(14). During installation, attach the refrigerant piping securely before running the compressor. If the compressor is not attached and the stop valve is open during pump-down, air will be sucked in when the compressor is run, causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.

.2.4 Connecting the Pipe at the Outdoor Side Unit connector. The tightening method is the same as that as at the indoor side. .2.5 Checking the Pipe Connections for Gas Leaking For both indoor and outdoor unit side, check the joints for gas leaking by the use of a gas leakage detector without fail when the pipes Fig.13...
If the outdoor unit is installed higher than the indoor unit (See Fig.16) (1). Taping should be done from lower to the upper part. (2). All pipes are bound and taped together and also should be trapped to prevent water from returning to the room. (3).

(7). Slightly open the liquid valve and let some refrigerant go to the connection pipe to balance the pressure inside and outside of the connection pipe, so that air will not come into the connection pipe when removing the hose. Note that the gas and liquid valve can be opened fully only after the manifold valve assembly is removed.
5.4 Installation of the Drain Hose 5 .4.1 Installationof Drain Piping (1). Keep piping as short as possible and slope it downwards at a gradient of at least 1/100 so that air may not remain trapped inside the pipe. (2). Keep pipe size equal to or greater than that of the connecting pipe. (3).
