Introduction
Audience
Acquiring a Coffee Roaster
The intended audience for this manual, the S35 Pre-Installation and Site Preparation Guide,
includes customer-side administrators, oor employees, general contractors, facilities managers
and other individuals who are responsible for preparing the site for installation of the roaster.
Preparing for and installing a Loring coffee roaster requires cooperation between the customer
and Loring over several weeks. Generally, the customer should begin preparing the site 3 months
prior to shipping. Upon receiving the roaster, the customer’s general contractor assembles
the roaster, connects the utilities including water, gas, and electric, connects the hot and cold
exhaust ventilation, and then waits for the Loring Field Service Technician to perform nal system
commissioning. The commissioning period also includes hands-on customer training in the use and
maintenance of the roaster.
Some tasks, such as ordering stack ventilation components, may require specifying and purchasing
equipment from third-party suppliers. Allow sufcient lead times.
WARNING: Operating the roaster prior to nal inspection and commissioning by an
authorized Loring Field Service Technician will void the warranty.

Additional Documentation
The following additional documentation is available to aid with installation and setup. Contact your
Loring Account Representative for more information.
• Welcome Packet. The Welcome Packet contains detailed instructions and information sent
by Loring to each new customer upon purchase of a coffee roaster. One item, the Product
Specication Form, must be completed and returned to Loring in order for Loring to begin
building the roaster.
• Product Specication Form (PSF). The customer must provide information to Loring
regarding the site’s utility characteristics. This information is used to congure the roaster at the
factory, a process that requires several weeks’ lead time. Loring strongly recommends working
with a licensed professional contractor when providing this information. This form is included in
the Welcome Packet.
• Suggested Stack Manufacturers. One of the items in the Welcome Packet is a list of
recommended manufacturers of stack ventilation components. Loring recommends ordering
stacks 6 weeks prior to the arrival of the roaster.
• Installation and Assembly Guide. After receiving the coffee roaster, the customer must
engage with a licensed general contractor to assemble, position, and hook up the roaster to
various utilities and stack ventilation.
• Mechanical Interface Control Documents (MICDs). These technical drawings provide
detailed information on system dimensioning and components, as well as system weights. They
are intended for permit submittals and for use by general contractors, as well as by architects
and facilities planners. These drawings are available upon request from Loring.
• Special Reports for Permitting. Additional reports on various technical subjects are
available from Loring. Each customer may need to satisfy unique local or regional regulatory
requirements. For example, air quality reports are typically required, and some locations may
require both county and city permits.
The Product Specication Form (PSF) conveys extremely
important customer information regarding the customer
site’s power supply voltage and network conguration.
Loring requires this form to be completed by the customer
a minimum of 9 weeks prior to production completion.
Any delay in providing any portion of this information can
delay the roaster production by a corresponding number of
weeks.

Power Specication
Loring coffee roasters can be built to accommodate a wide range of electrical congurations. To
determine which Loring topology matches your facility’s supply, the customer should engage a
licensed electrician to perform a site survey, in order to provide the following information:
On the Product Specication Form, the customer has the option to choose among some commonly
occurring congurations. However, the customer should NOT approximate by choosing the closest one
if it is not an exact match.
If the customer site is not represented, contact Loring immediately for other possible congurations.
For example, a typical U.S. installation might be 208 VAC, 3-phase, at 60 Hz.
This equates to a specication of 208 (3P) - 60
A typical installation in Europe might be 400 VAC, 3-phase, at 50 Hz.
This equates to a specication of 400 (3P) - 50

The information under Power Specication is as follows:
• Voltage: Designates the type of power voltage at the site.
»The L-L number is the Primary or Line-to-Line voltage.
»The L-N is the Secondary Line-to-Neutral voltage. A Neutral wire is no longer required for
Loring Roasters.
• Number of Phases: The Number of Phases represents the number of Line-to-Line phases.
This is either 1P or 3P, indicating single phase or three phase respectively.
• Wiring Topology: The type of circuit. Refer to Loring Engineering Document No. 1001163 for
more information.
»Y= Wye
»D= Delta
• Power Frequency: The last informational block designates the site’s voltage frequency, in
Hertz (Hz).
In order for the roaster to function properly, the customer is responsible for installing service to the
required level of amperage as follows:
• 200 VAC – 240 VAC:
»1P – 40 Amps
»3P – 30 Amps
• 380 VAC – 480 VAC – 20 Amps
