Drain Piping Work
• Drain pipe must be in downward gradient for smooth
drainage.
• Avoid installing the drain pipe in up and down slope to
prevent reversed water flow.
• During the drain pipe connection, be careful not to exert
extra force on the drain connector at indoor unit.
• The outside diameter of the drain connection at the flexible
drain hose is 20mm.
• Be sure to execute heat insulation (polyethylene foam with
thickness more than 8.0mm) on the drain piping to avoid
the condensed water dripping inside the room.
Drain Test
• Connect the main drain pipe to the flexible drain hose.
• Feed water from flexible drain hose to check the piping for
leakage.
• When the test is completed, connect the flexible drain hose
to the drain connector on the indoor unit.
Panel Installation
• The front panel can only be fitted in one direction, follow
the piping direction. (Observe the piping arrow sticker on
the front panel).
• Be sure to remove the installation template before installing
the front panel.
• Open the air intake grille by pulling back the catchers and
remove it together with the filter from panel.
• Install the front frame panel onto the indoor unit with 4
screws and tighten it completely to prevent cool air leakage.
• Connect the LED wire and air swing wire to the indoor
unit.
NOTE:
Install the front frame panel firmly to prevent cool air leakage which will cause condensation and water dripping.
