Operation Manual
Model：
EI39G1M(W)
EI39G1M(S)
In case of any abnormality or scorching smell of
the water heater, please cut off the power supply
immediately and contact the service center.
Do not touch the power supply with wet hands, so as
to prevent it from getting wet by water. If it is wet by
accident, it must be inspected and confirmed by the
professional personnel appointed by our company
before reuse to prevent electric shock.
In order to ensure safety, the power supply of the water
heater should be reliably earthed, otherwise, it is strictly
prohibited to use the water heater. The test pencil should
be used to determine whether the live wire and the
neutral wire are connected reversely.
Make sure to use an independent power supply．

Installation guide
Precautions for installation
1. The load-bearing wall for installing the water heater should be able to bear twice the weight of the water
heater filled with water.
. The water heater should be installed indoors and in a non-icing place, with pipes arranged centrally.The hot
2
water outlet should not be too far away from the hot water use point. If the distance exceeds 2m,the hot water
pipe should be insulated to reduce heat loss.
3
.
The water heater should be installed in a place that is convenient for use and maintenance and has a sewer
to ensure that surrounding or lower facilities cannot be damaged when water heater or water pipe leaks. Please
do not install the water heater in a place that can be sprayed directly or is prone to icing.
4. Because of the high power of this water heater, before installing the water heater, please carefully check
whether the ammeter and power wire diameters (2.5mm 2recommended) and fuse meet the rated current and
voltage requirements of this water heater. If necessary, please ask a professional electrician to check the circuit.
5. Do not connect the water-in and water-out pipes reversely; Under no circumstances should the outlet be
blocked.
6. To ensure safety, the water heater should use the standard single-phase bipolar air switch or circuit breaker
(in the case of circuit breaking, the open distance of all contacts should be at least 3mm so as to reliably cut off
the connection with the external power supply during maintenance), and be earthed reliably, with the earthing
resistance of the household earth wire less than 4Ω. Because the water heater requires a large current,the
incoming power supply of the water heater must be directly connected with the air switch, and the power plug
should not be used.

4. Confirm the installation position of the water heater, and drill four φ6X35mm holes on the load-bearing wall
with impact drill, with the spacing as shown in the figure below (it is also allowed to correspondingly locate
the four fixing points by placing the rear shell on the wall). And then, drive four expansion bolts into four holes
respectively, hang up the machine,and fix the machine with screws.

Cleaning
Not used for a long time
If you need to stop using the water heater for a long time, please take the following steps:
1. Cut off the power supply.
2. Close the tap water valve.
3. In order to avoid injuries when the water heater is reused, it is recommended to carefully check
whether all components of the water heater are in good condition and whether the pipes leak by water
supply before turning on the power supply of the water heater.
