Features/Benefits
Spread Voltage The Dual Wet Vacuum
system can be wired directly to 208 and 230
VAC electrical circuits, eliminating the need for
buck and boost transformers.
Swing Check Valve Eliminates the need for
inconvenient manual shut-off valves and
provides a positive seal for one pump operation.
Secondary Filter Traps any materials too
large to pass through the pump and features
easy-to-clean convenience.
Pump Controls For convenience, all con-
trols are located on the outside front of the
unit. Dual-lighted switches allow for individual
activation of each pump. Vacuum adjustments
can be easily made and checked with the
adjustment control and gauge.
External Vacuum Adjustment For conve-
nient and accurate vacuum adjustment when
needed.
Rugged Frame and Enclosure Designed
for strength and easy access to all assemblies.
Instrumentation Vacuum level at a glance.
Two Quiet-Running Motor/Pump Assem-
blies For back-up protection. Motors are
designed for continuous operation and long life.
Pumps are solid brass castings, precision machined for long and trouble-free service not
affected by modern dentistry chemicals. 1 HP
and 2 HP motors are available. Both pumps can
be operated during peak work periods.
Pre-Wired for Remote Switch Allows
quick pick-up of third wire for a remote lighted
operatory switch.

Section II Pre-installation
The following Pre-installation information will assist
in making a quick, easy and quality installation. However, if there are any questions, contact a CustomAir
technical service representative at 1-866-DTE-INFO.
Site Requirements
Before the Dual Wet Vacuum System can be properly
installed, the following utilities must be supplied:
Electrical
All electrical supply lines and control wiring should
be supplied and installed by a licensed electrician
according to local building codes. The Dual Wet
Vacuum System requires two separate circuits
(one for each pump motor) of the correct voltage for
the system ordered. In addition to the thermal overload
protection built into the motors, each circuit must be
provided with a circuit breaker, time delay fuse or
standard fuse. See the Motor Protection Chart below
for recommended breaker or fuse amperage.

Water
Water line must be installed by a plumber according
to local building codes. Terminate water line in 1/2"
FIP gate valve.
Waste
— CAUTION —
A free-flowing discharge system is required for
proper operation of the vacuum system. Dual
pump systems may leak at the anti-siphon valve
if the discharge system is restricted. Ensure the
vacuum system is installed and cleaned in accor-
dance to the instructions in this manual.
Waste line must be installed by a plumber according
to local building codes. For requirements, see Typical
Installation Options, Page 4 and Waste Line, Page 6.
V acuum Lines
Vacuum lines be installed by a plumber according to
local building codes. Vacuum lines and risers to be
IPS, PVC, Schedule 40, unless local codes require
another material such as copper. Slope all vacuum
lines toward the vacuum producer 1 inch for every
20 foot run. Make all vacuum line connections using
long radius sweep fittings.

esuFdradn
Low Voltage Control Line (Optional)
If remote low voltage is desired, a licensed electrician
should install 18-3 thermostat wire for lighted switch or
18-2 thermostat wire for non-lighted switch from the pump
location to the operatory switch located up to 150 feet
away. If the operatory switch is over 150 feet away from
the pump location, use 16-3 thermostat wire for lighted
switch or 16-2 thermostat wire for non-lighted switch.
— IMPORTANT —
All vacuum systems must be installed according
to local building and electrical codes.

Section III Installation
Water Supply Line
The water going to the unit acts as a pump sealant
and cooling agent. When the Vacuum System is in
operation, the water supply must be on at all times.
The plumber supplies and installs a 1/2" gate valve
on the water supply line. Connect the 3/8" nylon
tubing and fittings, which are supplied with the unit,
as illustrated.

V acuum Line
Vacuum lines must be installed by a local plumber
according to local building codes. All vacuum lines
and risers are recommended to be IPS, PVC, SCH.
40. Type M copper should be used if local code
does not allow the use of PVC.
Care should be taken to slope the lines 1" for every
20' of run toward the vacuum pump(s). This allows
waste and liquids to flow with gravity, contributing
to the efficiency of the vacuum system.
Make all connections using long radius sweep fittings. To promote unrestricted flow of air and waste
liquids through the vacuum lines, directional flow
connections should be used.
Using 45º elbows for turns or avoiding obstructions
is best; however, do not make a trap in the line,
doing so will decrease the efficiency of the system.

All elbows and tees should be sized for the main line
and sized down with busing reducers to accommodate smaller lines.
Avoid sagging lines, which cause the formation of
traps in the system and prevent good air and waste
liquid flow.
Connect the evacuation system to the vacuum line
using the hose and fittings supplied in the installation
kit. The vacuum line can be installed from the right
or left side of the cabinet.

Section III Installation
Waste Line
The waste line carries water and liquid waste from
the operatory to the building's sewer system.
The waste line should follow the most direct path to
the sewer connection with a minimum of bends and
elevations, and must be installed according to local
building and plumbing codes.
The waste line can be installed from the right or left
side of the cabinet.
The exhaust connection should be made by either of
two methods, floor sink connection or direct connection to P trap, depending on local code and building facilities.
Dual Wet Vacuum System
— IMPORTANT NOTE —
No part of the waste line should be more than
three (3) feet above the level of the waste
connection on the vacuum pump.
DIRECT CONNECTION T O “P” TRAP
Use P trap-air gap, if required by local code. Install
as illustrated.

FLOOR SINK CONNECTION
Use floor sink adapter SA-200, Part No. 6-4504-013.
