specifications?
Is something blocking the air
outlet or inlet of either the
indoor or outdoor units?
Did you set the external static
pressure?
Are the refrigerant piping
length and additional
refrigerant charge noted
down?
Did you check that no wiring
connection screws were
loose?
Also review the SAFETY CONSIDERATIONS.

SELECTING INSTALLATION SITE

• In cases where the unit is installed in a space where the
humidity might exceed 86°F and RH80%, reinforce the
insulation on the unit body.
Use glass wool or polyethylene foam as insulation so that
the thickness is more than 2" and fits inside the installation
space opening.
(1) Select an installation site where the following conditions are
fulfilled and meets with your customer's approval.
• Where optimum air distribution can be ensured.
• Where nothing blocks air passage.
• Where condensate can be properly drained.
• Where the supports are strong enough to bear the
indoor unit weight.
• Where the false ceiling is not noticeably on an incline.
• Where piping between indoor and outdoor units is
possible within the allowable limit. (Refer to the
installation manual for the outdoor unit.)
• If a return-air duct is not installed, carefully select the
place and method of product installation so that air
flow into the product will not be blocked.
• The unit clearance from a combustible surface may
be 0". However, service clearance must take
precedence. A minimum of 24" in front of the unit for
service clearance is required. Additional clearance on
one side or top will be required for electrical wiring
connections. Consult all appropriate regulatory codes
prior to determining final clearances. When installing
this unit in an area that may become wet (such as crawl
spaces), elevate the unit with a sturdy, non-porous
material. In installations that may lead to physical
damage (i.e. a garage) it is advised to install a
protective barrier to prevent such damage. Always
install units such that a positive slope in condensate
line (1/4" per foot) is allowed.
If installed horizontally above a finished living space a secondary
drain pan, as required by many building codes, must be installed
under the entire unit and its condensate drain line must be routed
to a location such that the user will see the condensate discharge.

INSTALLATION LOCATION

NOTE: These air handlers are designed for indoor installation
only.
Applications where the air handler is installed and the return air
environment see humidity levels above 65% relative humidity
coupled with total external static levels above 0.5"; it is
recommended to reinforce the insulation on the unit body.
The FTQ**T product line may be installed in one of the upflow,
downflow, horizontal left or horizontal right orientations as shown
in Figures 3, 4, 5 and 6. The unit may be installed in upflow or
horizontal left orientation as shipped (refer to specific sections
for more information). Minor field modifications are necessary to
convert to downflow or horizontal right as indicated in below
sections.
