(2) Exhaust Air
After adding water for the first time or replacing water, exhaust the air in the water pump
to start use, otherwise the equipment will be damaged. The exhaust method is as follows
：
Method 1: Under the state of shutting down, after adding water, remove the water outlet
from the laser circuit (OUTLET L) and connect the water pipe, drain for 2 minutes, and
then install it firmly.
Method 2
：
Open the water supply inlet, after starting the machine (water flows),
repeatedly press and fold the water pipe several times to drain the air from the pipe.
Method 3: Loosen the air exhaust plug of the water pump (do not unscrew), and air is
discharged until water flows out, and then tighten the air exhaust plug
(See below diagram, only the exhaust position of the horizontal pump is shown.
According to customer requirements and specific models, the pump will be different, and
the exhaust position will also be different. For the specific situation, see the external
mark of the pump).
8.Test-run Check.
(1) Check whether the pipeline connection is correct, and there must be no bubbling or
water leakage;
(2) Check whether the inlet and outlet water ball valves are open and the drain valve is
closed;
(3) Check the liquid level of the water tank;
(4) Confirm that the electrical wiring of the equipment is connected correctly;
(5) Confirm whether the equipment is grounded.
