Before You Install
Immediately after receiving your MaxPac I, II, III or IP Series Controller, visually inspect the shipment packag-
ing and record any damage on the shipping documents. Unpack the controller and carefully inspect for obvi-
ous damage due to shipment. If any damage has occurred, YOU must file a claim with the carrier company,
since the carrier company will not accept a claim from the shipper (Chromalox).
Be sure to check the model number and verify that you have received the correct Model of controller.
If the controller is not installed and placed into operation immediately, it should be stored in a cool, dry envi-
ronment. Temperature extremes and excessive moisture can damage the controller.
Before choosing a location in which to mount your MaxPac, please consider the following:
Temperature
When mounting the SCR unit in a control panel, attention should be paid to the enclosure tempera-
ture. The SCR is rated to perform at its nameplate current rating in temperatures up to 50˚C (122˚F).
Ensure that adequate ventilation is provided or some other method of maintaining the correct cabi-
net temperature is used.
Cleanliness
Careful attention must be paid in areas subjected to airborne particles. The efficiency of the heat
sinks relies on their conducting surfaces being maintained in a clean manner. (See the Maintenance
Section.)
Dampness
High humidity or hosing down a unit should be avoided.
Clearance
Choose a location that will provide adequate spacing around the unit when mounted. This will en-
sure proper air flow necessary to cool the device.
WARNING
Hazardous Voltage: Disconnect and lockout power before in-
stalling or servicing. Failure to comply could result in per-
sonal injury or equipment damage.
