Water Pipe or Hose Connection
WARNING: Before plugging in the unit, connect the water line to the
unit. To avoid electrical shock, make sure that there is no water
splashed onto the electrical box or the power cord.
Office Pro W20 unit has two female 1/2 inch NPT (National Pipe Thread)
connectors for water connections.
Optional water hose kit with water pressure up to 150 psi (1,034 kPa) is available.
Connecting Water Pipes
1. Remove the caps from the NPT connectors on the right side panel of the unit.
Note: Small residues of water may drip from the NPT connectors when the
caps are first removed.
2. Connect the water pipes to the NPT connectors.
Note: The supplied garden hose adapters are not required.
CAUTION: Use two proper sized wrenches. Hold the wrench A
tightly so that the unit is not deformed. Apply a Teflon tape to the
thread for a good seal.
