GENERAL
c. Plumbing System. The plumbing system provides water for Printing
Press operation and cleanup.
Water is pumped by the auxiliary pump into the water tank through the
water inlet on the water box. The auxiliary pump has a 1/2-horsepower
115-volt motor. Water is stored in the 36-gallon water tank until it is
pumped by the main pump up to the faucet assembly. An adjustable immersion
heater at the bottom of the tank allows selection of a range of water
temperatures. The main pump has 1/8-horsepower 115-volt motor with a
rating of 14 psi.
The pressure switch controls operation of the main pump in response to
the pressure in the faucet water piping. It activates the main pump when
water pressure falls and shuts down the main pump when proper pressure is
reached. The pressure switch is adjusted by a screw +10 psi from the
standard 14 psi.
Water is pumped from the water tank to the faucet assembly and sink.
The faucet assembly controls rate of water flow.
As water drains from the sink, it flows through a hose to the water
box drain pipe and out of the Section for disposal. An angle valve is
located on the sink drain pipe to drain the faucet plumbing.
