nent is missing, do not substitute parts. Call the Edelbrock Customer Service line at 800-416-8628.
Proper Assembly of the Pump Station
1. Select mounting location for transfer pump. Lowest point of transfer pump should be located above
highest point of tallest bottle you intend to fill. Bolt pump securely in place.
2. Install bottle stand on your nitrous oxide source bottle (if it is non-siphoned).
Note: The bottle stand supplied with this kit is designed
to work with non-siphoned 65-lb. source bottles using a
CGA 660 exit style of valve produced by Purittan-Bennet,
which are the most common used for the Edelbrock refill
station. It is possible to use smaller nitrous oxide source
bottles. To do so, you must first determine if your source
bottle has a siphon tube. If so, the bottle must remain up-
right to transfer properly. If it does not have a siphon tube,
it must be inverted for proper transfer operation. The
point of identifying which source bottle you have is to en-
sure that the liquid nitrous oxide and not the gaseous ni-
trous oxide is drawn out of the source bottle to the bottle
being filled.
3. Install Teflon washer and 6 AN bottle nut on the nitrous oxide source bottle.
4. Invert the nitrous oxide source bottle and place near the transfer pump.
Note: Bottle should be chained to a structural support
and must be near enough to the where transfer
pump will be mounted for the 6 AN 6 ft. hose to
reach from the source bottle valve to the transfer
pump.
Note: Always use Teflon pipe sealant on all pipe
(NPT) fittings.
5. Install the blue 3/8 NPT x 6 AN fitting in the transfer pump
N
2
O outlet port (arrow on bottom of pump indicates flow
direction).
6. Install the blue ½ NPT x 6 AN fitting in the transfer pump
N
2
O inlet port.
7. Install the blue 3/8 NPT x ¼ NPT female reducer in the
compressed air inlet port. This port can be found in the front center of the pump.
8. Install ¼ NPT male union in the 3/8 NPT x ¼ NPT fitting at the compressed air inlet port.
9. Install compressed air on/off valve on the ¼ NPT x ¼ NPT fitting at the compressed air inlet
port.
10. Ensure valve is in its closed position. Connect your air supply to the ¼ NPT inlet of the on/off
valve using a air supply fitting that correctly mates with your air supply hose. Due to vast styles
of air connections, this fitting is not included in the Nitrous Refill Station. Inspect lines and fit-
tings for leaks. Find and repair leaks, if any.
Note: If you desire to mount the compressed air on/off valve assembly remotely, or in a differ-
ent orientation, ¼ NPT adaptors can be purchased at most local hardware stores.
11. Connect the N
2
O filter outlet port (marked by arrow on filter) to one end of the 1 ft. 6 AN hose.
Connect the opposite end of the 1 ft. 6 AN hose to the blue ½ NPT x 6 AN fitting at the transfer
pump inlet port.
12. Connect inlet port of the N
2
O filter to the nitrous oxide source bottle by using the 6 ft.
6 AN hose. The other end will attach to the 6 AN bottle nut on the source bottle.
