Installation：
It is highly recommended to install filters to protect potable water installations against corrosion. When used at the domestic point of entry, the Duo DFR filter should be installed directly behind the water metering device and be readily accessible.Thoroughly flush the pipe prior to installation. Use filtered water from the first onset of the potable water installation. The main axis of the filter has to be in vertical position. Install the filter under consideration of the direction of flow (arrow on the body) in the pipework without applying stresses.
安裝：
積極建議您採用這款自來水專用SYR德國DuoDFR手工反洗過濾減壓閥對抗水管鏽蝕，當安裝於家用自來水進水幹管時，請直接裝設於水表後方掬手可得的地方。安裝前請使用濾過的水徹底沖洗進水幹管，安裝時請注意in/out水流方向，過濾器主軸需保持垂直。

Maintenance：
A maintenance indicator positioned on top of the filter indicates when service is due. The filter should be backwashed every two months at the latest. Servicing the Duo DFR requires no special tools. To service the filter, open the ball valve and turn the lower part of the filter 2 to 3 times to the left or to right. Close the ball valve again. Even during backwashing, the device continues to supply filtered water into the potable water system.
保養：
這款SYR德國手工反洗過濾減壓閥頂部有調整指針可明示上次保養時間。最晚每兩個月要手工反洗一次。操作時不需要特殊工具，直接打開球閥，然後將過濾器下半部左右轉動兩至三次，最後關上球閥。反洗操作期間，自來水仍能照常供應。
