Retrofitting Your Slayer 1.0

support

Dec 12, 2011

Several of our beloved Slayer 1.0 clients have wondered what 2.0 changes they can retrofit to their machine. Well, wonder no longer! Below is a list of all 2.0 retrofittable parts. (If you missed the news about our new Slayer 2.0, jump to that article here.) Not all 1.0 Slayers need all upgrades, so read on to see what best fits your Slayer’s needs. Things to consider include the age of your machine, upgrades already installed, any issues encountered, and the amount of time since your last preventative maintenance repair. We recommend doing preventative maintenance every four to six months, so if your Slayer is due for a PM it may be advantageous to do so with the retrofittable parts listed below.

As with all espresso machine repairs, please be sure to read the Owner’s Manual first. If you own a Slayer and need a copy of the Owners Manual or the Slayer Preventative Maintenance  Manual, please contact us. Important safety information is listed at the beginning of the manual. There are also informative videos in the Preventative Maintenance and Troubleshooting sections to help with repairs and maintenance. Please be sure to watch the important video titled, “Changing the Valve Inserts & O-Rings Within the Group” as well as the link listed on that video’s page to “Bent Needles on the Brew Gauges.” The videos require a password, which is listed in the manual under the Preventative Maintenance section. If you have further questions, get in touch through our contact page.

Valve Stem. Part #1616

Important: Please watch the videos “Changing the Valve Inserts & O-Rings Within the Group” and “Bent Needles on the Brew Gauges” prior to making any adjustments to the machine. These videos contain important information about replacing the valve stem.

1. There are now two o-rings on the top side of the valve stem to prevent leaking through the cap. The lower o-ring has been moved to a lower position on the shaft to ensure that it is always sealing into the group.

2. The valve stem hole is now smaller to prevent the hole from digging out the valve insert seal.

3. The valve stem is now electropolished to ensure it is always perfect and consistent.

Valve Insert. Part #5050 and Valve Insert Seal. Part #5051

Important: Please watch the videos “Changing the Valve Inserts & O-Rings Within the Group” and “Bent Needles on the Brew Gauges” prior to making any adjustments to the machine. These videos contain important information about replacing the valve insert.

We now have a new replaceable valve insert seal. Originally the seal was attached to the valve insert and the whole unit had to be replaced whenever the seal wore out. Now only the custom moulded seal needs to be changed, providing users a cost savings and less waste. Also, the seal is now made of Viton, a significantly stronger material that will last longer than the original silicon seal.

Brew Gauges. Part #5032

New higher quality pressure gauges have been installed that don’t lose their calibration. The insides were previously made of soft copper, but are now made of stainless steel.

Note: The 1.0 Slayers were designed to fit with the gauges installed at that time. To ensure a perfect fit, the insert hole for the brew gauge may need to be slightly filed before installing the new gauges.

Steam Actuator Shims. Part #5315 (thin) and #5316 (thick)

New steam actuator shims have been added so that the shoulder bolt doesn’t come loose over time.

Note: Two thicknesses are used in a customizable combination. Shims come in packs of ten to mix and match as needed to create a secure fit.

Heating Elements

Part Number: 2009 (2 Group Steam Tank), 2011 (2 Group Pre-Heat Tank), 2010 (3 Group Steam Tank), 2012 (3 Group Pre-Heat Tank), 2013 (All Brew Tanks)

New heating elements are now used for all tanks. The new heating elements are the same wattage, but are actually more powerful.

Temperature Probes

New higher quality temperature probes are now available.

Group Cap Wire Cover. Part #1604

A modification has been made to the back of the group cap wire cover, so that the vent tube going to the drain will not be pinched. This should help with the nuisance of pucks sticking to the screen after a shot.

Bayonet. Part #5601

A new stainless steel bayonet has been designed to fit properly with the Slayer group cover. Now there is no gap between the two parts.

Drip Tray Liner. Part #1000 (2 group) and Part #1300 (3 group)

The new drip tray liner has been redesigned with a new reverse slope on the left hand side. This prevents the buildup of coffee grounds
