Specialized
Fittings
Specialized components
and parts should be used
for installation; otherwise it
would lead to water leakage,
electrocution, re hazards etc.
Specialized
Size of the power lines should
be large enough. Power lines
and other electric connection
lines should be replaced by
specialized cables.
When wiring of power lines is
nished, remember to install a
electric box to prevent safety
accidents.
When installation is finished,
check for connection of drain
lines, water lines and electric
lines, as incorrect connection

periodically in case that heat
exchanging effect would be
a󰀨ected.
Please do freeze protection in
winter to prevent copper tubes
from cracking.
Don’ t leave windows and
doors open for a long time
while operating the FCU. It can
decrease the FCU capacity.
Don’t blow the wind to animals
and plants directly. It can
cause a bad inuence to them.
Don’t use the FCU for other
purposes, such as drying
clothes, preserving foods, etc.
Don’t place a space heater

1. Product Introduction
1.1 Working Principle
The cold (hot) water entering the heat exchanger will do heat exchanging with air passing through the
surface of the heat exchanger to condition the air temperature and humidity. There is no (cold) hot source
for this product itself. The running mode depends on the environment temperature and the running mode of
the main unit.
Protection against hot air
Under the cooling mode, when the water temperature is too high, the fan will be stopped to avoid the
unit from blowing out hot air.
Protection against cold air
Under the heating mode, when the water temperature is too low, the fan will be stopped to avoid the unit
from blowing out cold air.
Memory function
Upon power failure, some statuses can be memorized, including: mode setting, fan speed setting, fan
swing setting, temperature setting etc.

1.3 Working Conditions
(1) The entering water temperature for cooling is suggested to be no less than 5℃,otherwise it woule lead
to condensate; the entering water temperature for heating is suggested to be not higher than 60 ℃,
otherwise it would lead to corrosion of copper tubes or abnormal noise.
(2) The suggested working environment temperature for cooling ranges 16 ～40℃and ranges 10 ～35℃
for heating. Beside, the relative humidity is or less than 80%.
(3) This product is a kind of comfort air conditioning, and is not allowed to be installed where there are
corrosive, explosive and inammable substances or smog; otherwise it would lead to operation failure,
shortened service life, ve hazard or even severe injuries. Special air conditions are required for where
mentioned above.
(4) The A-weighted sound pressure level is below 70dB.
(5) The temperature exchange e󰀩ciency and enthalpy exchange e󰀩ciency are tested under these testing
conditions as below:
yCooling capacity: air 27°C DB , 19°C WB, water temperature intake 7°C, outlet 12°C.
yHeating capacity: air 20°C DB , For the tow-row coils applicable to EU, the entering/leaving water
temperature is 45°C and 40°C; and for the four-row coils, the entering/leaving water temperature is
65°C/55°C.
yFreeze-up : air 27°C DB, 24°C WB , water temperature 6°C intake , 10°C outlet .
ySound power level according to ISO 5151. Sound pressure level are calculated at the below of air-
outlet 1m and 1m distance. The noise are tested before leaving factory.

2.2 Installation of the Rear Panel
(1) Always mount the rear panel horizontally. Due to the water tray of the unit has been adopted the both-
way drainage design, the outlet of water tray should be adjusted slightly down when installing, that is
to take the outlet of the water tray as the center of a circle, the included angle between the evaporator
and level should be 0 or more, that is good for condensing water drainage.
