Dometic Tank Discharge Control Intended use
3.2 OPTION 2: DTD02 discharge control panel with DTM04 tank monitor system
When integrated with the Dometic DTM04 Tank Monitor System, the DTD02 Tank Discharge Control
panel will automatically shut off the discharge pump when the holding tank is empty .
Caution!
Operator must know local regulations for emptying a holding tank.
Note
The US Coast Guard allows a key-operated switch as a means to secure an overboard
discharge pump system. Turn off DTD02 system and remove key from switch when boating
in “No Discharge” waters.
3.3 Features
Secure discharge pump control. Key-operated switch provides convenient means to secure
discharge pump operation without use of padlocks or other mechanical fasteners .
Helps prevent pump burn-out. Activated panel light indicates when discharge pump is operating.
Reminds operator to shut off pump when tank discharge is complete .
Prevents potential damage from discharging tank against closed seacock. Activating a discharge
pump while seacock is closed can cause pressure build-up in discharge hose which may damage
pump or boat and result in costly repairs. The seacock interlock switch (available separately) greatly
reduces this possibility .
Automatic pump shut-off with DTM04 tank monitor system. Discharge pump stops when tank
level drops below “empty” level probe (fig.
6 C, page 4).
Simplifies plumbing system. Eliminates wye valves and vented loops of multi-toilet systems .
