You will find here some winter prep info for the different models of heat exchanger on the market. If you don't find your pool heater manufacturer in the list, look at the exchanger in your machine to find out the appropriate technique to dry out your pool heater before winter.

Ground rules: (Applicable to all models)

1. First, turn the breaker to off

2. Always disconnect all pipes from the pool heater and remove drain plug if applicable.

3. When gravity can't assure complete drainage, use the air outlet from a vacuum cleaner or any air blower to push out any residual water in the exchanger.

4. Blow the air in both the inlet and outlet of pool heater for many seconds.

5. Ensure the exchanger is completely empty. (Find your heat pump model in the following notes if required)

6. Plug the in and out access to the exchanger to eliminate the risk of water returning inside the exchanger after the pool is closed.

7. Place a cover over the pool heat pump.

Specific rules  per model.

• Summit Titanium 2002 to early 2005.

(Vertical exchanger with drain)
• Disconnect both water connections and remove the drain plug on the pool heat pump.
• Leave drain and pipes removed until complete drainage
• Empty both pipes to the filter
• Unscrew the drain plug. Wait until exchanger is completely empty
• Reconnect pipes. If you store the hoses, plug the exchanger openings with rags and cover the ends with plastic bags

Summit models without drains. (Tube in tube / Streamer)

Also applicable for most of these products: Aerotemp, Tempo, Tempro, Olympic, Turcotte, Maxtemp before 1989, Ultra before 1994, Thermo-Max, Smartemp, Calorex and most of the imported products.



• Disconnect both water connections on the heat pump
• Blow air into the water outlet to drain all residual water.
• Empty both pipes to the filter
• Blow air in the water inlet for a few minutes
• If no blower is available you can slightly lift the front of the unit (20 cm maximum), 8 to 10 times. Make a pause between every movement to permit the water displacement in the exchanger
• Reconnect pipes. If you store the hoses, plug the exchanger openings with rags and cover the ends with plastic bags

Example of tube in tube or streamer exchanger.



 

• Other products with Horizontal canister exchanger (Mostly on  Maxtemp  after 1989 and all Focustemp products)

• Disconnect both water connections on the heat pump
• Empty both pipes to the filter 

• Attention ! These canister exchanger have the in and out in the center of the canister. (See picture)  So the gravity and air blowing will inevitably leave a few centimeters of water in the bottom of the canister. 

• The best technique is to tilt the machine at  45°. Keep the position until the complete draining of the exchanger.

• If your installation prevents tilting of the unit, a wet/dry vacuum cleaner connected to a small tube to the bottom of the exchanger can be used

• Another alternative is to use plumbing biodegradable antifreeze liquid and fill the bottom of the exchanger. This liquid is heavier than water and will push the water out. Fill until you see the antifreeze liquid coming out of the exchanger.

• Reconnect pipes. If you store the hoses, plug the exchanger openings with rags and cover the ends with plastic bags

• PVC Valves
  • For the winter, when the PVC valves stay in cold area, a good way to reduce the risks of breakage, is to place all handles at 45° and to loosen the Unions . (see Picture)
