Your heater pump kit contains hoses, oump, thumb screw and 2 clampsYour HUG Hydronics in floor heating system
1. Connect the blue hose to the heat source or heat exchanger. 

When in doubt, add a clamp for a secure connection.

A heat exchanger. When using a hot water source like a wood boiler, solar, or existing boiler loop, this heat exchanger can make the interface to the HUG Hydronics system quick and easy.

2. Connect the blue end of the blue hose with the white pipe to the return side of the warm water side of of the heat source.

3. Run the unconnected end of the blue ended hose into the top of the tank through the first open hole on the right side of the tank.

4. Stick the white pipe end of the other blue hose into a hole on the left side of the tank.

Push it into the tank until it will go no further. If needed, move the other hoses to the right a hole or two to make room for the heater hoses from the additional heat source(s).

the pipe end of the hose should be standing up behind the half wall at the back of the tank

5. Connect this blue hose in the tank to the pump.

Slide it all the way on to the pump’s hose attachment.

 6. Install the pump. 

The right side of inside the tank. The nose holes for pumps 8 & 9 are seen

Install, (or reinstall) pump 9 (& 8 if adding 2 additional heat sources) so the long nose tip go through the hole in the back side of the tank, just like pump 10.

If it doesn't want to sit well, pull on the blue hose it is attached to until it cooperates.

If you didn’t purchase your HUG Hydronics system with enough pumps, you may order another pump for each additional heat source you plan to add.

7. Slide the box on the pump cord into its groove below the control board. 

Just below the control board are the grooves for the box on the pump cord.

Slide the box in from the top until the bottom is securely in place and then use the thumb screw to screw it in place on it’s top right side.

 8. Plug the pump into the white pump plug on it’s section of the control board.

The holes between the pump cord boxes and the control board can be used to pull any excess wire through.

9. Open the control board  and locate the pump control sections for 8 & 9

pump sections 8 & 9 on the control board are circles in purple

Put a jumper on the pins labeled “heat source” for each additional heat source you’ll use. (#10 is already a heat source). 

Set your pump speed as desired. 

Put a jumper on all zones you want it to heat for.

10. Purge the Pump. 

 thr purge pins for pump 9 are circled in purple. Put a jumper on these purge pins to purge the pump.

If the HUG Hydronics System has been turned off, turn on it on by using the switch on the power supply. 

On the control board, put a jumper on the “purge” pin for the new pump. The air will move out and the water into the loop. 

It is done when the gurgling sound ends. 

Remove the jumper from the “purge” pin.

11.  Add water to the tank as needed to reach the “full” level, about 3 gallons per loop.

The water level guide is in the tank below the control board. Use this to judge the amount of water to add.

Close the tank and lock the lid into place.

Turn on your heat source when you are ready to use it.
