Preparing the Enclosure
Determine the location of the heat exchanger on your enclosure.
1.
Be sure the weight of the heat exchanger will not cause the enclosure to become unbalanced causing
bodily harm or injury. For units mounted on enclosure doors, be sure the hinges will support the weight
of the unit. Refer to system specifications for model weights.
2.
Use the cutout template, or drawing, as a reference to make an opening in the enclosure surface for intake and
exhaust air, along with the holes for the mounting hardware and electrical connection. Cutout requirements
vary with models. Be sure that the heat exchanger will be mounted level and air flow will not be restricted
by components in the enclosure or the surrounding ambient.
3.
Test fit the heat exchanger on the enclosure to ensure that all mounting holes are aligned.
4.
Remove the heat exchanger from the enclosure and apply the gasket as shown on the gasket diagram.
Be careful not to stretch or tear the gasket material when removing the backing.
5.
After the gasket material has been installed, mount the heat exchanger to the enclosure using the
hardware provided with your system. Check to be sure all mounting hardware is tightened securely and
the gasket material is in place and compressed to approximately ½ the original thickness to
maintain enclosure integrity.
6.
Connect power to the unit from a properly grounded power supply of sufficient capacity. The controller
will then begin an approximate 90 second self-diagnostic where it will check the sensor, fan and heater
operation. Note: Heat does not function with 48 VDC power supply only and will alarm. This alarm will
auto reset at the end of the diagnostic sequence.
Controller Program Settings
Note: At start up the controller will perform a self-diagnostic of all functions for 90 seconds then it will go into
normal operation. Operation will be based on sensed temperature and controller settings.
The digital controller has many function settings that may or may not be required for application. However,
the controller has been set at the factory with typical default settings for immediate system operation. Please
review the following default settings.
