IMPORTANT SAFETY INFORMATION Newport Brass’s line of 'Hot' and 'Hot/Cold' water dispensers may drip from the spout after use under normal
operating conditions. This condition is caused by the thermal expansion of water that occurs naturally when
cool water is heated in a confined space (the tank). Newport Brass dispensers are specifically designed to
allow steam or expanded water to escape through the spout, thus preventing pressure from building within
the tank. This is a safety feature and should not be confused with a defective product.
Lab tests have confirmed that during the heat up cycle it is possible that up to 5 ounces of water may leak from
the spout for up to 15 minutes after the valve is shut off. The actual amount and duration is dependent upon the
temperature of the water and the amount of hot water dispensed.
Although persistent leaking and/or dripping may also be caused by a non-conforming cartridge and/or
improper assembly, the type of leakage described here can be verified by unplugging the power to the water
heater. Water should not leak through the spout after the tank is shut off in this manner.

Unlike other types of household water heaters this tank is not pressurized as a safety precaution. On
conventional household water heaters the water dispenser valve is placed after the heater tank resulting in a
pressurized tank. In this configuration, the water dispenser valve is placed before the tank creating an “open
vent” style system ensuring that pressure does not built up inside the tank.
This tank can produce up to 60 cups of hot water per hour at approximately 200°F (93°C) ±5°. Due to the
high temperature of the water the tank is not under pressure as a safety precaution. Consequently, there may
a slight delay of water flow after the water dispenser valve has been opened. This is normal and indicates
that the thermo expansion chamber is functioning properly.

Recommended Ground Method
For your personal safety, the hot water tank is equipped with a power supply cord having
a 3-prong ground plug. To minimize possible shock hazard, the cord must be plugged
into a mating 3-prong, ground type outlet, grounded in accordance with all local codes
and ordinances.
If a mating outlet is not available, it is the personal responsibility and obligation of the
customer to have a properly ground, 3-prong outlet installed by a qualified electrician.
If codes permit and a separate ground wire is used, it is recommended that a qualified
electrician determine that the ground path is adequate.
A 110 volt, 60Hz, AC only 15 or 20 ampere fused, grounded electrical supply is required. It
is recommended that a separate circuit serving only your hot water dispenser be provided.
Note: Use an outlet that cannot be turned on/off by a switch. If the supply cord is damaged, it must be
replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
INSTALLATION | Before You Begin
Make sure that the water dispenser is compatible with this hot water tank. Dispenser must be a Newport
Brass branded faucet. Using a standard water dispenser will damage the tank and void the warranty.
Make sure you have all necessary parts and tools as suggested on page 2.
Before connecting to the power source, the tank must be filled with water and the thermostat turned to
the OFF position.
Do not use an extension cord with this appliance. Appliance must be within 36” (914mm) of the power
Plumbing connections must comply with all local codes and ordinances.
Do not use any pipe sealing compounds as they may get inside the tank causing an objectionable taste and
The suitable water pressure range for this tank is from 35-100 psi.
IMPORTANT: Observe all governing codes and ordinances.

STEP 1 - Mount The Tank: The dial must be in the OFF position during installation.
Position the tank vertically beneath water dispenser so that the flexible tube from the water dispenser reaches
the center tube on the tank in the shortest distance possible. Keep the tank at least .4” (10mm) away from the
wall. The back side of the tank can be mounted against the wall. To mount to dry wall, use two mounting
screws and plastic anchors.
NOTE: The tank must be positioned so that the hose to the water dispenser does not twist or kink.
STEP 2 – Install the Water Dispenser
Follow the water dispenser installation manual to install the dispenser to the sink.
STEP 3 - Connect the Water Dispenser to the Tank
Connect the water dispenser to the tank (see Figure 1). Remove the red clips from the quick-connect fitting
(Fitting #1) supplied with the tank. Use this fitting to connect the 1/4” water dispenser outlet tube (red color
hose) to the rear water connection inlet at the top corner of the tank. Push the tube straight into the quick-connect
fitting as far as possible for both connections. Reattach the red clips onto the quick-connect fitting. Use the brass
fitting supplied with the water dispenser (Fitting #3) to connect the ¼” water dispenser inlet tube (clear color
hose) to the center connection outlet on the top of the tank.
NOTE: DO NOT twist or kink the tubes. Tubes may be cut to length if necessary.
NOTE: DO NOT lengthen the tubes. Dispenser performance will be impaired and warranty will be void.
STEP 4 - Connect Cold Water Supply
Remove the red clips from quick-connect fitting with filter screen (Fitting #2) to connect the ¼” water
dispenser supply tube (blue color hose) to the cold water supply source. Reattach the red clips onto from
quick-connect fitting with filter screen.
NOTE: The cone shape of the filter screen should point in the direction of water flow as shown
in Figure 1.
STEP 5 - Check for Leaks
Open the valve in the water line and turn the water dispenser ON (hot side) in order to fill the tank (about 1
minute). When the tank is full, water will flow out of the dispenser spout. Turn the dispenser off by closing
the valve. Check for leaks.
STEP 6 - Prepare for Power
The thermostat control dial should be in the OFF position. The thermostat control dial controls the water
temperature, not the flow of water.
The hot water tank is equipped with a self-resetting thermal fuse. When filling the tank the
thermostat should be in the OFF position before plugging the power cord into an electrical outlet. If
the tank is empty and the thermostat is set to the ON position when the power cord is connected,
the self-resetting fuse will disconnect the current to the heater after approximately one minute in
order to protect the heater from a “dry start” failure. The fuse in the heater control will self-reset
after approximately 1/2 hour. Turn on the water supply to the tank and continue the installation.
Continued misuse will cause damage to the hot water tank voiding the warranty.
STEP 7 - Test Installation
Plug the electrical cord into a grounded 3-prong outlet. Do not use an outlet controlled by an off/on wall
switch. Turn the thermostat control dial clockwise to the highest position. Maximum temperature will be
reached in about 15 minutes at which time the dispenser will be ready for use. Lower the temperature
setting by turning the thermostat control dial counterclockwise if you detect steam vapor or hear a boiling
noise. To raise or lower the water temperature, rotate the thermostat dial accordingly. At the LOW setting
the water temperature will be approximately 140°F (60˚C) ±5° and approximately 200°F (93°C) ±5° at the
HIGH setting.
If the hot water tank is exposed to freezing temperatures the water must be
Unplug the tank from the power supply.
Turn the thermostat control dial to OFF position (fully counter clockwise).
Turn water dispenser on and run water until the water is no longer hot.
Place a 3 quart container under the drain plug at the bottom of the tank. Use a
screwdriver to remove the screw and O-ring in the drain tube opening. When
the tank is fully drained replace the O-ring and screw. Tighten to reseal the

FILTER (Fitting #2)
Clean the quick-connect filter screen if you experience a reduction in water flow.
1. Unplug the tank from the power supply.
2. Turn the thermostat control dial to the OFF position (rotate counter clockwise).
3. Remove the quick-connect from the supply line by removing the red clips from
quick-connect fitting with filter screen and depressing the small plastic ring
around the supply line at the end of the quick connect fitting. This will release
tension and allow the tube to be removed from the fitting.
4. Remove the plastic cap on the fitting with a screw driver by gently prying off the
cap. Next, expose the screen by gently pulling it out of the fitting as shown in the
picture above. Clean the filter screen and cap with a soft brush. It may be
necessary to soak the fitting in vinegar for one or two hours to remove hardened
hard water deposits.
5. Reassemble the quick-connect fitting to the supply line and follow Steps 4-7 of
the installation instructions before using the tank again.
