CAUTION
If the exterior of the outdoor unit
valves has been finished with a
square duct covering, make sure
you allow sufficient space to use the
valves and to allow the panels to be
attached and removed.
Taping the flare nuts
Wind the white insulation tape around the flare nuts at the gas
tube connections. Then cover up the tubing connections with
the flare insulator, and fill the gap at the union with the supplied
black insulation tape. Finally, fasten the insulator at both ends
with the supplied vinyl clamps.

Never grasp the drain or refrigerant connecting outlets
when moving the unit.
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.
Be sure to use the heat-resistant insulator corresponding to the
gas tube of 120 °C or above and other tubes of 80 °C or above.
CAUTION
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.
