Chromalox PD422-4 Electric Heater User Manual


 
OPERATION
1. Do not operate heater at voltages in excess of that stamped on
the heater since excess voltage will shorten heater life.
2. Always maintain a minimum of 2” of solution
above the heated portion of the element (See Figure 1, “B”
Dimension) to prevent exposure of the effective heated length. If
the heater is not properly submerged, it may overheat and shorten
heater life.
If the heater is not properly submerged, the heating
elements will overheat and could result in a fire or
damaged equipment.
3. In an electroplating operation the heaters are not under any cir-
cumstances to be placed between the electrodes and the work.
MAINTENANCE
ELECTRIC SHOCK HAZARD. Disconnect all power
before installing or servicing heater. Failure to do so
could result in personal injury or property damage.
Heater must be installed by a qualified person in
accordance with the National Electrical Code, NFPA
70.
1. Heaters should be checked periodically for coatings and corro-
sion, and cleaned if necessary.
2. Tank should be checked regularly for sediment around the end
of heater as this sediment can act as an insulator and shorten heater
life.
