Before Powering Up
Chromalox takes great pride in knowing that we have provided to you a product of premium quality and workman-
ship. We have taken every precaution to ensure that your equipment arrives safe and secure.
However, vibration and temperature changes during shipping can cause some components to become loose.
Additionally, throughout the life span of this product, other environmental and application conditions may have
affected the mechanical and electrical continuity of several internal components. Therefore, for your safety and
overall product performance, please take the time to familiarize yourself with the MAINTENANCE, OPERATION,
AND INSTALLATION INSTRUCTIONS technical manual that was shipped with your panel.
Since it is not uncommon for electrical wiring and mechanical connections to become slightly loosened during
shipment, we ask that you pay particular attention to section 4-5.3 Wiring and Connections:
4-5.3 WIRING AND CONNECTIONS. Check wiring and connections as follows:
a. Inspect wiring for wear, fraying, chipping, nicks, and evidence of over-
heating. Repair minor defects with a good grade of electrical tape, or
replace if needed.
b. Inspect for loose electrical and mechanical connections. Tighten or
replace defective crimp-style lugs. Re-solder loose solder connections.
Tighten or replace all loose or missing hardware.
Pre-Service Storage
If this equipment cannot be placed into service upon receipt, prevent damage caused by impact, harsh environmental
conditions, condensation or liquid ingress. Preferably store in a clean, dry, air conditioned, or ventilated building.
During storage, assemblies should be placed on a firm, level surface to prevent distortion.
Outdoor storage of indoor equipment is not recommended. The covering provided during shipment of indoor as-
semblies is NOT adequate for outdoor storage.
Cover the equipment to keep it free from dust, dirt, and corrosive elements. The covering must protect the assembly,
but permit adequate ventilation. Blocking placed between the roof of the equipment and the cover will help keep
covering material from restricting the air flow.
If the storage area is subject to humidity and significant temperature changes, energize the anti-condensation heat-
ers provided in the equipment, or add heat from a separate source to prevent condensation inside the equipment.
The internal temperature must be at least 5˚C (9˚F) above the ambient.
If storage temperatures fall below 0°C (32°F), energize the internal equipment heaters provided, or add sufficient
heat from a separate source to keep the internal temperature of the panel to at least 0°C (32°F).
In areas with high humidity, inspect the equipment regularly, and add additional heat if necessary to keep the
equipment dry.
Remove all loose packing, documents, and flammable materials before energizing heating elements.
Heat from a separate source must be removed before the equipment is put into service.
WARNING: Care must be taken that integral control power transformers are not accidentally
back-fed from the heater circuits. Disconnect primary and secondary fuses.
Summer Standby Operation
If equipment is switched off during warm periods, and they are subject to humidity and significant temperature
changes, energize the anti-condensation heaters provided in the equipment, or add heat from a separate source to
prevent condensation inside the equipment. The internal temperature must be at least 5˚C (9˚F) above the ambient.
