Should the air pressure require adjustment, loosen the locknut on the pressure relief
valve and adjust the top sleeve to achieve the proper pressure (see Figure 4).
Clockwise will increase the pressure, counter-clockwise will decrease the pressure.
Re-tighten the locking nut when adjustment is complete to prevent inadvertent changes
to the adjustment. The pressure relief valve may vent in order to prevent the pump
from exceeding the recommended pressure. This is normal as long as the pressure on
the gauge is correct for the respirator used.
FIGURE 4
DO NOT ADJUST THE PRESSURE RELIEF VALVE TO ALLOW THE PRESSURE TO EXCEED 15 PSIG MAXIMUM.
PUMP DAMAGE WILL OCCUR AND THE WARRANTY ON THE PUMP WILL BE VOIDED IF THE PUMP IS
ALLOWED TO OPERATE ABOVE 15 PSIG PRESSURE.
Allow the air to purge through the respirator and hose assembly for a few minutes to eliminate any odors or tastes in the respirator
assembly. Don the respirator and re-check the outlet pressure gauge prior to entering the contaminated work area.
When finished working, exit the work area wearing the respirator with the air still flowing. Once outside the contaminated area,
remove the respirator, turn the pump off, then disconnect the air supply hose using the quick-disconnect couplers.
Refer to the respirator’s instruction manual for proper inspection, maintenance and storage procedures for the respirator.
Warning: Do not use extension cords longer than 30 metres (100 feet) or rated
less than fifteen (15) amperes when operating this device. We recommend using
a minimum 12-gauge grounded extension cord with a length not exceeding 30
metres (100 feet). Pump damage will occur and the pump's warra nty will be
voided if this practice is not followed.
