SECTION 1: Safety Precautions
IMPORTANT WARNING: To limit electric shocks, per-
sonal injury or material damage due to misuse, please
read these instructions carefully and follow them strictly.
The operation manual should be kept within easy access
for all users and read completely by all first time users of
the machine.
1-1 Safety Precautions
SAFETY GLASSES must be worn at all times during operation, cleaning, and
servicing of the machine.
Never wear loose fitting clothing that can get caught on any moving parts.
Long hair must be worn up and tied back or in a hat or hair net.
Never insert any foreign items into the Pasteurizer that weren’t supplied by the
manufacturer and described in this manual.
Always disconnect power before cleaning or servicing this machine.
If any components are damaged or are malfunctioning, discontinue use immedi-
ately and get the machine serviced.

SECTION 2: Unpacking
2-1 Unpacking
Unpacking Equipment
The equipment has been packaged to reduce the chance of damage during shipment.
After unloading the pomace pump from the common carrier, remove the crate, banding
and shrink wrap to expose the pump for inspection.
Inspection
This equipment was carefully inspected both mechanically and electrically before
shipment. It should be physically free of marks or scratches and in perfect electrical order
upon receipt. The equipment should be inspected for physical damage. Also, the
equipment should be inspected for loose or bare wires. If there are any damaged items
due to shipping, contact the freight carrier. If any parts are missing, please call our
Customer Service Department at (716)855-3325.
Locating the Pasteurizer
The pasteurizer should be in an area with ample room with easy access to all four
sides of the machine.
The location should also be warm enough to prevent freezing from occurring. Freezing
will cause significant problems.
The unit should be in close proximity of the tank holding the raw product and the tank
that will be receiving the pasteurized product.
The unit should be in close proximity to a fresh water supply, fuel source for the boiler,
and electrical supply.
A floor drain in the same room as the machine will provide an outlet for accepting
water used to rinse and clean this equipment.

SECTION 3: Installation
IMPORTANT WARNING: All electrical connections
should be made by a licensed professional in accordance
with state and local codes.
3-1. Installation
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 should be written in on page 2 of this
manual. Can also be found on the serial sticker located on the electric box of
your machine. For help finding this information call Goodnature customer
service. 716-855-3325.
After unpacking and before running, it is important to check that no fasteners
became loose during shipping. Check all nuts, bolts, and screws to make sure
everything is tight.
Some components of your machine were removed at the factory to prevent
damage during transport.
These parts will be in separate boxes with a red tag attached indicating where it
belongs. Match the corresponding letters on the parts to the letters on the
machine.
Attach each part by hand tightening any nuts, bolts or clamps. Once all parts
are connected go back and tighten further with the appropriate tool.
Pump feed: raw product can also be pumped into the machine. It is important
to note that the in-feed level control on the pasteurizer does not shut the pump
on and off, it operates the air actuated butterfly valve only. When choosing a
pump, select a pump that is the same as or greater than the anticipated
pasteurization flow rate or if your pump is oversized install a flow control valve
in the line. An undersized pump will cause plate exchanger fouling. Install hose
or stainless tube between raw product tank, pump, and the inlet of the feed
control valve. Make sure that the portion of this line between the pump and
valve is run above the highest possible product level in the raw tank to prevent

SECTION 3: Installation
IMPORTANT WARNING: All electrical connections
should be made by a licensed professional in accordance
with state and local codes.
3-1. Installation
Pasteurized product outlet (standard): install a flexible hose from the
pasteurized product outlet on the back of the unit that can reach the following:
pasteurized product tank, raw product tank, and to a suitable drain. This hose
should be rated to withstand temperatures up to 190°F (87.8°C) and be chemical
resistant. At start up hose will be placed in the pasteurized product tank. When
flushing the system the hose should be directed to a drain. During cleaning, this
hose should be connected to a spray ball in the raw product tank.
Pasteurized product outlet (with cooling section): the pasteurized product
outlet is located on the front of the machine just above the balance tank. Flexible
hose or stainless tube must be run straight up from product outlet at least 2
inches (5 cm) above the plate packs to ensure that all piping fills completely.
From that point, use flexible hose as mentioned in the previous paragraph.
Pasteurized product outlet (hot-fill): the divert valve will be the product outlet
for a machine designed to hot fill product.
Filling Boiler System: to fill boiler system first make sure that all pipe fittings
are tight and the valves on the pasteurizer heating section are open. You may
decide to install a valve on the welded coupler next to the reducing valve on
the top of the 40 gallon (151.4 L) storage tank to help air removal for filling.
Open the air bleeder on top of the air scoop. Open cold water supply valve and
lift rapid fill lever, reducing valve to an upright position. Continue filling the
entire system until all air is removed and the system pressure is correct. Adjust
pressure if necessary. Place rapid fill lever back into horizontal position for
normal automatic operation and close water supply valve to prevent cold water
from entering an overheated boiler.

SECTION 3: Installation
IMPORTANT WARNING: All electrical connections
should be made by a licensed professional in accordance
with state and local codes.
3-1. Installation
Cooling section (optional): if your unit is equipped with a cooling section it is
the plate pack closest to the electrical enclosure.
Cold water as cooling medium: attach a cold water supply line with a valve
to the lower of the two galvanized fittings on the front of the machine. This
valve is necessary to control exiting product temperature. Run a line from the
higher fitting to drain or collect this water in a tank for other use.
Glycol chiller as cooling medium: place supply line from the chiller to the
lower of the two galvanized fittings. Place the return line to the upper fitting.
Place valves on both fittings for the purpose of servicing chiller or pasteurizer.
Please note: the flow direction of the product through the cooling section is
from top to bottom. Consequently the flow direction of the cooling medium has
to be from bottom to top.
Filler recycling valve: if you are planning on operating the pasteurizer directly
into a filler, then a filler recycling valve is recommended. Place the recycling
valve at the filler reservoir and plumb a line back to the pasteurizer's balance
tank. Connect the recycling valve to a level control in the filler reservoir. This is
so that if the reservoir becomes full the flow is directed back to the pasteurizer
to prevent from having to shut the pasteurizer off (which is not recommended).

SECTION 4: Operation
4-1. Operation
Always start machine with water. If you start the machine with product in it,
the first 10-20 gallons (38-76 L) of product will come out of the machine too hot
and fouling of the plates will occur.
Product containing large amounts of sediment has to be allowed to settle out
or be filtered before going through the pasteurizer
If your unit is equipped with a cooling section, never adjust chiller unit
temperature below 33°F (0.55°C) or freezing of the product will occur.
If while pasteurizing you experience large temperature fluctuations or unit is
diverting, adjust pump speed or adjust boiler target temperature. See
"adjusting pump speed" or "adjusting boiler temperature" sections.
Never adjust pump speed above or below the rated capacity of your machine
during pasteurization. See table below for these rates. Your machine was
factory set for the minimum and maximum. It can be operated anywhere in between those two settings.
Machine type Minimum flow Maximum flow
180 2.2 gpm (8.3 L) 3 gpm (11.4 L)
600 4.4gpm (16.7 L) 10 gpm (37.9 L)
900 8.5 gpm (32.2 L) 15 gpm (56.8 L)
1200 15 gpm (56.8 L) 20 gpm (75.7 L)
