ELECTRIC HEATER
FAULT
POSSIBLE CAUSE AND SYMPTOMS
SOLUTION
Low airflow rate
Measure and estimate the airflow and pressure
and compare with the specification from
customer.
Incorrect position of the Klixon
High Temperature trip
out on electric heater
Check that the Klixon, is positioned in the airflow,
relocate Klixon if necessary
Check that there is no heat transfer from the
Klixon support.
WATER LEAKS
FAULT
POSSIBLE CAUSE AND SYMPTOMS
SOLUTION
Cooling mode:
Water carried away from the coil because of
excessive airflow and speed on the coil.
Estimate the airflow rate and check the speed is
lower than 2.8 m/s
Low air pressure in the compartment due to a
high airflow rate or a high pressure drop before
the fan
Check filter
Reduce airflow rate
Water found in the
ventilation section
Check seals around the ventilation section.
Check the door seal
Check for the presence of silicone seals in the
corners of the door and at the bottom of the
refrigeration section bulkhead.
Water ingress in the
filter compartment
Water ingress through a leaking fresh air hood
or when running 100% fresh air
Check the seals and flanges in the fresh air hood
Reduce the airflow rate if necessary
DC50 & DS50
FAULT
POSSIBLE CAUSE AND SYMPTOMS
SOLUTION
DC50: Nothing is
written on the screen
but it’s enlightened
Problem of addressing pLAN on the DC50
Press on the three right-
hand side’s buttons at
the same time during a few seconds then

(Confer DC addressing procedure)
DS50: Nothing is
written on the screen
but it’s enlightened
Idem
Press on the three right-
hand side’s buttons at
the same time during a few seconds then

an
option
disappeared
Possible problem of units' configuration
Check the instructions from 3811 to 3833 and
reconfigure options if necessary.
DS50 & DC50: the
message “No Link”
appears
Problem of addresses’ recognition
Disconnect the DS50 from the unit and then
reconnect it.
All the units are extinct Problem BM50 pLAN addressing
Disconnect then re-plug; disconnect each unit
from the others then change all the pLAN
addresses
