OPERATING MANUAL FOR HEATSAN

  Page 6 

Tank Full Restart 

The tank full restart is the delay before the MRO unit starts when a tank full 
condition clears. This delay can be in minutes or in seconds. The TF Restart 
Setpoint selects seconds or minutes. 

Tank Full Override 

A timed tank full override can be initiated when the MRO unit is shut down due 
to a tank full condition. Pressing the Alarm Silence/Reset key for 3 seconds 
during a tank full condition will enable the tank full override. The RO will start 
and TF OVERRIDE 9 will show on the display. The number is the minutes 
remaining in the override timer. When the override times out, the unit will 
return to the tank full shut down condition. The TANK FULL OVERRIDE will 
divert all water to the drain, whether the water quality is good or bad coming 
into the RO. 

Pressure Fault 

If the pressure fault input becomes active (closes) and stays active for the 
delay programmed in the PF Delay Setpoint, the unit will shut down for a 
pressure fault. The display will show PRESS FAULT, the alarm lamp will flash 
and the audible alarm will sound. The pressure fault can be cleared by 
pressing the Alarm Silence/Reset key twice. 

Auto Reset 

If a pressure fault shut down occurs and the Auto Reset Setpoint is 
programmed to 0, the unit will remain shut down until manually reset. If the 
Auto Reset Setpoint is programmed to a value greater than 0, the unit will 
automatically clear the pressure fault and attempt to restart after this delay 
times out. 

Alarm Silence 

When a shut down occurs that causes the audible alarm to sound, the alarm 
can be silenced by pressing the Alarm Silence/Reset key once. The alarm will 
remain silenced for 3 minutes [180 seconds (AAMI RD62 standard)] when the 
Alarm Silence Setpoint is programmed to the factory default 3.  If the Alarm 
Silence Setpoint is programmed to a value other than 3, the alarm will 
resound after this delay times out. Pressing the Alarm Silence/Reset key will 
silence the alarm and reset this delay.
