Figure 7 Liquid level identification
6.4.2 Exhaust and drainage
After the first addition of water and replacement of new water, exhaust the air in the pump to start the
use, otherwise it will damage the equipment. Exhaust method: slowly loosen the air-exhaust screw plug
of the pump (do not screw off), discharge air until water flows out, and then tighten the air-exhaust
screw plug (see Figure 8, in which only the exhaust positions of vertical pump and horizontal pump are
shown. According to customer requirements and specific type, the pump will be different, exhaust
location will also be different, and details can be seen in the pump external indicator). Note: When the
liquid in the equipment needs to be drained in winter, loosen the water-exhaust screw plug below to
drain the liquid.
