SECTION 3: Installation

After unpacking and before running, it is important to check that fasteners did

not become loose during shipping. Check all nuts, bolts and screws to make

sure everything is tight.

Check for proper voltage before connecting any power to the machine.

The voltage and amperage of the power supply depends on the specifications

provided by the customer. Information can be found on page 2 of this manual.

If you choose not to use the plug supplied with machine, run appropriate supply

voltage through a strain relief in the control box to the terminals labeled L1, L2

and L3, if three phase. Please refer to the electrical diagram in this manual for

the specific location.

3-1. Installation

IMPORTANT WARNING: All electrical connections

should be made by a licensed professional in accordance

with state and local codes.

6

Each set of bags consists of 6 individual units containing 2 layers each. The units

are secured to each other using hook and loop Velcro. Each bag has grommets on

the bottom corners and the end bags have grommets on the top in place of the

Velcro. The grommets on the end bags are spaced to easily slip over the bag pins

on the press area. The grommets on the bottom of the bags are used to secure the

bottom of the bags during the dumping process.

Knot the bag loops through the bottom grommets. We recommend having the bag

sets preassembled and bag loops attached, before inserting them into the press.

Place one layer only, into each section of the scissor assembly (you may find it

easier to begin at one end and work your way to the other end).

After all the layers are properly placed, grasp the bag loops and pull them over the

bag tab. Each bag corner is attached with one bag loop which gets attached to two

bag tabs as shown below.

SECTION 4: Operation

SAFETY GLASSES must be worn at all times during operation.

Beware of all pinch-points and moving parts.

Pressure factory set at 1800psi for extend and 2200 psi for retract (do not adjust)

1. Check to make sure all components are in place as described in the installation section.

2. Turn the disconnect switch to the “ON” position and pull the “E-Stop” button out to start the motor and pump.

3. Turn directional switch to the forward or reverse position until it stops (the motor and pump will continue to run).

The press does not need to be turned off when it is at full press stage, as there is a built-in override system which

is designed to maintain constant pressure without damaging the press.

4. Fill the open side of the press with slurry using a suitable pump. Do not fill one bag at a time, fill them uniformly.

5. Fill the bags 2’’ to 3” from the top.

6. Turn the switch to the forward or reverse position to press slurry. After pressing is complete allow the press to hold

for about 2 minutes longer to ensure full extraction.

4-1. Press Operation

7. The open side of the press is now ready to be filled. Repeat steps 3,4, and 5.

8. Turn the switch in the appropriate direction to begin squeezing the side just filled.

9. As the side previously pressed opens, gently work the cake separator between the bag and dry cake on

both sides of the cake on all layers.

** Be careful not to wear bottoms and sides of the bags by jamming the cake separator into the layers. Re-

member to always use your cake separator to loosen the cakes in the bags before dumping! Caution

should be used in order not to cut the seam on the sides of the bags. Always be sure all edges of the cake

separator are smooth, without nicks or sharp edges. Never force the cake separator. Gently cutting the

cakes in half will allow for an easier dump and increase the life of the bags.

10. When all cakes have been separated from the bag, press the “lift” button to raise and dump the dry cake

from the bags. When the bags are empty, flip the press area back over and repeat. The “lift” button must

be released when the press area reaches its pivot point in order to fall over.

SECTION 4: Operation



Factory preset is set to full speed. You may find it necessary to adjust the speed to get maximum yield. Soft pomace

needs to be pressed at slower speeds. This allows the juice to be extracted without the pomace overflowing the top of

the bag. The speed is adjusted by using the two vernier speed control knobs. To slow down the pressing cycle, simply

turn the appropriate knob clockwise.

If press is too slow: This will not have a negative effect on the juice or the

machine but will decrease the amount of produce per hour the machine can

handle.

If Press is too Fast: This generally causes undesired outcomes. 1.) The produce

can slide up and out of the press bag. 2.) The pressure inside the bag can climb

too fast, possibly causing the bag to rupture or forcing produce to extrude through

the bag. 3.) Juice will squirt up and out of the press. 4.) Produce will have lower

yields because there was not a slow gradual increase in pressure.

If press speed is just right: The press should be set to a speed such that the platen slowly

moves in and squeezes the produce while increasing pressure slowly. Due to the diversity of

produce, this machine is capable of processing the variety of characteristics contained in

various fruits and vegetables. Therefore, press speed should be adjusted to the customer’s

specific needs.

SECTION 5: Cleaning

Bags must be cleaned daily. If this cleaning procedure is neglected bags may become

clogged resulting in lower yields and/or damage to the bags.

1. Turn bag inside out.

2. Rinse bag thoroughly in sink, or hose down. All loose particles should be rinsed out.

3. Soak bags in a tub filled with a caustic solution (a lightly chlorinated solution). Goodnature can

supply cleanser if desired, please contact customer service at 716-855-3325. Bags should be

soaked for a minimum of 30 minutes up to 2 hours.

4. Place bags in a standard washing machine and add in a chlorine cleanser.

5. Run the machine with a cold wash, and a hot rinse (Ideally above 100F but below 140F). The

temperature of the rinse is important because this is required to remove residual chlorine.

6. When cycle is complete, hang bags to dry. Never let bags sit wet in a bucket or sink for an

extended period of time.

7. If bags do not come out white, repeat operation from step 3.

8. Bags should be replaced after 6 months of daily operation.

5-1. Machine Cleaning

5-2. Bag Cleaning

Power Off and Disconnect all power before cleaning.



1. The first step in cleaning is to disconnect any hand-removable parts and place them in a sink or

set them aside for cleaning and sanitizing, separately.

2. All remaining produce should be hosed off and removed. Avoid spraying water directly at

motors and controls.

3. After all easily-removable debris has been cleaned off, we recommend using a foaming

cleanser to help break down remaining particles. “Masterklean” can be purchased through

customer service, or another product similar to Masterkleen may be used. For information on

the chemical makeup of “Masterklean” please contact Goodnature Products, customer service

(716)-855-3325.

4. Mix up 3 gallons of cleanser solution, as described in the instructions enclosed with the

cleanser, using hot water. Wash down all surfaces taking care to thoroughly clean all areas

that produce has come into contact with.

5. All removed parts can be washed and sanitized by hand in a sink or soaked if desired.

SECTION 6: Maintenance

6-1. Routine Maintenance

Power Off and Disconnect all power before maintenance.


Daily Maintenance:

Keep machine clean and free of any foreign objects.

Apply food-grade grease to the top and bottom of the rail on both sides of the

press. This allows the shims to slide with little resistance.

Weekly Maintenance:

Check all fasteners for tightness and damage.

Inspect press racks for cracks or sharp edges.

Inspect hydraulic lines for damage of leaks.

Check hydraulic fluid level. With the press retracted or in the open position,

remove the breather cap from the hydraulic reservoir. Use a dipstick to check

level of fluid, it should be about 1” below the hole. If it is low, add SAE 10 all

purpose hydraulic fluid. If your system was designed for food grade or

specialty fluid, use appropriate fluid.

Apply food-grade grease to the 3 grease fittings located on the scissor

assembly hinges.

Inspect all nuts and bolts for proper tightness. Critical for proper operation of

scissor assembly.

* Oil Filter– Replace oil filter after first 50 hours then every 250 hours thereafter

(Part# 13867).

11

SECTION 7: Troubleshooting

7-1. Troubleshooting

Power Off and Disconnect all power before maintenance.


Press speed too fast or too slow—Adjust the speed according to section 4-2, speed of

press.

Platen does not move—Turn flow control knob counter-clockwise and try to run the press

back and forth. It is also possible a fuse may have blown; have a qualified electrician

check for electrical fault.

Platen moves erratically or jumps—This indicates oil level is low; check the hydraulic res-

ervoir oil level. Be sure to check this with the cylinders fully retracted.

Press moves too slow— This can indicate that flow control valve is too restricted or is

plugged; Turn flow control knob counter-clockwise to achieve one inch travel per 13 sec-

onds.

Pomace squirts up when pressing—This could be caused from several factors; bags are

too dirty or plugged— clean bags or it may be time for a new set. Bags are too full—keep

the bags 50-75% full. An improper grind—move to larger screen for chunkier grind. Press

speed— usually means it’s too fast. Warm overripe fruit—if possible, cool soft fruit before

pressing. It is often found that using a press-aid will remedy some of these problems.

8-6. Improving Yield

Yield is calculated as a percentage of juice out compared to weigh of produce in. For exam-

ple, a pressing that started with 10.0 lbs. of apples, and yielded 8.0 lbs. of juice would be an

80% yield. It is important to check yield at least occasionally, it can be a useful tool in deter-

mining if pressing should be slowed down, sped up, or altered. Yield should be recorded of

any separate produce or mixture of produce.

%Yield = (Weight juice/weight fruit) X 100

If trying to improve yield, here are a few things to consider:

Not all produce is considered equal. Juice is more difficult to extract from some fruits and

vegetables than from others. Often mixing different types of produce before grinding

helps improve overall yield.

Lengthen press cycle. With few exceptions, slowing down the press cycle will increase

the yield. A fast pressing can cause pathways for juice to seal off in the early stage of the

cycle, making extraction more difficult.

Keep things clean. A clean bag makes for a good pressing. Pectin buildups and other

residues can have a ‘blinding’ effect on the bag, lowering yield. It is a good idea to have

extra bags.

Check on the efficiency of the grind. A grind that is too fine or too coarse can make ex-

traction more difficult. Due to the variation between produce it is important to evaluate

this often.

Enzymes or press-aids can be used.

Temperature of produce is a factor. For instance, apples that have been allowed to par-

tially freeze and then thaw are very difficult to grind and press, and often have low yield.

Quality of produce. Fresh, crisp, clean fruits and vegetables often have the highest yield.
