MPI-300 Installation & Operations Manual
IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS.
Read this manual completely before operation of AGW–0500 Ozone Generator Equipment. The High Voltage
Transformers in this unit create 7,000 volts, with the outer jacket of the High Voltage lead reaching 3,000 volts.
- USE EXTREME CAUTION -
Operate the AGW–0500 on a near level surface with safe access to electrical power.
Connect to a G.F.C.I. type receptacle.
Follow all applicable electrical codes.
Do not bury cord.
WARNING: To reduce the risk of electrical shock, replace damaged cord immediately.
ELECTRICAL SHOCK HAZARD: Turn OFF all power switches and disconnect power cord from power source receptacle
before performing any service work. Failure to do so could result in serious injury or death.
SAFETY CLAIMS
Performance safety testing was based on the Hazard Communication Standard as promulgated through the Occupational Safety
and Health Act of 1970 and documented in the Code of Federal Regulations, Title 29, Chapter XVII, Part 1910, Section 1910.1200.
The inherent low hazard due to the AGW-0500’s design and construction, coupled with the safety features, monitoring data, and the
precautionary directions provided in the owner’s manual are sufficient for The Toxicology Group, LLC, a division of NSF International
(Ann Arbor, MI), to provide a professional opinion that the AGW-0500 Mobile Ozone Surface Sanitation System poses no safety
concerns when operated under the prescribed conditions as set forth in the owner’s manual.
ANTIMICROBIAL CLAIMS
This device has been determined acceptable for use as an ozone generating device providing sanitization and disinfection of hard,
inanimate, pre-cleaned surfaces, in and around food processing areas (P1). A potable water rinse is not required following the use of
this device on previously cleaned hard surfaces.
NSF International Registration for this device is based, partially, upon documentation indicating that it meets all necessary requirements
including labeling, EPA Establishment Registration, and safety requirements set forth under Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA) of June 5, 1947, Section 2(q)(1) and Section 7.

MPI-300 Installation & Operations Manual
SECTION 1 GENERAL
INFORMATION
1A. Description
The MPI-300 is available in three different
configurations, MPI-300, MPI-300WM, and MPI-
300M. The MPI-300 is the base model system
designed for general, in place surface sanitation
applications including equipment sanitation of
conveyors, slicers, saws, etc. as well as direct
contact on food. The MPI-300WM (wall-mounted)
and MPI-300M (mobile) are designed as manually-
operated surface sanitation systems utilizing the
included ozone delivery hose and spray wand.
The systems flow ozonated water at approximately
3.3 GPM with an applied ozone dose of 3-3.5 PPM.
Average dissolved ozone concentration at the
spray nozzle is 2.0 PPM with clean, potable source
water free of chemicals and minerals. The MPI-
300 provides a final sanitizing rinse, leaving no
residual.
The MPI-300 is designed to sanitize wettable
surfaces and equipment including converyors,
containers, saws, slicers, walls and floors, in
addition to certain foods. Compatible materials
include stainless steel, plastics, wood, concrete,
cement, cement block, painted and unpainted. The
MPI-300 uses interchangeable attachments for
spray applications.

1C. Layout & Accessories
The MPI-300 is a low pressure, ozone enriched
cold water surface sanitizer. Internally it is
separated into two basic sections – dry and wet –
as discussed below and shown in Figure 1, page 2.
1C1. Dry Section - Ozone Generation:
• Air Compressor: oilless, piston air compressor
pumps ambient air at 2.5 CFM into the oxygen
concentrator
• Oxygen Concentrator: the oxygen concentrator
uses a PSA (pressure swing absorption) molec-
ular sieve to remove dirt, moisture, nitrogen and
other trace gases, producing oxygen at greater
than 85% purity and less than -60° C dewpoint.
Concentrated oxygen feed-gas enables ozone
generation at 2-6% (by weight) concentration.
• Ozone Generation Cell: the corona discharge
ozone generation cell consists of an aluminum
housing (ground, two end housings, and fasten-
ers), gaskets, high voltage stainless steel elec-
trode, ceramic dielectric, oxygen inlet fitting, and
ozone outlet fitting. Concentrated oxygen gas is
pulled into the ozone generation cell under vac-
uum. The oxygen molecules are split into atomic
oxygen which then recombine to form ozone gas.
1C2. Wet Section - Ozone Dissolution in Water:
• Ozone Injector: Inlet water flows through
the ozone injector, creating vacuum that pulls
ozone gas from the ozone generation module
and injects the ozone into the water flow. The
injector is sized and factory preset to dissolve a
minimum of 90% of the ozone gas into the water
flow continuously.
• Ozone Degas Chamber: ozone-enriched water
from the ozone injector flows into the degas
chamber where the counter-current design forc-
es any undissolved ozone gas through the float
valve-protected top vent to the Ozone Destruct.
• Ozone Destruct: undissolved ozone gas pass-
es through the heated catalytic ozone destruct
which is made of non-consumable manganese
dioxide (heat protected from moisture fouling).

MPI-300 Installation & Operations Manual
The manganese dioxide and heat offer redun-
dant ozone destruct capabilities.
• Ozone-Enriched Water Out: ozone-enriched
water exits the unit through the water outlet
fitting. All available hose and hose attachments
are specifically sized to provide the exact pres-
sure and flow parameters necessary to allow the
system to function correctly. Use of any attach-
ments other than those approved by DEL will
result in non-optimum operating ameters

SECTION 2 INSTALLATION
2A. Location
MPI-300 & MPI-300WM
The MPI-300 and MPI-300WM are designed to
be permanently wall or frame-mounted using the
mounting tabs on the enclosure. See Figure 2 to
the right.
MPI-300M
The MPI-300M mobile cart-mounted system is
designed to be conveniently rolled to a location
close to your process. This can be a level location
either indoors or outdoors.
For all systems, allow for access to protected
electrical power and required water connections.
The point of ozonated water discharge from the
spray wand, spray gun, or customer-supplied
nozzles must NOT exceed 6 feet in height above
the water outlet on the MPI.
2B. Electrical
Main Power Supply Circuit: The MPI-300 is
supplied with a standard 1 foot power cord. Plug
cord into standard grounded 20 Amp GFCI type
receptacle only.
2C. Plumbing
MPI-300
The standard MPI-300 is supplied with 3/4” FPT
bulkhead fittings for water inlet and outlet. It is
designed to be plumbed on site per the user’s
requirements.
CAUTION: Back pressure on the system caused
from the outlet plumbing must not exceed
10 psi. Contact DEL Ozone or an authorized
distributor for assistance with your specific
installation.
MPI-300WM & MPI-300M
The MPI-300WM is supplied with a 3/4” FPT
bulkhead fitting for water inlet and is designed to be
plumbed on site per the user’s requirements. The
MPI-300M is supplied with a garden hose adapter
at the inlet. Both systems are supplied with a quick
connect fitting at the outlet for the ozone delivery
hose connection. A standard garden hose (1/2”
minimum) can be connected to the water inlet hose
adapter on the MPI-300M. For both systems, source
water must be a minimum of 4 GPM at 40 psi.
