INSTALLATION DIAGRAM Thermal Insulation Indoor Unit Drain Piping Wrap the insulated pipe with the nishing tape from bottom to top Front Panel Air Filter (behind the grille) Air Intake Grille Air Discharge Louver Air Intake Air Intake Outdoor Unit Air Discharge INSTALLATION OF THE INDOOR UNIT Preliminary Site Survey Be sure to read this manual before installing the air-conditioner indoor unit. - Page 8 • Ensure a location where: Drainage can be done easily. Convenient for wiring and piping. Which have enough space for installation and service work. Where no risk of ammable gas leakage. When free from any obstacles in path of cool air discharge and warm air return and must allow spreading of air throughout the room (near the center of the room).
- Page 9 Drain Piping Work • Avoid installing the drain pipe in upward gradient after the drain connection. Flexible Hose • Ensure the height of drain pipe from ceiling is 700mm or Pipe Clamp less if it is necessary to increase the height of drain pipe to prevent water leak.
- Page 10 NOTE Install the front frame panel rmly to prevent cool air leakage which will cause condensation and water dripping. Indoor Unit Cool Cool Air Leak Air Leak Ceiling Board Ceiling Board Panel Panel Grille Lock Cover (The moving part protection for user direct touching) Grille lock cover must be installed as the gure below.
- Page 11 Wires Installation Figure A Figure A and Figure B shows the location of cover wire in FH(Y)C unit. Steps to install power supply wires and wires from outdoor unit. Remove wire cover by removing 2 screws as shown in Figure C. Wires will go through the hole as shown in Figure D and E respectively without crossing the height of the hole.
- Page 12 INSTALLATION OF THE OUTDOOR UNIT As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum cooling capacity, the location selected for outdoor unit should fulfill the following requirements: • Install the condensing (outdoor) unit in a way such that the hot air distributed by the outdoor condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge air).
-
Page 13: Installation Clearance
INSTALLATION CLEARANCE • Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to smooth air ow. Select the coolest possible place where intake air should not be hotter than the outside temperature (refer to operating range). - Page 14 Piping Works And Flaring Technique • Do not use contaminated or damaged copper tubing. If any pipings, evaporator or condenser had been exposed or had been opened for 15 seconds or more, the system must be vacuumed. Generally, do not remove plastic, rubber plugs and brass nuts from the valves, fittings, tubings and coils until it is ready to connect suction or liquid line into valves or fittings.

Page 20: Vacuuming And Charging
VACUUMING AND CHARGING Vacuuming is necessary to eliminate all moisture and air from the system. The series II Outdoor Unit is provided with flare valve fittings. Vacuuming The Piping And The Indoor Unit Refrigerant Piping Allen key Flare nut Except for the outdoor unit which is pre-charged with refrigerant, the indoor unit and the refrigerant connection pipes must be air- purged because the air containing moisture that remains in the refrigerant cycle may cause malfunction of the compressor. -
Page 21: Additional Charge
Outdoor RYD50JETLK Additional charge [g/m] Example: FHC20JEVLK & RD20JEVLK with 13m piping length, additional piping length is 5.5m. Thus, Additional charge = 5.5[m] x 22[g/m] = 121[g] ! CAUTION * When connect with FHC25JEVLK and FHYC25JEVLK, additional 0.2kg refrigerant charge is needed for 3.0m to 7.5m piping length. - Page 22 SPECIAL PRECAUTIONS WHEN CHARGING UNIT WITH SCROLL COMPRESSORS These precautions are intended for use with Scroll compressors only with R22 refrigerants but are not applied to others competitive Scroll compressors. Scroll compressors have a very high volumetric efficiency and quickly pump a deep vacuum if there is insufficient refrigerant in the system or if refrigerant is added too slowly.
