Water Quality Requirements
If the inlet water contains large granules, install a water filtering device at the inlet port to
prevent pipe blockage.

Specifications
 Water pressure ranges from 0.1 MPa to 0.7 MPa. (A
reducing valve must be installed if the inlet water pressure
exceeds 0.7 MPa.)
 Water temperature ranges from 1° C to 40° C.
 Transient flow is greater than or equal to 0.6 L/min.

The quality of supplied water must meet the requirements
listed in
 The upper drainage height of the condensate pump should
be 3.5 meters at most.
Self-drainpipe inner diameter ≥ 19 mm, self-drainage

leveling tube length ≤ 2 m.
 The hose can be used in a environment whose temperature
is higher than 85° C. (The requirement is only for the units
with a humidifier.)
 380–480 V 50 Hz or 60 Hz 3W+PE (Voltage jumpers are
used to confirm the rate voltage. The compatible voltage
jumpers include 380 V 50 Hz or 60 Hz, 400 V 50/60 Hz,
415 V 50 Hz or 60 Hz, 440 V 60 Hz, 460 V 60 Hz, and 480
V 60 Hz.)

Tolerance: rated voltage ± 10%; rated frequency ± 3 Hz
(Recommended to add a voltage regulator in the front end if
the power exceeds this range. Otherwise, smart cooling
product will generate frequency alarms and cannot run.)
Earth leakage circuit breakers are not recommended for mains.
If earth leakage circuit breakers are required by the customer or
according to local regulations, use the residual current circuit
breaker (RCCB) that is not sensitive to the single-phase DC
pulse and transient current pulse.
