Soft Alarms: The following remaining errors give a 15 second audible chirp only
System Display
Problem
Resolution
The module indicated is
no longer communicat-
ing to with the system.
Ensure all modules are
connected properly to the
system and to each other.
Modules can be tested indi-
vidually by plugging in one
at a time and cycling power
to the system.
Replace any module that is
not detected when plugged
directly into the controller.
Warning: After any hard alarm, the home or facility should be disinfected. Follow the steps un-
der the “System Disinfection” heading.
Boil Water Advisory: If any failure occurs on a RMS UV system, the water must not
be used for human consumption until the system is returned to a safe operational
mode. If the water is used for human consumption during this period, the water
must be boiled (minimum 20 minutes at a full boil)
prior to
consumption.
Temperature Management Devices
Your RMS RMS system is designed to run continuously to ensure optimal disinfection. However,
during periods when no water is drawn through the system, the energy from the disinfection
process can cause the temperature of the water inside the chamber to rise. In extreme situations
elevated water temperature or the fluctuation in temperature can lower the output of the UV
lamp. In these cases, or if the elevated water temperature is a nuisance, RMS recommends one
of the following forms of temperature management devices.
Cooling Fan
Designed for use on the RMS-C systems, the fan runs continuously to cool the
water by forced convection. The long-life fan is powered independently using a
compact modular power adapter that operates from 90-265V (47-63Hz). Order
PN MOD-FAN-RMS (only fits “-C” variants and RMS-20 series).
Temperature Relief Valve (TRV)
On reaching a higher temperature, the TRV is designed to drain a small amount
of water to allow fresh, cooler water to enter the system. The TRV works without
power and comes complete with 10’ of drain line. Order PN RMS-TRV-1 for 1”
ports.
