8. SPECIAL PRECAUTIONS FOR R407C Special precautions when dealing with refrigerant R407C unit 1) WHAT IS NEW REFRIGERANT R407C? R407C is a zeotropic refrigerant mixture which has zero ozone depletion potential and thus conformed to the Montreal Protocol regulation. It requires Polyol ester oil (POE) oil for its compressor's lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22.
c) Ensure that the compressor is not expose to open air for more than the recommended time specified by its manufacturer (typically less than 10 minutes). Removed the seal-plugs only when the compressor is about to be brazed. d) The system should be thoroughly vacuumed to 1.0 Pa (-700mmHg) or lower. This vacuuming level is more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.
9. INSTALLATION OF INDOOR UNIT Caution : Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them. PRELIMINARY SITE SURVEY • • • Beam • Electrical supply and installation is to conform to local authority's (e.g. National Electrical Board) codes and regulations. Voltage supply fluctuation must not exceed ± 10% of rated voltage. Electricity supply lines must be independent of welding transformer which can cause high supply fluctuations.
UNIT HANGING Indoor Unit Ceiling Board 35.0 mm ACK-A ACK-B • Confirm the pitch of the hanging rod is 790.0mm X 620.5mm (ACK-A) / 600.0mm x 582.0 mm (ACK-B). • Hold the unit and hang it on the hanging rod with the nut and washer. • Adjust the unit height to 35.0 mm (ACK-A) / 25.0 mm (ACK-B) between the indoor unit bottom surface and the ceiling surface. • Confirm with a level gauge that the unit is installed horizontally and tighten the nut and bolt to prevent unit falling and vibration.
PANEL INSTALLATION • The front panel can only be fitted in one direction, follow the piping direction. (Follow piping arrow sticker on front panel). • Be sure to remove the installation template before installing the front panel. • Open the air intake grille by pulling back the catchers and remove it together with filter from panel. • Install the front frame panel onto the indoor unit by using 4 screws and tighten it completely to prevent cool air leakage.
AIR INTAKE GRILLE INSTALLATION • Before installed the air intake grille, make sure the air filter is clip properly to the air FRAME (OPTIONAL ITEM) intake grille. • Install the air intake grille together with the air filter to the front panel. IONIZER FILTER (OPTIONAL ITEM) • The grille can be fit in any direction, when selecting direction, the ceiling design and grille operability should be considered.
11. REFRIGERANT PIPING WORK Refrigerant piping is important in particular. Refrigeration cycle of the split air conditioner is realized by the perfect piping work. PIPING LENGTH AND ELEVATION If the piping is too long, both the capacity and reliability of the unit will drop. As the number of bends increases, resistance to flow of refrigerant increases, thus lowering the cooling capacity and as a result overloading the compressor which may cause the compressor to become defective.

14. ACCESSORY PARTS SHORT DUCT SPECIFICATION • The indoor unit is provided with air discharge and air intake "knock-out". hole for duct connection. However the connection of the short duct for air discharge is possible on only one side. • The use of short duct for air discharge will improve airflow distribution if there is an obstruction (such as alighting fixture) or in a long, narrow room or an L-shaped room. It is also used for air conditioning of two rooms simultaneously.
SEALING MATERIAL • It is possible to seal one of the four air discharge outlet (sealing two or more air discharge outlet could cause a malfunction). Remove the front panel and inserting the seal material into the air discharge outlet at the indoor unit to seal the air outlet. The sealing material is the same length as the longer air discharge outlet. If it is desired to seal the shorter air discharge outlet, cut the sealing material to shorten it.
