PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY
IMPORTANT GENERAL SAFETY INFORMATION - ADDITIONAL SPECIFIC SAFETY ALERTS APPEAR IN THE FOLLOWING INSTRUCTIONS.
THIS PRODUCT MUST BE INSTALLED BY A
QUALIFIED PROFESSIONAL.
Installation
1. Refer to Figure 1 for proper installation of the Amtrol ADS in a boiler
system or Figure 2 in a chilled water system.
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
connection of the separator.
Maintenance
A qualified 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. 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.
