FILTERS

• Turn off the pump and circuit breakers. • Open air release valve on top of the filter. • Remove the drain plug at the base of the filter to ensure that the tank empties. • Store the drain plug and o-ring in a safe place(Do not reinstall until next season at start-up). • Drain system piping of all water.

If the filter has a backwash valve, backwashing the filter should be done first before draining. If a multiport backwash valve has a "Winterize" position, move selector lever to that position which leaves all ports partially open for the winter non-operation, and on some backwash valves also moves the seal to a relaxed position.

PUMPS

To protect your pump, Zodiac Pool Systems, Inc. recommends having a qualified service technician or electrician properly disconnect the electrical wiring at the switch or junction box. Once the power is removed, the two (2) unions can be loosened and the pump stored indoors. For safety, and to prevent entry of contaminants, reinstall all conduit and terminal box covers.

• Drain all water from the pump, system equipment, and piping. • Remove the two (2) drain plugs. • Store the drain plugs in a safe location and be sure not to lose the o-rings. • Keep the motor covered and dry. Do not cover it with plastic, as this will create condensation and this moisture will damage the pump. • When the system is reopened for operation, make sure all piping, valves, wiring, and equipment are in accordance with the manufacturer’s recommendations. Pay close attention to the filter and electrical connections. • The pump must be primed prior to starting; refer to your owners manual “Start up procedures” for your spring start-up and further instructions.

HEATERS

To prevent excess condensate in the combustion chamber it is recommended that the water temperature be maintained at 70 degrees or higher. The heater should not be used when water temperatures below 41 degrees or if the ambient air temperature around the heater is below 21 degrees.

• Turn off the electrical supply and the main gas supply to the heater. • Remove the heater access panel. • Turn off gas valve inside the heater. • Remove the drain plug from the inlet/outlet header and completely drain the heater before the first frost. • After all water has drained from the heater, check for mineral buildup in the openings. • Inspect the gasket on the drain plug. Store the drain plug in a safe place for winter. • Cover the vent grill with plastic so that snow will not accumulate and freeze in the combustion chamber. • Remove and drain the pressure switch tubing.

HEAT PUMPS

Cover only the top of the heat pump to prevent debris from falling into the unit. Do not wrap the sides of the heat pump with any plastic or other material that will retain heat or moisture inside the unit.

• Turn off the electrical power to the heat pump at the main breaker panel. • Shut off the water supply to the heat pump. • Disconnect the water inlet and outlet unions as well as the winterizing drain plug (if applicable) located on the lower front panel of the heat pump. The heat exchanger will drain through these water connections.

SALT SYSTEMS

Very little chlorine is needed in cold water. Below threshold temperatures chlorine production is not permitted; operating the chlorinator in cold water might result in over-chlorinated pool water. If preventative measures are not taken, freezing water may cause severe damage to the cell and flow/temp/salinity sensor. Prevent freeze damage to the cell and flow/temp/salinity sensor by running pump continuously or winterize pool by draining water from pump, filter, and all intake and return lines.

• DISCONNECT POWER SOURCE • ADJUST ALL NECESSARY VALVES • OPEN FILTER AIR RELIEF • REMOVE/CLEAN AND STORE CELL • INSTALL WINTERIZING KIT PER INSTALL MANUAL

LIGHTS

As a general rule, large pool lights are unattached from the wall, weighted and lowered to below the water line to prevent being exposed to the air. While smaller LED lights are generally left loose in the wall fitting or completely

removed from the pool.

• The water level should be lowered to approximately 12 inches below the pool lights. • Make certain that the water is drained out of the wall housing. • Minimum safeguard requires dropping the water level 2”-4” below the light.

Requires 2" - 4“ below light

Recommended 12" below light

WINTERIZATION WATER LEVEL

OZONE

• Disconnect the power to the ozone generator. • After the generator has been shut down, the pool water circulation pump may be turned off. • Disconnect the ozone tubing and tube adapter from the unit and store indoors. Install the 3/4” pipe cap provided on to the injector to seal the system. • Blow the plumbing lines clear as normal winterizing procedures call for.

QT BLOWER

• Drain the water from the spa to at least 2 to 4 inches below the air lines. • Turn the blower on until water no longer comes out of the lines. • Turn the power off at the blower. • If possible turn off power source.

If the air hole returns are in a vertical direction or angled where water may accumulate, preventative action should be done to prevent possible freezing in the pipes.

OTHER CONSIDERATIONS

When considering winterization, many factors can alter the type of pool closure that is necessary. It is important to understand what priority to place on the individual factors. Such factors include: type of pool finish, tiles or no

tiles, type and depth of lights, using a winterizing cover and what type of cover, even the demographic can greatly change the type of procedures you

can use for a long term pool closure. Please follow all the manufactures procedures and consult an industry professional whenever needed.

Prior to draining the pool, check with your local authority having jurisdiction regarding water disposal rules and check with the National Water Information System at http://waterdata.usgs.gov or create a Flood Insurance Rate Map through FEMA at

https://msc.fema.gov/portal/search regarding the water tables in your area.
