Dispensing Hot Water 
(HC3300, H3300)
Dispensing Cool Water 
(HC3300)
Scalding Hazard: The faucet dispenses near-boiling 
(212ºF) water which can instantly cause scalds or 
burns. Use care when operating this appliance.
Property Damage: Do not extend the lines farther 
than the 16” provided. Ensure tube(s) and “Y” 
connector are securely fit.
Personal Injury: Do not locate filter above an outlet or other 
electrical device. Install head and bracket so that connections  
require no stretching, kinking or pinching of tubing.
It is normal for approximately 2 oz. of water to 
discharge when filter is removed.
Property Damage: Tube runs need to form to the cabinet’s 
contours to allow storage space with no sharp bends. Tubes 
need clean, perpendicular, burr-free cuts to ensure a true fit.
a
   Determine length of tubing required, 
then cut to length making sure the cut 
is perpendicular and burr-free.
   Insert a white 3/8" tube into inlet side 
of filter head until it stops. 
Press in again to ensure a secure fit.
   Insert the other white 3/8" tube into 
outlet side of filter head until it stops. 
Press in again to ensure a secure fit.
   Mark hole locations for filter head 
and bracket in a spot that allows  
for filter replacement.
   Drill 1/8" starter holes and attach bracket 
to wall with wood screws, turning until snug. 
   Remove red filter cap, insert filter 
cartridge into filter head and twist 
clockwise until “LOCK” arrow on the  
filter aligns with arrow on bracket.
   To redirect filter replacement water 
discharge, place 6" clear tube over
vent hole on the left side of filter head.
   Note: 3/8" fitting is required to make 
connection to water supply.
   Connect remaining white 3/8" tube to 
incoming water supply line. 
(See Step 6.)
   Insert the copper tubes(s) from the 
dispenser into “Y” quick-connector 
using the plug for hot-only models.
