About your Haygain® HG-600 hay steamer

Congratulations on purchasing your Haygain® HG-600 hay steamer!
Mold growth can affect all types of hay and haylage. Molds produce respirable dust that when inhaled can cause respiratory allergies. These conditions compromise the ability of your horse to breathe properly. Mold growth also reduces the nutritional quality of the forage. Your Haygain® hay steamer is the only system scientifically proven to kill mold spores and bacteria in forage and remove the potentially allergenic respirable dust. Steamed hay helps to protect your horse from harmful dust and microorganisms, which allows your horse to perform to the best of its ability. Your horse will also love the improved taste of steamed forage.
Here at Haygain®, we are committed to improving the health and well-being of your horse. To see other ways that we can help you and your horse, visit www.haygain.com

Using your Haygain® hay steamer

Read the safety chapter
Before you use your Haygain® hay steamer, read the Safety chapter in this user manual.

After you set up your Haygain® hay steamer and make sure it is safe, you can start steaming forage. You can feed steamed forage to your horse immediately or ideally up to 24 hours after steaming.
To steam forage, complete the following tasks in this chapter:

1. Fill the steam generator with water.
2. Load forage in the hay chest.
3. Steam forage in the hay chest.
4. Unload forage from the hay chest.

If you are working in freezing conditions, see page 13.

Tip: If you fill the steam generator with 8 litres of water, you can steam two batches of forage consecutively. As the water in the steam generator is already hot after steaming the first batch, it is quicker to steam the second batch.
Filling the steam generator with water
Before you can start steaming forage, you need to fill the steam generator with water.

To fill the steam generator with water

1. Warning: Do not open the safety cap on the steam generator when the steam generator is hot. Ensure the steam generator has cooled down.
   Unscrew the safety cap on the steam generator.

2. To ensure the steam generator is empty, hold it by the handle and tilt it. Empty the water through the filler spout into a drain or container.

3. Place the funnel in the filler spout. To improve the flow of water into the steam generator, position the funnel so that the longer side of its stem is at the bottom.

4. Carefully pour up to 8 litres of clean tap water into the steam generator. If you are only steaming one bale, we recommend you use 6 litres of clean tap water.
   Warning: Take care not to overfill the steam generator with water. Never add antifreeze or other additives to the water.

5. Remove the funnel from the steam generator, then screw on the safety cap and tighten it by hand.

Loading forage
The hay chest can hold just over half a bale of forage, several hay nets, or loose forage. When steaming part of a bale of forage, re-tie it using bailing twine to keep it together. After steaming, cut and remove any bailing twine.
After steaming, any metal parts on hay nets will be very hot. The hot temperatures in the hay chest can also cause some hay nets to shrink. We recommend you use Haygain®
hay nets, which do not have any metal parts and are heat-resistant so will not shrink. You can order Haygain® hay nets from www.haygain.com

To load forage

1. Lift the lid of the hay chest.

2. Check there is no loose forage in the hay chest, and that the steam holes and drain holes are not blocked. If there is any loose forage or blockages, clean the hay chest
   before you load the new forage. Read more about cleaning the hay chest on page

4. Place the forage into the hay chest. Place hay nets or wedges of loose forage vertically, so that they are parallel with the sides of the chest.

5. Press the forage down firmly, being careful of the manifold spikes. Ensure the manifold spikes fully pierce the forage.

6. Close the lid of the hay chest and fasten the latches.

Steaming forage
When you steam the forage in the hay chest, the internal temperature of the hay chest can reach 80 °C and above. This represents a temperature of 100 °C in the forage. The A combination of hot temperature and moisture kills the mould spores and bacteria in the forage, protecting your horse from harmful dust and microorganisms.
If steam comes out of the filler cap when you are steaming forage, the pressure inside the steam generator is too high. This can be due to a blockage in the hay chest, steam generator or steam hose. For more information, see page 20.

Do not allow the steam generator to run out of water
If the steam generator runs out of water, also known as “boils dry”, it can be damaged. If the steam generator boils dry, a buzzer sounds and the empty indicator light turns red. Switch off the steam generator immediately.
Before you unscrew the safety cap and add more water, allow it to cool down. Do not stand over the steam generator when you unscrew the safety cap.

To steam forage

1. Warning: Before you plug the steam generator into a power outlet, mop up any water spillages around your Haygain® hay steamer. Ensure the plug, cable, and power outlet
   are clean and dry.
   Plug the steam generator into a power outlet.

2. To switch on the steam generator, press the power button. The power button turns green and the heating indicator light turns amber.

3. Steam the forage for 60 minutes, then check the thermometer on the hay chest lid.
   • If the temperature shown is at least 80 °C, steaming is complete.
   • If the temperature shown is below 80 °C, continue steaming until it is 80 °C.

4. If you want to load the second batch of forage and steam it, do the following:
   a. To switch off the steam generator, press the power button.
   b. Read about safely unloading forage on page 13. Lift the lid of the hay chest and unload the forage.
   c. Load the second batch of forage into the hay chest then close the lid and fasten the latches.
   d. To switch on the steam generator again, press the power button.
   e. As the water in the steam generator is already hot, steam the forage for 35 minutes. Then check the thermometer on the hay chest lid.
   o If the temperature shown is at least 80 °C, steaming is complete.
   o If the temperature shown is below 80 °C, continue steaming until it is 80 °C.

5. To switch off the steam generator, press the power button.

6. Unplug the steam generator from the power outlet.

7. When the steam generator has cooled down, unscrew the safety cap on the steam generator.

8. Hold the steam generator by the handle and tilt it. Empty the water through the filler spout into a drain or container, to reduce the build-up of limescale.

Unloading forage
After you steam forage, the forage is warm and smells sweet. Most horses love the taste and prefer it to dry or soaked hay. We recommend you make any changes to your horse’s diet slowly, to give their digestive system time to adapt. When you first start using steamed forage, mix it with your horse’s existing forage for a few days.
You can feed steamed forage to your horse immediately or ideally up to 24 hours after steaming. The steamed forage is slightly wet on the outside due to condensation on the bottom of the hay chest lid. However, the inside of the forage is dry to the touch.
To ensure the hay chest and its lid always fit together properly, keep the lid on the hay chest as they cool down.

Beware of hot steam when you open the hay chest lid
When you open the lid of the hay chest, stand to one side of the hay chest to allow steam to escape. Do not lean over the hay chest as steam escapes.

To unload forage

1. Lift the lid of the hay chest, opening it from the side to allow steam to escape.

2. Unload the forage from the hay chest.
   Warning: If the forage in the hay chest is too hot, wear protective gloves when you handle it. Take care when you unload hay nets, as any metal parts will be very hot.

3. Close the lid of the hay chest.

Working in freezing conditions
When the ambient temperature is very low, water can freeze in the hay chest, steam generator, or steam hose.

Do not use anti-freeze products
Do not use anti-freeze or other additives in the steam generator. Additives in the steam generator can be a health hazard to your horse or can damage the steam generator. It will also void the warranty.

To steam hay in freezing conditions

1. Disconnect the steam hose from the hay chest.

2. To ensure there is no ice in the steam hose, fill the steam generator with water and then switch it on. Do not load forage in the hay chest.
   • If steam comes out of the safety cap and not out of the steam hose, switch off the steam generator. To remove ice in the steam hose, place it in warm water and gently squeeze it. Then switch on the steam generator again.
   Warning: Do not unscrew the safety cap.
   • If steam comes out of the steam hose, continue to step 4.

3. To ensure there is no ice in the hay chest, connect the steam hose to the hay chest. Do not load forage in the hay chest.
