Amtrol SOLAR EXTROL SE-15 Installation instructions

USE ONLY IN RESIDENTIAL CLOSED HYDRONIC
SYSTEMS. Do not install on domestic water
systems, or in open heating systems. Corrosion and tank failure may
result. Use a Therm-X-Trol®or Therm-X-Span®for domestic water
systems. Use a Solar EXTROL®for closed-loop solar heating systems.
READ CAREFULLY THE PRODUCT INSTALLATION,
OPERATING AND MAINTENANCE MANUAL.
FAILURE TO FOLLOW THE INSTRUCTIONS AND WARNINGS IN THE
MANUAL MAY RESULT IN SERIOUS OR FATAL INJURY AND/OR
PROPERTY DAMAGE, AND WILL VOID THE PRODUCT WARRANTY.
THIS PRODUCT MUST BE INSTALLED BY A QUALIFIED
PROFESSIONAL. FOLLOW ALL APPLICABLE LOCAL AND STATE
CODES AND REGULATIONS, IN THE ABSENCE OF SUCH CODES,
FOLLOW THE CURRENT EDITIONS OF THE NATIONAL PLUMBING
CODE AND NATIONAL ELECTRIC CODE, AS APPLICABLE.
This Product, like most Products under pressure,
may over time corrode, weaken and burst or
explode, causing serious or fatal injury, leaking or flooding and/or property
damage. To minimize risk, a licensed professional must install and
periodically inspect and service the Product. A drip pan connected to an
adequate drain must be installed if leaking or flooding could cause
property damage. Do not locate in an area where leaking could cause
property damage to the area adjacent to the appliance or to lower floors
of the structure.
CALIFORNIA PROPOSITION 65 WARNING! This product contains a
chemical known by the State of California to cause cancer and to cause
birth defects or other reproductive harm. (California Installer/Contractor
- California law requires that this notice be given to consumer/end user
of this product.) For more information: www.amtrol.com/prop65.html
RUPTURE OR EXPLOSION HAZARD. Do not
expose product to freezing temperatures or
temperatures in excess of 250° F (Intermittent); 225° F (Continuous).
Do not adjust the pre-charge or re-charge this Product except during
installation or regular inspection. Replace the Product and do not adjust
the pre-charge if corroded, damaged or with diminished integrity.
Adjustments to pre-charge must be done at ambient temperature only.
Failure to properly size the Product or follow these instructions may result
in excessive strain on the system and may lead to Product failure, serious
or fatal personal injury, leakage, and/or property damage.
A relief valve must be installed to prevent pressure
in excess of local code requirement or maximum
working pressure designated in the Product Manual, whichever is less. At
least once every 3 years or if discharge is present, a licensed contractor
should inspect the pressure relief valve and replace if corrosion is evident
or the valve does not function. FAILURE TO INSPECT THIS VALVE AS
DIRECTED COULD RESULT IN UNSAFE PRESSURE BUILD-UP
WHICH CAN RESULT IN PRODUCT FAILURE, SERIOUS INJURY OR
DEATH AND/OR SEVERE PROPERTY DAMAGE AND VOID THE
PRODUCT WARRANTY.
Chlorine & Aggressive Water: The water quality
can significantly influence the life of this Product.
You should test for corrosive elements, acidity, total solids and other
relevant contaminants, including chlorine and treat your water appropriately
to insure satisfactory performance and prevent premature failure.

SOLAR EXTROL®is designed for use in a closed-loop solar heating
systems with a maximum operating temperature of 250° F (Intermittent);
225° F (Continuous).
Pre-Installation
1. Visually inspect for any damage. Ensure expansion tank is sized
properly for the application (Figure 1).
2. With tank empty of fluid, remove plastic cap from air stem (Figure 2).
3. Adjust air precharge to match the system fill pressure. Unit is shipped
at 25 PSIG.
4. Replace cap and tighten snugly, ensuring the cap is flush against the
tank surface.
FAILURE TO PROPERLY SEAL VALVE CAP
WILL RESULT IN LOSS OF PRECHARGE
CAUSING PRODUCT TO FAIL.
Installation
1. Drain the solar system or isolate the area where the Solar Extrol will
be installed.
2. Install the Solar Extrol on the suction-side of the circulator (Figure 3).
Mount tank vertically only. Ensure the piping can
support the entire weight of the tank when full .
Do not install on a dead-end pipe or wherever air
can collect. This can cause internal corrosion
and possible leakage.
Do not install in floor joist space.
3. Once the Solar Extrol is installed, re-pressurize the system and check
for leaks. Repair as necessary.
4. Restart the system and check for relief valve discharge. If the relief
valve drips, the tank may be improperly charged or undersized.
5. The Solar Extrol is now operational and will absorb expanded fluid
during system operation.
Operation
1. The Solar Extrol is installed on the supply-side of the solar system. Its
sealed-in air pre-charge prevents fluid from entering the tank until the
system pressure begins to rise.
2. As the water temperature rises, fluid enters the Solar Extrol.
3. As the system cools, the diaphragm is forced downward. Fluid is
expelled from the Solar Extrol, back into the system.
NOTE:
Although the Solar Extrol does not have to be installed at the base of an
air purger, this installation is recommended to reduce air in the system
and provide a compact installation. Some method of air elimination is
required to reduce entrained air.
Maintenance
A professional plumber should check the complete system, including
the expansion tank, yearly and more frequently as the system ages.
Checking the precharge allows a small quantity of air to escape and can
result in an insufficient air charge. Always check the precharge while the
tank is isolated and empty of fluid, and be sure to maintain the proper
precharge whenever the tank is inspected. Monitor the tip of the service
indicator cap for discoloration (Figure 4) in addition to regular product
inspection. Contact the installer or a plumbing professional if indicator
cap is discolored; tank replacement required. Do not rely on cap as sole
indication of tank condition.
