water Care
There are three things necessary for clean safe water:
1. CIRCULATE: Water has to be circulated regularly; it can not be stagnant.
2. FILTER: Water has to be filtered to remove particulate and debris.
3. SANITIZE: Water has to be sanitized to kill organisms like algae, bacteria
and virus.
It is critical to maintain proper water balance to protect the vessel heater and
other components from damage. Damage to the vessel surface and equip-
ment caused by poor chemical or harsh chemical treatment is not covered
under the warranty. Discoloration of jet faces, valves and controls are an indi-
cation of poor chemical maintenance or exposure to the sun.
Jet inserts and valves do not qualify for labor coverage. These parts can be
purchased or exchanged under warranty at your authorized Marquis® dealer.
Gaskets and seals are not covered under the warranty.
The control system in your Marquis vessel will automatically circulate and filter.
(See Vessel Control Operation, ConstantClean™ and SmartClean™ sections.)
The sanitation requires minimal effort if done consistently and properly.
To sanitize vessel water, three things are required:
1. BALANCE: The water must be balanced so the sanitizer can work and
vessel equipment is protected.
2. SHOCK: Shock to oxidize organics and maximize sanitizer efficiency.
3. SANITIZE: Maintain a proper level of sanitizer at all times.
underStandInG water BalanCe
Water balance is the interrelation of factors that determine the quality of the
vessel water. The effectiveness of chemicals and other additives are de-
pendent on all these factors working together or "in balance". The primary
elements to water balance are the calcium hardness, total alkalinity and pH.
Always use water treatment products recommended for use in a Marquis
vessel.
phBalance
Keeping the pH balanced is the most critical component of water balance.
Calcium hardness and total alkalinity act as buffers to stabilize the pH. When
they are properly adjusted, the pH will be stable and easy to maintain. The
pH is a measure of the relative acidity and basicity of the water. The ideal pH
range is 7.4 - 7.6. When the pH falls below 7.2, the water can become cor-
rosive. Low pH can cause damage to metal in the control system and heater,
excessive sanitizer consumption, and skin irritation. A pH above 7.8 can be
scale-forming and allow metals or minerals in the water to form deposits and
stain vessel surfaces. pH above 7.8 can also cause eye and skin irritation.
