Tube insulator (not supplied)
Heat resistant 248°F (120°C) or
above
Flare union
Flare nut
Unit side
Insulated tubes
Drain hose
Clamp
N OT E
Do not wind the armoring tape too tightly since this will
decrease the heat insulation effect. Also ensure that the
condensation drain hose splits away from the bundle and drips
clear of the unit and the tubing.
WARNING
If the exterior of the outdoor unit
valves has been finished with a
square duct covering, make sure you
allow sufficient space to access the
valves and to allow the panels to be
attached and removed.
Taping the flare nuts
Wind the white insulation tape around the fl are nuts at the gas
tube connections. Then cover up the tubing connections with
the fl are insulator, and fi ll the gap at the union with the supplied
black insulation tape. Finally, fasten the insulator at both ends
with the supplied vinyl clamps. (Fig. 5-8)
Insulation material
The material used for insulation must have good insulation
characteristics, be easy to use, be age resistant, and must not
easily absorb moisture.
WARNING
After a tube has been insulated,
never try to bend it into a narrow
curve because it can cause the tube
to break or crack.
Never grasp the drain or refrigerant
connecting outlets when moving the
unit.
5-4. Taping the Tubes
(1) At this time, the refrigerant tubes (and electrical wiring if
local codes permit) should be taped together with armoring
tape in 1 bundle. To prevent condensation from overflowing
the drain pan, keep the drain hose separate from the
refrigerant tubing.
(2) Wrap the armoring tape from the bottom of the outdoor unit
to the top of the tubing where it enters the wall. As you wrap
the tubing, overlap half of each previous tape turn.
(3) Clamp the tubing bundle to the wall, using 1 clamp approx.
each meter. (Fig. 5-9)
Apply putty here
Tubing
5-5. Finishing the Installation
After fi nishing insulating and taping over the tubing, use sealing
putty to seal off the hole in the wall to prevent rain and draft
from entering. (Fig. 5-10)
Confirm the “Checkpoint” under the section “8. PRECAUTIONS ON TEST RUN” after installation of indoor and outdoor units, panels
and electrical wiring.
