IMPORTANT NOTES:
1.
We recommend a metallic brass drain, tailpiece and p-trap as plastic (PVC) cannot withstand
temperautres greater than 140 °F.
2.
Do not solder any pipes with the unit connected to pipes – heat from soldering may damage the flow
sensor. Doing so will void the warranty.
3.
This automatic tankless water heater is equipped with both computer-controlled and electro-
mechanical auto resetting thermostat switches for high-limited temperature protection. Since this
product does not use a storage tank, the use of a temperature pressure relief valve (T&P) is not required
for most installations. UL Standard 499 does NOT require that a pressure relief valve be used. However,
a T&P valve may be required to meet installation codes in your area. If one is required, install the
pressure relief valve in accordance with local codes and ensure that it operates correctly and that air is
purged from the valve prior to installing the water heater. When connecting to Flex or High
Temperature CPVC pipe, we recommend that a T&P valve be used for added safety.
Please note: Installations in the Commonwealth of Massachusetts and State of Kentucky require a
pressure relief valve. Please check your local installation codes for any special requirements.
4.
The maximum system water pressure is 150 PSI (1035 kPA). Minimum operating water pressure 35 psi.
Optimum operating water pressure 45 to 80 psi. If the water pressure is higher than 80 psi, a pressure
reducing valve must be installed on the main incoming water supply line prior to installing the electric
tankless water heater.
5.
Only install the proprietary hot water tube that is included between the dispenser and heater. During
installation, it is recommended that when connecting the inlet water pipe to the unit, make sure to use
a wrench to hold the unit’s connection, and another wrench to tighten, so that the flow sensor on the
unit will not be loosened or damaged. Serious internal damage to the water heater can occur if the inlet
or outlet connections are over tightened or if solder connections were made.
6.
We recommend that a manual shut-off valve is installed on the inlet of the water heater so that there is
a convenient shut-off point available in the event that future maintenance or servicing is required. This
valve will aso be used to reduce the flow rate if necessary. It is extremely important to flush the lines to
eliminate all plumbing paste or residue in the lines caused by any welding or soldering before
connecting pipes to the water heater.
We recommend that all the water pipes or hoses within 3’ (1m) of the inlet and outlet connections be rated for
high temperature applications with a 150°F (66°C) minimum.
CAUTION
Do not use pipe dope or Teflon Tape on any compression fittings on the unit or outlet hot water
tube. Doing so may cause serious safety hazards or increase the risk of leaks.
WARNING
CHECK FOR LEAKS BEFORE PROCEEDING TO ELECTRICAL INSTALLATION
WARNING
This product is not reccomended for anything besides its intended use as described
in these instructions. Attachments not recommended by the manufacturer can cause safety
hazards.
WARNING
VERIFY THAT YOUR GARBAGE DISPOSAL IS CAPABLE OF WITHSTANDING TEMPERATURES UP TO
200°F PRIOR TO DISPENSING THE HOTMAX INTO ANY DRAIN EQUIPPED WITH A GARBAGE DISPOSAL
