The Lectra/San EC Type I MSD can be connected to
two marine toilets. However, the two toilets must be
in close proximity to:
1. Reduce the pressure requirement to move waste
through the connecting hose.
2. To decrease the possibility of untreated sewage
remaining in the lines.
The Lectra/San EC Treatment Tank should be lo-
cated midway between the two toilets. The maxi-
mum distance from either toilet to the tank should
not exceed six feet.
A kit is available for field conversion to dual toilet
operation:
Lectra/San EC Dual Control Component part
#LSTEDC (for 12 V units):
1. Control Indicator Panel with ribbon cable at-
tached.
2. Salt Feed Tank complete.
INSTALLATION
1. Adding second toilet - Install Lectra/San and
first toilet per manual, then add second toilet by
connecting discharge line to the opposite side of
the tank. Remove the plug to allow connections.
(See Figures #11A and #11B)
2. Electric toilet - Installations with two electric
toilets must be wired to work independent from
the Control Indicator Panels. Contact Raritan
Customer Service for instructions.
3. Mounting - Each toilet should be installed within
six feet of Lectra/San EC.
4. Control Indicator Panel - The Dual Control
Indicator Panel attaches directly to the Lectra/
San EC circuit board, the original Control Indica-
tor Panel connects inline using the special con-
nector attached to the dual control ribbon (See
Fig. #12A).
OPERATION
Indicator/LED lights will indicate operation on both
panels when any toilet is in use. DO NOT activate
"Push to Flush" button if another toilet is in use.
A Salt Feed Tank should be installed in each toilet's
intake hose if operating in fresh or brackish water.
The flow control for each Salt Feed Tank must be set
independently.
