INSTALLATION/OPERATION INSTRUCTIONS

CONCEALED DAMAGE OR MISSING PARTS:

IMPORTANT: FOR YOUR PROTECTION, PLEASE READ AND OBSERVE THE FOLLOWING:

This steam booster has been thoroughly inspected and carefully packed before leaving our warehouse.
Concealed loss or damage means loss or damage which does not become apparent until the booster has been unpacked. The

contents may be damaged in transit due to rough handling even though the carton may not show external damage.
If it is found that the shipment has concealed damage, PLEASE DO NOT RETURN IT TO JACKSON, but notify the carrier

(within 48 hours) asking them to send their agent to fill out an inspection report. Save the cartons so he may inspect them and
be sure to note in the report any black marks, creases, tears, crushed corners or any other marks indicating rough handling.
Also, notify your JACKSON representative immediately.

If it is discovered that there are missing parts, please notify your JACKSON representative immediately.

EQUIPMENT MOUNTING:

Your booster should come pre-assembled and will require that it be permanently mounted in place. The platform has pre­punched holes in the legs to allow for mounting to the installation floor. NOTE: The J120 must be properly mounted and level
before being used. Once the platform is secure to the floor, attach the water and steam lines in accordance with local and
national codes.

PLUMBING:

NOTE: ALL CONNECTIONS MUST COMPLY WITH ALL APPLICABLE LOCAL, STATE AND NATIONAL PLUMBING
CODES.

The plumber is responsible that the water line is THOROUGHLY FLUSHED BEFORE connecting it to any manual or solenoid
valve. It is necessary to remove all foreign matter such as chips (resulting from cutting or threading pipes), pipe joint compound
or, if soldered fittings are used, bits of solder or cuttings from the lines. This debris, if not removed, may lodge in the valves
and render them inoperative.

The J120 is designed to take incoming water from a minimum temperature of 110 BF to approximately 180BF for use in the final
rinse of your dishmachine. In order to do this, water is supplied to the booster and is heated by tubes carrying 15-25 PSIG flow
steam. Heat is transferred from the steam into the water, raising the temperature.

Install condensate drains in accordance with applicable codes.
The J120 is designed to operate at a water flow rate of 20 A5 PSI. The assembly comes with a water pressure regulator, which

is preset at the factory. However, adjustment may be required so ensure that you verify the the flow pressure before beginning
operations. See the instructions regarding adjustment and maintenance of the water pressure regulator for more information.

WARNING: The J120 Booster is designed to heat water to a minimum of 180BF and is extremely hot during operations.
Advise personnel of the dangers associated with touching booster components as burns or severe injury can occur.
