9 FINAL INSTALLATION CHECKS<br />
Useful Functions (SM802AT-E only)<br />
In addition to the code checking by remote controller of the indoor unit, troubles of the outdoor unit can be diagnosed by <strong>LE</strong>D indications on the<br />
cycle control P.C. board of the outdoor unit. Utilize them for various checks.<br />
For the check by remote controller of the indoor unit, refer to the installation Manual of the indoor unit.<br />
Before a check, confirm each bit of the DIP switch is set to OFF position.<br />

Installation/Servicing Tools<br />
In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged accidentally, the service port diameter<br />
of the outdoor unit control valve (3 way valve) has been changed. (1/2 UNF 20 threads per inch)<br />
• In order to increase the pressure resisting strength of the refrigerant piping, flare processing diameter and size of opposite side of flare nuts<br />
has been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)<br />

Changes in the pr oduct and components<br />
As pressure is high, it is impossible to measure by means of conventional gauge. In<br />
order to prevent any other refrigerant from being charged, each port diameter is<br />
changed.<br />
In order to increase pressure resisting strength, hose materials and port size are<br />
changed (to 1/2 UNF 20 threads per inch).<br />
When purchasing a charge hose, be sure to check the port size.<br />
As pressure is hight and gasification speed is fast, it is difficult to read the indicated<br />
value by means of charging cylinder, as air bubbles occur.<br />
The size of opposite sides of flare nuts have been increased. Incidentally, a common<br />
wrench is used for nominal diameters 1/4 and 3/8.<br />
By increasing the clamp bar’s receiving hole, strength of spring in the tool has been<br />
improved.<br />
Used when flare is made with using conventional flare tool.<br />
Connected to the conventional vacuum pump. It is necessary to use an adapter to<br />
prevent vacuum pump oil from flowing back to the charge hose.<br />
The charge hose connecting part has two ports-one for conventional refrigerant (7/16<br />
UNF 20 threads per inch) and one for R410A. If the vacuum pump oil (mineral) mixes<br />
with R410A a sludge may occur and damage the equipment.<br />
Exclusive for HFC refrigerant.<br />

• Incidentally, the “refrigerant cylinder” comes with the refrigerant designation (R410A) and protector coating in the U. S’s ARI specified rose<br />
color (ARI color code: PMS 507).<br />
• Also, the “charge port and packing for refrigerant cylinder” require 1/2 UNF 20 threads per inch corresponding to the charge hose’s port size.<br />
