CAUTION
SAFETY HAZARD! Sharp Edge Hazard. Be careful of
sharp edges on equipment or any cuts made on sheet metal while
installing or servicing. Personal injury may result.
CAUTION
1.1 WARNINGS
IMPORTANT: Read this manual carefully before attempting to install,
operate, or perform maintenance on this hydronic coil. Installation,
service, and maintenance should be performed by qualied technicians
only.
NOTE: “Warnings” and “Cautions” appear at appropriate places in this
manual. Read these carefully. Your personal safety and the proper
operation of this heating product require that you follow them carefully.

WARNING
SCALD HAZARD!
THIS SYSTEM CONTAINS HOT WATER AND OPERATES UNDER
PRESSURE. WATER TEMPERATURES ABOVE 125°F CAN INSTANT-
LY CAUSE SEVERE BURNS OR DEATH.
USE CAUTION WHEN SERVICING THIS EQUIPMENT. ALLOW SUF-
FICIENT TIME FOR THE WATER TO COOL BEFORE OPENING THE
SYSTEM DRAIN. FAILURE TO FOLLOW THIS WARNING COULD
RESULT IN SERIOUS PERSONAL INJURY, PROPERTY DAMAGE, OR
DEATH.
s
s
WARNING
LEAK HAZARD!
IF THE HYDRONIC COIL HAS A LEAK, USE CAUTION WHEN
SERVICING THIS EQUIPMENT. THOROUGHLY WIPE OFF EXCESS
WATER FROM ALL COMPONENTS AND ALLOW ADEQUATE TIME
FOR THE COMPONENTS TO DRY COMPLETELY BEFORE SERVIC-
ING SYSTEM.
FAILURE TO FOLLOW THIS WARNING COULD RESULT IN SERIOUS
PERSONAL INJURY, PROPERTY DAMAGE, OR DEATH.
1.2 CAUTIONS
s
s
WARNING
SAFETY HAZARD!
REMOVE ANY ELECTRICAL STRIP HEATERS WHEN INSTALLING
THE HYDRONIC HEATER COIL. ELECTRICAL AND HYDRONIC
HEAT MUST NOT BE USED TOGETHER. FAILURE TO FOLLOW
THIS WARNING COULD RESULT IN SERIOUS PERSONAL INJURY,
DEATH, OR PROPERTY DAMAGE.
FREEZE HAZARD! Installations subject to freezing
ambient temperatures must have provisions for freeze protection to
avoid damage to this appliance.
CAUTION
SAFETY HAZARD! The selected location and orientation
of the air handler and hydronic coil must allow the hydronic heating
unit's circulator pump to be positioned with the motor shaft horizon-
tal. Do Not install the hydronic coil with its service panel and the
circulator pump facing vertical, up, or down.

IMPORTANT - Follow all National and local codes when
installing this hydronic coil.
This accessory hydronic coil is designed to deliver primary or
secondary heating capacity and can be used in either a po-
table or non-potable water system. Maximum entering water
temperature is 180 °F.
1. Check the hydronic coil nameplate to conrm that the se-
lected hydronic coil is approved for use with the air handler.
2. Check the components received for damage. Report any
defects or shortages to the transportation company im-
mediately.
NOTE - Since the hydronic coil mounts over the discharge
end of the air handler, it is necessary that the equipment
power enter from one of the side conduit entry points.

STEP 2 - Place hydronic coil on top of the air handler
cabinet.
1. Flip coil over so the gasket is on the bottom and the
supply side anges are facing up.
2. Set the coil on top of the air handler.
3. Align the coil with the air handler case.
Section 4. Install Hydronic Coil
STEP 1 - Place the hydronic coil with the supply side
facing down. Apply gasket material onto the coil
flanges. On the front flange, the gasket material must
be at the inner edge to create an airtight seal.

Section 5. Piping
NOTE - The hydronic coil can be installed in upflow,
downflow, or horizontal positions. When the air han-
dler is installed in the horizontal orientation, an addi-
tional strap must be used on the coil section.
STEP 1 - Attach piping to the hydronic coil.
1. Piping must consist of two vertical pipes or two
horizontal pipes.
2. Use a low temperature braze solder to attach pipes.
NOTE - The recommended piping directions are
upward, and to either the right or left side when in the
upflow orientation.
In all orientations, the water lines should not cross
over the air handler unit.

NOTE: Air flow can be adjusted by discreetly control-
ling the W1, W2, & W3 inputs to the AFC with multi-
stage thermostats. See additional notes on wiring
diagram.
Example: TAM9A0C36 with BAYWACC08
hydronic heating coil
W1 input = 396 cfm
W1 + W2 input = 792 cfm
W1 + W2 + W3 input = 1200 cfm
Placing a jumper across all W inputs will re-
sult in the maximum airflow for the combina-
tion of heating coil and air handler.
