8. If you are working on an older style CHC(Cabinet type) it may have the push button ON
and OFF power switches, there is an upgrade available to convert this style of switch to a
standard HOA switch. To test the push button switches, verify that power passes through
the switch as the button is pressed.
9. Verify that the pump motor's amperage is within the specified FLA as shown on its motor's
rating plate, if it is, turn the power to the skid off and verify all electrical connections. A
discoloration on a wire's insulation will signal a loose connection. Make sure all
connections are tight and verify that if any wire nuts are used, their connections are secure
as well.
5.1.3 The skid's pump will not maintain power when your release the ON push button (Older
cabinet style CHC units only)
1. Verify that the OFF switch is not stuck or defective, the OFF switch is a normally Closed
switch, however if it fails the power to the pump will not remain when the ON button is
released.
2. Check to see if the vacuum switch has been rewired, if it has, a blue and brown wire will be
wire nutted together in the motor starter. If these wires are not connected with the wire nut,
contact EcoWater CHC Service for the upgrade procedure.
5.1.4 The skid's pump pops breakers, fuses, or thermal overloads frequently-
1. Verify that the pump motor's amperage is within the specified FLA as shown on its motor's
rating plate, if it is, turn the power to the skid off and verify all electrical connections. A
discoloration on a wire's insulation will signal a loose connection. Make sure all
connections are tight and verify that if any wire nuts are used, their connections are secure
as well.
2. Verify that the power coming into the skid on all three legs is the same voltage. If you have
one leg that is significantly lower, than there is a problem with the power balancing of the
three legs at the facility and you will need to bring this to the attention of the facilities
service manager. If one leg gets loaded more than the other two, it can cause a single phase
condition of the pumps motor and will cause the amperage to suddenly increase blowing
fuses and breakers.
