Special Caution
1. CAUTION
This water heater is for household use only and it can be installed indoors where
hot water is needed.
A plug is not used for this water heater; this water heater must be connected directly to a
circuit breaker with current leakage protection.
Please distinguish live line (red/brown),neutral line (blue) and earth line (green/yellow)
during installation.
Do check whether the ampere rating of the household wiring is sufficient before installation,
and a dedicated circuit must be used when installing.
Before installing this water heater, check and confirm if the earth electrode in the socket is
reliably earthed and has no current flowing. If there is no ground electrode or incorrect ground
connection is done, the water heater will not work.
The hot water from the water heatermay cause scalding; please test and check the
temperature of the hot water before use.
The distance between water heater installed and water output should be as near as
possible to avoid loss of heat.
The electic water heater maybe damaged if the water hardness is too high. To ensure
longer product lifespan, please install nd put it into use where the local water hardness
is less than 450mg/L9CaCO3).
In times of lightning/thunder, switch “Off” the circuit breaker ahead of time, to protect
the water heater against possible damage.
Inspect the built-in ELCB (once a month)to avoid hazards to users such as damage to
property serious injury or death.
Do not cut off power supply before maintenance. Any maintenance or adjustment of
product by a non-professional is highly prohibited.
The damaged power cord must be replaced by good one provided by the manufacturer,
and the replacement should be done by qualified technician or engineer or professionals of
similar products.
In order to avoid hazard due to inadvertent resetting of the Earth Leakage Circuit
Breaker (ELCB), this appliance must not supplied through an external switching device, such
as timer or connected to a circuit that is regularly switched “On” and “Off” by the utility.
This water heater is equipped with adjustable flow capacity safety valve. For safety use,

Connect the wire of measuring instrument according to the manual. Please check the diagram
below.
Connect E1to the ground wire, and connect E2, P2 to the auxiliary electrode of steel bar in the soil
or ground. The distance of E1, E2, P2 and steel bar should be greater than 20m. A requirement is
that the measurement site should avoid strong electric elds, in order to reduce the measure-
ment error.
There are 4 terminals E1, E2, P1, P2 on grounding resistance measuring instrument. E1 and P1 are
usually connected for convenience. You only need to connect the E1 to the ground terminal and
E2, P2 to the auxiliary electrode steel bar in the soil/ground.
If there is no soil to drill the steel bar in, you can connect P2, E2 to the neutral terminal re hoses
or oors, which can be considered as the ground resistance.
Then press the POWER button, select the appropriate test range (if not clear about the scope of
the resistance, choose the biggest range, and then choose the smallest range.), press the PRESS
key. The screen display number is the resistance value of grounding resistance of the house.

4.3 To Adjust Water Flow
4. USAGE
Rotate the handle of water flow adjusting valve.
4.4 Electricity Leakage Protection
4.5 To Adjust Water Temperature
4.7 Use After Overheating Protection
4.6 To Activate Pump Function (FP-67WTR380WMTH-B1)
When the water heater is working normally, press TEST button. If the leakage
test circuit has no problem, the ELCB green indicator light will be off, and the
unit will not heat. Press RESET, testing will be canceled, and the ELCB green
indicator light will be on. The unit will then be back to the working state set
before. If the circuit leaks, pressing the RESET button won’t cancel leakage
testing. The ELCB & POWER indicator lights will flicker, meaning the water
heater has problems and cannot be used. All buttons won’t work, there will be
no heating and the pump will not function.
The pump will be on as the default setting when the product is used the rst time and can be turned o by
pressing the PUMP button which turns this function on and o.
When the electricity leakage testing circuit is working normallyand if the leakage current is bigger
than a value between 7.5mA and 15mA, the red POWER and green ELCB indicator light will be off
with no heating; it can only be used after the failure is solved.
Rotate the handle of water flow adjusting valve to adjust to proper water flow. Adjust power by rotating
the knob clockwise or counter clockwise and the water temperature will increase or decrease
accordingly.
NOTE
For first time use, ensure that the power is turned on only after the unit is filled fully with
water and there is stable water flow coming out of the shower head.
The electric water heater may be damaged if the water hardness is too high. To guaran-
tee the normal service life, please install where water hardness is less than 450mg/L
(CaCO3).
If the water flow is low and power is high while using the unit, outlet water temperature will be high and
the unit will stop heating automatically. At this time, please lower the power and increase the water
flow in order to avoid inconsistency of water temperature.
