ƹWhen operating, the entire capacity of the cooperating indoor unit should be not larger than
150% of outdoor unit. Otherwise, it will cause the shortage of cooling (heating) capacity.
ƹA Breaker(or fuse) need to be installed in every indoor unit, and the capacity should in according
with indoor unit’s electrical parameter; all the indoor units are required to be centralized controlled by
a total Switch, this Switch can cut off the electric power supply in case of emergency. The Breaker(or
fuse) on each indoor units have the function of short circuit prevention and abnormal overload avoiding,
it should be connected in normal situation. The total switch controlling the power supply of all the
indoor units. Before clearing and maintenance job being carried out to the indoor units, it is very
important to turn off the total power supply switch.
ƹIn order to turn on the units successfully, the main power switch should be opened 8 hours
before the operation.
ƹAfter receiving the turn off signal, every indoor unit will continue to work for 20-70sec to make
use of the rest cool air or the rest heat air in the heat exchanger, while preparing for the next operation.
And this is normal.
ƹWhen the selected operating mode of the indoor unit are clash with the operating mode of the
outdoor unit, the malfunction light will blink after 5s on the indoor unit or remote controller showing
that the operation clash, then the indoor unit will stop. At this time, change the operation mode of the
indoor unit to the one that would not clash with the outdoor operating mode to make the operation
normal. The cooling mode is not clash with the dry mode, while the fan mode is not clash with any
mode.

ƹThe main disconnection device should be explained in user manual and the height should be
recommended at 0.6-1.7m. over current protection is required(UL 1995,CSA C22.2).
ƹThe cooling range of the unit is the outdoor environment temp.23-118.4 F(-5~48°C)DB, the heating range of
the unit( only for the heat pump type unit) is the outdoor environment temp. 5-80.6 F(-15~27°C)WB.

Note!
There will be lots of lampblack and dust stick on the acentric, heat exchanger and water pump in dining
room and kitchen, which would reduce the capacity of heat exchanger, lead water leakage and abnormal
operation of the water pump. The following treatment should be taken under this circumstance:
1. Ensure that the smoke trap above cooker has enough capacity to obviate lampblack to prevent the
indraft of the lampblack by the air conditioner.
2. Keep the air conditioner far from the kitchen so that the lampblack would not be indraft by the air
conditioner.

1. Install the drain hose
ƹThe diameter of the drain hose should be equal or bigger than the connection pipe’s. ( The diameter of
polythene pipe: Outer diameter 1 in (25 mm) Surface thickness ı0.06 in (1.5 mm)
ƹDrain hose should be short and drooping gradient should at less 1/100 to prevent the formation of air
bubble.
ƹIf drain hose cannot has enough drooping gradient, drain raising pipe should be added.
ƹTo prevent bent of the drain hose, the distance between hoisting stand should is 3.28 to 4.92 ft (1 to 1.5 m).

ƹUse the drain hose and clamp attached. Insert the drain hose to the drain vent, and then tighten the
clamp.
ƹEntwine the big sponge on the clamp of drain hose to insulate heat.
ƹHeat insulation should be done to indoor drain hose.

Instruction
ƹThe slant gradient of the attached drain hose should be within 3 in (75 mm) so that the drain hole doesn’t has
to endure the unnecessary outside force.
ƹPlease install the drain hose according to the following process if several drain hoses join together.
