Drain Piping - Toshiba MMD-UP0071SPH-UL Installation Manual

 Installation of wired remote
control (sold separately)
For installation of the wired remote control, follow the
Installation Manual attached with the remote control.
• Pull out the remote control wire together with the
refrigerant pipe or drain pipe.
Pass the remote control wire through upper side of
the refrigerant pipe and drain pipe.
• Do not leave the remote control at a place exposed
to the direct sunlight and near a stove.
13-EN
 Installation of wireless
remote control
(sold separately)
The signal receiving unit of indoor unit can receive a
signal by distance within approx. 23.0' (7 m).
Based upon it, determine a place where the remote
control is operated and the installation place.
• Operate the remote control, confirm that the indoor
unit receives a signal surely, and then install it.
• Keep 3.3' (1 m) or more from the devices such as
television.
(Disturbance of image or noise may generate.)
• To prevent a malfunction and reception failure of the
remote control, select a place where it is not
influenced by a fluorescent light, equipment
(Electronic whiteboard etc.) emitting infrared rays, or
direct sunlight.
• Switching the setting (A-B selection) of the wireless
remote controls and the signal receiving unit enables
two indoor units installed in a room to be respectively
operated using two wireless remote controls.

Drain piping

CAUTION CAUTION
Following the Installation Manual, perform the drain piping work so that water is properly drained, and apply a
heat insulation so as not to cause a dew drop.
Inappropriate piping work may result in water leakage in the room and wet of furniture.
• Provide the indoor drain piping with proper heat insulation.
• Provide the area where the pipe connects to the indoor unit with proper heat insulation. Improper heat insulation
will cause condensation to form.
• The drain pipe must be sloping downward (at an angle of 1/100 or more), and do not run the pipe up and down
(arched shape) or allow it to form traps. Doing so may cause abnormal sounds.
• Restrict the length of the traversing drain pipe to 65.6' (20 m) or less. For a long pipe, provide support brackets
at intervals of 4.9' - 6.6' (1.5 - 2 m) to prevent flapping.
• Install the collective piping as shown in the following figure.
• Do not provide any air vents. Otherwise, the drain water will spout, causing water to leak.
• Do not allow any force to be applied to the connection area with the drain pipe.
• A hard PVC pipe cannot be connected to the drain pipe connecting port of the indoor unit. Be absolutely sure to
use the flexible hose provided for the connections with the drain pipe connecting port.
• Adhesive agents cannot be used for the drain pipe connecting port (hard socket) of the indoor unit. Be absolutely
sure to secure the pipe using the hose bands provided. Use of an adhesive agent may damage the drain pipe
connecting port or cause water to leak.
