Note: Always follow local health and safety protocols for worker safety and
personal protection.

Note: Drive-Points are designed for single use installations (temporary or
permanent). They are not meant for reuse.

Installation with a Manual Slide Hammer

1. Ensure that all components are clean prior to use.
2. Thread the Multilevel Drive-Point Tip into the bottom of the Multilevel Drive-
Point Port that will be the lowest in the assembly, or use a coupling to connect
an extension to the tip, then thread the port onto the extension. Tighten
components with pipe wrenches.
3. Cut a piece of tubing for each port to the depth of the proposed port installation
plus an additional 1.5 m (5 ft). Identify the top of tubing. Consider cutting
the tubing tops to different lengths (e.g. longest tubing length is deepest port;
shortest denotes shallowest port).
4. Connect the 3/8" OD or 1/4" OD sample tubing to the barbed port stem by
pushing firmly until the tubing reaches the base of the barb – 1/4" OD tubing
will reach the base of the first barb and 3/8" OD tubing will reach the base of the
second barb.
5. Slide a length of extension pipe over the tubing, and thread it firmly into the port.
Allow the free end of the sample tubing to turn freely to avoid twisting within
the extensions. Longer tubing lengths may require rotating the excess tubing by
hand.
6. Continue adding extensions and couplings to the depth required, or suitable
'working height' to use the Slide Hammer assembly (3 ft. long). Use pipe
wrenches on all joints.
Important: There needs to be at least a 6" extension between ports. The
Tubing Bypass can not be threaded directly to a port.
7. Slide the Tubing Bypass over the tubing and tighten it firmly onto the extension
pipe, with the tubing extending through the side hole.
WARNING: When connecting or removing the Tubing Bypass, allow the sample
tubes to turn freely to avoid twisting. Longer tubing lengths may
require rotating the excess tubing by hand.
8. Slide the hammer over the Drive Head and operate the hammer to drive the
device until only about 15 cm (6") of the extension pipe below the Tubing Bypass
remains above the ground.
