REFIT DRAIN HOSE FROM THE RIGHT TO THE LEFT SIDE
If drain hose needs to be refitted from the original
position (right side) to left side of the indoor unit,
careful handling is very necessary.
Refitting method: remove the drain hose from
original position, without breaking hose. Unplug
the plug at the left side. Apply water-resistant glue
to fit the drain hose and the fitting before securing
it.
Apply water-resistant glue onto the plug and fit it
back into the condensate connection at right side.
NOTES: May use some sort of clamp to double secure connections.

HANG INDOOR UNIT
Run copper set/wire cables/drain hose through the
wall hole and hang the indoor unit onto the
mounting plate (place the hook on the mounting
plate into the hanging rib at rear side of plastic
casing).
Snap the plastic casing bottom into the mounting
plate, gently .
To drain the condensate easily, the drain hose should be inclined downward (pitched towards drain direction
1/4" per foot).
Figures below from the 2nd to 5th show some incorrect practices.
Drain hose may be extended using the hose coming with the installation list.
SHAPE THE DRAIN HOSE
STUFF AND SEAL THE HOLE FOR COPPER LINE SET/WIRE CABLE/DRAIN HOSE
* Use putty to seal the wall hole.
* Use clamp (pipe fastener) to secure the pipe at specified position.

(Optional)
Strongly suggest to install the outdoor unit above the ground either on platform or brackets as shown below.
Heat pump unit must be lift up from ground level, since condensate must be drained out of the drain pan in
condensing unit; othewise,
condensate may ice up causing damage to the condensing unit.
Suggest to use YMGI-provided brackets and condensate drainage fitting accessories.

* If pipes need to come out of the rear side (facing
the front of indoor unit) of the indoor unit, no need
to snap off anything.
* If pipes need to be rerouted to a different direction
from the one preset at factory (towards left side, if
facing the front cover of indoor unit), lay down the
indoor unit on soft cushion or foam. Don't rub the
plastic casing.
* In order to keep from pipe damage, need to bend
the copper tubing set gently and slowly (finish
bending no less than 10 seconds/90 degree), by
holding at the root of the original 90 degree bend
nicely and firmly. Don't rub two copper lines during
bending. Better to cut off the insulation and bend
the two pipes one by one, not two together.
PREPARE INDOOR UNIT- COPPER LINE SET/DRAIN HOSE
INSTALL DRAIN PIPE AT INDOOR
The drain hose must be placed beneath the copper
pipes and MUST NOT be hunched or bended
sharply.
Do not pull the drain hose too hard, otherwise it
may get broken.
Before passing drain hose through the hold, wrap
with insulation to keep from possible damage.
The copper pipe and the drain hose must be
wrapped by piping wrap.
Insulation pad should be used where the pipe
contacts the wall.
