General Before operating the unit, read these
operating instructions carefully in order
to understand the correct operation and
maintenance of the Mobile Ventilation
Unit (MVU) and to avoid injury or
damage to the MVU.
The Mobile Ventilation Unit is
constructed with the latest state-of-the-
art technology and safety features.
Nevertheless, it can be dangerous for
the user if not operated properly.
The MVU may only be serviced by
personnel who have been properly
trained in the hydraulic and operating
systems maintenance.
Ongoing training with the MVU as well
as education through specialty training
will guarantee proper performance and
reliability.

Protective
Clothing
Ventilator
Operation
Maintenance
To protect from the dangers of fire
fighting operations, wear appropriate
protective clothing and safety
equipment. For hazardous materials or
decontamination incidents, wear
appropriate safety clothing.
Never operate the MVU when on a
slope of more than +/- 5 degrees
longitudinal slope or +/- 2 degrees
lateral slope. Never move the MVU or
vehicle when fully elevated or during
fan operation.
Observe the gauges for the hydraulic
oil pressure while operating the MVU.
Maintenance and service should only
be conducted by persons who are
properly trained and know the safety
precautions and accident-prevention
procedures.
Disengage the battery cable prior to
performing any service or maintenance.

Protective
Devices
Electrical
System
The dismantling of protection-devices
and security arrangements may be
required during maintenance and
service. Directly after completion of
the work, all protective devices must be
reinstalled and security arrangements
again tested.
The MVU may not be operated in an
explosive environment!
Work on the electrical system may only
be performed by an electrician or by
trained personnel under the direction
and supervision of an electrician in
accordance with proper guidelines and
procedures.
When working on the electrical system,
disconnect the cable of the negative
terminal of the battery.
When connecting of the battery, – first
install the cable to the positive terminal,
and then the cable to the negative
terminal.
No metal objects should be placed on
the battery – this creates the danger of
a short circuit.

Battery
Disposal
Problems, like a loose connection
and/or frayed cable must be repaired
immediately.
Follow the safety warnings on the
vehicle battery!
Explosion Danger!
Fire, spark, open flame and smoking
are forbidden!
Avoid any spark sources when working
with the cable and electric devices!
Avoid short circuits!
Personnel Warning!
Battery acid is extremely corrosive,
therefore:
Wear hand protection.
Wear eye protection.
An unloaded battery can freeze,
therefore store it where it will not
freeze!
Properly recycle old batteries in an
authorized recycling facility.

Environment
Protection
Measures
During maintenance and replacement
of parts, only original parts from
Tempest Technology Corporation may
be used.
The use of spare parts and accessories
that do not come from Tempest
Technology Corporation or are not
tested and approved by Tempest, can
adversely affect the durability and
performance characteristics of the MVU
and affect operator safety!
Recycle oils, fuel, battery, and filters in
accordance with the legal and
environmental rules!
Never dispose of in water or rivers!
Store used fluids only in approved
containers!
Before throwing away a part or fluid,

Water Mist System
The MVU misting system is used for knocking down suspended gases, providing
additional cooling during ventilation operations and protection of exposures. It can also
be used for decontamination purposes.
Misting Ring: 1.5” diameter stainless steel, 12 nozzles
Flow Rate: 450 lpm @ 7 bar (130 GPM @ 100 psi)
Reach: 40 meters (130 feet)
Droplet Size: 200 microns
Supply: Central duct system
Misting Ring
A misting ring made from 1 1/2“ diameter stainless steel tubing is mounted forward of
the propeller inside the ventilator-shroud. A total of twelve evenly spaced, 65 degree
spray pattern nozzles on the ring provide a homogenous water fog.
The air stream generated by the ventilator is utilized to transport the water vapor. At a
flow rate of 3490 liters/minute and a delivery pressure of 7 bar the reach of the stream is
over 40 meters.
The finely dispersed droplets of the water vapor absorbe heat, inert fumes, and wash-
down hazardous vapors. Flow rates may be decreased or increased if so desired.
The heat absorption capacity amounts to 23,500 BTU/sec.
Water line connection, 1¼” FPT ball valve.

Clinometer
Indicates the degree of slope of the surface that the MVU is sitting on. Reads both
lateral and longitudinal slope. MVU scissors lift must not be elevated when the
clinometer exceeds either of the slope parameters listed below:
IMPORTANT:
Maximum lateral slope is two degrees (2O) in either direction.
Maximum longitudinal slope is five degrees (5O) in either direction.
Master Disconnect
The Master Disconnect turns off all power to the control panel. It is located on the right
hand side of the MVU control panel. The Master Disconnect Switch should be OFF
during storage of MVU.

18
Rotation Locking Pin
The MVU features a rotation locking pin to prevent wear and tear on the rotation system
during transport. The locking pin must be released prior to operating the MVU. The
locking pin is located on the operator side of the MVU at the top of the scissors lift
platform.
