Learning Event 1
HEAT WATER IN THE TANK
In your duties, you will sometimes need to heat water in the tank. Chemicals dissolve better in hot
water, and hot decontaminating solution is more effective than cold.
To heat water in the tank, you will first need to fill the tank. The procedure for loading the tank with
water was discussed in Lesson 3.
The procedure to follow to heat the water in the tank using the M2 water heater is discussed in
subsequent paragraphs.
WARNING
If the pump unit assembly and the M2 water heater are operated in an
enclosed area, the exhausts must be vented or placed outside the enclosed
area to prevent carbon-monoxide poisoning. A mask does not protect
against carbon-monoxide fumes.
