Manual# I27028 7-1 Rev. 2 – 11/22/2017
7 - TROUBLESHOOTING
There are two parts to this section of the manual. The first part lists each of the fault and
warning indicators. In the second part, there are some additional detailed
troubleshooting checks.
In order to check these conditions, the R-Series unit must be turned on and operating, or
trying to operate.
The R-Series unit is wired for up to 575 VAC. The can be
enough voltage and current present at the unit to result in death
or cause severe burning. Always turn off the power before
working inside the unit. Follow standard lock-out tag-out
procedures. Only trained electricians should perform work with
the electrical parts.
The blowers inside the R-Series unit spin at a high rate of speed.
Hands may be badly hurt if put inside the blower while it is
turning. Keep hands away from the blowers while the unit is
turned on.
If this documentation does not address a specific issue, call the Technical Support
Department at Munters. Technicians are available to answer questions and assist with

The control system on this machine is set up to react to problems in two possible ways:
• A "fault" is caused by a condition which might create a danger to personnel or
damage to the machine. A fault condition lights a red indicator on the front panel
and causes the machine to shut down.
• A "warning" is caused by a condition which might make the machine run less
efficiently. A warning condition allows the machine to continue to run, but signals
that corrective action is advised.
Refer to section 5.6 for additional information on alarms and recovering from fault / warning
conditions.
