Connection of pipe

Installation procedure

1. Connection of pipe		Joint	Nut
**The max length of connection pipe is 50m, the max fall is 30m.		Joint	Nut

The attentive matters in connection of pipe
In order to guarantee the efficiency, the	Spanner
In order to guarantee the efficiency, the
pipe should be as short as possible.			Spanner
Do not make the connection pipe distorted and deformed.			Spanner
Do not make the connection pipe distorted and deformed.
Do not let dust enter into pipe.
When bending the pipes, give the roundness as large as possible.
Both gas pipe and liquid pipe should be thermal insulated.
There should be no leakage at the flare parts.

If do not fit the center and screw the nut hard, the screw thread may be damaged, which will cause refrigerant leakage.

Pipe diameter		Fasten torque
Liquid pipe	9.52mm	32.7~39.9
Gas pipe	19.05mm	97.2~118.6

**Connection method

***Daub the refrigerant oil on the joint and the flared nut.

***When bending the pipes, give the roundness as large as possible.

***To connect the pipe, fit the center and use hand to screw the nut, then use spanner to tighten the nut, as shown in figure.

***Pay attention not to let alien matters, such as sand, get into the pipe.

2. The additional charging amount of refrigerant

The additional charging of refrigerant (R407C) should be complied with the installation manual of outdoor unit. It must use measurer to quantificationally charge. The additional charging amount must be complied with the specified amount.

Requirements: Both excessive charging and less charging of refrigerant will cause the compressor trouble. It must be complied with the specified amount.

3.Vacuumizing

Use vacuum pump to vacuumize from the stop valve of the outdoor uin.

It is strictly prohibited to use the refrigerant sealed in the outdoor unit to perform air discharging.

4.Leakage detection

Use leakage detector or soap water to check if the connected part of the connection pipe and the valve cap leak.

5.Thermal insulation treatment

The thermal insulation of connection pipe should be performed at both gas side and liquid side. In COOLING, both liquid side and gas side are in low temperature, in order to prevent dew from forming, thermal insulation should be done.

The thermal insulation material at the gas side must use the material with the heat resistant temperature over 120*.

The connected parts of indoor unit connection pipe should be thermal insulated.
