CONGRATULATIONS
PURPOSE OF THIS MANUAL
This manual provides installation, operation and maintenance instructions for the support of the
MOJAVE LT3 Dry Vacuum System,consisting of one LT3 Dry Vacuum Pump and Air/Water Separator
assembly housed on a chassis. Review and follow the guidelines included in this manual to ensure
that the system provides the highest level of service.
Congratulations on the purchase of your new MOJAVE LT3 Dry Vacuum System that provides
state of the art vacuum technology. This vacuum system is designed for reliable operation in the
modern dental facility. The system uses a 100% water-less Vacuum Pump to produce the high-
volume air flow required for multiple simultaneous users while the Air/Water Separator ensures
that no liquids enter the pump.
The MOJAVE LT3 incorporates an efficient energy management system. This is accomplished by
adding a Variable Frequency Drive (VFD) to the Vacuum Pump. This system automatically adjusts
the frequency of the pump 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 pump.
SAFETY SUMMARY
Use of the MOJAVE LT3 not in conformance with the instructions specified in this manual
may result in permanent failure of the unit.
WARNING: To prevent fire or electrical shock, do not expose this equipment
to rain in or moisture.
All user serviceable items are described in the maintenance section.
Manufacturing date code on serial number label is in the format Month YYYY.

MOJAVE LT3 Dry Vacuum System Operation.
1. Air, water, and solids from the treatment room enter the system via the Inlet Port and are pulled
into the mechanical air/water separator assembly.
2. Air is then expelled to the outside vent through the pump heat exhaust
3. Liquids and solids exit through the drain line of the separator.
4. The LCD touch screen provides the operational user interface for the MOJAVE LT3 system. It
monitors and displays the frequency, vacuum level, RPM reading and temperature as well as
recording the run time in hours.
Automatic Vacuum Adjustment.
When an instrument (suction tip) has been opened, the system senses an increase in vacuum demand
and responds by increasing the speed of the motor.
Conversely, when an instrument (suction tip) has been closed, the system reads the elevated vacuum level
and responds by slowing motor operation down due to decreased vacuum demand.

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.
The suction line should not have any sharp right angle bends and must be sloped a minimum
of ¼inch for every 10 feet toward the MOJAVE LT3.
The drain on the base of the air/water separator must be connected to a vented or an open
floor drain capable of handling 5 gallons in 1 minute. Drain tube size 1 inch.
The drain line should be a short run with a maximum rise of 3 feet. Avoid any sharp right
angle bends.
Make sure to install the supplied exhaust vent assembly to the bottom end of the facility vent line.
The vent should be sloped ¼inch 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.

Installation Notes.
Installation Layout Space. Figure 4 shows the requirements for the installation of MOJAVE
LT3. Please note that all units are shipped with leveling feet set to lowest position. Heights can be
increased by 1 inch by adjusting the leveling feet. Refer to Figures 5 and 6 for connection details.
A. PUMP INSTALLATION SPACE - Area for MOJAVE LT3 pump in typical installation.
B. SEWER DRAIN - Provide a drain for the removal of waste liquids from the Air/Water Separator assembly.
Use an open drain pipe (1 ½inch P-Trap with 1 inch air gap or floor sink) or a closed vented drain.
See Figure 6.
C. HEAT EXHAUST - Refer to Figure above and see Plumbing Requirements for the exhaust vent line required
for MOJAVE LT3. Schedule 40 pipe can be used on MOJAVE LT3.
D. PUMP ELECTRIC SERVICE - The MOJAVE LT3 pump is wired directly with a dedicated 220V, 20 AMP, single
phase 50/60 Hz circuit. If Main Circuit panel is not located in equipment room, a disconnect box with approved
ground is needed for each pump. Disconnect boxes should be mounted no more than 3 feet of the installation

MOJAVE LT3 Connection Procedure. Using industry standard techniques, make the three
connections between the LT3 with supplied components from accessory kits Refer to Figure 5
for the connection diagram and perform the following procedure.
1. Treatment Room Suction Line to Pump Inlet Connection. Refer to Figure 5, item (1) .
a. Install one connector adapter to the pipe (either overhead or sub floor) from the operatory.
b. Install the connector adapter into the flexible coupling connector on the LT3.
c. Install the 1½" ID, clear hose cut for installation between the operatory suction line and
pump inlet and secure with two no-hub adapters.
2. Heat Exhaust Connection. Refer to Figure 5, item (2) for the location of the vent hose connection
at the pump heat exchanger output and the facility vent line. Make the heat exhaust connection by
performing the following procedure.
a. Exhaust Vent Assembly Installation. Refer to Figure 6 and install the Drip Leg and Exhaust
Vent Assembly to the bottom end of the facility vent line. Install a length of 1/4 inch OD
Urethane Tubing (P/N 51453) between the vent condensation drain port and facility sewer
drain.
b. Heat Exhaust Vent Connection. As shown by Figure 6, connect the vent hose
between the pump heat exchanger output and the facility vent line. Secure with no hub
adapters provided by the accessory kit.
Important: Make sure to efficiently use space by making connections as short and direct as possible
to meet your particular site requirements.
Make sure that all hose connections are straight and secure without any sharp bends or kinks.
Since the vacuum hose is rigid, make sure not to stress connections especially at the pump inlet.
