STEP 1 – PREPARING THE HOT TANK
IMPORTANT: Turn Hot Switch OFF before proceeding.
Dispense 1-2 gallons of water from hot system to cool hot tank, then
drain all water from the hot tank. Draining will require an

Remove top and left side panel by removing 4 screws that hold
panels to frame.
Unlock the red hot tank latch by pulling tab out
Remove hot valve by pulling straight up
Remove overflow assembly by turning assembly counter-clockwise
and pulling straight up
NOTE: Some water may leak from bottom of overflow assembly once

STEP 2 – ADDING DESCALING SOLUTION
Fill squeeze bottle with desired descaling concentrate or solution
in recommended volume and pour into overflow hole in top of
hot tank.
Reinsert overflow assembly, rotate clockwise
Replace hot valve and lock red hot tank lock.

(Do NOT yet turn hot switch ON). This will fill the remaining volume
with water and provide the proper solution mixture.
STEP 3 – DESCALING AND FLUSHING
Once Hot Tank is COMPLETELY FILLED with solution,
turn Hot Switch ON.
Allow 15 minutes for solution to heat and remove scale build-up.
After 15 minutes, flush the Hot Tank by dispensing 6-8 gallons
(22-30L) of hot water.
