Installation Caution Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them. (1) Installation of Indoor Unit Preliminary Site Survey • Electrical supply and installation is to confirm to local authority’s (e.g. National Electrical Board) codes and regulations.
Page 16
Pipings Do not use contaminated or damaged copper tubings. If pipings, evaporator or condenser is exposed or had been opened for 15 seconds or more, vacuum and purge with field supplied refrigerant. Generally, do not remove plastic, rubber plugs or caps from fittings, tubings and coils until ready to connect suction or liquid line into fittings.
Page 17
(2) Installation of Outdoor Unit AMC Series 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 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 18
(3) Refrigerant Piping Field Piping To ensure satisfactory operation and performance, the following points should be noted for the field piping arrangements of the complete refrigerant cycle. a) Liquid loops or oil traps must be provided according to the position of the outdoor and indoor units (depend- ing on whether the indoor unit is above or below the outdoor unit).

Guidelines Of Field-charging Air Conditioning Systems With Scroll Compressors These guidelines are intended for use with Scroll compressors only with R, R07C, Ra, R0A, R07, and R0A refrigerants. They do not apply to reciprocating compressors or competitive Scroll compressors. Field-charging - Some Precaution Points 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.

Typical service valves Found on the outdoor unit Shredder valves Shredder core Shredder valve with core removed Shredder valve with core in place Most split systems have a suitable connection on the outdoor unit Shredder valves provide easy system access for pressure reading and addition of refrigerant. On small sys- tems, they provide a reasonable connection for evacuation also.
Page 21
Charging Recommendations Charging liquid in a CONTROLLED manner into the suction side until the system is full. This recommen- dation does not hold true for reciprocaing compressors where liquid charging into the suction side could cause severe damage. Charging Cylinder on Scale Close-up of Scale Carefully monitor the suction and discharge pressures - ensure that the suction pressure does not fall below psig (.7 bar) at any time during the charging process.
Page 22
(5) Additional Charge • The refrigerant charge has already charged into the outdoor unit. For the piping length of 7.m, additional refrigerant charge after vacuuming is not necessary. • For AMC 7/00D/ER, please refer to the table below: Liquid Pipe Size, inch Additional Charge, kg/meter /”...

Special Precaution When Dealing With Refrigerant R407C Unit (1) What is new refrigerant R407C? R07C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus, conforms to the Montreal Protocol regulation. It requires Polyol-ester (POE) oil for its compressor’s lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R. (2) Components Mixture of composition by weight: R(%), R(%), Ra(%) (3) Characteristic...
Page 24
(c) Ensure that the compressor is not exposed to open air for more than the recommended time specified by its manufacturer (typically less than 0 minutes). Remove the seal-plug only when the compressor is about to be brazed. (d) The system should be thoroughly vacuumed to .0 Pa (-700mmHg) or lower. This vacuuming level is more stringent then R system so as to ensure no incompressible gas and moisture in the system.
Page 25
(6) Overall Checking • Ensure the following, in particular: . The unit is mounted solidly and rigid in position. . Piping and connections are leak proof after charging. . Proper wiring has been done. • Drainage check – pour some water into drain pan. •...

The design concept of the Condensing Unit is such that all servicing can be done from the front and side of the unit. Upon removal of front and side panel, all the electrical “terminal box”, fan and motor assembly and compressor are easily accessible.
12. TROUBLESHOOTING When a malfunction of the air conditioner unit is detected, immediately switch off the main power supply before proceeding with the following troubleshooting procedures. The following are common fault conditions and simple troubleshooting tips. If any other fault conditions which are not listed occur, contact your nearest local dealer.
