Aerco 505 GAL. Technical Instructions

1. INTRODUCTION

AERCO storage tanks are ASME certified glass-lined pressure vessels designed for use with
instantaneous water heaters. When contending with challenging applications, they assure
consistent hot water service during peak demands. The AERCO storage tanks are available in
standard stratified or accumulator storage configurations.
Incorrect installation can cause rapid failure of water tanks due to
electrolysis. It is vital that this risk is reduced by the use of
dielectric connections, isolation of the tank supports, and regular
anode servicing. Installers must be aware of correct procedures.
For assistance please call: 1-800-526-0288.
Overspray on topcoated tanks may hide some fittings. Prior to
filling the system, check all fittings and connections and compare
fitting locations to the approved drawing to ensure all fittings are
capped, sealed or piped to.

2. STORAGE TANK TYPES

The AERCO water storage tanks come as standard, stratified storage tanks or accumulator
storage tanks.
Stratified storage tanks (see Figure 1):
•
These tanks come with either a dispersion tube or baffle at the cold water inlet to
achieve a thermal boundary layer.
•
Models with threaded cold water connection are equipped with a dispersion tube.
•
Models with threaded cold water connection have a 3" Male NPT inlet
•
Models with 150 lb. flanged cold water connections are equipped with a baffle.
Accumulator storage tanks (see Figure 2):
•
These tanks DO NOT come with a dispersion tube or baffle.
•
Models with threaded cold water connection have a 3" Female NPT inlet
Standard storage tanks (see Figures 3 – 5 for dimensions):
•
Dispersion tank is optional.
