THERMAQUIET Q & A
FOR INSTALLERS
Q. How is ThermaQuiet piped?
ThermaQuiet is piped with 3/4" supply and return pipe.
Connections to ThermaQuiet from supply/return in 1/2"
(Quick Connect).
Q. Can I use 1/2" pipe for Supply and Return?
No, because the ThermaQuiet is designed to have a high
resistance to flow so that the influence of pipe runs is minimized.
Q.What type of pump must I use?
Any 20 ft head pump (i.e. 0011) should suffice, but a high head
pump must be used.
Q. How manyThermaQuiet’s can I put on a 3/4" circuit?
Depending on the length of run, 2-3 is usually fine. For longer
runs use larger diameter pipe.
Q. How do I know if I have adequate flow?
There should be 8-10 degrees difference between supply and
return. If it is much higher, or if you feel a large difference with
your hand, then you have low flow.
ATTENTION: READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO INSTALL, OPERATE, OR
SERVICETHETHERMAQUIET HEATERS! RETAINTHESE INSTRUCTIONS FOR FUTURE REFERENCE.
INSPECT THE SHIPMENT IMMEDIATELY WHEN RECEIVEDTO DETERMINE IF ANY DAMAGE HAS OCCURRED
DURING SHIPMENT.
PRIORTO INSTALLATION, CHECK FOR ANYVISIBLE DAMAGE.MAKE CERTAINTHAT ANY LOOSE PARTICLES ARE
REMOVED (ESPECIALLY INTHE BLOWER ASSEMBLY AREA).

DATA AND RATINGS
InstallingThermaQuiet
Type DL65-WM & DL145-WM
1. Determine the area on the wall in which the Therma-
Quiet unit will be installed. Reference Figure C for the
DL65-WM or Figure D for the DL145-WM and drill
three 7/16" holes in the marked locations at least 3-4"
above finished floor.
2. Insert three supplied hollow wall expansion anchors
into the three newly drilled holes.
3. Screw theThermaQuiet to framed opening at both
sides using 1/4" screws.
4. If quick connect is not used, solder the 15mm heating
element from the unit to a 3/4" connection.
5. Electrical connections for the wall units are to be made
as shown on page 3.
6. Make final piping and electrical connections (see page
3) to the system.Turn the power switch on, purge of
air, check blower operation, and check for any possible
leaks in the piping.

PIPING
SCHEMATIC
Shown is the
piping schematic
for ThermaQuiet
WM-65 and WM-145.
The reverse-return piping
is self balancing and is
preferable.Add balancing
valves to the conventional
piping arrangement to
insure proper balance.

ELECTRICAL CONNECTIONS
All electrical connections must conform to local
and national codes.
CAUTION! For Supply Connections, use wires
suitable for at least 194°F (90°C).
A single phase motor is used to drive the ThermaQuiet
blower on 115 – 120 V. 60 Hz. Since current drain is very
small, wiring codes for short circuit protection only will
apply.The motor is connected to a circuit board that has
sensors for both air and water temperature.
Diagram 1: Single Fan Motor - DL65-WM
Electrical Connections are to be made to all units following
the diagrams below. Choose the diagram that best suits
your application.
Since the blower runs on allThermaQuiet models only
when the system circulator pumps hot water through
the unit, simply connect it to the 115V line.If water
temperature sensor reads adequate temperature (greater
than 79°F) the blower then starts after a short warm-up
and stops a few minutes after the circulator shuts off.
