Positioning
Water heater should position near water tap of use in order to minimize heat loss and defects.
For wall-mount installation, appropriate anchor screws must be used, and wall should be strong
enough to withstand the weight of water heater. Installation position should keep a minimal
distant between the wall and water heater.
Connecting P&T Valve and Inlet/Outlet Pipes
The Temperature & Pressure Relief Valve ( P&T Valve) has applied in water heater, when
the temperature/ pressure in water heater is detected to be more than setting (99°C
/1.0MPa (10bar)),water will be released through the P&T Valve to decrease pressure and
temperature.
P&T Valve and Inlet/Outlet Pipes must be installed according to the following instructions:
1. Please refer to the P&T Valve installation label indicated on the water heater, P&T Valve must
be installed on the accurate position according to the installation label.
2. When connecting the pipe of P&T Valve , the P&T Valve must be installed downward.
The outlet of the discharge pipe connecting the P&T Valve must be positioned approximately
100~150mm away from the ground, so that it is easily observable when hot water is being
drained to ensure user safety.
3. The diameter of piping should be 1/2” BSP. Connect the inlet pipe (blue) with water supply.
Then connect the outlet pipes (red) with supply pipe leading to points of use.
4. Turn on the hot water tap. Turn on water supply switch until the inner tank has been filled up
with water. The inner tank has been filled up when water flows from the water tap.
Power Switch
The external switch is used to completely disconnect water heater from power supply. It should
disconnect all poles, and a contactor separation of at least 3mm must be present.
Initial Operation
Rasonic’s water heater hybrid series is designed for operation on 220VAC, and must be installed
by authorizes technician with earthed outlet.
Fill the inner tank with water before conducting the following procedures:
• Ensure that the appliance is disconnected and that the fuse is deactivated.
• Turn on the hot water tap of the installed mixer to ll the appliance until
bubble-free water emerges from the outlet.
• Check the system for leaks and remedy these if necessary.
• Switch on the appliance.
• The inner tank water temperature will automatic setting and remain in
attendance while the water

安裝定位
熱水器應安裝於接近水龍頭的位置，以減少熱量流失和機身耗損率。如需掛牆安裝，請務必需要
使用爆炸螺絲（膨脹螺絲）並安裝在能負重的牆壁上，安裝的位置請儘量調整至緊貼牆壁。
安裝排放閥及水喉接駁
熱水器的溫度及壓力減卸閥（下稱 P&T Valve），當感應熱水器内的溫度/壓力超過設置時
（99℃ /1.0MPa (10bar)），便會自動從P&T Valve 排出熱水以減少壓力。
安裝後初次啟動
重要事項:
樂信牌電熱水器速熱系列設計用於市220伏電壓，電源接駁需由專業技工進行及必須緊接地線。
地拖式插頭不得使用。
把熱水器內膽注滿水後，才能執行以下步驟：
• 檢查電源或雙極總掣在脫開狀態。
• 打開混合閥熱出水口，放水至完全沒有氣泡排出為止。
• 檢查所有水管介面有否漏水，必要時修補後從覆上述步驟。
• 啟動電源。
• 顯示屏亮起，本熱水器開始自動調節適合溫度及留意熱水器加熱情況有異常。
少量水會 P&T Valve 閥口滴出及加熱滾動聲，均屬正常的現象。
開關
設於熱水器外用以切斷電源供應之開關掣，應全極切斷電源，兩極之間應保持最少3 厘米距離。
P&T Valve 及水喉必須依照以下指示請合資格技工進行：
1. 請參考熱水器爐身貼有的 P&T Valve 標示，取出 P&T Valve 並安裝於指定位置。
2. 連接膠水管時，P&T Valve 必須向下垂直安裝。P&T Valve 接駁的熱水排水喉必須離地約
100 ~ 150 厘米，以便容易察覺排水狀況，確保使用者安全。
3. 水喉管件直徑應為½”英制。將自來水喉接駁到入水喉(藍色)，再由出水喉(紅色)接駁水喉通往各
個出水龍頭。
4. 接駁妥當後，打開出水龍頭 (紅色熱水掣)， 然後打開水源總掣讓自來水注入熱水器內。
當水從龍頭流出，表示內膽滿溢，此時可關掉紅色熱水掣。
安裝時須注意
安裝全過程必須採用原廠配件，如違反指示將會失去保養效用。
如若因違反指示進行安裝或維修，從而引至任何損壞或傷亡，代理商一概不負責。
一切安裝及維修必須由合資格技工進行

Draining
To drain off water from the inner tank:
1st - Turn off both power and water supply. Let hot water inside the inner tank cool down if need.
2nd - Unscrew the drain plug to release water.
Source of Water Supply
Never connect Rasonic’ s water heater to other source of water supply, other than the potable
water supply as the result will have no warranty to the Company.
Water Shortage
During water shortage, do not drain water from inner tank. The heating element would be
damaged if it is not submerged under water. When water supply resumes, turn on hot water tap
and let water flows through the shower head before switching on the power.
內膽排水
如要將內膽內的水排走:
首先，必須先關掉電源及水源，等待剩餘之熱水冷卻 。
然後，旋開排水喉之喉蓋，讓水排出。
水質問題
切勿將熱水器連接到除飲用水供應以外的其他供水源，否則公司將不提供任何保用 。
停水期間
停水時不應將熱水器內之存水用盡，否則會導致發熱線損壞。恢復供水後，應先扭開熱水掣直至有
水從花灑流出。待內膽注滿水後，用戶才可重新開啟電源。
