Manual Add Valve/Metering Orifice
The manual add valve is for adding oxygen to the loop. The O‐rings should be changed annually or if the flow rate
changes, more the orifice. All components in the add valve must be clean, oil free, with the O‐rings lightly lubricate
frequently. The inlet of the valve is protected by a 15 micron filter. This filter will NOT stop seawater from contami‐
na ng the orifice. All components in the add valve must be clean, oil free, with the O‐rings lightly lubricated with oxy‐
gen compa ble grease.
The tools required to disassemble the valve are a wrench or Allen key, small snap ring pliers and a jewellers screwdriv‐
er. First, insert the snap ring pliers into the snap ring on the bu on end of the valve and remove.
Remove the nut with either the wrench or Alan key, depending on which nut you have; pull out the spring. The spool
and orifice are all that is le inside the valve.
DO NOT SCRAPE OR GOUGE THE BORE!!!!!!
To remove the spool and orifice push in the bu on using a jewellers screwdriver. This will force the spool and orifice
out the other end. When you have the spool removed, cut the old O‐rings away with a sharp knife and replace them
with new V75‐008 O‐rings which have been lubricated with an oxygen compa ble lubricant such as Christolube. Do
not scratch the O‐ring grooves. The orifice does not need to be removed unless it is damaged or plugged.
