WINTERIZING YOUR SPA

Cold climates, where danger of freezing exists, require special care on your part in order to prevent damage to the spa

shell and equipment. If you plan to use your spa during the cold months, be sure your pump is running frequently
enough to keep the water moving so that the heater will operate. It may be best to set your controls to keep the pump

on low speed at all times. This will keep the water from freezing and the heater will come on as the temperatures drop.

WARNING:

If you have a power outage, and cold temperatures are possible, your

spa and equipment could freeze, especially if it is mounted in a deck

without a cabinet. Ice in the spa and equipment will cause damage.

You should consider the need to have your spa professionally winterized if it is to be dormant

for a period. This is especially true if you are taking an extended winter vacation.

Follow the procedure below to help prevent damage to your

spa and related equipment:

Drain the spa of all water, as outlined in owner's manual. Shut off the spa's power supply.

Remove any remaining water with sponge. If you have a shop vac, try vacuuming as much water as possible

out of the jets and spa shell. If you cannot remove all of the water (especially from the air injectors) RV style or
plumbing system anti-freeze should be added to the injectors.

Remove spa equipment system and pump for storage inside. If this is not practical, use the shop vac again to
draw any water from the pump(s) casings. Remove lower casing drain plugs. Add anti-freeze to all pump

housings. (see note below)

When vacuuming spa lines:

Vacuum at all suctions in the foot well. This could be 2-6 suction depending on the model.

Vacuum at the heater input (union and gate valve), usually on the left of the equipment side of the spa.
Vacuum until you feel no more water coming out, then block the 2 cartridge mounts or block the Elite or
Teleweir opening
Remove the cartridge(s). Thread plugs into the threaded cartridge mounts in the filter box. For Elite or
Teleweir filter system, remove the Vane weir/trim ring and float assembly. Cover the filter opening with

rigid plastic and use something with weight to hold it down. Vacuum again at the heater input.
This will help draw water out of any lines connected to the spa pack, especially for spas that do not have a

circ pump.

The filter should be drained and cartridge removed and cleaned. Remove the filter cartridge and pour anti-

freeze as mentioned earlier into the filter canister. Store the filter element in a room with above freezing
temperatures.

Support the hard cover along the hinge with 2 by 4's across the spa. Lock your hard cover over the spa and
cover entire spa with a tarpaulin. Block the tarp in place or staple to your cabinetry.

When you refill in the spring, remember to re-install any plugs that were removed. Follow the directions for
start-up, as if this were a new spa.

Note: Any RV style or plumbing system anti-freeze used may leave behind a residue that could cause a white "fizz" in

the first refill of water, especially when the jet pump(s) are turned on. You may need to drain and refill the spa to clear
away the residue. During colder months of the year, plumbing anti-freeze is added to all pump housings as part of our

production procedures. This fact is noted on the outer spa packaging.
