Brantford "Ideal" Gas and Gasoline Engines - Instruction Book #272180

The bottom portion of the cooler needs to be filled only when starting; after that, all the water that is required is enough to replace evaporation. An angle valve. Is placed on the upper pipe E to regulate the quantity of water entering the cooler. A pet cock is placed on the centrifugal pump for testing the pressure of water, giving vent for drainage, etc., and the two drain plugs marked 1 and 2 must always be removed in frosty weather to drain water out of cooler, cylinder, pump, etc., as there is more damage done from the neglect of this Operation than from all other sources. When space must be economized, and on smaller sized engines we furnish a cooler with reservoir of smaller capacity which can be attached to the top of the cylinder, the principle Of the piping being the same.
