General information for all sizes
HFor narrow passageways, remove
upper and lower portion of crating and
carry DHW tank to its installation
location by means of crating boards
mounted on the tank.
HPosition tank carefully and remove
wood crating.
HLeave adequate clearance to the wall
or other objects enabling easy access
to the aquastat (where applicable).
HLocate tank(s) on flooring or
foundation capable of supporting the
weight of the tank(s) filled with
water.
HThe tank does not require a special
foundation and can be placed directly
on the floor. If, for cleanliness
purposes, the tank is to be kept off
the floor, a foundation can be used for
each tank or tank battery.
HLevel tank using leveling bolts on tank
frame.

bottoms out inside the sensor well,
and secure with the spring-clip.
7. Position the insulation jacket on the
DHW tank, then fit the top panel.
8. Press the logo (from the accessory
pack) into the lid.
9. Cover the hole beneath the

Multiple Tank Set-up only for 79 and 120 USG / 300 and 450 ltr capacities
Two tanks, each with 79 USG / 300 ltr content, or up to four tanks, each with 120
USG / 450 ltr content, may be installed side-by-side.
The tank battery is controlled via one DHW tank aquastat. Individual control of
tanks within the tank battery is therefore not possible.
If control of individual tanks within a battery is necessary, two alternatives exist.
Either a 4-tank battery can be separated into smaller batteries, i.e. two batteries
each consisting of two tanks (one DHW tank aquastat controls each battery), or all
tanks should be installed individually, i.e. individual tank set-up (one DHW tank
aquastat controls each tank).

1. Install aquastat in the boiler water
supply of the last tank receiving the
boiler water of the tank battery (see
illustration).
2. Install domestic cold and hot water
header lines (see illustration).
3. Install boiler water supply and return
header lines (see illustration).
4. Make final cold and hot water
connections.
Both the boiler supply/return header and
the domestic hot/cold water header must
be installed in a reverse return method.
This ensures uniform heating of all tanks
in the battery. Header sizes for batteries
up to four 79 to 120 USG / 300 to
450 ltr tanks are printed on
the following page.
5. Insulate header piping lines.

IMPORTANT
In commercial installations, we
recommend the installation of an
additional high limit aquastat in the
main discharge pipe of domestic hot
water from the tank battery into the
system, and to wire this additional
high limit aquastat in series with the
operating aquastat.
