pump’s inlet filters MUST be located in a clean breath-
able air location at all times. Breathable air drawn into the inlet filters
MUST meet at least the requirements for Type 1 Gaseous Air de-
scribed in the Compressed Gas Association Commodity Specification
G-7.1 (Grade D or higher), as specified by Federal Law 30 CFR, Part
11, Subpart J, 11.12(b).
The requirements of Grade D breathable air include:
* Oxygen ................................19.5 - 23.5%
* Hydrocarbons (condensed)
in mg/m
3
of gas ....... 5 mg/m
3
maximum
* Carbon Monoxide ....... 10 ppm maximum
* Carbon Dioxide...... 1,000 ppm maximum
* No toxic contaminants at levels which would make the air unsafe to
breath.
Refer to the C.G.A. Commodity Specification G-7.1 for complete details.

Assembling the Free-Air Pump
The only assembly required on an EDP30 or EDP50 Pump is to attach
the air supply hose quick-disconnect pod(s) to the pump’s manifold.
1. Remove the pump from its shipping pallet and the air supply hose
quick-disconnect pod(s) from their shipping carton.
2. The air supply hose quick-disconnect pods can be located in the
work area, up to 300 feet from the pump. Use Bullard’s Cat. No.
V60, 100 foot extension hose to extend the pod(s): (If V60 extension
hose IS NOT required, go to instruction 3).
a) Attach the V60 extension
hose to the pump’s manifold.
If extending only one pod,
connect the V60 hose to the
manifold Kamlok coupler
that is not plugged. Lock the
Kamlok male fitting on the
hose to the Kamlok female
coupler on the manifold
(Figure 1).
If you are not using the other manifold coupler, leave the Kamlok
plug installed to prevent air from freely flowing.
NOTE
Due to the relatively high volume of air pumped through the V60
hose, the first 100 feet of hose may tend to vibrate. The vibration
dissipates as additional lengths of hose are added.
b) If additional lengths of V60
extension hose are required, connect
them together using the Kamlok
couplers (Figure 2).
DO NOT EXTEND THE POD(S) MORE
THAN 300 FEET (3 LENGTHS OF
V60 HOSE) FROM THE PUMP’S
MANIFOLD.
c) Attach the pod(s) to the end of the
V60 hose. They should be connected
so that the handle and pressure
relief valve are on top of the pod
(See Figure 3).
Lock the Kamlok Male Fitting on the
Pod to the Female Coupling on the
Hose.
3. If the V60 extension hose is not
required, assemble the pod(s) directly to
the pump’s manifold. The pods should
be connected so that the handle and
pressure relief valve are on top of the
pod (See Figure 4).
If using only one pod, connect it to the
manifold Kamlok coupler that is not
plugged. Lock the Kamlok male fitting
on the pod to the female coupler on the pump’s manifold.
Leave the plug in the other coupler to prevent air from freely flowing.
