NOTICE
Any operation involving work on pipe containing liquids or gases
under pressure is potentially hazardous. To ensure a safe working
environment, always follow proper procedures including those
available from the equipment manufacturer and your company.
No person is authorized to make plastic pipe joints for natural gas service
unless that person has been qualied through training, assembling,
fusing and testing specimens in accordance with 49 CFR 192.285.
It is the responsibility of the operator to establish a method to
determine that each person making joints in pipelines in their system
is qualied to make those joints.
This manual does not serve to replace but should be used as a
supplement to hands-on training. This manual is not intended to be
used for system design purposes and does not take the place of the
advice of a professional engineer.
Should any issue or diculty arise while operating this equipment,

INTRODUCTION
Description
The MTD MultiClamp is a multi-functional clamping solution for
polyethylene electrofusion ttings. It is capable of securing 90° elbows, 45°
elbows, 22.5° elbows, 3-way tees, and couplings from 6”IPS through 16”IPS.
Safety
WARNING: Read this manual thoroughly before operating the MTD
MultiClamp system. Under no circumstances should the factory
recommended specications be exceeded.
If the operator or other personnel have questions regarding the
operation of this system, please contact ISCO. Always refer to and
follow your company’s safety procedures.
Protective Clothing
Gloves, ame retardant shirt, safety glasses, safety shoes, and hard hat
are recommended. Do not wear jewelry, loose clothing or other items
that could get caught in moving parts.
Warnings
WARNINGS in this manual indicate a potentially hazardous situation
which, if not avoided, could result in death or serious injury, as well as
damage to equipment. They may also be used to alert against unsafe
procedures.

PROCEDURES
Step 1: Conguring the MTD MultiClamp
Before setting up the MTD MultiClamp, determine what type of
tting you will be clamping, and congure the clamping assemblies
accordingly.
Note: Multi-Angle Connector is not required for some couplings. One
of the clamping assemblies may be used as a bar-style clamp with
two V-Clamps.
After determining the conguration, slide the clamping assemblies into
the Multi-Angle Connector, and tighten clamping assembly bolts against
the slots in the Multi-Angle Connector using the included hex tool.

Step 2: Installing Sliding V-Clamp Base
In order to install the V-Clamps on the MTD MultiClamp assembly, rst
install the sliding V-Clamp bases. There are four bases provided, one
for each V-Clamp.
To install a V-Clamp base, place the bottom half of the base beneath
the assembly and push up through the slot, as pictured below.
Next, place the top half of the base onto the assembly from above so
that it sits securely on the pegs of the bottom half. Supporting the base
from the bottom, insert one of the provided hex screws into the base’s
center slot from above and tighten until the base is securely fastened
to the assembly, as pictured below.
Repeat this process until you have installed enough bases for the
V-Clamps you plan to use.

Step 3: Installing and Adjusting V-Clamps
Before placing tting assembly into clamping assembly, determine the
distance you will require for the V-Clamps to sit under the pipe and
adjust the position of the bases accordingly.
Note: Some ttings will require removal of one of the two V-Clamps
from each sliding base.
Note: V-Clamps should be clamped to the pipe rather than the tting.
To install a V-Clamp, place it on the base installed in Step 2, and install
the bolts to fasten clamp to base.
Once the bolts have been threaded, use the provided hex tool to
tighten and fasten into place, as pictured below. If it is determined that
clamps need to be adjusted after installation, use hex tool to loosen
and adjust clamps as required.

8
Adjusting V-Clamps according to tting
After adjusting the V-Clamps to desired positions, securely tighten
them to the sliding V-Clamp base using the included hex tool so that
there is no movement of the V-Clamp on the sliding base.

Step 4: Place tting assembly in MTD Multi-Clamp
Place tting assembly to be fused in Multi-Clamp. Ensure that V-Clamps
are supporting pipe rather than ttings themselves.

Note: Some ttings may require support blocks. If this is necessary,
wooden blocks may be used as support blocks.
Step 5: Secure tting assembly to MTD MultiClamp
After tting assembly is properly situated in Multi-Clamp, install nylon
straps on V-Clamps by passing one end of strap through ratchet
mechanism slot and hooking the other end around the desired rung on
the opposite side of the V-Clamp.
Note: Nylon strap must be passed through the ratchet mechanism from
the underside rather than the top side.

Placing hook end around rung on V-Brace
After installing straps, tighten ratchet mechanisms on each V-Clamp to
secure pipe and tting to the clamp.
Step 6: Fuse tting assembly
After tightening all straps, ensure that the tting assembly cannot move
in the clamp. If all pipe and ttings are secured, you can now fuse the
assembly.
