SAFETY INFORMATION

Prior to installing and operating your roaster, please read the entire manual. If you see this symbol in the manual, make sure to read what follows because it is a caution for actions that can cause harm or damage to your machine and/or the operator.

Death, injury, or property damage can be caused by improper installation, adjustment, alteration, service, or maintenance. The entire installation guide must be read prior to installing, cleaning, operating, or servicing this roaster.

It is the owner's responsibility to ensure the installation, cleaning, and operation of the roaster are done safely and properly. Only a qualified professional should operate this roaster.

Keep any flammable items, including but not limited to gases, vapors, liquids, and solids, far away from the roaster at all times. The roaster needs to have a fire extinguisher nearby and easily accessible in case of fire. Your local fire department will have information on which fire extinguishers should be used. Fires may be caused by not cleaning the roaster or exhaust system correctly and/or often enough.

The roaster needs 18 inches of space around it at all times. Do not touch hot surfaces.

Once the installation of the roaster is completed, you will need to have it inspected to ensure it complies with local building codes. A local fire inspector must also inspect the machine. These steps must be completed before operating. The Primo Roasting Equipment warranty may be null and void if the inspections are not done. This would relieve Primo Roasting Equipment from any liability related to the use of the machine and how the installation was done.

Instructions for what to do when the roaster operator finds a gas leak and/or smells gas need to be posted in a location that is easily accessible and readable. Your local gas company or the company that supplies gas will have the instructions for you to obtain from them.

THINGS TO CONSIDER

i. Ease of movement

ATTENTION: Prior to moving the machine and/or cyclone, make sure the roaster is turned off, unplugged, and the gas is disconnected or turned off.

To move the roaster and/or cyclone, the machine must be taken apart.

1. Remove the exhaust arm by pulling it off via compression fittings and set it aside.
2. Unbolt the cyclone from the ground if applicable. (1) Use a forklift to pick up the machine from the back. *Make sure to tilt the forklift back once the roaster is lifted to avoid it sliding off or tipping the forklift.*
3. Place the roaster in the desired location using the installation guide and spacing requirements.

Make sure to leave ample room behind the machine to allow the forklift access for movement purposes.

*Every time the machine is moved, disassembled, and put back together, the operator must inspect the machine prior to resuming operations.*

PRE-INSTALLATION

i. Receiving/Un-Crating

ATTENTION: Hire a professional to install your roaster.

Roaster:

The roaster comes in a crate.

Cut plastic walls off to expose roaster.

*Be careful not to drop/slide the tool you are using to cut into the crate, on the roaster*

Once all walls are taken off, cut the steel cord strapped over the cooling tray to the pallet.

After the roaster is free standing on the pallet use forklift to move off of the pallet.

Pick up roaster from the back of the machine to get off of the pallet

*Make sure to tilt the forklift arms up once roaster is in the air*

*We recommend keeping the roaster as close to the ground as possible when moving*

Set roaster in desired area *Spacing requirements further down*

Cyclone:

The cyclone comes bolted down on a pallet, wrapped in plastic.

Remove plastic wrap from cyclone & pallet Move pallet as close to desired position for the cyclone to make moving it easier.

*Use spacing requirements further down*

Remove bolts from cyclone legs.

Pick up cyclone using forklift in-between the cyclone legs.

*Wrap and protect the forklift arms/cyclone arms to prevent abrasion on the cyclone when moving*

Place cyclone on correct side of roaster using spacing requirements below.

Spacing Requirements:

Be sure you have ample access to the green bean funnel, control panel, access doors, chaff bin, hopper, etc.

Space your roaster about 18" from back wall to ensure you have ample access for venting the machine.

The footprint of the roaster and cyclone is 90" x 80" x 78". The cyclone needs to be placed 12" to the right of the roaster. The cyclone vent should be flush with the roaster vent to make adding the exhaust arm simple & easy. There must be easy access to the following areas: cyclone chaff bin, left and right side access doors, control panel, hopper, and gas line connection located on the back of the machine. Having easy access to these places will make cleaning and maintenance much easier.

INSTALLATION

ATTENTION: Hire a professional to install your roaster. This manual must be read completely through prior to any installation. Check with local building authorities for their local codes & installation requirements prior to installation.

i. Electrical

ATTENTION: Use a licensed electrical company when installing the electrical on your Primo roaster.

Consult your licensed electrician to ensure proper installation of either the 110 V or 220 V, based off requested voltage. If using 220v a 3 prong 220v will not be included and must be wired to the 3 wires from the machine.

ii. Gas

ATTENTION: Use a licensed gas company when installing the gas line on your Primo roaster.

Local codes, regulations, and/or laws must be followed when doing the gas installation for the machine.

*Propane roasters must use propane only and are required to use a gas regulator. *Have a certified gas worker inspect and double check any gas connection work you do.*

iii. Roaster Funnel & Cyclone Exhaust Fitting

1. Remove a total of four nut caps (7/16") from the hopper.
2. Place funnel slide gate in designated position on top of the hopper.
3. Place green bean funnel on top of the funnel slide gate.
4. Before tightening the green bean funnel to the hopper ensure that your funnel slide gate is operating smoothly. (Slide gate should move with ease.)
5. After the slide gate and green bean funnel are in position you may begin tightening the four nut caps using a (7/16") wrench.
6. Finally, slide the exhaust on, connecting the roaster and cyclone via compression fit.

iv. Cyclone

ATTENTION: When installing the cyclone to your roaster use a licensed contractor.

The cyclone uses 6" ducting to vent.

Consult your licensed contractor to ensure proper installation of duct work.

EXHAUST DUCTING & GENERAL INFORMATION

1. Throughout the remainder of this document, the term exhaust ducting refers to the ducting that the customer, or their contractor/representative, select, acquire, and install. The exhaust ducting will connect to the applicable Primo Roasting provided equipment.
2. One of the most important aspects of the equipment installation is the use of an approved exhaust ducting system. Its design can greatly affect the equipment performance and the product quality. The cost and time to order and install the exhaust ducting are also important customer considerations.
3. Designing the exhaust ducting system requires a qualified professional to calculate the efficiency of the system and the proper size of ducting. The ducting must be of sufficient diameter to accommodate the air flow (SCFM - standard cubic feet per minute or SCMH - standard cubic meters per hour), and meet applicable regulations. A licensed engineer or Heating, Ventilation, Air Conditioning (HVAC) professional can assist. Information the qualified professional will need, such as the diameter of the exhaust ducting and the maximum exhaust air flow, is located on page 3 Technical Data table. Customers should contact their sales or project manager representative with any questions.
4. A properly designed and installed chimney and rain cap is essential to the equipment performance and longevity. Water leaking in may cause an electrical short or damage the equipment. Your contractor will be able to coordinate with local jurisdictions for the correct cap. The cap should not have a screen since it will clog with residue of chaff over time.
5. The Primo Roasting Equipment (roaster, cyclone, Afterburner, loader, or destoner, as applicable) MUST NOT support the weight of the exhaust system.
6. The exhaust air from Primo products fits into one of the two general categories. Either hot exhaust air, such as from the roaster or an afterburner; or ambient/room temperature exhaust air, from products such as loaders and destoners. The sections that follow will discuss ducting considerations specific to these general categories.

EXHAUST DUCTING, HOT AIR - ROASTERS & AFTERBURNERS

1. The exhaust air from the roasting process is hot and contains oils and residues which are flammable. In the event of a ducting/flue fire, the internal duct temperatures can exceed 1000°F (538°C), which could cause nearby combustible materials to ignite. Thus, Diedrich recommends, at a minimum, stainless steel, double wall, positive pressure grease ducting that meets the applicable region/local standards, such as UL for USA, ULC for Canada, and CE for the European Union.
2. An important consideration when designing an exhaust ducting system is the static pressure. The static pressure is the back-pressure or suction within the system. The exhaust ducting that connects to the roaster, cyclone, or afterburner, must be designed to operate with a static flue pressure between negative 0.15"WC (suction) and positive 0.25"WC (back-pressure) at the exhaust of the roaster (cyclone or Afterburner, as applicable) while in operation.
3. For Roasters (with or without cooling bin cyclone, and without an Afterburner).

Ducting must be suitable for 500°F (260°C) continuous, 2,000°F (1,093°C) for 30 minutes, and comply with UL-1978/ULC-SC662 Standard for Grease Ducts in the USA/Canada, and/or equivalent standards for other countries (such as CE standards for the European Union).

Installation must be done in accordance with appropriate NFPA standards in the USA or equivalent standards in other countries. The installation must also comply with the manufacturer's installation specifications and allowable distance to combustible/noncombustible materials.

1. For Roasters with an Afterburner.

Ducting from the Afterburner must be suitable for 1,000°F (538°C) continuous, 1,400°F (927°C) intermittent, and comply with UL103/ULC_ORD-C959 in the USA/Canada, and/or equivalent standards for other countries (such as CE standards for the European Union).

Installation must be done in accordance with appropriate NFPA standards in the USA or equivalent standards in other countries. The installation must also comply with the manufacturer's installation specifications and allowable distance to combustible/noncombustible materials.

EXHAUST DUCTING, AMBIENT AIR -LOADERS & DESTONERS

DANGER DO NOT USE CLASS B OR SPIRAL-WRAP DUCTING FOR ROASTER OR AFTERBURNER DUCTING UNDER ANY CIRCUMSTANCES.

DANGER Fires are caused by failure to maintain a clean roaster and its exhaust ducting system. Regular cleaning of the roaster and exhaust ducting will prevent the buildup of residues that could cause fire.

1. The exhaust air from loaders and destoners is about the same temperature as the ambient air in the room or operating area. The regulatory requirements for the exhaust ducting for these components are much less stringent than the requirements for the hot air roaster, cyclone and afterburner exhaust.
2. The exhaust air from the green bean loader and the destoner will likely contain some dust and/or other particulate matter. A dust collection system should be considered.

OPERATING MACHINE

Primo Roasters have 3 or 4 switches depending on model. The switches in order from left to right: Ignition (IGN), Drum (DRUM), Cooler (COOLER), & Agitator (AGT). Every Primo Roaster is outfitted with a LCD screen. This LCD screen shows your current drum temperature, Temp 1 & Temp 2 set points, and your Burners switch (ON/OFF).
