ECO MAX

Assemble the instantaneous water heater as shown in the illustrations. Observe the information in the text.

Safety information

The instantaneous water heater must only be •
connected and started up by an authorized
technician.

The statutory regulations of the respective country, as •
well as those of the local electricity and water suppliers
must be adhered to.

The instantaneous water heater is an appliance of •
protection class I and must be connected to the
protective earth conductor.

The unit must be durably connected to permanently •
installed lines.

In order to meet the current safety requirements, an •
all-pole disconnecting device must be present on the
installation side. The contact gap must be at least 3 mm.

The instantaneous water heater is suitable for enclosed •
(pressurized) operation only.

The tap fittings must be permitted for operation with •
enclosed (pressurized) continuous-flow heaters.

The instantaneous water heater must only be connected •
to a cold-water pipe.

The instantaneous water heater is suitable for connection •
to DVGW-tested plastic pipes.

The instantaneous water heater must only be installed in •
a frost-free room.

Assembly

I. Unpacking / removing the housing cover

Unpack the appliance and check for transportation •
damage.

Dispose of the packaging and, where applicable, the old •
appliance, in an environmentally conscious manner.

II. Preparation for assembly

III. Wall-mounted assembly

The instantaneous water heater must be fitted securely •
to the wall. If required, secure the appliance using the
lower adjusting screws.

The distance from the wall is variable. This allows you to •
compensate for any unevenness in the wall surface.

The sleeve must fit tightly round the connection cable. If •
the sleeve is damaged during installation, the holes must
be sealed water-tight.

IV. Water supply

The flow-through heater must be vented. Open the warm •
water tap completely and allow to flow through for one
minute.

V. Electric supply

The mains connection terminal can either be mounted •
above or below. At least 40 mm of the connecting cord’s
insulating jacket must be clamped inside the appliance.

Prior to installation, the electric connecting cord •
must be disconnected from the mains voltage and
the water supply cut off!

Only connect the electric supply after the water supply. •

When making holes in the rear wall, only make the •
number of holes required for installation. If the appliance
is reinstalled, any holes that are not used must be made
watertight.

Live components must not be touched subsequent to •
installation.

This appliance must not be used by any person (including •
children) with limited physical, sensorial or mental
abilities or failing experience and/or knowledge unless
they are supervised by a person responsible for their
safety or received instructions about how to use the
appliance.Children should be supervised in order to
make sure that they do not play with the appliance.

VI. Startup

At low water pipe pressure, check whether the MAX •
setting switches on even when water is drawn from
several cold-water taps simultaneously. If not, remove
the flow limiter (refer to additional information A).

Instruct the user with regard to the operation of the •
continuous-flow heater.

Separate the required language version from the rest •
of the operating instructions. This can be kept in the
swingout control panel of the continuous-flow heater.

A. + B. Additional information

If the water pressure of the interior system is low, do not •
operate the instantaneous water heater at full power,
but remove the flow limite (Fig. A).

storage heaters (Fig. B)

請依據後圖所示安裝熱水器，請務必注意相關文字說明。

安全注意事項

·此即熱式電熱水器只允許專業人士進行安裝和調
試。

·必須遵守當地國家有關法律規定以及當地電力供
應商及水務署的各有關規定。

·此即熱式電熱水器屬I類電器，所以必須接上地
線。

·必須將機器接駁在固定之管線系統上。

·為達到有關安全規定起見，安裝端須備有全極的
切斷裝置，觸頭間隙須至少 3 釐米大。

·此熱水器僅適用於封閉式（耐壓式）工作方式。

·接水管的配件必須有許可證，以便被允許可以接
上封閉式（耐壓式）即熱式電熱水器。

·本即熱式電熱水器只可接在冷水管上。

·即熱式電熱水器上可接 DVGW（德國煤氣與供水
專業人士協會）檢驗過的塑膠管。

·即熱式電熱水器只可安裝在不霜凍的房間內。

安 裝

Ⅰ. 拆開包裝，拿開保護罩

·將機器從包裝中拿出來，檢查是否有運輸損失。

·包裝材料應按環保標準去處理（若有不要的舊機
器，也應按環保標準去處理）。

Ⅱ. 安裝前的準備性工作

Ⅲ. 安裝在牆壁上

·即熱式電熱水器應在牆上固定好：若需要，可固
定在下方調節螺絲上。

·熱水器與牆壁間的間隙大小可調整，牆壁上若
有凹凸不平之處可進行調整使機器保持平坦的位
置。

·套管必須緊密地圍繞著接駁電纜。在安裝熱水器
時，如果損壞到此套管，則須把破洞密封好，使
其不透水。

Ⅳ. 接駁供水管道

·安裝前，須切斷接駁電纜的電源，鎖緊供水管。

·供水管接駁好後才可接駁電纜。

·熱水器背面上只有鑽安裝所需的孔洞，若以後需
要另外重新安裝，則須將用不著的孔洞填補且密
封，不讓其漏水。

·安裝好後，帶電部分應是用手觸摸不到的位置。

·必須排盡即熱式電熱水器中之空氣。排氣時先完
全開啟熱水水喉，以讓水流流貫過熱水器，此過
程須持續一分鐘左右。

Ⅴ. 接上接駁電纜

·主電源接駁可安裝在上方或下方。接駁電纜的絕
緣層應進入機器內部至少 40mm 深。

Ⅵ. 啟動

·在水管低水壓且多幾個冷水喉同時開啟的情況
下，請您檢查機器的增強加熱段“MAX”是否會
自動啟動。若否，請您拆除流量限制器（參見附
加說明 A）。

·請向用戶說明即熱式電熱水器的操作方法。

·請將所需的使用說明從使用說明書中撕下來，可
保存在熱水器可翻開的操作面蓋內。

附加說明

·如果建築內水管水壓太低而造成熱水器不能以全
功率工作，則應拆除流量限制器（圖 A）。

·與保溫加熱器並列使用時，此即熱式電熱水器應
