Jayco Embark 2023 Winterizing with antifreeze User Manual
Winterizing with antifreeze
- Close all the faucets in the coach (including the outside shower). Attach the shower hose to the outside shower quick connector.
- Close the fresh water tank drain and all other low-point drains. Include the hot/cold water line drain valves at the utility center (Fig. 2).
- The City Water valve should be set to the vertical (city water) position (Fig. 1).
- Water heater bypass valves should be set to the BYPASS position. Middle valve is ON and the two supply valves to the water heater OFF
- Place the clear hose from the utility center (Fig. 2) into a container of RV antifreeze (requires about 2 gallons). The clear hose is located at the utility center. The dashed circle in (Fig 1) indicates an item behind the utility center panel.
- The Siphon valve should be turned so it is in line with the clear plastic hose.
- Turn the water pump ON (Fig. 1) and antifreeze will be drawn out of the container and into the water lines as each fixture is opened in the motor home. To aid siphoning, place the antifreeze container on a flat surface approximately 2 feet off the ground.
Winterizing the Macerator System (if so equipped)
- Make sure all tanks are empty.
- Pour RV antifreeze into the toilet and down into the black water tank. At the time of printing, the quantity of antifreeze to be put into the black tanks was not determined. Check with Customer Service for proper amount to use.
- NOTE: Use a container (bucket) for capturing system fluid!
- Turn the macerator pump ON.
- Run the pump until antifreeze begins to discharge from the dump connector attached to the flex hose.
- Turn the macerator pump OFF.
- Drain the flex hose by holding it at a sloped angle to drain excess water and return the hose to the storage location.
- As an added safety measure, open and drain the Macerator Bypass Valve. Completing the Winterizing with antifreeze
- After all of the water lines/appliances have been winterized, turn the pump OFF and disconnect the shower hose from the outside shower.
- Turn the siphon valve so it points away from the clear hose (Fig 2). The valve is located behind the large panel on the utility center.
- Open the drain valve on the freshwater tank and leave it open.
- Add a cup of antifreeze in all the drain p-traps.
- Remove the clear hose from the container of RV antifreeze and clean.
- NOTE: To reduce the chance of contamination, prevent the clear hose from coming into contact with the ground or the water fittings.
- Wipe the antifreeze out of the sinks, shower, and toilet using a soft, dry cloth.
To De-Winterize the Fresh Water System
Close the fresh water drain valve. Fill the fresh water tank with fresh water and rinse the RV antifreeze from each faucet or appliance that was protected with the RV antifreeze.
Fill the fresh water tank using one of the following methods:
Method 1: Connect a pressurized water source to the City Water inlet. The city water valve (Fig 1) should be turned to the Tank Fill position (horizontal). Turn water source ON and fill the tank.
Method 2: Open the water tank compartment on the DOOR SIDE of the RV. Remove the fill cap from the water tank. Insert a hose (connected to a freshwater source) into the water tank. If there is a drain valve for the tank, it should be turned OFF. Turn the water source ON and fill the tank.
Turn off and disconnect the water source. Turn the pump ON. Turn the Water Pump Back-flow valve ON. Purge all antifreeze out of the water lines by opening all faucets (including outside shower). Once all the antifreeze is out of the water lines, turn the pump OFF, replace the canister water filter, and sanitize the system as necessary. De-Winterize the Macerator Toilet: Press either button to flush and return to normal condition. De-Winterize the Macerator System: Emptying the black tanks for the first time in the spring, will discharge antifreeze in the macerator pipe and flex hose.
Water Heater – Tankless
Your RV is equipped with a tank less water heater. The tankless water heater uses less LP gas than storage tank model water heaters since it only uses energy when hot water is demanded. There is no pilot light to burn when no hot water is needed. The tankless water heater sup-plies an unlimited supply of hot water on demand (once lines are purged of standing water). As hot water is used, the cold water enters the heater. A water flow sensor detects the flow-ing water and automatically ignites the burner. Water circulates through the heat exchanger and is heated to the set temperature. When the tap is closed, the unit shuts down. The tankless water heater does not require an anode rod to prevent corrosion, or a by-pass valve for winterizing. It is not affected by high altitudes.
The output temperature of the water depends on the temperature of the inlet water AND the amount of hot water that is drawn. If the inlet water temperature is over 65 º F, the tankless water heater will generate water in the range of 105°F to 120°F (on low flame) depending on the water flow selected by the user.
The tankless water heater can be operated in two different ways.
- Operate like a Tank Water Heater. Turn on the hot water and add cold water to achieve the desired Hot water temperature.
- Select the desired temperature by adjusting the temperature setting up (^) or down (v). The UCP settings are from 95° (F) to 124° (F). The unit will maintain the set temperature. The recommended and Factory setting is 115° (F) or 46° (C).
For normal operation:
- Turn on the power. The panel will light and display the current temperature at the inlet of the unit.
- Press a temperature selection arrow (up or down) to see the current set temperature.
- Adjust the set temperature to your preference.
- Turn on a faucet.
It is dangerous to operate a Tankless Water Heater unattended. This may occur accidentally if a sufficient leak develops in the water system or if a faucet is left open. The tankless water heater will automatically turn off after operating for 20 minutes and displays Error “en” on the Display.
Freezing of the water heater and its plumbing components will result in severe damage not covered by warranty Follow the recommendation(s) below if the unit is to be stored in a freezing environment for a long period of time. At the start of the winter season or before traveling to a location where freezing conditions are likely, the unit must be winterized. The very small amount of water present in the heat exchanger DOES NOT require the installation of a bypass kit. Refer to the Winterization section for details..
