Basic Operation and Maintenance

Basic Operation and

Maintenance (Homeowner)

Startup

1. Check system pressure and compare to pressure at

the time of shutdown. A significant loss of pressure

may indicate a leak in the system.

2. Check the system for signs of leakage.

3. Make sure all valves are in the open position.

4. Check to make sure the unit has power.

The display should be illuminated.

5. Set the thermostat to the desired level

(if it was turned down during the off-season

or the power was disconnected).

Shutdown

1. Check and record system pressure.

2. Turn thermostat down to 60°F (16°C),

or shutoff the breaker to the unit.

Exercise Pump

During the non-heating season, it is a best practice

to run the pump once a month for five minutes.

Refer to the following steps to activate the pump.

1. Turn on power to the Radiant Ready 30E.

2. Press the Tool

button for two seconds to

access the configuration field.

3. Press the Tool

button three times to select

the pump icon

4. After selecting the pump icon, press the +

button

to select ON to activate the pump.

5. After exercising the pump for five minutes, return

pump delay to original setting by pressing the

Tool

button for two seconds to access the

configurtion field. Then press the Tool

button three times to select the pump icon .

6. Use

buttons to select desired

setting. Then turn power off to the Radiant Ready 30E.

Glycol Maintenance

Check glycol systems at least once a year to ensure

the system pH levels have not dropped below

recommended levels. Glycol, in general, is acidic. The

inhibitors that are added to them help neutralize the

system pH and help protect the system components.

As the system ages, the inhibitors breakdown,

causing the system pH to drop. Consult the glycol

manufacturer for instructions on adding inhibitors

to the system. Note that the system will reach a

point where it will require a complete flush and

refill. Ensure an Uponor-trained installer performs

this maintenance.

Propylene glycol is the only type of glycol Uponor

recommends in a radiant system. When mixing

propylene glycol with water for a radiant system, there

should not be more than 50% glycol by volume, as

this may also cause damage to the radiant system.

DO NOT use methanol or ethylene glycol.

These fluids may damage the Radiant Ready

30E components.
