Lo Hi
Use a vacuum pump, gauge manifold and hoses exclusively for R410A.
(1) Remove both valve shaft caps of the 2 and 3-way valves.
(2) Remove the service port cap of the 3-way valve.
(3) Connect the gauge manifold hose to the service port and the vacuum
pump.
Be sure that the hose end to be connected to the service port has a
valve core pusher.
(4) Open the gauge manifold low-pressure valve(Lo) and operate the
vacuum pump for 10-15 minutes.
Make sure the compound gauge reads -0.1 MPa(-76 cmHg)(-30
in.Hg).
(5) Close the gauge manifold valve.
(6) Turn off the vacuum pump.
Leave as it for 1-2 minutes and make sure the needle of the com-
pound gauge does not go back.
(7) Open the 2-way valve 90° counterclockwise by turning the hexagon
wrench. Close it after 5 second, and check for gas leakage.*
(8) Disconnect the gauge manifold hose from the service port.
(9) Fully open the 2-way valve with hexagon wrench.
(10) Fully open the 3-way valve with hexagon wrench.
(11) Firmly tighten the service port cap and both valve shaft caps with a
torque wrench at the specied tightening torque.
* Check the pipe connections for gas leak using a leakage detector or
soapy water. Regarding leakage detector, use high-sensitivity type de-
signed specially for R410A.

5 OUTDOOR UNIT INSTALLATION
Connectingthedrainhose
In the heating mode, the outdoor unit discharges water due to defrosting from its
drain hole. Perform drain work if water drops are a problem.
(1) Insert the base pan cap and the drain hose adapter into the drain holes on the
bottom of the outdoor unit.
(2) Connect commercial drain hose to the drain hose adapter.
Notes:
• In very cold areas where the water in the drain hose could freeze, do not use the
base pan cap, the drain hose adapter and a drain hose with the outdoor unit.

Connectingthepipes
Connect the pipes for the indoor unit rst and then for the outdoor unit.
For indoor unit, remove sealing cap from the pipe end.
(1) Tighten the are nuts by hand for the
rst 3-4 turns.
(2) Use a spanner and torque wrench to
tighten up the pipes.
• Do not over tighten the pipes. It
may be deformed or damaged.
(3) Apply the accompanying insulation
to pipe joints to prevent condensa-
tion.
