Peration
This thermal expansion tank is designed to maintain safe
water pressures in a domestic water heating system that
utilizes a backflow preventer or check valve. It features a
butyl rubber diaphragm and polypropylene liner to sepa-
rate the system water from the tank’s inner walls and
pre-charge. The system connection is stainless steel
and the tank is finished with an appliance quality paint to
minimize corrosion.
W
hat it does
Adding a backflow preventer, water meter with a check
valve, or any other “no return” valve to a domestic water
heating system creates a closed loop system. When water
heats up, it expands which can cause unsafe operating
pressures and cause nuisance operation of the water
heater’s safety relief valve.
Adding a thermal expansion tank to the cold water inlet
of the water heater creates a reservoir for the expanded
water. Water enters the tank and is released back into the
system on demand. The goal is to avoid dripping relief
valves and improve the safety of the system.

Explosion Hazard
This expansion
tank is designed for water storage at a
maximum pressure of 150 psi and a maximum temperature of 200 F.
A properly sized pressure relief valve set at a maximum of 150 psi must
be installed in the system. This tank is shipped with a pre-charge of 40
psi and any adjustment to the pre-charge must be done prior to
installation and at ambient temperature. Do not adjust the pre-charge of
this tank if the product is corroded or damaged or shows any signs
of diminished integrity. The maximum allowable pre-charge in this
expansion tank is 80 psi. Do not adjust the pre-charge of the expansion
tank with the system under pressure. Failure to follow these instructions is
UNSAFE and may result in serious injury or death and or property damage.
This expansion tank and the associated
piping may in time leak. This tank must be
installed in a location that allows for easy access, visual inspection and
where water leakage will not cause property damage. Installation must
include a means for adequate drainage. This tank must not be installed
in a location that is subject to freezing. This tank must be installed in the
vertical position. The manufacturer of this product is not liable or
responsible for any water damage associated with the installation and or
failure of this product. Failure to follow these instructions will void the
warranty and may result in personal injury or property damage.
This tank is intended for use on potable
water systems only and any other use may
be dangerous and will void the warranty. This product’s performance and
lifespan can be significantly and adversely impacted by aggressive water
conditions. A water test should be conducted at regular, periodic intervals
specifically looking for corrosive water, acids and other relevant water
contaminants which if present must be treated immediately and appropri-
ately. The system piping must be properly grounded to earth and a di-
electric union is recommended in the installation. Failure to
follow
these
instructions may result in serious injury or death and or property damage.
