(3) According to requirements by electric wiring diagram, connect wire controller to indoor
electric box. Connect indoor/outdoor connecting cable and outdoor pipe temperature probe
connecting cable to outdoor electric box. Plugs shall be firmly and reliably in place and held
tight by wire clamp.
(4) Special power supply cables must be used for the units. For FRD23-B, 250V 10A power
plug shall be used, 250V 15A plug for FRD35-B, and 250V 25A for FRD50-B. User must
select sockets corresponding to these plugs. For other models of air duct air conditioners, we
will not supply power plug and user must adopt special power lines.
(5) Units with auxiliary electric heating must connect an electric heating power cable on the
electric box (YZ3X1.5+1X1 cable for FRD125/S, RVV3X2.5 sheathed cable for FRD95, 2
YZ3X1.5+1X1 cables for FRD180, and 2 YZ3X1.5+1X1 cables for FRD260) to wiring
terminal seat on electric heating box in a corresponding manner, connect earthing line, hold
tight with wire clamp, and fix cover plate on the seat. Only turn on machine with wires
connected; otherwise short circuit can occur.
Notes:
1. For FR(D)125/S, FR(D)180/S and FR(D)260/S, check for correct rotation direction of
compressor before system installation and operation. Compared with normal operation,
reverse compressor rotation can cause high noise and small current. FR(D)180/S and
FR(D)260/S wire controller will indicate E6 (confirm no absent phase) for reverse compressor
rotation. Shutoff the unit at once, disconnect power and swap 2 any phases.
2. Indoor/outdoor connecting cable must be sheathed cable meeting state standards. Signal
lines shall be
≥
1mm
2
sheathed cable.
FR95, FR95-C power cable shall be
≥
2.5mm
2
cable (with yellow/green earthing line);
indoor/outdoor power connecting cable shall be
≥
2.5 mm
2
cable (with yellow/green earthing
line).
FRD95 power cable shall be
≥
6mm
2
cable (with yellow/green earthing line); indoor/outdoor
power connecting cable shall be
≥
2.5 mm
2
cable (with yellow/green earthing line).
FR125/S, FR125-C/S power cable shall be
≥
1.5mm
2
cable (with yellow/green earthing line);
indoor/outdoor power connecting cable shall be
≥
1.5mm
2
cable (with yellow/green earthing
line.
FRD125/S power cable shall be
≥
4mm
2
cable (with yellow/green earthing line);
indoor/outdoor power connecting cable shall be
≥
1.5mm
2
cable (with yellow/green earthing
line).
FRD71-B, FR100-B power cable (with yellow/green earthing line) and indoor/outdoor power
connecting cable shall be
≥
2.5 mm
2
cable (with yellow/green earthing line).
FRD71-B, FRD100-B indoor power cable shall be
≥
4mm
2
cable (with yellow/green
earthing line). Indoor/ outdoor power connecting cable shall be
≥
2.5mm
2
cable (with
yellow/green earthing line). Indoor and outdoor signal cables shall be
≥
1mm
2
cable.
