valve at the low point and drain water as required until the piping error can be
corrected.
3. If the above cheek out, detergent foam may be blocking the Treatment Tanks vent
(this is possible but unlikely, since the vent and traps are sized for this worst case).
4. If the back pressure persists, wash down the Treatment Tank vent from its upper
termination with a stream of high pressure water to clear any possible blockage.
Before doing this, set discharge Pump(s) to ON and watch Disinfecting tank sight
glass to prevent flooding.
5. If the Treatment Tanks vent is not the correct size, back pressure will almost certainly
occur every time a highsuds detergent is introduced into the system..
9.8 HIGH WATER LEVEL IN TREATMENT TANK
Obvious, check all valve positions, also in external piping to the overboard connection,
if this is found in order.
There can be several causes; The spillover hose (inside treatment tanks, to disinfectin
tank) are clogged, the vent on the disinfecting tank is blocked, or the Treatment Tanks are
overdue pumpout.
1. To clean the spillover, open inspection hatch on top of the Treatment Tanks and wash
out the vent with a stream of water. It is preferred to flush- and pump out the contact
tank after this action.
2. To clean the spillover inside the Treatment Tanks by flushing with water.
9.9 WATER SPILLING OUT OF THE CONTACT TANK VENT
This almost certainly is caused by failure of the Discharge pump, its controls, or by
discharge valves being closed.
1. Check valve positions, also in connecting pipe to overboard discharge.
2. Make sure the pump switch is set to Auto and that power is present.
3. Make sure the suction valve from the Disinfection Tank „V3“ is open
4. Check out the starter, motor, (especially thermal protection switch) and pump.
Controls should be set per "Set-Up for Operation" of this manual. Check function by
manual start of pump, if this does not work, check level switch for proper function, if
needed, clean out or replace.
