DAMAGE TO THE EQUIPMENT.
When unit is received, immediately inspect for external or internal damage. Report any damage
to the carrier. Following inspection, keep the packaging material with the unit.
Minimum door or hallway opening to move the unit is 1.45 meters (57 inches). The unit length
of 2.62 meters (103 inches) should also be considered for negotiating any corners.
When choosing a location for the unit be sure that the floor will support the unit’s operational
weight of 1633 kg (3600 lbs). Minimum clearances required are 1067 mm (42 inches) right and
left, and 762 mm (30 inches) at the rear.
Once the unit is in position for installation, level it front to rear and right to left by adjusting all
five feet.
Secure unit to the floor through the holes provided on flanges of the feet. Use at least two bolts
for each foot.
Before connecting utilities, remove the rear covers of the unit. Each utility connection is labeled.
1. The WaterJet must be supplied with power as follows:
Supply Voltage
Amperes (MFS)
Herz
Phase
Amp Draw
2. Follow local codes or the National Electrical Code (NEC) to select the proper size wire to the
unit.
3. Make watertight conduit connections for the electrical supply through the control panels in
the rear of the unit. Be sure to maintain the watertight seal in the box.
4. Attach each phase leg as shown marked inside the control panels.
5. Make a watertight conduit connection at the marked opening inside the main Control Box
for the temperature chart recorder through the control panel in the rear of the unit. Be sure
to maintain the watertight seal in the box.
6. An electrical schematic of the WaterJet Control Panel and chart recorder connections is
provided at the rear of this manual, and on the inside of the main Control Box. The refrigeration unit electrical schematic can be found on the inside panel of the control box.
7. Double-check the wiring phase legs to ensure that they are attached to the correct terminal
on the terminal block.

WATER CONNECTIONS
CAUTION
PIPING CONNECTIONS AND
INSTALLATION MUST BE MADE BY
A QUALIFIED INSTALLER. IMPROPER
INSTALLATION CAN CAUSE DAMAGE
TO THE EQUIPMENT.
LOCAL CODES AND/OR NATIONAL
PLUMBING CODES MUST BE
OBSERVED WHEN MAKING
CONNECTIONS TO THE WATERJET.
HOT WATER SUPPLY MUST NOT
EXCEED 49º C (120º F). EXCESSIVE
HEAT CAN DAMAGE VALVE SOLENOIDS.
DRAIN CONNECTION
WARNING
BACTERIAL HAZARD! IMPROPER
INSTALLATION COULD RESULT IN
IMPROPER DRAINAGE, AND ALLOW
DRAIN MATERIAL INTO THE UNIT.
1. The WaterJet has a maximum water capacity of 1325 liters (350 gallons). Water pressure
from the supply needs to be between 2.07 bar (30 PSI) and 4.14 bar (60 PSI).
2. There are two 3/4 inch NPT water solenoid connections at the rear of the WaterJet. These
connections are for hot and cold water as labeled.
3. If hot water is not to be used, also supply the hot water solenoid inlet with cold water. Both
solenoids should be connected to cold water under such circumstances, or the unit will not
work.
1. Connect the drain at the rear of the unit using a 1-1/2 inch NPT pipe. Do not use plastic or
PVC-type pipe.
2. Install the drain line with a constant downward pitch. Ensure that there is a vertical air gap
of at least two inches from the top of the drain unless otherwise specified by codes.
3. The WaterJet has a maximum drain rate of 284 liters (75 gallons) per minute. If the building
drain is slower than the WaterJet drain, the two inch drain line may need to be restricted to
a smaller diameter compatible with the building drain and the drain time will be lengthened.
CAUTION
PIPING CONNECTIONS MUST BE MADE
BY A QUALIFIED INSTALLER. IMPROPER
INSTALLATION CAN CAUSE EQUIPMENT
DAMAGE. LOCAL CODES AND/OR
NATIONAL PLUMBING CODES MUST BE
OBSERVED WHEN MAKING PLUMBING
CONNECTIONS TO THE UNIT.

MAKE NECESSARY REFRIGERATION
ADJUSTMENTS. (INSTALLER MUST BE
R.S.E.S. CERTIFIED).
1. The steam system is ASME shop inspected, stamped (PP) and registered with the National
Board for operation up to a maximum working pressure of 90 PSIG.
2. Connect the steam supply to the labeled 3/4” NPT connection at the safety relief valve
located on the rear of the WaterJet.
3. Recommended boiler capacity should be nine (± two) BHP.
4. Connect the condensate return line to the labeled 3/4” NPT pipe connection which is found
directly under the steam input line.
5. Globe valves (shut-off valves) are not provided with the unit, but should be installed as
required.
1. Connect refrigeration lines (Suction, Liquid and Hot Gas) as labeled at the rear of the unit.
2. Refrigeration unit must be no more than 100 feet of piping.
3. The 1-5/8” suction line, 7/8” liquid line and the 7/8” hot gas line should be welded with
nitrogen-purging during all brazing connections.
4. The suction line must have traps for every rise of 10 feet. In addition, all horizontal runs
must have a slope of not less than one inch for every 10 feet in the direction of the condensing unit.
5. Mineral oil must be added to the unit.
6. A 39 pound pre-charge of R22 is required for the condensing unit. An additional charge
must be added dependent on the line length from the condensor to the WaterJet.
Before Replacing Rear Covers on the Unit:
1. Run the WaterJet through a few cycles before replacing covers. This can be done without
food being prepared or placed in the unit. These “practice runs” will help identify any latent
installation problems such as:
a. Improper motor rotation due to improper phase wiring.
b. Loose solder connections which cause solenoid valves to stay open.
c. Leaks in any of the connections.
Initial Start-Up
1. Do not attempt to operate the unit until a qualified R.S.E.S. Certified Groen installer has
completed the necessary refrigeration adjustments.
2. The Groen installer will instruct the facility supervisor on the proper start-up procedure and
provide additional instructions as needed.

WARNING
DOORS WILL BE HOT WHEN UNIT IS
COOKING OR RETHERMING. CONTACT
CAN CAUSE SEVERE BURNS.
IMPROPER INSTALLATION OR
TIGHTENING OF FITTINGS CAN RESULT
IN HOT WATER LEAKS.
WARNING
STEAM ESCAPES WHEN THE DOORS
ARE OPENED. CONTACT CAN
CAUSE SEVERE BURNS.
Operation
Intended Use
Hot water supply is used to accelerate cooking or retherming times. Steam supply of nine Bhp
(± two) is required to obtain and maintain temperatures for proper and safe cooking. Retherming cycles may require some preheat time, depending on the type of food being warmed and
the steam supply.
The WaterJet is intended to chill 100 gallons of casing product. It is intended to cook up to 500
lbs of meat per cycle. Individual meat size can be up to 10 lbs.
Casings should be filled and sized so that the bags may be folded around a temperature probe,
to measure internal product temperatures.
PROGRAMMING & CHILL TEMPERATURE SET (Graphic Representation)
Once turned on, the WaterJet 100 is programmed and run from the Operator’s Console:
WARNING
DISCONNECT POWER BEFORE
SERVICING THE WATERJET.
ONLY REPLACE COMPONENTS WITH
GROEN PARTS NON-GROEN PARTS
COULD RESULT IN ELECTRICAL SHOCK.
CAUTION
DO NOT CLOSE SUCTION LINE VALVE.
FAILURE TO KEEP VALVE OPEN DURING
OPERATION WILL CAUSE THE
EVAPORATION TO LEAK.
The unit is programmed using the upper row of controls:
