THE MANUFACTURER OF THIS W ATER HE ATER WILL NO T BE L IABLE FO R ANY DAMAGES
DUE TO THE FAILURE TO FOLLOW THESE INSTALLATION AND OPERATION INSTRUCTIONS.

CAUTION: BEFORE BE GINNING THE INSTALLATIO N:

A) Turn of f the circuit breaker t o avoid dangerous electr ical shocks.

B) Turn of f the water supply.

1. Remove electrical access cover. Attach conduit to the conduit access hole. Then feed wires. Do not attach wiring.

2. M ount unit horizont ally against the wall so the silver label reads cor r ec t ly ( See Fig. 1) . M ount with four screws
through the flanges located on each corner using molly anchors or fasteners.
CAUTI O N: Heating element s may burn out if not mount ed horizontally.

3. Connect plumbing. Use ¼” tapered national pipe thread at cold wat er inlet and hot water outlet ( See Fig. 1) . Use
compression fittings supplied for ease of installation. Do not apply heat to t hese fitt ings.

4. Run water through the unit to expel all air bubbles. Check for leaks at all fitting joints.

5. Connect wiring. Attach ground wire to center terminal and hot wires to outer terminals (See Fig. 3).

6. Replace electr ical access cover. Turn on the circuit breaker . The unit is now ready fo r use.

7. Local plumbing and electrical codes must be followed in the installation of this water heater and it’s accessories.

8. Failure to comply with code requirement s voids the warranty.

IMPO RTANT NOTES: Air in the heater may cause the element to burn out. If the water lines are drained,

allowing air into the heater, be sure to follow the following start-up procedure:

1. Turn off electr ical supply at circuit breaker.

2. Turn on water supply.

3. Expel all air from lines and heater.

4. Turn on electrical power supply at circuit breaker .

FIGURE 1 HEATER INSTALLATION
Faucet flow controls attached to the faucet allow the water heating system operate more eff ect ively. For example, 2 GPM
flow controls r ecommended for faucets, assure that t he flow rate will not e xceed 2 G PM . However, less water can always
be used. Also, consumers can mix w ith cold water as with a conventional system (See Fig. 2, pg. 3 for I nstallation).

OPERATION INSTRUCTIONS
Turn the hot water fixture to activate the flow switch. The flow switch activates at one gallon per minute (GPM) and

deactivates at .65 gallon per minute.
If y o u incre as e the flo w r a te of t he w a ter will be c o me c o o ler. Co ld water can always b e mixed just a s wit h a co nventional

system if using a t w o handle faucet.
Once y ou dec reas e the flo w r a te t o .65 GPM the unit will deact ivate. I t is not advisable to operat e t he heaters at t he

.65 GPM .
>Periodically ins pect t he supply lines, connect ions and heater for any moisture, corrosion or other potential preventable

problems.
HOW INSTANT-FLOW MICRO WORKS
The cast alloy case houses a series of ingeniously designed c oils that instantly heat wat er as it flows t hrough the vessel. A

unique power sw it ch automatically applies elect r ical current to the coils when hot water is being requested. The electrical
current is not applied when the water is not in us e. The microprocessor is internally preset at t he factor y t o maintain a
constant output temperature with varying flow rates.

OPTIONS/ FLOW CONTROLS
You may want to install the supplied flow cont r ol in your design. This high-quality control makes the water heating system

operate more ef f ec t ively, as well as saving water . The supplied 2.0 GPM flow control assures t hat the flow r at e will not
exceed 2 GPM. However, less water can always be used. Consumers can mix t he cold water as with a conventional
system.

LOW FL O W RATE SYSTEM
For applications where a 0.5 GPM f low r at e is desirable and / or w here only 110 VAC is available, see our low f low r at e
system outlined in Installation Sheet #927.

TROUBLESHOOTING GUIDE

Your Instant-Flow M icro water heater has no int er nal user serviceable parts and should be r et urned to the factor y f or repair
or replacement. Please contact factory for return authorization. If after following the Installation Instructions, your
Instant-Flow Micr o does not heat wat er in accordance with this literat ure, please check the following:

1. Low Power – Verify your voltage by us ing a voltage meter. You should obtain your reading off t he two outside
terminals located on the heater. Compare this reading against t he voltage specified in the
Installation Instructions. The center terminal is always the earth ground.

2. Low Voltage – The percentage of r eduction in voltage will res ult in a lik e reduction in temperature incr ea s e .

3. Check Low Amperage Draw – Check amperage draw using an Amperage Probe. Please compare your
results with the Installation Instruction (Table 1) to determine if the heat er is oper at ing correct ly.

4. Length of Pipe - L engt h of pipe run will affec t t he t e mpe rat ure incr e a s e . The heate r should be mounted no
more the 12-18 inches from the point of use.

5. Check shut – off valve – Check shut- off valve and make sure valve is open 100% to allow full water pr essure
to the heater.

6. Check Flow Rate – Cont rolling f low r a te is es s e nt ial to insure p rope r t emp erature incr e as e . Check y o ur flow
rate t o insure proper operat ion of the heater. Standard Flow Rate M odels require 1.0 G PM to activate.

7. Installation – Heater must b e installed in a horizonta l po s ition. T he silver la b el will t hen be loc a ted in t he upper
left corner as you face the heater.

8. Water Supply – Cold water supply to only feed Instant-Flow Micro cold w at er inlet.

9. Freezing – Instant-Flow Micr o heaters must be drained and stored if in a location subject t o freezing.
Disconnect the inlet/ outlet compress ion fittings and blow air through one side of t he heater to assist dr aining.
Failure to co mple tely r e move water fr o m t he unit w ill r e s ult in f reezing and cr ac k ing.

10. Problems? – Call our t oll-f r ee hotline [phone] or 626-937- 4270.
