Connect The Drain Pipe - Carrier 40MB*C Installation Instructions Manual

2) Be sure to insulate both the gas and liquid piping. Use
separate thermaJ insuJation pipes for gas and liquid
refrigerant pipes. See the figure below.

4.1 Installation of drain piping
Install the drain piping as shown in the figure below and take
measures against condensation. Improperly rigged piping could
lead to leaks and eventually wet furniture and belongings.

For local insulation, be sure to insulate local piping
all the way into the pipe connections inside the unit.
Exposed piping may cause condensation or may
cause burns when touched.
Make sure that no oil remains on plastic parts of the
decoration panel (optional equipment).
Oil may cause degradation and damage to plastic
parts.

install the drain pipes,
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.
Keep pipe size equal to or greater than that of the connecting
pipe (PVC pipe, nominal diameter 0.8in/2Omm in, outside
diameter 1in/25mm).
Push the drain hose as far as possible over the drain socket,
and tighten the metal clamp securely.

4 Insulation (field supply)
Insulate the drain hose inside the building.
If the drain hose cannot be sufficiently set on a slope, fit the
hose with drain raising piping (field supply).
Make sure that heat insulation work is executed on the
following 2 spots to prevent any possible water leakage due
to dew condensation.
1 Indoordrain pipe.
2 Drain socket.
