These oxidation bubbles (Brazing) are then carried along inside the pipes to cause damage to various members of the system such as valves or compressors and the system ceases to function properly.
Page 21 Si33-003.book Page 17 Monday, June 25, 2001 9:06 AM SiE33-003 Installation Covering of Covering is an extremely important operation as it prevents water, dirt or dust from getting inside Refrigerant Pipes the pipes. Moisture inside the pipes was a constant source of trouble in the past. The utmost care is required to nip this problem in the bud.

The use of “hard solder” is essential. The R-407C Plus Series uses a wide range of piping sizes. You should therefore be careful when selecting the nozzle tip.
Page 25 Si33-003.book Page 21 Monday, June 25, 2001 9:06 AM SiE33-003 Installation Brazing a) Brazing work should be carried out such that the final result is directed either downwards or sideways. An upward direction should be avoided wherever possible. (to prevent leakage) b) Liquid and gas pipe branches should always be dealt with in the specified way with attention being paid to the direction of the fitting and its angle.

Page 34 Si33-003.book Page 30 Monday, June 25, 2001 9:06 AM Installation SiE33-003 Choosing a General Vacuum Pump Refrigerant piping content volume of the Plus Series is larger than the VRV Inverter Series, and consequently takes more time for vacuum drying. If you have time to spare, you may use the same vacuum pump, but if you want to save time, you will have to use a pump with higher exhaust velocity (exhaust volume).
Page 35 Si33-003.book Page 31 Monday, June 25, 2001 9:06 AM SiE33-003 Installation 2. Vacuum pump maintenance Because of their nature, most vacuum pumps contain large amounts of oil which lubricates bearings, etc., and functions to enhance airtightness of pistons. When using a vacuum pump to discharge air from refrigerant piping, moisture in the air tends to get mixed in with the oil.

These refrigerants use ether oil for refrigerant oil instead of suniso oil. If oil of an incorrect type is mixed in R410A and R-407C, sludge results in the refrigerants and causes equipment problems. Therefore, gauge manifolds and charge hoses that are used with a previous refrigerant (R22) cannnot be used for products that use new refrigerants.
