2.3 Equipment Description

1. The washer is front-loading and automatic. A revolving wash arm sprays the wash and rinse solutions. A 45-gpm capacity pump circulates the wash and rinse solutions, and empties the solutions during the drain cycles. The water temperature entering the washer should not be greater than 120°F. The total time for a complete cycle is 4-1/2 minutes. Special rack(s) are used to hold respirators in the washer.

2. The manufacturer’s recommendation is not to exceed 120°F. This is achieved by setting thermostat on the hot water heater to 120°F and running the water in the sink until it is hot. The temperature on the front of the washer should not read greater than noted temperature and no additional checks are necessary.
