1. Turn the compressor off after workers have left the hazardous work area.
2. Allow the pressure to bleed down before trying to disconnect the compressor hose to the filtration system.
3. Disconnect all hoses and install safety dust caps on couplings.
4. The system is now ready for storage.
Do not store or transport vertically.
5. Model TA-3EA: Close cylinder valve(s) and replace storage caps.
6. Refill air cylinders for next usage.
STEP 4)
Plug compressor into a 115 volt
receptacle with a dedicated 20
amp service.
Note: If an exten-
sion cord is going to be used,
the cord must be rated for a
minimum 20 amp service (12/3
gauge).
STEP 1)
Compressor must be attached to a Grade-
D filtration unit. A minimum of 1/2” I.D.
hose is to be used between the compressor
and the Grade-D filtration unit.
STEP 6)
Attach respirator supply hose to outlet fittings
on Grade-D filtration unit. Never leave an open
(unused) respirator attached to the system as
output pressure will not be maintained.
STEP 5)
Turn on the compressor and note the gauge
pressure reading on the compressor. Al-
low twin receiver tanks to fill to system
pressure 110psi (7.5 bar) output.
Note: Do not replace the coupling supplied on the compres-
sor tank outlet except with a checked style coupling of at least
1/2” I.D. Do not use a Chicago style coupling on this type of
compressor.

STEP 7)
Adjust the regulator on the Grade-D filtration unit to the required
output pressure (psi) of the pressure demand respirator. Review
manual on the Grade-D filtration unit and carbon monoxide monitor
for details on operation, service, and calibration before commencing
work. Attach and don respirator.
STEP 3)
Open cylinder valve and adjust the regu-
lator on the reserve air cylinder to the de-
sired output pressure of the respirator.
STEP 2)
Connect reserve air hose to the reserve
air regulator and the back-up air inlet
fitting on the Auto-Air Grade-D fil-
tration unit. A 1/4” industrial inter-
change fitting is supplied on the re-
serve air regulator and Auto-Air filter
unit.
Warning: Always locate compressor in a fresh air environment away from toxic dusts, vapors, and fumes.
