INSTALLATION INSTRUCTIONS

VISUAL INSPECTION:

Before installing the unit, check the container and machine for damage. A damaged container is an indi-

cator that there may be some damage to the machine. If there is damage to both the container and machine, do not throw away
the container. The dishmachine has been inspected and packed at the factory and is expected to arrive to you in new, undam-
aged condition. However, rough handling by carriers or others may result in there being damage to the unit while in transit. If
such a situation occurs, do not return the unit to Jackson; instead, contact the carrier and ask them to send a representative to
the site to inspect the damage to the unit and to complete an inspection report. You must contact the carrier within 48 hours of
receiving the machine. Also, contact the dealer through which you purchased the unit.

UNPACKING THE DISHMACHINE:

Once the machine has been removed from the container, ensure that there are no miss-

ing parts from the machine. This may not be obvious at first. If it is discovered that an item is missing, contact Jackson imme-
diately to have the missing item shipped to you. 

LEVEL THE DISHMACHINE:

The dishmachine is designed to operate while being level.

This is important to prevent any damage to the machine during operation and to ensure the
best results when washing ware. The unit comes with adjustable bullet feet, which can be
turned using a pair of channel locks or by hand if the unit can be raised safely. Ensure that
the unit is level from side to side and from front to back before making any connections.

PLUMBING THE DISHMACHINE:

All plumbing connections must comply with all applica-

ble local, state, and national plumbing codes. The plumber is responsible for ensuring that
the incoming water line is thoroughly flushed prior to connecting it to any component of the
dishmachine. It is necessary to remove all foreign debris from the water line that may poten-
tially get trapped in the valves or cause an obstruction. Any valves that are fouled as a result
of foreign matter left in the water line, and  any expenses resulting from this fouling, are not
the responsibility of the manufacturer. A water hardness test must be performed to deter-
mine if the HTS-11 (scale prevention and corrosion control) need to be installed. A hardness
test kit is attached to the warning tag that is attached to the y-strainer toward the front of the
machine. If the hardness is higher than 5 GPG the HTS-11 will need to be installed, please
contact Jackson immediately to have this item shipped to you.

WATER SUPPLY CONNECTION FOR MACHINES WITH A WATER HARDNESS
GREATER THAN 5 GPG: 

Ensure that you have read the section entitled “PLUMBING THE

DISHMACHINE” above before proceeding. Install the HTS-11 into the water line (1/2” ID
pipe size minimum) before the dishmachine line y-strainer using copper pipe. The HTS-11
must be installed vertically. A mounting bracket is provided to facilitate the venture metering
head to the wall. Observe proper inlet/outlet water directions. Flow directions are molded
into the top of the head. It is recommended that a water shut-off valve be installed before
the HTS-1 to allow access for servicing. Plumb from the HTS-11 outlet to the y-strainer using
copper pipe (or order the 1/2” ID flexible hose kit offered by Jackson). The water supply line
is to be capable of 20

±

5 PSI “flow” pressure at the recommended temperature indicated on

the data plate. See “Pressure Regulator” and “Shock Absorber” sections.

WATER SUPPLY CONNECTION FOR MACHINES WITH A WATER HARDNESS OF 5
GPG OR LESS:

Ensure that you have read the section entitled “PLUMBING THE DISHMA-

CHINE” above before proceeding. Install the water supply line (1/2” ID pipe size minimum)
to the dishmachine line y-strainer using copper pipe (or order the 1/2” ID flexible hose kit
offered by Jackson). It is recommended that a water shut-off valve be installed in the water
line between the main supply and the machine to allow access for service. The water sup-
ply line is to be capable of 20

±

5 PSI “flow” pressure at the recommended temperature indi-

cated on the data plate. 

PRESSURE REGULATOR: 

Do to areas where the water pressure fluctuates or is greater

than the recommended pressure, it is recommended installing a water pressure regulator. Do not confuse static pressure with
flow pressure. Static pressure is the line pressure in a “no flow” condition (all valves and services are closed). Flow pressure
is the pressure in the fill line when the fill valve is opened during the cycle.
