After all the air has been purged from the system and
a steady flow of water is coming from the shower
release the shower's trigger. Turn the FRESH WA-
TER" switch to "OFF" (which deactivates the pump)
when no longer needed.
NOTICE
If the line is routed improperly, kinked or is
dislo cated, the water pump may not operate
properly. Inspect and correct the hose routing
(if neces sary). If a prob lem still exists, con tact
your Scarab dealer for assis tance.
NOTICE
DO NOT operate the pump with an empty tank.
Damage to the water pump may result. Be sure
the pump switch is off when not in use.
To operate the shower:
Place the "FRESH WATER" switch "ON", push the
spray nozzle trigger to purge any air that may be in
the system. When a steady flow of water is coming
from the shower nozzle the air has been purged.
Release the spray nozzle trigger when finished. As
the pressure builds, the pump will automatically shut
off at 35 psi.
When properly primed and activated, the pressurized
water system can be used in the same manner as the
water system in a home. An automatic pressure
sensor in the water pump keeps the system pressur-
ized. Sim ply operate the spray nozzle and water will
be delivered. If the system has been recently filled, or
has not been used for an extended period of time, air
bubbles may accumulate at the pump. If this should
happen, re-priming may be necessary. Turn the
"Fresh Water" switch to "OFF" when not in use.
C. Disinfecting the Fresh Water System
The fresh (potable) water system should be
disinfected prior to initial use.
The water system should be disinfected before first
use and at the beginning of each season. The follow-
ing information is a general guide to disin fecting the
fresh water system.
Boat Systems - Section B
A suggested method of disinfection is taken the
American Boat & Yacht Council (ABYC H-23). Per-
form the following steps in the order indicated:
1. Flush entire system thoroughly by allowing potable
water to flow through it;
2. Drain system completely;
3. Fill entire system with a chlorine solution having a
strength of at least 100 parts per million, and allow
to stand for one (1) hour. Shorter periods will
require greater concentrations of chlorine solution.
See Table I.
4. Drain chlorine solution from entire system.
5. Flush entire system thoroughly with potable water;
6. Fill system with potable water.
Table I shows how much disinfecting agent is required
to make up various quantities of 100 parts per million
chlorine solution.

NOTE: This table contains information taken from the
Handbook on Sanitation of Vessel Water Points,
Public Health Service Publication No. 274 - Reprinted
June 1963.
To remove excessive chlorine taste or odor which
might remain in the system, prepare a solution of one
quart vinegar to five gallons water and allow this
solution to agitate in the tank for several days during
boating. Then drain tank and refill with fresh water.
Note: Sinks (if applicable) are equipped with traps,
and the water will drain slowly. If the system is not
operat ing properly, have it checked by your authorized
Scarab dealer.
