Please note: If you are drilling the hole above
ground floor level, please ensure while the holes
are drilled the outside area is supervised, until
drilling has been completed.
INTAKE AND OUTLET AIR HOLES, FRESH AIR
HOLE AND CONDENSATE DRAIN HOLE
This operation should be carried out using the
proper tools (diamond tip or core borer's drills with
high twisting torque and adjustable rotation
speed).
Fasten the template to the wall taking care to
check the distance from the floor or ceiling.
Keep it horizontal by using a level.
Use a pilot drill to mark the centre of each
core hole to be drilled, and then use a
Ø6-3/8" core boring head to drill the two
holes for intake and outlet the air.
Use a pilot drill to mark the centre of the core
hole to be drilled, and then use a Ø2-1/8"
core boring head to drill the hole for fresh air.
Use a pilot drill to mark the centre of the core
hole to be drilled, and then use a Ø1-1/4"
core boring head to drill the hole for
condensate drain
All holes should be drilled in one operation.
For detail holes sizing and dimension for the
holes, please refer to the template on page
22.
It is recommended that the holes must have a
slightly downward slope of 3-5 degree to prevent
any backflow of water in the pipes.

OWNER'S MANUAL
DRAINAGE HOLE (P13)
This unit has two alternative drainage methods to
manage condensate. Before installing the unit,
choose the most suitable method for your
application. There are 2 drain connections on the
unit, one is vertical to the floor which is named "A"
and the other one is horizontal to the floor which is
named "B" as shown in P13.
Method "A": Employing this method allows the
condensate to drain to the outdoors. Begin by
drilling a hole through the wall measuring Ø1-1/4"
in the position shown on the paper template.
Drainage occurs by gravity, thus it is essential to
have a minimum downward slope of at least 3
degrees throughout the drain line's length.
Connect the drain pipe (from soft terminal) to the
unit (hole "A") after unplugging the black rubber
cap (see picture P13). Note: If method "A" is
used, do not unplug the black rubber cap for
drainage hole "B".
Method "B":
external floor drain, water tank, or sump pump.
Unplug the black rubber cap of system "B" (see
picture P13), then connect the drain pipe (from
soft terminal) to the unit hole "B" after unplugging
the black rubber cap. Place the hard terminal into
a water tank, floor drain, or sump pump. Note: If
system "B" is used, do not unplug the black rubber
cap for drainage hole "A"
