A. Having circuit breaker and power switch in "off" position, make
sure proper voltage supplied matches voltage of control panel and
elements.
B. Adjust controlling thermostat in terminal housing to a 50°F read-
ing. Increase setting until thermostat switch just "clicks". This
setting is to be used for initial heater checkout.
C. Turn circuit breaker to "on" and note green power light coming
on. Turn on power switch and note first amber light will come on,
and then subsequent amber light(s) as explained in Section.
D. Observe control panel as heater goes through several heating
cycles. A cycle is determined when all amber lights are off. Cycle
interval can vary widely depending on amount of oil in tank.
However, the thermostat has been set to keep the cycle time to a
minimum.
CAUTION: Hazard of electric shock. Any installation involving
electric must be grounded to earth to eliminate shock hazard.
1. A safe maximum temperature limit on control cabinet compo-
nents is 125°F. Choose a mounting location not in direct sunlight
or exposed to any other source of excessive heat. If the panel must
be mounted in direct sun, a sun shield must be employed.
2. Install proper control and power wiring to control center as per
Figure J. Power lines are to be sized for the particular heater load.
Double check to insure proper grounding procedures have been
followed for heaters and control panel.
3. Available inside control panel are connections A and A1 which
provide for an over-temperature alarm; such as, horn, bell, etc., to
be mounted remotely as required. These terminals are rated at
50VA, 120V.
4. Electrical
A. CAUTION: Hazard of severe shock. Make sure circuit
breaker and panel switch are in "off" position.
B. Make knockouts in control cabinet which are desired for final
wiring installation.
C. Connect leads from riser(s) to identified terminals shown on
Figure J.
D. TEMPORARY WIRING TO SIMULATE ACTIVATION OF
CONTROL CIRCUIT.
1. Jumper terminals S to S
2. Connect overtemperature control leads to terminals 5, 6, 7
or 8 as shown on Figure J.
3. Connect green ground wire lead from riser(s) to grounding
lug in control box and from control box to a suitable
ground.
4. Connect power cable of proper voltage to input of control
box.
5. Secure control box door, then place circuit breaker in "on"
position and energize heater with panel switch. Start with
45 second time interval and increase until a definite rise in
temperature on each heater tube can be felt with the bare
hand. NOTE: Adjustable time delay(s) in multi-stage units
have been preset at factory to provide steps for energizing
individual circuits.
6. Observe green light (which indicates "power") when clos-
ing circuit breaker, first amber light with panel switch "on"
and subsequent amber light(s) (if any) at approximately 15
second intervals.
7. Have qualified electrician, using an amprobe, check amper-
age in individual heater leads to insure uniform amperage.
8. Turn circuit breaker to "off" position and remove tempo-
rary jumper from terminals Sand S

E. Turn off circuit breaker and power switch, then re-set thermostat
to desired setting for normal operation. The thermostat contains a
factory adjusted stop which prevents settings above 150°F.
F. If low temperature alarm feature is provided, set this control 10°
to 15°F below the control thermostat setting.
G. Installation of terminal housing lid and gasket (with proper gasket
sealant) completes the check-out procedure.
H. If any difficulties are encountered during the installation and
check-out, call your local Chromalox Representative or
Chromalox Product Service.
