Dispensing Hot Water
The hot water spout is activated with the right-side actuator. Gently pull the handle
forward to dispense water; return to the upright position to turn off water.
Hot water is drawn directly from the steam tank and its temperature cannot be
manipulated independently. Frequent or heavy use of the hot water spout will result
in reduced steam tank pressure and temperature, causing decreased steaming
ability.
Adjust Flow Rate
Flow rate is controlled by a precision needle valve, which is located inside of the
machine on top of the brew tank. Adjust the flow rate with the following steps.
Parts and tools:
•
Empty 8-ounce (240-milliliter) vessel
•
Gram scale
Procedure:
1. Remove portafilter from grouphead and set aside.
2. Briefly move the brew actuator to the "pre-brew" position, then to the "full
brew" position for a few seconds before returning the grouphead to the "off"
position.
3. Place a container on a scale underneath the grouphead and tare the scale to
zero.
4. Move the brew actuator to the "pre-brew" position; a timer will automatically
begin in the top-right corner of the digital display.
5. When the timer reaches 30 seconds, remove the container and scale, then
move the brew actuator to the "off" position.
6. Weigh the container again without taring the scale to determine how much
water was dispensed in the allotted time.
7. Use this weight to determine flow rate, which is expressed in these terms: x
grams of water per 30 seconds.
‣
Slayer recommends starting with a flow rate of approximately 40 grams of
water per 30 seconds. The actual flow rate may be within a range of +/-2
grams of the desired flow rate.
‣
To decrease the flow rate, turn the blue control knob on the needle valve
clockwise.
‣
To increase the flow rate, turn the blue control knob on the needle valve
counter-clockwise.
IMPORTANT: Over-tightening the valve may break the needle inside. Only adjust
the flow rate incrementally to avoid damage.
