qUse only 45° elbows to make turns in main line.
qMake sure to use the proper pipe type for associated system.
qIf piping is diverted to clear an obstruction, DO NOT MAKE A TRAP.
See detail A, Main Line Turn Connections.
qDO NOT use standard 90° elbows.
SUB FLOOR INSTALLATION -
Recommended system installation layout should be used
whenever possible.
Notes:
1. 10-foot Maximum Height from Main
Line to Tank.
2. Consult Dental Unit Manufacturer's
Guidelines for correct reduced size
and height of termination of vacuum
line inside junction box.
3. Limit branches. Orient main line
under junction box or cabinet.
4. When piping line is above 3/4" I.D.
or larger, use 45° Y's & elbows only.
5. Recommend installing separate line
connection for scavenger when using
Nitrous scavengers in overhead
piping installations.

INSTALLATION NOTES:

A. PUMP INSTALLATION SPACE - Area for stacked or side by side pump installation. Keep 4 inch space from walls. Only stack up to 2 pumps in one area.
B. TANK INSTALLATION SPACE - Area for typical side by side tank installation. Keep 4 inch space from walls. Never install the CT20 / CT22 tank on top of a pump.
C. SEWER DRAIN - Provide a drain for the removal of waste liquids from the MOJAVE tank. Use an open drain pipe (1½”inch P-Trap with 1 inch air gap or
oor sink) or a closed vented drain. See detail 1.
D. TANK WASHOUT - Provide a water source terminated with a ½” inch FNPT shut-off valve providing water pressure between 20 and 100 psi for daily tank
washout. Valve location must be no more than 10 feet from the tank installation to allow connection of supplied 10-foot 3/8-inch Poly tubing to the tank
washout port. Provisions for backflow prevention may be required. Check local code requirements.
E. MASTER CONTROLLER ELECTRIC OUTLET - Master Controller requires a dedicated standalone 120V, 5 AMP or 220V, 5 AMP grounded receptacle.
F. PUMP ELECTRIC SERVICE - Each Mojave pump is wired directly with a dedicated 220V, 20 AMP, single phase 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 each other and 3 feet of installation center line.
G. SUB FLOOR INSTALLATION VACUUM LINE - See Plumbing Requirements for connection to tank input via supplied hose.
H. OVERHEAD INSTALLATION VACUUM LINE - See Plumbing Requirements for connection to tank input via supplied hose.
J. HEAT EXHAUST - See Plumbing Requirements for the exhaust vent line required for specific Mojave configurations. Use metal pipe on systems whenever the
Heat Exchanger is removed. Schedule 40 pipe can normally be used on typical Mojave configuration installations with a Heat Exchanger. When installing two
pumps, a reducing Y adapter (shown by detail 2 above) is needed to connect both vent tubes to a common 3-inch exhaust vent line.
K. PUMP/TANK MANIFOLD - User fabricated to connect 3 or 4 pumps to a tank. Used with 3V5 and 4V5 systems. See Pump/Tank Connection Manifold.

HEAT EXHAUST CONNECTION NOTES
1. VENT LINE - The exhaust vent line required for MOJAVE systems using
the Heat Exchanger and systems with the Heat Exchanger removed
have different requirements.
Use metal pipe on systems without a Heat Exchanger while PVC
Schedule 40 pipe can be used on systems with a Heat Exchanger.
Do not make a trap in the exhaust vent piping. Do not use 90 οfittings.
Also see Exhaust Vent Protection and Ventilation Requirements below.
2. V3, V5 & V7 PUMP EXHAUST VENT CONNECTION - Connection between
the pump and exhaust vent piping is typically made via the supplied 2-inch
Black Flex tubing.
3. EXHAUST VENT ASSEMBLY - The supplied assembly must be
installed at the lower end of the vent pipe to collect condensation
produced during pump operation. The bottom of the Y connector
should be located 18 inches from oor. Attach the drain tube to the drip
leg quick-connect tting to allow drainage into oor drain/sink.

Exhaust Vent Protection.
If the exhaust piping is venting to the outside of the building, precautions must be taken to protect
the equipment room from weather elements and animal intrusion. This can be accomplished by
using one of the three methods shown on the right. Wall-Mounted Outside

Exhaust Vent Requirements.
The MOJAVE equipment must be used in a controlled-temperature environment. Maintain
equipment room temperature between 40 and 105 degrees Fahrenheit. An exhaust fan is
necessary if room temperature is not maintained by other methods.
Adequate forced ventilation must be provided across the unit by placing an appropriate
exhaust fan opposite an equivalent air intake vent . The fan should be placed higher than the
associated intake vent. Recommended minimum exhaust fan requirements for each MOJAVE
unit are listed to the right.
Note: Only 1 pump is running when operating in idle mode.
