1. General information
The MJet V3 is a unique device for installing fiber optic cable directly into pipe. The MJet V3 is comprised
of an air block and a belt drive that, when combined installs a cable into an airtight pipe, run at speeds
of 0 to 0-120m/min.
The MJet V3 greatly reduces pulling stress on the cable. The adjustable push force of the belt drive will
stall the motor or slip in the belt drive if the cable hits an obstruction.
The MJet V3 comes standard with a Digital LCD meter display, pipe packs and a service kit in aluminium
case.
These operating instructions contain a full description of the MJet V3, which have been designed for
the purpose of feeding fiber cable through pipes of uniform cross section. The pipe must have previo-
usly been installed underground or overhead to receive the fiber optic cable and must be of sucient
length on exit to be received by the machine. The pipe must be of material with sucient compression
strength for it to be adequately sealed in the pipe clamps of the machine. The pipe must be airtight up
to a pressure of 16bar. Pipe(s) sizes range from 10 mm-63 mm, while fiber optic cable(s) range from
4 mm-40 mm.
The MJet V3consists of an air block that is made in two halves that clamp together around the pipe.
The pipe clamps hold a seal that the fiber optic cable is fed through before entering the pipe. The pipe
clamps and cable seals can be interchanged to accommodate dierent pipe and cable sizes. The pipe
is mechanically clamped between the pipe clamps at the exit of the air block, preventing movement in
any direction. Seals conform around the pipe when clamped.
The fiber optic cable is fed through the pipe by a combined pulling/pushing force. The pulling force is
achieved when pressurized air is fed into the air block and forced into the pipe, generating drag on the
fiber cable from airflow passing over it. The pushing force is created by engaging the belt drive system.
As the belt drive feeds fiber cable into the pipe, drag force is created by the airflow. The fiber optic cable
floats in the pipe, minimizing any resistance to being pushed in by the belt drive.
The use of the MJet V3for operations other than those described in this manual are considered dang-
erous and are discouraged. Use of this machine for work other then what is intended, relieves the manu-
facturer from any responsibility, civil or penal. The manufacturer's responsibility ceases and the warranty
is voided when one of the following occurs:
A. When MJet V3 is used for purposes other than what is detailed in this manual.
B. Tampering and/or modifications carried out without written approval of the manufacturer.
C. Not using original manufactured replacement parts.
D. Poor maintenance.
E. Not using supplied safety devices or equipment.
F. Connection of this unit to machines and/or parts not produced or authorized in writing by the
manufacturer.
G. The MJet V3 should not be used to install any cable other than fiber optic cable specified within
the range outlined in this instruction manual.
H. The MJet V3 should not be run without oil in the oil mist canister, this will immediately void the
warranty.
Jetting is not responsible for injuries incurred as a result of improper use of the MJet V3.
