muffler clockwise will increase the temperature and flow of the cold air. The black muffler may become
warm. An optional heat shield is available to protect the user’s body from the hot exhaust air, if desired.
(See Table 1).
The Cooling Tube can supply chilled air to the Vortec Cooling Vest or to a hood or helmet. When purchased
with the vest, the cooling tube is inserted into a sleeve on the vest; when purchased separately, the Cooling
Tube is supplied with a belt, with the Cooling Tube in a horizontal orientation on the user’s waist. If it
is desired to reposition the Cooling Tube so that it is vertical on the waist (for connection to a hood or
helmet), first remove the white plastic button at the end of the belt by pulling the two halves apart. Remove
the belt assembly from the metal belt bracket and then reattach it to the bracket through the alternate
slots. Loop the end of the belt through the male side of the buckle and reattach the white button in the belt
hole by pushing the two halves together. See Figures 1 and 2.
Cooling Vests
Upon receipt, inspect the vest and contact your Vortec representative immediately if you suspect
damage of any kind to the vest. Once the vest is placed into service, it may not be returned under any
circumstances. The Cooling Vest comes with the Cooling Tube already inserted into the sleeve on the vest.
Put the Vest on, and secure the front of the vest with the four Velcro fasteners. Be sure to leave enough
room to comfortably move in the vest. Connect the Cooling Tube to the air supply for cooling to begin.
The Cooling Vest may be used under welding leathers, coveralls or other protective garments, but the warm
exhaust air from the Cooling Tube must be vented outside of the garment.
Maintenance
The Cooling Tube may be disassembled for cleaning by removing the cold outlet fitting. Remove the O-ring
and the red, blue or brown nylon generator. Inspect the parts and clean or replace as needed (see Table 1
for replacement items). When reinstalling the components, it is important to torque the cold outlet fitting to
100 inch-pounds (11 newton meters) to ensure proper sealing. Check the filter elements in the compressed
air filter(s) and change if necessary.
Troubleshooting
Insufficient airflow may be caused by the following:
1. Undersized compressed air line size (See Table 2).
2. Compressed air hose too long (excessive pressure drop through hose).
3. Compressed air pressure too low.
4. Insufficient compressed air volume.
5. Partial or complete blockage of internal compressed air path, due to dirt or moisture freezing in the cold
air stream.
6. Loose cold outlet fitting (if disassembled for cleaning).
