C) It is prohibited to change the set point of protection device.
It may cause fire accident.
D) It is prohibited to bypass the protection device when starting the chiller
It will cause fire accident.
E) Ventilation is required during chiller servicing.
Refrigerant leakage will reduce the concentration of oxygen. So it may cause suffocation
when ventilation is insufficient.
4.4 Notes for Relief Valve
Each system will be equipped with a relief valve on the top of the evaporator and oil separator (No
relief valve on the condenser because it connects the oil separator) in order to release the
pressure of vessel when it is too high.
The relief valve installation for double valve design, adjust the tee globe valve stem so that when a
valve is under repair, the other valve can still work. the specific structure is shown as below.
Note: When the tee globe valve stem is the shortest,1# relief valve is open, When the stem is the
longest,2# relief valve is open.

If local regulations required, so in the safety valve to connect one emptying pipe to the outdoor
(Daikin advices that customers installation emptying pipe). Refer to below; the connected pipe of
relief valve must use flexible connectors.
