Amtrol SPT-28 - Manual (Page 2)

Pre-Installation
1. Visually inspect the Surge-Trol for any damage. If
damage exists return product for replacement.
2. Remove air cap.
3. For applications with pump start-up creating water
hammer adjust the factory pre-charge setting to 15%
below static pressure.
4. For applications with surge issues created by pump
shut down adjust the factory pre-charge setting to
50% below static pressure.
5. For applications with quick closing valves, please
consult manufacturer for tank location and pre-charge
settings. (401) 535-1216.
6. Replace and tighten cap on air valve.
If adjusting the pre-charge pressure
higher than 55 PSIG the unit must be
tied to the system immediately. Failure to do so could
damage the bladder and void all warranties.
Installation
1. The Surge-Trol should be installed as close to the
offending fixture as possible in applications where
there are issues with a quick closing valve.
2. The Surge-Trol should be installed as close to the
pump as possible in surge applications.
3. Once the Surge-Trol is installed and the pre-charge
adjusted properly, check for any leakage. Make repairs
if necessary
Maintenance
1. A qualified professional should check the complete
system, including the Surge-Trol, yearly and more
frequently as the system ages.
Operation
1. The Surge-Trol is designed to provide surge protection
as well as provide a cushion to prevent water hammer
depending on its application.
2. Water temperature is not to exceed 240°F. or fall
below 35°F.
3. The factory pre-charge setting is 25 PSIG and should
only be adjusted at the time of the installation.
4. System velocity shall not exceed 22 fps.

EXPLOSION OR RUPTURE HAZARD 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. Do not expose Product to freezing temperatures or
temperatures in excess of 240° F. Do not exceed maximum
allowable working pressure 275 psig. Do not adjust the pre-
charge or re-pressure this Product except for any adjustments
required at the time of initial installation, especially if Product is
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 leading to Product
failure, serious or fatal personal injury, leakage and/or property
damage.
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.
