Water
supply
The inlet water pressure should be in the range of 0.1–0.7 MPa (A
reducing valve must be installed if the inlet water pressure exceeds
0.7 MPa.), and the temperature should be in the range of 1°C–
40°C.
The water should meet the following requirements:
● Non-freezing and nephelometric turbidity units (NTU): < 3
● No visible substances
● 6.5 ≤ pH value ≤ 8.5
● Total hardness (in CaCO
3
): ≤ 450 mg/L
Drainage The distance between the upper drainage of the water pump and
the cabinet installation oor should not exceed 4 meters.

Leakage circuit breakers are not recommended for the primary
route. If a leakage circuit breaker is required by the customer or by
local regulations, use the residual current circuit breaker (RCCB)
that is not sensitive to the single-phase DC pulses and transient
current pulses.
Space Requirements
● Before installation, verify that the installation environment meets the
requirements and whether reconstruction is required for routing water pipes,
cables, and ventilation pipes.
● Install the indoor unit according to the design drawing and reserve space for
maintenance. At least 1200 mm maintenance space must be reserved in front
of or at the rear of the indoor unit, and at least 600 mm maintenance space
must be reserved at the other end, as shown in Figure 4-3.
