. When passing the drain hose through the hole drilled in the wall, check that none of the following situations occur. 5 cm less The hose must NOT slope upwards. The end of the drain hose must NOT be placed in water. Do NOT bend the hose in different directions.
FH18BTA IM_E_23837 8/11/05 3:24 PM Page 15 Connecting the connection cord The indoor unit is powered from the outdoor unit via the connection cord. 1 Remove the screw on the electrical component box and remove the cover plate. 2 Route the connection cord through the side of the indoor unit and connect the cable to terminals; refer to the figure below. 3 Route the other end of the cable to the outdoor unit through the ceiling & the hole on the wall.
