This Liquidmate® soap dispenser has a translucent, shatter-resistant polyethylene container of 700ml capacity. Users should push valve up to receive 1.75ml of liquid soap. To refill the reservoir, one must unscrew the collar under the mounting bracket, turn the bottle and remove the valve. Any free-flowing commercially marketed hand soap is valid for this dispenser. No more than 22.2N of force are required to one-hand operate the valve, so this washroom fitting can be installed in accessible areas. The materials of the soap dispenser are corrosion resistant. Please, read the documentation below to perform the most suitable maintenance (avoid abrasive solutions).
