Do not insert the drain pipe directly in the drain ditch where toxic gases such as
sulffuric gas are produced.
Toxic gas may flow into the room.

Electric work must be made by qualified electricians according to the “Engineering
standards concerning electric equipment”, “Extension wiring regulations” and the
electric wiring work manual. Be sure to use dedicated electric circuits.
●
Make sure to use specified wires for wiring, and connect them securely. Clamp the
wires to protect the terminal connection from external force.
●
Make sure to protect the unit with the D-type grounding work.

Work procedure
Refrigerating machine oil should not be applied to the threads of union or external surface of flare. It
is because
even if the same tightening torque is applied
the oil is likely to decrease the slide friction
force on the threads and increase
in turn
the axial component force so that it could crack the flare
by the stress corrosion.
Refrigerating machine oil may be applied to the internal surface of flare only.
