Chart of shapes of branch piping parts
• FDCP1008HES3 [Branch pipe set: DIS-WA × 2set, DIS-WB × 1set]
Notes (1) 1 to 4 in the drawing include parts provided in the branch piping set. It shows the codes for the shapes of different-diameter connections.
(2) Branch piping should always be arranged to have level or perpendicular branch. (Refer to the 72 page for details.)
(b) Piping work
Request
¡ Use the pipe made of following material. Moreover, it is very convenient for you to use the separately sold piping kit.
Material: Phosphor deoxidized seamless copper tube (C1220T, JIS H3300)
¡ In the case of this unit, condensation water is also generated on the liquid piping. Insulate both of the liquid piping and
gas piping perfectly.
¡ In the case of heat pump type unit, the maximum temperature of the gas piping reaches approx. 120˚C, therefore use the
insulation material which has sufficient heat resistance.
¡ When bending the pipe, bend it with large radius as much as possible. Do not bend the same portion of pipe repeatedly.
¡ Do not let dust, chips or water enter the pipe while pipe working.
¡ The flared connection for refrigerant piping is required. Flare the pipe after in-
serting the flared nut into the pipe.
¡ Tighten the flared connection firmly using 2 of spanners. Comply with the fol-
lowing value for tightening torque of the flared nut.
¡ In the case of brazing connection, perform brazing while flowing nitrogen gas in
the pipe to prevent generation of oxide film inside the pipe without fail.
IMPORTANT
¡ Take care so that the piping to be worked does not contact the parts contained in the unit.
If it contacts the inner parts, abnormal sound or vibration may occur.
1) Refrigerant pipe connection
a) The piping can be taken out to the right, left front, rear and botton directions.
b) Cut the plate at the knockout portion on the piping penetration section with necessary minimum size.
c) Mount the attached edging by cutting it to the appropriate length before connecting the pipe.
