Filter Cartridges - Marquis Vector21 Owner's Manual

Shut-off valve in
open position
SHUT-OFF VALVES
Your spa is equipped with shut-off valves (see EQUIP-
MENT DIAGRAM) that shut off the water flow to the
equipment system for authorized Marquis
service. At times, a new spa or one that has recently
been serviced, may have the shut-off valves partially
closed which can restrict the water flow and hinder jet
performance. Be sure the valves are fully open.
FREEZE PROTECTION
When a freeze condition is detected (which occurs
when the temperature in the heater housing drops to
55°F, (13°C) the jet pump(s) is automatically activated.
In areas with extremely cold winter conditions, your
spa should be fine as long as it is left running at normal
operating temperatures. For extra protection see your
dealer for an optional freeze sensor. If you plan to turn
the spa off, follow the instructions in this manual (see
SUSPENDED USE OR WINTERIZING YOUR SPA).
OVERHEATING
In the case of extended hot weather, the spa water
temperature may reach and maintain 104°F to 106°F
(40°C to 41°C) or higher. This is due to the ambient
temperature and the full insulation in the spa cabinet.
You have the option of changing when or how long
the pumps will run. See SPA CONTROL OPERATION
for available options.

FILTER CARTRIDGES

Your portable spa is equipped with the Constant-
Clean™ Filtration system. It features two Vortex filters.
NOTE: It is very important that the components of
these filtration systems be installed properly in the
proper part of the spa.
1. Hold the Vortex filter cartridge and center it in
the opening of the filter housing.
2. Use the filter handle and turn the filter cartridge
clockwise to screw it in place. (Use caution not
to overtighten as damage may occur to
threads and is not covered under warranty.)
3. Replace the filter cover.
