II.) Thermal Protector
The thermal protector protects your pump from
overheated water. When the spray gun trigger is
released, the pump DOES NOT stop pumping. Water is
circulated through the unloader valve and pump. The
circulating water heats up quickly. The thermal protector
discharges water when it reaches 140°F preventing
pump damage .
