3.2 Voltage Conversion
Warning: The Model EP- I Econo Pump is shipped in its 120 V or 220 V
version. To operate at other voltages, refer to the procedure below. Failure
to follow this procedure may result in damage to the unit and invalida-
tion of the warranty.
Prior to connecting the power cord to the power entry module and wall
outlet, verify that the voltage indicated on the power entry module matches
your line voltage. If it does not, use the following procedure to make the
conversion. Refer to Figure 3.2.
1.
Disconnect the power cord from the unit.
2.
Remove the fuse drawer with a small-blade screwdriver or similar tool.
3.
Pull the fuse holder out of the fuse drawer and, if necessary, replace the
fuses with ones having the correct current rating. Use 0.50 A fuses for 100
V and 120 V operation; 0.25 A fuses for 220 V and 240 V operation.
Rotate the voltage selector through the window in the fuse drawer until
the proper voltage shows.
4.
Reinsert the fuse drawer into the power entry module, with the locking
tab to the left. The voltage indicator will read right-side-up if the draw-
er is oriented correctly. Press gently until it snaps into place.
5.
Insert the power cord plug into the power entry module. Plug the powe
cord into a properly grounded outlet.
