 清潔熱水器外殼及喉管祗須用軟布輕抹即可,不得用清潔液擦洗。

 熱水器整體、接電及接水部件需每兩年由專業技術人員進行檢查,確保熱水器的安全運作。

 溫度及壓力減卸閥應定期運行,以清除石灰沉積物並確保沒有阻塞。

 溫度及壓力減卸閥亦需每月自行檢查一次,確保操作正常。

- 把小手柄拉出直至水閥打開及水從閥口流出,然後放回手柄關閉便可。
- 如繼續有水滴出,請專業技工進行檢修。

 建議用戶每年清洗熱水器內膽一次:

- 關閉所有水掣及電源。
- 拆卸放水塞,把水引放到排水口,開啟水掣清洗,清洗後重裝水塞,然後重覆初次啟動步驟。

• Heater surfaces and fittings may only be wiped with a damp cloth. 

  Never use abrasive cleaning agents or solvents.
• The electrical and plumbing components should be inspected by an authorized technician 

  every two years to ensure proper functioning and operational safety at all times.
• The P&T Valve is to be operated regularly to remove lime deposits and to ensure there is 

  no blockage;
• The P&T Valve must be vented slightly at regular intervals (once per month) to ensure

  proper functioning

- Pull the lever until the valve opens and water drains from the outlet. Re-close the valve.

- If water continues to drip from the P&T Valve, call authorized technician to examine the 

  P&T Valve.

• Cleaning the inner tank once a year is recommended: 

- close all valves and disconnect the power supply, 

- dismantle the drainage plug and drain off water to the drainage, slightly open the stop valve

  to clean the inner tank, tighten the plug after cleansing and repeat the ‘Initial Operation’ 

  procedures.
