Rinnai 22 Multi Split Type AC
INDOOR INSTALLATION
Rinnai 19 Multi Split Type Air Conditioner
NOTE : DRAINPIPE INSTALLATION
The drainpipe is used to drain water from the unit.
Improper installation may cause unit and property
damage.
CAUTION
NOTE ON PURCHASING PIPES
This installation requires a polyethylene tube
(outside diameter = 3.7-3.9cm, inside diameter
= 3.2cm), which can be obtained at your local
hardware store or fr om your dealer.
•
When using an extended drainpipe, tighten
the
indoor connection with an additional
protection tube to pr
event it from pulling
loose.
• The drainpipe should slope downward at a
gradient of at least 1/100 to prevent water
from flowing back into the air conditioner.
• To prevent the pipe f rom sagging, space
hanging wires every 1-1.5m.
• If the outlet of the drainpipe is higher than
the body’s pump joint, p
rovide a lift pipe for
the exhaust outlet of the indoor unit. The lift
pipe must be installed no higher than
75cm
from the ceiling board and distan c
e between
the unit and the lift pipe must be less t
han
30cm. Incorrect installation cou
ld cause
water to flow back into the unit and flood.
• To p revent air bubbles, keep the drain hose
level or slightly tilted up (<75mm).
