12.1.1.2 Remote Controller
 Signals may not be transmitted and received
correctly when the remote controller is operated
while in the holder. Take the remote controller in
your hand to operate the unit.
 Mount the holder in a location that is not subject to
the effects of heat (direct sunlight and stoves,
etc.).
12.1.2 Selection of Pipe and Heat Insulation Materials
 When using commercial copper pipes and fittings, observe the following:
1 Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052 W/mk (0.035 to 0.045kal/mh°C)
Refrigerant gas pipe’s surface temperature reaches 110°C max.
Choose heat insulation materials that will withstand this temperature.
2 Be sure to insulate both the gas and liquid piping and to provide insulation dimension as below.
Pipe Dimension Heat Insulation Dimension
Gas side 3/8”(O.D. 9.5mm t0.8mm) I.D.12-15mm t10mm Min
Liquid side 1/4”(O.D. 6.4mm t0.8mm) I.D. 8-10mm t10mm Min
3 Use separate heat insulation pipes for gas and liquid refrigerant pipes.
 Required material
o Pipe size reducer (CZ-MA1P) for CS-Z50*** when connect to multi.
