Upgrading Your
Hottop Coffee Roaster

  Over the years there have been four models of Hottop Coffee Roasters with variations in the "P" and "B" models. Even with those changes, the basic design has remained quite constant. This allows Hottop to offer upgrade kits which will give older Hottop Coffee Roasters virtually all the benefits and function of the newer models.
  Before considering an upgrade please be aware that some of the upgrades require disassembling the roaster nearly completely. Before ordering please be sure that you are capable of completing the work.
NOTE: In particular, upgrading to the "K" or to "-2" or to "-2K" from earlier models (non -2 and non K models) is quite involved. Please feel free to contact us by E-Mail if you have any questions.

Upgrade Instructions in PDF format

Please use the following PDF instructions which cover upgrading:
FROM KN-8828 and KN-8828D models:

    Upgrade to: KN-8828P-2 or KN-8828P-2K
Upgrade to: KN-8828B-2 or KN-8828B-2K

Specifically, pay attention to step #19a and #19b
Those steps cover important points necessary to allow later
control panels to operate with these two earlier models of machines.

Installation instructions for the following kits:
UK-100, UK-101, UK-102, UK-103, and UK-104
will be found HERE.


How to Use the Upgrade Matrix
1) Find your current roaster model along the top in the lavender squares.
2) Find the model you wish to convert to along the left in the blue-green squares.
3) Where the row and column converge will indicate if the conversion is possible or recommended, and what parts will be necessary.
Example: To upgrade from a KN-8828B to a KN-8828P-2K you would use the upgrade kit, part "UK-102."
Note: To make the matrix easier to read, we have not used the "KN" text in the model designations.

COLOR CODING
The color coding in the above matrix only represents the relative difficulty of each upgrade. Be aware that these "ratings" are of a general nature. You are the best judge as to whether you possess the skills and experience to successfully complete them.

  MOST DIFFICULT - Requires removing all major components inside roaster (eject mechanism, motor, heating element, fusible link, etc.) and disassembling the frame to replace horizontal frame member. Requires good organizational skills.
DIFFICULT- Requires the removal of the roast chambers rear wall. Easier than the "red" level because the frame does not have to be disassembled. Still requires removing nearly all the same components as the red level
SLIGHTLY DIFFICULT - Requires disconnecting all wires on the main circuit board in order to be able to remove the base and replace the main circuit board. Easier than the "ORANGE" level because the major components do not need to be removed.
EASY - This change would only require the switching of the control panel by removing the old one and installing the replacement. Normally would not require any further disassembly.
XPOINTLESS - Not recommended or an unnecessary downgrade. For example, there is no need to go from a "-2" model to one without the emergency eject mechanism.
