WARNING: Disconnect electrical power before removing access panels!
CAUTION: This procedure involves working with hot water and hot surfaces!
A daily routine of cleaning the GEM3IF Satellite will maintain the appearance of the unit and ensure great tasting cof-
fee. To clean the Satellite components, prepare a mild solution of detergent and warm water.
CAUTION – Do not use cleansers, liquids containing bleach, powders or any other substance containing chlo-
rine. These products promote corrosion and will pit the stainless steel. USE OF THESE PRODUCTS WILL
VOID THE WARRANTY.
Cleaning the Gem3IF Satellite
Cleaning the Satellite Server
DO NOT immerse the Satellite in water or any other liquid.
1. Remove lid from Satellite. Clean the lid at the funnel area with a spiral brush and detergent solution.
2. Rinse the lid, removing all traces of cleaning solution.
3. Clean inside of the Satellite. Remove coffee residue with the detergent solution.
4. Thoroughly rinse out the Satellite with clean warm
water.
5. Unscrew the handle/bonnet assembly and remove it
from the dispensing faucet.
6. Inspect the silicone seat cup for wear, cracks, or
hardening. If okay, then leave the seat cup attached
on the handle/bonnet assembly. Soak then wipe
clean. Replace the seat cup if damaged.

gauge glass cap.
8. Clean the gauge glass tube with a gauge brush

the cap.
9. Clean all parts. Thoroughly rinse with clean warm
water.
10. Dry and assemble the parts. Hand-tighten when the
assembling.
Liquid Level Probe
Cleaning intervals for the probe are to be determined by the user or the service tech based on water conditions. The
use of water lters, or the type of water lter that is being used can impact the service interval. Intervals can be from
one month to several years, however, replacing rather than cleaning the probe is preferable.
