Research
system as to size and amount of sprinkler lines, sprinkler heads and what length the
drops are. To determine the distance from Dropmaster to the area being serviced, a
preliminary calculation should be done to determine amount of water trapped in
system. See page 6 for water calculations.

much water as possible at the main drain and the inspectors test valve or auxiliary drain
valves before hooking up the Dropmaster to the sprinkler system.

Mini E unit requires a 120 volt 15 amp circuit with no extension cords.

Connect the ‘Dropmaster Odor and Water Eliminator’ to the main drain or any
convenient drain connection. When putting the Dropmaster in to service according to
specified procedures, it will maintain a constant 10.00 inches of mercury vacuum
pressure, which in turn will cause a siphon effect when a sprinkler head is removed; thus
allowing the sprinkler fitter the time required to replace the sprinkler head with no water
back splash or odor from the pipe.

Connect the 1” discharge hose to the drains, any outlet.
