DO NOT place the Pot and the Base on a wet
surface.
DO NOT let the Pot when it is hot to get in touch
with a cold surface.
DO NOT place the Pot directly on a gas or
electric cooker or hot plate.
DO NOT pour or spill water onto the Connector.
DO NOT place anything on top of the Brewer.
DO NOT operate the Brewer with a damaged
Power Cord or Plug, or after the Brewer has
malfunctioned or has been damaged in any
manner.

An extension cord may be used if care is
exercised. The marked electrical rating of the
extension cord should be at least as great as the
electrical rating of the Brewer. The extension
cord should be grounding type 3-wire cord. The
longer cord should be arranged so that it will not
drape over the countertop or tabletop where it

Re-insert the Flow Tube back into the Pot.
Re-attach the Filter onto the Infuser, ensuring the
clip on the Filter is properly clipped onto the sidewall
of the Infuser.
NEVER immerse the Pot, Base, Power
Cord or Plug in water or allow
moisture to come in contact with
these parts
Gently secure the Infuser on the Pot. Always ensure
the Spray Cap fits comfortably inside the Infuser
without deformation. Improper positioning of the
Spray Cap will diminish brewing results.
Fill the Pot up to the ‘MAX’ line marking on the Pot
with clean water.

PAGE 10 CLEANING & CARE
Proper cleaning of the Brewer after every use is essential for maintaining the Brewer in its best condition
for tea brewing.
CLEANING THE EXTERIOR
CLEANING THE INTERIOR
Always ensure the Brewer is completely turned off,
the Plug is unplugged and the Brewer has cooled off
for at least 10 minutes before opening the Lid and
Infuser for cleaning.
Clean the exterior surface of the Pot (except for the
bottom of the Pot) with a damp cloth and then dry
with a soft cloth. DO NOT use steel wool pads or
harsh/abrasive cleaners on any parts of the Brewer.
To protect against electric shock,
NEVER immerse the Pot, Base, Power
Cord or Plug in water or allow
moisture to come in contact with
these parts.
DO NOT wash the Pot exterior under
running water.
Note: When pouring out the remain-
ing tea with the Lid opened, water
droplets may come out from the
Spray Cap.
Wash the Lid and Infuser in water and gently clean
them by soft sponge or cloth. Remove the Filter for
cleaning if necessary.
Rinse the inside of the Pot with warm
water and clean it gently with soft
sponge or cloth.When draining all the
water of the Pot, always ensure to
press on the Spray Cap to release any
remaining water in the Flow Tube.
Let the Pot dry naturally. DO NOT turn the Pot upside
down for drying as it may cause glass breakage.
Always ensure the Brewer is cooled off
before opening the Lid for cleaning.
Only the Infuser, Filter, Spray Cap,
Flow Tube, and Sheath are dishwasher
safe.
For a more thorough cleaning, remove the Flow Tube
and run water inside the tube. Squeeze the Spray Cap
to drain out any remaining water inside the Flow
Tube.
Ensure the Sheath is properly wrapped onto the
bottom end of the Flow Tube.
Ensure the Spray Cap is properly wrapped onto the
top end of the Flow Tube before re-inserting into the
Pot.
01
02
Open the Lid. Gently remove the Infuser by grabbing
by the Silicone Rubber Rim. Note: Always hold onto
the Pot Handle when lifting up the Infuser Handle to
prevent tumbling and breakage of the Pot.
03
Always discard wet tea leaves in the Infuser and any
left-over teas in the Pot within 30 minutes after
each brew.
04
05
06

10
Scale may build up in the Infuser, Flow Tube and
Heating Plate. Therefore it is very important that you
descale regularly using a commercially available
descaler to upkeep the appearance, maintain
functional efficiency and prevent appliance failure.
Always follow the manufacturer’s instructions
carefully when descaling.
