MANUFACTURERS LIMITED WARRANTY

MVP GROUP CORPORATION (Jet-Tech Systems) hereby warrants all new warewashers bearing
the name “JET-TECH” and installed within the continental United States of America or Canada to be
free from defects in material and workmanship, under normal and regular usage and operation, for a
period of one (1) year following the date of original installation (unless specified otherwise) but in
no event can exceed eighteen (18) months from the date of shipment from the factory.

This warranty is valid ONLY for the original owner of the “Jet-Tech” unit and is not transferrable.

If a defect in material(s) or workmanship is detected or found to exist within the above stated
period, MVP Group Corp., at its sole discretion, shall either repair or replace any original
equipment manufacturers part which has proven to fail within the machine, providing that the
equipment has not been altered or tampered with in any manner, has been installed correctly as
per the owner’s manual and maintained and operated in complete accordance with this manual.

The labor cost to repair or replace any part proven to be defective, as per above clause(s), shall be
covered by MVP Group Corp., within the continental United States of America or Canada provided
that prior authorization for this labor was approved by MVP Group Corp., the service work was
performed by an authorized MVP Group Corp., service agency and that this agency installed an
original and genuine Jet-Tech part in the machine. Any repair work performed by a non-authorized
service depot remains the sole responsibility of the user and MVP Group Corp., will not be held
responsible. The installation of any generic part will not be valid and therefore voids this
warranty. All authorized labor coverage shall be limited to regular hourly rates only. Any
supplemental hourly rates or charges, such as weekends, holidays or emergency premiums remain
the responsibility of the user.

MVP Group Corp., (Jet-Tech) hereby states that warranty travel time shall be limited to and
without exception, a round-trip total of two (2) hours OR mileage up to a maximum of one hundred
(100) miles (160 KM) round-trip. Any charges exceeding those stated herein must have prior
authorization by the factory or will be at the customer’s expense.

Exceptions to above warranty are: (A) Damages resulting from shipping, handling or abuse. (B)
Incorrect installation and/or connections. (C) Adjustments or calibration of any parts. (D) Faults due
to lack of regular maintenance or cleaning of any internal part(s). (E) Replacement of any wearable
items such as peristaltic squeeze tubing or gaskets. (F) Excessive lime, mineral, alkali or hard
water conditions (In excess of 6 grain) and (G) Poor results due to use of an incorrect type of
detergent or rinse additive (for non-commercial type applications or products containing chlorine)
and excessive or inadequate water temperature(s) or pressure conditions or incorrect use.

MVP GROUP CORPORATION STATES THAT THERE ARE NO OTHER WARRANTIES,
EXPRESSED OR IMPLIED, THAT ARE NOT SET FORTH HEREIN, MVP GROUP
CORPORATION SHALL ASSUME NO OTHER RESPONSIBILITY, EITHER DIRECT OR NON -
DIRECT OR BE LIABLE FOR ANY OTHER OR ADDITIONAL LOSS OR DAMAGE WHETHER
BEING DIRECT OR CONSEQUENTIAL, AS A RESULT OF ITS EQUIPMENT.

This dishwasher must be installed on a level, rigid, nonflammable surface. Ensure
that the machine is level by installing the feet (shipped in the wash tank of the
machine) and adjusting the leveling. Be sure to provide adequate space for
water, drain and electrical connections. The rear panel must be removed for the
hook ups and must be replaced after the connections are made.

ELECTRICAL SUPPLY

A 115 Volt - 20 Amp circuit breaker is required for this washer. A power-

cord with NEMA 5-20 plug is provided for your convenience.

**WATER SUPPLY**

A 3/4” NPT coupling is required with 30 psi. dynamic pressure. A water

pressure regulator* may be required. The water pressure cannot be less

than 30 psi or exceed 30 psi. If the water pressure exceeds the prescribed
amount, you will get inconsistent washing temperature, premature failure and
thus may void the warranty.

Incoming water temperature must be 140º F (60º C). An easily accessible shut-
off valve is recommended, making installation, service and maintenance easier.

A flexible fill hose is provided to make installation, servicing and
maintenance easier.

Make sure that the water is free from calcium and hard water
deposits. For these situations, an inline water cartridge system is
highly recommended. Build-up of calcium and lime deposits in the
washer may occur and servicing will be required on a more
frequent basis which will not be covered by the warranty.

**DRAIN CONNECTION**

This washer has a gravity type drain. Since this unit is a “Counter-
Type” installation, the flexible drain hose provided should be

connected to the drain outlet elbow at the rear of the unit behind the
rear access panel; and extended through the side opening directly
into a floor drain or
sink (see Figure )

All panels must be replaced on the unit when the
installation is completed.

DO NOT manually fill wash tank with water. The dishwasher will fill

automatically when the power is turned ON.

pull the bottom away from the machine and lift the

panel.

The terminal block is located inside the back cover. Pass the cable through the cable strain relief and

connect the wires to the terminals L1 (brown wire), L2 (blue wire) & Ground (yellow & green wire). Replace

the top & back panels being careful not to pinch or kink any

wires or hoses. There should be sufficient cable length to

permit the machine to be pulled out for service.
