Optional Stainless Steel Housing
Chromium provides for an invisible film that resists oxidation, thus making the material resist corrosion or "passive".
Stainless steel, having a non-porous surface, practically eliminates bacteria growth and other harmful micro-organisms. Easy to clean that's why it's the first choice in laboratories, hospitals as well as food processing.
Stainless steel has a modern and attractive appeal and is easy to maintain.

Coffee Shops -- Espresso machines utilize the preset or thermostatic control feature to keep water at a consistent temperature for beverages. Compact size is great for small spaces. Lead-free certification means water is safe for consumption.
Lower utility costs for low income housing -- Chronomite tankless water heaters are 99% more energy efficient than other tank heaters because they are only operational when hot water is streaming through the plumbing. This dramatically reduces hot water delivery time and saves electricity. In warm climates that do not require much of a temperature rise, hot showers are available for a low price.
Guest Houses, Luxury Suites, and Kiosks -- Chronomite's space-saving tankless water heater design is easily concealed at point of use--perfect for small sinks, wet bars, dishwashers, and small areas where space efficiency and aesthetics are important. Remote hot water is even possible for mobile carts in stadiums, amusement parks, and recreation areas.
Emergency safety equipment -- In times of fire, chemical or health risk, water is delivered instantly and at a safe temperature. Drench showers, eye washes, and hoses benefit from a preset temperature and a two-second delivery time. Additionally, the element assembly of a Chronomite heater uses the flow-through abrasive action of water to create a self-cleaning feature that prevents calcification and alkali buildup. Water heater units perform the first time, every single time.
Mop cleaning areas -- Instant hot water delivered conveniently in two (2) seconds, at a temperature that is preset for proper cleaning.

10 easy steps to installing your Chronomite
Remember that proper installation and maintenance of your instant water heater can optimize its energy efficiency and lifespan.
- Before starting the installation, turn off the breaker and disconnect the electrical supply to the area. Shut off water supply to the fixture. Double-check that everything has been turned off before proceeding.
- Access electrical connections in the unit by unscrewing and removing the front face plate. Keep screw in a safe place.
- Mount the unit in preferred location using heavy-duty metal screws, make sure to pull existing electrical wires through supplied hole at the back of the unit. Each of its corner has a mounting bracket.
- Connect electrical supply wires to the electrical connections from the unit. Make sure to securely tighten all connections.
- Close the front face-plate. Screw securely to close.
- Connect the Cold Water supply line from the water source to the bottom Cold/Hot inlet compression fitting opening on the unit. Chronomite Tankless Water Heaters require only one cold water intake. No need for excess lines.
- Connect the Hot Water supply line from the top Cold/Hot inlet compression fitting opening on the unit to the sink.
- Reopen water supply line to the unit. Turn on sink for 2 to 3 minutes to purge air from the lines (Note: water will not run at temperature until the breaker is turned back on in step #10).
- Screw the Flow Control Valve (supplied) onto the faucet/fixture head. An included adapter may be used for an exact fit (each box includes all necessary adapters).
- Once purged, turn on your breaker. Enjoy your new Chronomite Tankless Electric Water Heater at temperature.
Frequently Asked Questions ("FAQ")
I want to install the Chronomite heater in a vertical position.
Chronomite Tankless Water Heaters are built for horizontal installation. When properly installed, the heater will have the inlet and outlet on the right side of the unit when you are facing it. Installing vertically will risk a burn out of the heating coils and the heater will not be covered by warranty. Please refer to the Installation and Operation sheet for the water heater model you are installing.
I want to plug my Chronomite water heater into a wall outlet. Where is the plug?
Chronomite Tankless Water Heaters are UL listed. This means that the heater is required to be "hardwired" to a dedicated breaker. To gain optimum performance and keep the product under warranty, it must be installed in this manner. Please refer to the Installation and Operation sheet for the water heater model you are installing.
How do I decrease or increase the water temperature flowing out of my Chronomite Tankless Water Heater?
The SR Series heaters do not have a temperature adjustment. The SR models are designed to provide a predetermined temperature increase to the incoming cold water. The "M" series models (shown in the Related Gadgets tab above) can be factory preset for consistent, heated water temperature.
The hot water maximum flow rate is significantly reduced from my M40L/240. The cold water at the sink has good pressure and flow, but hot water seems like about half that. All of my valves are wide open. Does the M40L have an internal flow restriction?
None of the Chronomite heaters (including the low-flow models indicated by an "L" in the model number) have any internal flow restriction. But the SR and M series models have 3/8" water connections, while most household water supply pipes are 3/4" (twice the size and flow rate).
May I install my Chronomite tankless water heater outside?
Chronomite Tankless Water Heaters are subject to freezing. For outdoor installation, it is recommended that the heater be installed in an enclosure to prevent exposure to the elements. The heater should also be winterized like any other outdoor product that uses water.
Why is my heater tripping the breaker?
Confirm first that the heater has been hardwired to a non-GFI, dedicated breaker. Then check that the breaker size is appropriate for the heater being installed (Example: If it is a 30-amp water heater, a 30-amp breaker is necessary). Please refer to the Installation and Operation sheet for the water heater model you are installing.
Can I install my Chronomite Tankless heater in the ceiling?
Chronomite Tankless Water Heaters are built for point-of-use applications. For optimum use and performance, they should be installed within 18" from the point of use. Please refer to the Installation and Operation sheet for the water heater model you are installing.
Will a Chronomite Tankless water heater supply my whole house?
Chronomite Tankless Water Heaters are built for a point-of-use application. They are not built to provide hot water to a whole house.
What voltage is my heater and is it okay if it doesn’t match?
Chronomite Tankless Water Heaters are volt specific. For optimum performance and use, as well as to maintain warranty, the heater must be wired for the correct voltage. The voltage can be found on the label that is adhered to the unit's front.
What phase are your heaters?
Chronomite Tankless Water Heaters are single phase.
What size copper or flex tubing do I use?
3/8"OD as per installation instructions.
Are compression fittings supplied with the heater?
Two (2) compression fittings are supplied. They are 3/8" x 1/4" NPT.
What is the maximum operating temperature?
It is 140ºF in compliance with the Underwriter’s Laboratories listing.
Do I need the electricity applied to the heater to know if the heater will turn on?
Chronomite Tankless water heaters are pressure and flow activated. Turning on the faucet will enable the flow switch to make a faint click sound, with or without electricity.
Are Chronomite heaters ASSE 1070 certified?
ASSE 1070 is a mixing valve code pertaining to water temperature limiting devices. It is designed to limit incoming ultra-high hot water supply temperature (120°F - 180°F) to normal, tempered water temperatures (105°F - 110°F), to minimize scalding risk to the end user. Instantaneous water heaters cannot undergo certifications nor testing to this standard, since Chronomite heaters are built to heat incoming cold, ambient supply water only. As stated by American Society of Sanitary Engineering (ASSE) on their official letterhead, the ASSE standard is for water temperature limiting devices, and the various test procedures of this standard requires that the device must have a hot water inlet, a cold water inlet and a mixed water outlet. This standard is therefore not applicable to instantaneous electric water heaters and as such cannot be subjected to ASSE 1070 tests. We have a letter from both IAPMO and ASSE stating these facts on their respective letterheads. Chronomite has a list of manufactures that are certified for ASSE 1070; the good news is, not a single water heater company is on the list. Of course, the Instant-Temp models and Instant-Flow Micro utilize a microprocessor technology that allows for field-adjustable temperatures or factory preset, and can therefore be deemed as having an "anti-scald feature."
