Model that is permanently wired:
This product must be connected to a grounded,
metallic, permanent wiring system, or an equipment
grounding terminal or lead on the product.
Power supply wiring must conform to all required safety
codes and be installed by a qualified person. Check
that supply voltage agrees with that listed on product
nameplate.
Extension cords:
Use only a 3-wire extension cord that has a 3-blade
grounding plug. Connect extension cord plug to a
matching 3-slot receptacle. Do not use an adapter. Make
sure your extension cord is in good condition. Check that
the wire gage of the extension cord is the correct size wire
to carry the current this product will draw. An undersized
cord is a potential fire hazard, and will cause a drop in line
voltage resulting in loss of power causing the product to
overheat. DIAGRAM B indicates the correct gage cord for
length required and the ampere rating listed on the product
nameplate.
If in doubt, use the next heavier gage cord. The smaller
the gage number, the heavier the wire gage.
Model with a power supply cord:
This product must be grounded. For either 120-volt or
220/240-volt circuits connect power supply cord
grounding plug to a matching grounded outlet. Do not
use an adapter. (See DIAGRAM A)

OPERATION
Injury Hazard
Use only recommended air handling parts
acceptable for pressure not less than 10 psi.
When provided, motor terminal covers must be in
place for safe operation.
Product surfaces may become hot during operation,
allow product surfaces to cool before handling.
Do Not direct air stream at body. Air stream from
product may contain solid or liquid material that can
result in eye or skin damage, wear proper eye
protection.
Do Not spray flammable or combustible liquid.
Failure to follow these instructions can result in
burns, eye injury or other serious injury.
WARNING
DIAGRAM C
Start Up
If pump fails to start or slows down significantly under load,
shut off and disconnect from power supply. Check that the
voltage is correct for the pump.
Safety switch system(only in DBMX and DBMS series)
When diaphragm is broken, the protrusion on top of the
magnet frame will activate microswitch and shut down the
power to prevent further damage.
Alarm control system( optional )
The control is equipped with a three position toggle switch
(DIAGRAM C). Operation in each switch position is as follows.
RUN:
During normal operation the switch is in the RUN or
center position. The unit will function fully automated in
the RUN mode. In the event of two pressure situation
( low or high pressure) the controller will sound an alarm
and light a visual indicator light to attract the operator of
those conditions (lower & higher pressure).
MUTE:
The MUTE position will allow the unit to continue to run
but will silence the audible alarm while leaving the visual
alarm active.
TEST:
The TEST position will activate both the
audible and visual alarms to check to
see if they are functioning properly.
