4.6 Drain Installation
A drain system of adequate capacity is essential to the machine performance. Ideally the water
should empty through a 4 inch vented pipe directly into a sump or floor drain. See figure 4.11 on
25.
A flexible connection must be made to a vented drain system to prevent an airlock or siphon
effect. If proper drain size is not available or practical, a surge tank is required. A surge tank in
conjunction with a sump pump should be used when gravity drainage is not possible, such as in
below-ground-level installations.
Before any deviation from specified installation procedures is attempted, the customer or installer
should contact the manufacturer. Increasing the drain hose length, installing elbows, or causing
bends will decrease drain flow rate and increase drain time, impairing machine performance. If
the drain arrangement is inadequate, the machine will not extract and will not discharge water
properly.

4.7 Electrical Installation
The AC drive requires a clean power supply free from voltage spikes and surges. A voltage mon-
itor should be used to check incoming power. The customers local power company may provide
such a monitor.
The AC drive provides for an internal circuit breaker. A separate circuit breaker governs the con-
trol circuit.
If input voltage measures above 230V for a 200V class drive or above 460V for a 400V class drive,
either ask the power company if their representative can lower the voltage or install a bucking
transformer kit available from the manufacturer. Voltages above 250V and 490V require additional
measures. Contact the distributor or the manufacturer for assistance.
Note: For single phase operation, connect input power to R and S, leaving the T terminal open.
Note: Do not use phase adders (roto-phase) on inverter driven equipment!
