WIRING
WARNING: Hazard of Electric Shock. Any installa-
tion involving electric heaters must be effectively
grounded in accordance with the National
Electrical Code to eliminate shock hazard.
1. Electrical wiring to heater must be installed in accordance
with the National Electrical Code or local electrical codes by a
qualified person.
2. When element wattages are not equal, heaters must not be
connected in series.
3. For single phase, apply power across two (2) black leads.
Green wire (ground) must be properly grounded.
4. For balanced 3 phase loads, three (3) heaters of the same volt-
age and wattage ratings are required. A six-step guide to
wiring connections for 3 phase delta:
OPERATION
1. Do not operate heater at voltages in excess of that stamped on
the heater since excess voltage will shorten heater life.
2. WARNING: 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 and create a fire hazard.
3. In an electroplating operation the heaters are not under any
circumstances to be placed between the electrodes and the
work.
MAINTENANCE
WARNING: Hazard of Severe Shock. Disconnect all
power to heater before servicing or replacing
heaters.
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 insulation and shorten
heater life.

Step 1: Designate one
black leadwire as “A” and
one black leadwire as “B”.
Step 2: Assign designa-
tions 1, 2, 3 to heaters.
Step 3: Connect leadwire
“A” of Heater #1 to lead-
wire “A” of Heater #2.
Step 4: Connect leadwire
“B” of Heater #1 to lead-
wire “B” of Heater #3.
Step 5: Connect leadwire
“B” of Heater #2 to lead-
wire “A” of Heater #3.
Step 6: Designate one 3
phase power line to each of
the three connections.
