Proper
installation
is the
responsibility
of the
installer.
Product
failure
due to improper
installation
is not
covered
under
the Warranty.
CHASSIS
INSTALLATION
Units
are shipped
without
a sleeve.
In applications
where unit is a replacement,
it is recommended
that a
Gree sleeve
be used.
These
units
can retrofit
Carrier,
General
Electric,
Amana,
Trane,
and Friedrich
sleeves/grilles
(be sure
outdoor
grille is installed
on the sleeve).
See Table 3
for details. Gree engineering
must approve
any other
retrofit application.
For competitive
retrofit applications,
be sure that the
foam
seals
(factory-installed
on
the tube
sheets)
provide a good seal between the grille and outdoor coil
tube sheets.
These
foam
seals provide
a barrier
to
separate
outdoor
coil leaving
air from mixing
with
the outdoor
incoming
air (known
as air recircula-
tion).
UNIT
DAMAGE
AND/OR
OPERATION
HAZARD
Failure
to follow
this caution
may
result
in equipment
damage
or improper
operation.
For retrofit
applications,
foam
seals
on outdoor
coil tube
sheets must
make a seal between
the coil and the grille or
loss of performance
and premature
damage
to the maior
components
can result.
