lnstall
the indoor unit on
a wall
that will be
able to
hold its own weight,
this will ensure
that
it operates
more
quietly.
(See
page
1 7 for further
instructions about

installstion.)
o
lnstall the outdoor unit
on a

discharge and

noise will not
be bothersome
to surrounding

(See
page
17 for
further
instructions
about indoor

o
Do
not
place
any obstacles
in front of
the air
discharge of
the outdoor unit.
This will cause
damage
to the compressor

motor and
will cause these components
to be
noisier.
(See
page
16 for further
instructions on
unit
clearances.)
The
fault
protector
device
might shut down
unit
for the following
reasons:
Stopping
the unit and
immediately restarting
it or
changing
modes
without waiting 3
minutes
for
time delay.
Plugging the
unit into the
power
source and
immediately starting
without 20 seconds
time
delay.
lf all operations
have stopped due
to the fault
protector, press"ON/OFF"button
to reset the
unit.
Set timer again
if it has been cancelled.
After using the unit
for an extended
period
of time,
the unit should be
inspected
for the
following
items:
o
Overheating of
the
power
supply
cord or
plug.
o
Abnormal operating sound
or unit
vibrations,
o
Water leaking
from the unit excessively,
o
Indoor unit cabinet becoming
electrified.
p
lf any of theses symptoms
occurs,
call a
qualified
service technician
immediately.
It is recommended
that a detailed
inspection be made
by a
qualifed
technician afbr 3
years
of
operation,
even
if the above symptoms
do not occur.
At the beginning
of
HEATING
operation,
This is to allow
the indoor coil to
raise in
there is a 2-5
minute delay on the
indoor fan
temperature
for
proper
operation.
In HEATING
operation the appliance
will
defrost
the outdoor
coil automatically
to raise
efficiency.
This
procedure
usually
lasts 2-10
minutes. During defrost
mode,the
indoor fan
stops operation.
After defrost
is complete,
it returns to the
HEATING mode automatically.
It may be difficult
to raise the
indoor temperature
when outdoor
temperature are
very low
(30'F)
this is due to
nature of heat
pumps
and their loss
in efficiency as outdoor
temperatu
res decrease.

r
Decide
on a location for the access hole
according to the location of the unit.
r
Drill a 2.5 inch hloe, making
sure that there is a tilt downward of
a 114

proper
drainage is maintained for the
condensate drain line.
(lf you
are not using rear access for the refrigeration
lines and wiring, the hole
does
not
need to be as large.)

lt is recommended that a wall
sleeve of some sort
(i.e.

The refrigeration

can be
routed
to the outdoor unit
in a number of ways
(left
or right from the back of the
unit), by using the cut-out access
pieces
on the casing of

When installing the refngeration lines
at

off the indoor unit casing.
e
Afterconnecting refrigeraton lines
(see
directions below), install the condensate drain line
(see page
21+24for detailed
instructions on connecting condensate drain line). Then connect all wiring
(see
pages
25-27
for
detailed
instructions
on
wiring).After all connections are
made,
bundle the
refrigeration lines, wiring,
and
condensate drain line together using a
thermal insulation and vinyl/duct tape
Refrigeration lines insulation:
o
lt is important that
both
the liquid
and suction
refrigeration lines are individuallv insulated to ensure
that they do no sweat and also to maintain
proper
unit
capacities. This is necessary since the refrigeration is
metered from
the outdoor unit and
will
produce
condensation on both
refrigeration
lines if not
proper
insulated.

r
lnsulation material should be a
polythene
foam that is approximately a 114
inch wall thickness.

1. lnstall
the outdoor unit
o
Outdoor unit
must be mounted on
a solid,
level foundation.
lf
possible,
affix unit using bolts
to the
foundation.
o
lf installing on a
wall
or
structure, be sure
that construction
of the wall or structure
can support the
weight of the unit
and
that
consideration
is
given
to the integrity of
the construction. Since
the unit can
vibrate during operation,movement
of
sound of
the unit should be
considered
when installing the unit.
o
Since
the unit discharges
air during operation,
plants
or other
obstruction should
be free and clear
of the unit
to
ensure
proper
operation.
.
Owners
should be
advised to avoid
lawn mowers or other
machinery discharge
toward the unit,
as debris can damage
the finned coil surfaces and reduce effciency
of the unit.
2. Outdoor
unit
refrigeration line connection
o
Remove
the valve caps at
the outdoor unit
where refrigeration
tubing will be connected.
o
Connect
the refrigeration tubing
using flaring techniques
described earlier
in the
indoor unit installation.
Be sure to use
required torque.
f
Atteniton
o
A baffle
is needed when
installation is in locations
near the sea or areas
with strong
winds.
.
Be sure that unit
airflow is not obstructed
in any
way
or
that reciculation
of discharge air
does not occur.

to 500
microns or
less for a
minimum
of
30 minutes' Close
the valves

800 microns.
3.
lf a vacuum
of 500
microns cannot
be obtained,
or
if it rises above
800
microns over
the 15
minute
period,
discontinue
evacuation,
pressurize
the system
with

look
for leaks. Repair
any
leaks that are
found and

HOW
TO
INSTALL
DRAIN
ACCESSORIES
There
will
be sone water
dripping
from
the
condenser
when
the heat
pump
is
working
during
the heating
mode.
Two
drain
caps,
a drain
elbow with
rubber
collar
and a
plastic
hose
(5/8"
x
6") are
supplied for
user if
choice.
INSTALLATION
STEPS
(1
)
Observe the
drainage
flow
of the
three drain
holes
on the
base while
pouring
water into
the
condensing
unit
evenly
around
the condenser. (Figure
1)
(2)
Connect
the drain
elbow
and the
plastic
hose.
(Figure
2)
(3)
Insert
the
drain
elbow
connected
with the
drain hose
into
the hole
which
has
the largest
drainage
flow
and
rohte
it
to the wall
side
of the
building in
order to make
the
drainage
flow
against
the wall.
The
other two holes
of the base
should
be
plugged
by
using the
two
drain caps.(Figure)
NOTE:
lf
the drain
hole inserted
with
the
drain elbow
is not
at the
desired location,
adjust the
level
of the
condensing
uint
slightly,
and then reinstall
the accessories
according
to the
above steps.
