INSTALLATION & OPERATION INSTRUCTIONS.
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 LICENSED
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.
EXPLOSION OR RUPTURE HAZARD. THE TANK
MUST BE OPERATED SO THAT THE PRESSURE
DOES NOT EXCEED THE MAXIMUM WORKING PRESSURE.
Use only lead-free solder and flux for all sweat-solder
connections, as required by state and federal codes.
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 leakage of the tank or
connections could cause property damage to the area adjacent to the
appliance or to lower floors of the structure.
This product can expose you to chemicals including
lead, which is known to the State of California to
cause cancer and birth defects or other reproductive harm. For more
information go to www.P65Warnings.ca.gov.
NOTE: Inspect for shipping damage and notify freight carrier or store where purchased immediately if damage is present. To avoid risk of personal
injury and property damage, if the product appears to be malfunctioning or shows signs of corrosion, call a licensed professional immediately. Current
copies of the Product manual can be viewed at www.amtrol.com. Use proper safety equipment when installing.
THIS IS THE SAFETY ALERT SYMBOL. IT IS USED TO ALERT YOU TO POTENTIAL PERSONAL INJURY AND OTHER
HAZARDS. OBEY ALL SAFETY MESSAGES THAT FOLLOW THIS SYMBOL TO REDUCE THE RISK OF PERSONAL
INJURY AS WELL AS PROPERTY DAMAGE.

IMPORTANT GENERAL SAFETY INFORMATION - ADDITIONAL SPECIFIC SAFETY ALERTS APPEAR IN THE FOLLOWING INSTRUCTIONS.
THIS PRODUCT MUST BE INSTALLED BY A
LICENSED PROFESSIONAL.
Installation
1. Refer to Figure 1 for proper installation of the Amtrol ADS.
Wet weight of the separator can exceed strength
of supports. Make sure provisions are made to
support the wet weight and not just the dry weight (see weight chart
below). Failure to follow these instructions may result in serious or
fatal personal injury and/or property damage.
2. ADS Series Separators can be supported in the piping system as long
as pipe hangers are attached to the nozzles as close to the unit’s shell
as possible.
Welding to the pressure vessel boundary will
void the ASME rating.
3. A blowdown valve should be added to the blowdown connection at the
bottom of the tank. The function of the blowdown valve is to facilitate the
purging of sediment from the vessel.
An automatic, float-type air vent needs to be installed on the top con-
nection of the separator. Install with at least 30” of clearance below unit.
Maintenance
A licensed professional should check the complete system, including
the air separator, yearly and more frequently as the system ages.
Leakage, corrosion or indications of damage are
signs of an impending serious failure of the air
separator. Periodically inspect for damage and, if noted, the separator
must be serviced or replaced immediately. Failure to follow these
instructions may result in serious or fatal personal injury and/or
property damage.
Sediment should be purged from the vessel periodically. This is
particularly true during the initial start-up period. During each purge
cycle, note the condition of the water to determine a regular blowdown
interval. The need to purge sediment from the vessel may be evidenced
by a high pressure drop across the separator or by pump cavitation
problems. To clean the separator:
1. Allow the system water temperature to cool below 100°F.
Water temperature above 100°F can be very
hazardous. Allow system water temperature
to cool down below 100°F before blowing down the separator.
Failure to follow these instructions may result in serious or fatal
personal injury and/or property damage.
2. Magnetic Option only: (Figure 2) Unscrew and remove the Magnetic
rod. Place rod on a nonmetallic surface, away from dirt and
metal objects.
Can be harmful to pacemaker and ICD wearers.
Stay at least 12” away. Magnet exerts strong
forces on metallic objects. Tools, magnets and metal objects can
cut, pinch and entrap hands and fingers. HANDLE WITH CAUTION!
3. Operate the blowdown valve for a few seconds. This should dislodge
accumulated dirt from the vessel. Start by closing the isolation valve to
isolate the separator from the system. Open the blowdown valve on the
bottom of the separator to drain the unit. Make sure that all of the flow
from the blowdown valve has stopped. If water continues to flow, the
isolation valve must be repaired or replaced before proceeding.
System fluid under pressure and/or high
temperature can be very hazardous. Before
proceeding, reduce system pressure to zero and isolate the
separator from the system. Allow system temperature to cool
below 100°F. Failure to follow these instructions may result in
serious or fatal personal injury and/or property damage.
