the amperage is not less than 10% than shown on
the data plate of the motor. If so, pitch of the fan
blades needs to be adjusted, call your REYMSA
Representative for assistance

Clogged nozzle(s) Check spray nozzles and clean or replace as
required
Low water level on the basin Check water level control and adjust if necessary
The flow of water through
