Congratulations on the purchase of your new MOJAVE Monitor Dry Vacuum System that provides
state of the art regenerative side channel vacuum technology. This vacuum system is designed
for reliable operation in the modern dental facility. The system uses a 100% oil-less Vacuum Pump
to produce the high-volume air flow required for multiple simultaneous users, while the Separator
Tank ensures that no liquids enter the pump.
In addition, the system incorporates an efficient energy management system. This is accomplished
using a Variable Frequency Drive (VFD) for each Vacuum Pump, which is controlled by a Master
Controller. This controller automatically adjusts the frequency of the pumps to maintain the required
vacuum level depending on the needs of your dental facility. With this balanced system, each user
always has the flow rate necessary to do the job while conserving electricity and prolonging the life
of your pumps. The MOJAVE Monitor Dry Vacuum System is hereafter referred to as MOJAVE in
this manual.
CONGRATULATIONS

As shown by Figure 1, MOJAVE consists of the major components listed below.
Vacuum Pump Assemblies V3M, V5M or V7M.
A single-stage pump, where all of the wetted metal parts are nickel plated or stainless steel.
A metal electrical enclosure that houses a VFD, circuit breaker, Cooling Fan and an
interface PCB.
An aluminum heat exchanger to cool the exhaust air from the pump before it travels through
the exhaust vent. (Heat exchanger not included with -NHE models).
A metal chassis for mounting components.
10 Gallon Separation Tank Assembly MT10-M.
A molded plastic tank that is capable of holding 10 gallons of liquid.
An internal float switch that signals the Master Controller to turn the vacuum pump OFF if
the liquid level exceeds the preset level.
A washout port with internal nozzle that is used to rinse the interior of the tank during the
automatic Washout Cycle.
A metal chassis for mounting components.
Continuum Separation Tank Assembly CT20-M.
The continuum tank combines two molded plastic tanks connected via a check valve and
two solenoid valves. This tank is capable of handling an infinite volume of liquid because
one tank section drains as the other tank section fills, while maintaining a preset vacuum
level.
Each tank has an internal float switch that signals the Master Controller to toggle the state
of the tank and air solenoid.
Solenoids keep the liquid moving through the tanks by controlling the venting and pressurization
of each tank.
Each tank has a washout port with internal nozzle that is used to rinse the interior of the tank
during the automatic Washout Cycle.
A metal chassis for mounting components.
Master Controller. This self-contained metal enclosure is mounted on the front of the MT10-M or
CT20-M tank chassis. The unit includes a Main PCB, a LCD Display and Touchscreen that provides
the following system functions:
Provides the operational user interface for the MOJAVE system.
Monitors and displays the frequency, vacuum level and temperature.
Records the run time, in hours, of up to 4 connected pumps.
Balances the vacuum load equally across all running pumps.
Displays any error/fault codes.
Controls the Washout function.

Figure 2. Typical MOJAVE Functional Flow Diagram
Vacuum System Operation.
Air, water, and solids from the operatory are pulled into the separator tank. Air is expelled out through
the pump exhaust while liquids and solids fall to the bottom of the tank. The vacuum in the tank keeps
the check valve to the drain closed and the tank gradually fills.
In single tank (MT10-M) configurations, if the rising fluid level actuates the float switch, the Master
Controller stops the operation of all connected pumps and an optional drain pump (sold separately) is
turned on for one minute. With pump operation idle, the vacuum is no longer being maintained and
the check valve of the tank drain opens allowing liquids and solids to drain from the separator tank.
Once the tank drains, the Master Controller automatically restarts the primary pump.
Systems using the continuum tank (CT20-M), which is capable of handling infinite liquid volume
capacities, operate differently. Each tank has an internal float switch. The tanks also use two
2-way solenoids. The float switches control the state of the two solenoids to allow the filling and
draining of each tank, keeping the liquid moving through the tanks. When the top tank is filling,
the bottom tank is draining and when a bottom tank is filling, the top tank is draining. The preset
vacuum level is maintained in either state. If the top float switch is active, the Master Controller stops
the operation of all connected pumps. Once the tank drains, the Master Controller automatically restarts
the primary pump.
When an instrument (suction tip) has been opened, the Master Controller senses an increase in vacuum
demand and will instruct the VFD to speed up the motor.
Conversely, when an instrument (suction tip) has been closed, the Master Controller will instruct the VFD
to slow motor operation down due to decreased vacuum demand. The Master Controller can also turn
on and off up to 4 connected pumps to regulate the vacuum level.
Additionally, the Master Controller initiates a 2-minute tank washout cycle when the system has been in
Standby for 5 minutes.

INSTALLATION INFORMATION
General. For new installations it is recommended to follow the following guidelines:
Make sure to install the system in accordance with all local electrical and plumbing codes.
Sizes of each suction line from the operatories differ between MOJAVE systems. See Site Requirements
provided on page 12.
The suction line should not have any sharp right angle bends and must be sloped a minimum of ¼
inch for every 10 feet toward the separation tank.
The drain on the base of the separation tank must be connected to a vented or an open floor drain
capable of handling 10 gallons in 30 seconds. Drain pipe size 1½inch schedule 40.
The drain line should be a short run with a minimum slope of ¼ inch for every 10 feet toward the
drain (avoid any sharp right angle bends).
Vent line requirements differ among MOJAVE systems. See Site Requirements.
Make sure to install the supplied exhaust vent assembly to the bottom end of the facility vent line.
The vent should be sloped ¼ inch per 10 feet towards the pump. Vent lines must be capable of
handling vapors and liquids.
The outside vent must be protected from rain and animals.
A flexible air exhaust hose is provided to connect to the 2 inch diameter vent pipe and heat exchang-
er. Hose clamps are provided to secure hose to heat exchanger and pipe.
Wash-out water supplied via ½inch copper tubing terminated with a ½inch FNPT shut-off valve
providing water pressure between 20 and 100 psi.
Wash-out port on the tank top is a 3∕8inch push to connect elbow that connects to the water supply
via supplied 10 foot 3∕8inch Poly tubing and ½MNPT x 3∕8inch push to connect adapter.
As shown by Figure 1, the Master Controller is delivered mounted on the front chassis of the fully
assembled MT10-M or CT20-M tank associated with the system. In addition to the water connection
at the washout solenoid, electrical and vacuum connections must also be made.
Accessory packs and system installation kits shipped with associated MOJAVE systems are listed
below. Refer to the Installation Section for a listing of components supplied with each kit and the
instructions necessary to install specific MOJAVE systems.
Run a network cable into the room where you will set up your Mojave to allow connection to the
Vision Monitor.
Constant power MUST be supplied to the system at all times. Applications where power cannot be
constantly provided, such as in many mobile dentistry environments, are not recommended for use
with this system and will void the warranty.
Grounding reliability can only be achieved when the Master
Controller is connected to a HOSPITAL GRADE receptacle.
