Do not apply force to the valve lid.

Using a wrench on the valve lid or body may cause refrigerant to leak.

• When using the low outdoor temperature heating mode, the pressure on the low pressure side might drop,

so the flare nut on the stop valve should be sealed completely with silicon sealant or the like in order to

prevent frost from forming on it (both gas and liquid sides). (Refer to Fig. 12)
