Operating the Free-Air Pump
WARNING
THE RESPIRATOR USER MUST NOT ENTER THE CONTAMINATED WORK
AREA UNTIL ALL OF THE FOLLOWING STEPS HAVE BEEN COMPLETED
1. Analyze the atmosphere at the location of the air inlet and the pump itself
to be sure the pump will not be operating in a contaminated or an explosive
atmosphere.
2. If Using an EDP10 Pump:
Plug the pump into a 115 volt electrical outlet. The pump’s motor is equipped
with a toggle switch and a 7 foot (2 m) grounded cord with a standard three-
prong plug.
If using the EDP10HM, no additional set up is required for the run hour meter
to operate.
For extension cords, 12 AWG (15 amps) or heavier duty gauge is recommend-
ed. Bullard also recommends that the distance be limited to 100 feet, the plug
be three-prong grounded, and that only one extension cord be used.
Plug the pump into a 220 volt electrical outlet.
If Using an EDP16TE Pump:
Plug the pump into a 115 volt electrical outlet. The pump’s motor is equipped
with a toggle switch and a 7 (2 m) foot ground-ed cord with a standard three-
prong plug.
You may use up to 100 (30.5 m) feet of 50 amp, 3-wire grounded extension
cord to reach your electrical outlet. We recommend using 12 gauge wire.
Avoid excessive lengths of extension cord, especially if running the pump
continuously.
The pump’s motor is equipped with manual reset thermal overload protection
for 115 volt operation. The reset button is located on the side opposite the
toggle switch.
The EDP16TE may be rewired for 208/230 volt, 60 Hz operation. If rewired to
208/230 a suitable starter/contactor and thermal overload protector must be
provided by the user. The conversion work should be performed by a qualified
electrician.
If Using an EDP16HAZ Pump:
The EDP16HAZ must be wired for either 230 or 460 volt, 3-phase, 60 Hz
operation.
THE USER MUST SUPPLY AN ExPLOSION-PROOF THERMAL OVERLOAD
PROTECTOR AND A STARTER/CONTACTOR SWITCH.
Proper wiring should be performed by a qualified electrician.
REFER TO THE MOTOR NAME PLATE OR JUNCTION BOx COVER FOR PROPER
WIRING DIAGRAM.
WARNING
PROPER MOTOR SELECTION AND WIRING (IN ACCORDANCE WITH LOCAL
AND NATIONAL ELECTRIC CODES) IS THE RESPONSIBILITY OF THE USER.
3. Each pump will operate sitting on its four rubber mounts. It does not need
to be bolted down. If desired, the pump may be mounted on a wall or ceil-
ing as long as the shaft center line is horizontal.
4. Make sure the pump’s inlet
filter is located in a clean,
uncontaminated location
where breathable air is
assured at all times (see
Figure 3).
If the inlet filter can-
not be placed in a clean
breathable location, install
Bullard’s 50 foot (15 m)
Inlet Extension Hose Kit
(Cat. No. V50IN) to the
pump’s inlet port. See the
directions shipped with
the Extension Hose Kit for
assembly instructions.
If clean breathable air cannot be guaranteed at all times within this 50 foot
(15 m) reach, you may add up to five (5) additional lengths of 50 foot (15 m)
Extension Hose (Cat. V50Ex).
Therefore, you may place your inlet filter up to 300 feet (91.4 m) (6 x 50)
away from the pump. Do not add more than 300
(91.4 m) feet of inlet extension hose to
the pump.
5. Assemble your respirator by following the manufacturer’s directions as
described in the respirator’s instruction manual. Be sure the pump’s outlet
pressure, measured by the pressure gauge on the pump, is greater than
the minimum MSHA/NIOSH approved pressure required to operate the
respirator.
The respirator’s minimum approved pressure will be found in the respira-
tor’s instruction manual and/or on labels attached to the respirator.
If you have any questions as to whether or not your respirator is compat-
ible with this pump, call Bullard’s Customer Service Department at 1-800-
827-0423 or 1-859- 234-6616.
6. Connect the respirator’s NIOSH approved air supply hose(s) to the quick-
disconnect outlet coupler(s) on the pump (see Figure 4).
