DC50 Series Dual-Cool Climate Control
Tube and DC70 Vest Instruction Sheet
Operating the Dual-Cool Tube
1. To obtain cooler air, turn the air temperature control knobs counterclockwise
(Figure 3)
. Maximum cooling is obtained when knobs are open completely
and when there is maximum airflow out of the Dual-Cool tube’s exhaust ports.
To obtain air that is closer to ambient temperature, turn air temperature
control knobs clockwise. If knobs are closed completely, your respirator will
receive air that is essentially at ambient temperature.
nOTe
There are separate controls to adjust the temperature of the air that
is distributed to the vest and the breathing zone. The right-hand knob
controls the air temperature to the respirator; the left-hand knob
controls the air temperature to the cooling vest
(Figure 3)
.
2. When finished working, leave the work area wearing the respirator. With the
air still flowing, remove the hood, and then disconnect the air supply hose
using the quick-disconnect coupler attached to the Dual-Cool.
Cleaning
Machine wash the vest in warm water using a gentle cycle. Use a mild laundry
detergent. Air-dry only. After cleaning, carefully inspect the vest for any signs
of damage. If any damage is detected, remove the vest from service.
