WARNING: COMPRESSED AIR COULD CAUSE DEATH, BLINDNESS
OR INJURY
1. Do not operate at compressed air pressures above 150 psig (10.3 Bar).
2. Do not operate at line temperatures above 110°F (43°C).
3. Avoid direct contact with compressed air.
4. Do not direct compressed air at any person.
5. When using compressed air, wear safety glasses with side shields.
Introduction
A Panel Guard is designed to use ltered compressed air to cool industrial control cabinets without the use of any
refrigerants. Hot air in the cabinet is vented to the surroundings through a built in relief valve in the Panel Guard.
The Panel Guard uses a xed mechanical thermostat (non-adjustable) to maintain cabinet temperature within the
desired range.
Compressed Air Supply
The compressed air supply must be ltered to remove water and dirt using a 5 micron or smaller lter. Failure
to use a lter may cause clogging (and freezing) of the compressed air paths inside the Vortec product. Filter
recommendations are given in Table 1.
Filter elements must be changed on a regular basis. Frequency of change is determined by the condition of the
compressed air supply. Filters should be installed in the compressed air supply line as close as possible to the
Vortec product.
The appropriate size of compressed air supply line should be selected to ensure optimal performance of the Vortec
product. Please refer to Table 2 to determine what supply line size is recommended for your application. Contact
Vortec at 1-800- 441-7475 for further assistance.
Installation
To maintain the Type 4 rating, the Panel Guard must be installed in a vertical orientation on a at horizontal surface
of a Type 4 rated enclosure (see Panel Guard Assembly).
Installation procedures:
1. Cut a 1-15/16” (1-1/2” knockout size) hole in the enclosure.
2. Insert Panel Guard into cut-out.
3. Tightly thread locknut onto the Panel Guard.
4. Perforate the ducting kit with several 1/8” holes and secure to interior of enclosure.
5. Attach the ducting kit to cold outlet of Panel Guard.
6. Connect compressed air lter to Panel Guard. Install the compressed air lter as close as possible to the Panel
Guard, in a location where the temperature does not exceed 125 ° F (52 ° C).
7. Connect compressed air supply to lter.
GENERAL SAFETY CONSIDERATIONS

Operation
Operate the Panel Guard at 90 to 100 psig (6.2 to 6.9 bar) compressed air pressure. Do not operate at pressures
above 150 psig (10.3 bar). Operation at pressures less than 90 psig (6.2 bar) and above 100 psig (6.9 bar) will
effect the operation. When properly sized for the application, the Panel Guard will maintain the internal enclosure
temperature between 75-100°F (24-38°C). Enclosure temperatures can momentarily reach 125°F (52°C) during
initial start-up and after long periods of inactivity. Variations in heat load and compressed air conditions can effect
thermostat operation. The mechanical thermostat will regulate an internal valve to minimize compressed air usage
and maintain enclosure temperatures within the range specied. In some applications, the Panel Guard may run
continuously at lower air usage with the benet of always keeping the enclosure under slight internal pressure. In
other applications, the Panel Guard may cycle on and off to maintain enclosure temperatures.
NOTICE: The thermostat’s reaction to temperature change depends on several factors: the internal and external
heat loads, enclosure size and proximity to the heat source. When the internal heat load is zero (or very low) and
when external temperatures are below 50°F (10°C), the thermostat will take longer to react to air temperature
increases. There will be a lag between the rising air temperature and when the thermostat reacts, which can result
in temperatures inside the enclosure exceeding 125°F (52°C). When air and thermostat temperatures equalize, the
reaction to temperature change is improved and the lag is minimized.
Maintenance
Panel Guards can be disassembled for cleaning. Do not remove or adjust the brass thermostat.
Unscrew the cold cap and remove the generator for cleaning.
Temperature ranges are calibrated at the factory and are non- adjustable.
Troubleshooting
Insucient airow or cooling may be caused by the following:
1. Undersized compressed air line size.
2. Compressed air pressure too low.
3. Partial or complete blockage of internal compressed air path, due to dirt.
Insucient cold air temperature may be caused by:
1. Compressed air line temperature too high.
2. Water vapor in the compressed air supply.
3. Loose cold cap. This may occur if not tightened properly after disassembled for cleaning.
If trouble persists, please contact Vortec at 1-800-441-7475.

Table 2: Determining Compressed Air Line Size
1. Calculate total product compressed air consumption (SCFM, SLPM).
2. Determine length of compressed air line required for connection to main supply.
3. Locate pipe length in left column and read to the right to nd the compressed air requirements.
4. Locate pipe size at top of column.
