PARMAIR EXIMUS JrS and JrV
When the maintenance monitor led (12) and the fan speed symbol blink simultaneously, the fan
is malfunctioning. The function may be activated when the antifreeze function is working and
the unit is slowing the intake fan down. The function also turns on when a fan malfunctions.
9.7 THERMAL SHIELD
Both of the unit’s heating elements are equipped with a resettable thermal shield. If the thermal
shield has been tripped, it can be reset by pushing the reset button. The set value of the manual
thermal shield is +70° C. The set value of the thermal shield with automatic reset function is
+40° C.
(NB! The cause of the tripping of the thermal shield with the reset function must always be
clarified.)
10. MAINTENANCE
In order to ensure the faultless performance of the Eximus Jr Unit under all conditions, it is
important to service the unit at regular intervals. Maintenance is limited in practice to cleaning
the air filters, heat exchanger, fans and internal parts. It is recommended that maintenance
operations be performed in the following order:
NB! Be sure there is no current in the unit before doing any maintenance work.
a) CLEANING THE HEAT EXCHANGER
Remove knobs and lift front cover away from unit.
Beware of hot surfaces!
Remove any dirt adhering to heat exchanger (approximately every second year) in order for it to
work efficiently. The heat exchanger can be removed from the unit by carefully withdrawing it.
NB!
Beware of the heat exchanger’s sharp edges when removing and handling it.
Wash heat exchanger in hot water, for example by using a hand-held spray.
Clean interior of unit, if necessary.
