WARNING: Electrical Shock and potential circuit damage. Disconnect power supply before beginning installation.
Failure to follow these instructions could result in serious personal injury or death and property damage.
Improper wiring and wire can cause electrical shock and fires. Wiring connections must be made in
accordance with all applicable electrical codes and ordinances. Use copper wire only. Failure to follow these
instructions could result in serious personal injury or death and property damage.
Potential electrical overload. Each circuit is limited to a maximum of 3 amps and 1/3 HP. The
combined load for the controller is limited to 15 amps and 1 HP maximum. Failure to follow these instructions
could result in serious personal injury or death and property damage.

SAFETY INSTRUCTIONS
This safety alert symbol will be used in this manual to draw attention to safety related instructions.
When used, the safety alert symbol means: ATTENTION! BECOME ALERT! YOUR SAFETY
IS INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN A
SAFETY HAZARD.
TANK PLACEMENT REQUIREMENTS
A level location with 36" of clearance on the front of tank required. This
allows enough room to hook-up the manifolds for the Hydronic Zone and
Water-to-Water Heat Pump. An allowance for 36" of clearance on the top of
the tank (between lid and ceiling) for insertion of an optional flow meter tool,
which is recommended. Buffer Tank location shall be in a conditioned air
space to prevent condensation.
ELECTRICAL SERVICE & CONNECTIONS
The HSS
®
Buffer Tank requires a dedicated 20 amp, 120 volt circuit. The
primary wiring must be in accordance with Local Codes and that of the
National Electric Code. Low voltage wiring must be isolated from primary
voltage lines and connections.
The individual circulator pumps for the Hydronic Zones are pre-wired and
labeled at the control panel for field connections, these pumps are factory
assembled for 120 volts. The Water to Water (load side) circulator pumps shall
be wired to the heat pump’s control box; (see heat pump manufacturers wiring
diagram for proper wiring connections) and are typically wired with the
compressor contactor load side. Follow the color-coded schematic of low
voltage wiring. (see page 7)
WARNING: Load side circulator pumps are 220 volts. It is important to tag the Buffer Tank as having
separate power sources for servicing.
WARNING: HSS
®
Buffer Tank is a non-pressurized unit and should never be pressurized.
