Installation Guide

MAINTENANCE:
WARNING: Before operating make sure the thermal expansion relief
discharge is piped to a proper location or drain per instructions. Water
damage can occur from either the manual actuation or the normal
operation of the valve if it is not piped to a proper location or drain.
It is recommended that you manually operate the thermal expansion relief at least once a
year by twisting the knob counterclockwise a quarter turn (valve will snap closed past the
quarter turn rotation). Verify the valve opened and flowed water and then reseated. If this
did not occur, immediately call your plumber for inspection and maintenance.
Deposits and other foreign material may become trapped on the seat of the thermal
expansion relief cartridge or build up in the outlet of the thermal expansion relief. The
thermal expansion relief cartridge can be removed for replacement as follows (see Fig. 4):
1. Verify the system is isolated and drained prior to attempting to remove the thermal
expansion relief cartridge.
2. Unscrew the thermal expansion relief cartridge utilizing a tool to interface with the
lower vertical ribs in the plastic bonnet just above the brass valve body (crescent
wrench adjusted to fit across ribs, etc.).
3. With the thermal expansion relief cartridge removed, inspect the cartridge and valve
body. Clean parts as necessary avoiding damaging the brass seat sealing surface
and cartridge diaphragm.
4. Reinstall the thermal expansion relief cartridge by screwing the plastic bonnet of the
cartridge into the brass valve body.
5. Tighten the thermal expansion relief cartridge into the brass valve body to a torque
value of 62 to 71 inch pounds.
6. Slowly pressurize the TER-1 and look for external leaks.
7. Manually actuate the thermal expansion relief valve as described above for the
periodic actuation. In addition to verifying the valve opened and flowed water and
then reseated, verify there is no external leakage on the TER-1 assembly.
GENERAL
The TER-1 incorporates a ball valve, thermal expansion relief, and
SharkBite connections for easy installation all in one device.
The thermal expansion relief provides for water heater overpressure
protection from thermal expansion of the heated water and is used in
place of (or as redundant protection to) an expansion tank as allowed
by the applicable code.
The thermal expansion relief may routinely discharge small quantities
of water to relieve pressure due to thermal expansion of water in the
system. The thermal expansion relief will automatically shut off after
providing such protection.
The thermal expansion relief is designed to protect a water
system from over-pressure only and should not be used in place
of a Temperature-Pressure (T&P) Relief Valve as required by the
boiler/heater manufacturer and applicable codes/standards.
NOTE: If the thermal expansion relief does not shut off,
immediately call your plumber to check for excessive system
pressure.
INSTALLATION INSTRUCTIONS
WARNING: The TER-1 shall be installed with the flow arrow
pointing towards the water heater (indicating flow into the tank) to
ensure the thermal expansion relief can protect the tank when the
TER-1 ball valve is closed. No other valve of any type shall be
installed between the TER-1 and the tank.

1. Verify the system is isolated and drained prior to attempting to install the
TER-1.
2. Install the TER-1 relief valve in the cold water inlet supply to the water
heater with the orientation of the thermal expansion relief outlet connection
horizontal or pointed downward to ensure the outlet drains dry. Refer to
Connecting a SharkBite Fitting for instructions regarding the SharkBite
features.
Note: The nut securing the ball valve handle may be removed, the handle
rotated 180 degrees, and the nut reinstalled to secure the handle, if needed for
the desired installation location.
WARNING: If excessive pressure is developed in the thermal
expansion relief outlet, the diaphragm on the thermal expansion
relief cartridge may fail resulting in external leakage. The thermal
expansion relief must discharge through an appropriate drain line to
atmospheric pressure.

Installation Instructions
Mode d’installation
Instrucciones de instalación
WARNING: The thermal expansion relief is capable of discharging
large quantities of water via manual or automatic actuation. A drain
line must be connected to the thermal expansion relief outlet, and the
drain line must be routed such that it discharges at an approved
location or building drain per the following installation instructions
and such that water damage is avoided.
3. Install and connect the discharge line on the thermal expansion relief
outlet observing the following:
 The discharge from the thermal expansion relief shall be
conducted to a suitable place for disposal when relief occurs by
installation of a drain line with its terminal end discharging
through an air gap (at least 3 inches) to an approved location or
building drain.
 Do not connect the drain line directly to a sewer line.
 Do not install a shut-off valve in the drain line.
 The drain line shall be piped independent of the water heater relief
valve drain.
 The terminal end of the drain line shall be plain, not threaded.
 The drain line should be as short and straight as possible.
 The minimum internal diameter of the drain line shall be 0.245 inch.
 The drain line shall be oriented downward such that the thermal
expansion relief outlet and drain line will drain dry. [Water collecting in
the drain line could increase deposit formation or potentially freeze and
cause blockage.]
 The drain line shall be appropriately secured to prevent movement of
the line during discharge.
 The material used for the drain line must be known to be serviceable
for the purpose and must conform to applicable codes and standards.
 Refer to Connecting a SharkBite Fitting for instructions regarding the
SharkBite features.

Connecting a SharkBite Fitting:
(see Fig. 2)
1. Cut the desired length of pipe, making sure cuts
are square and even.
2. Deburr the ends of the pipe to remove any sharp
edges. This will ensure that the o-ring will not be
damaged upon insertion of the pipe.
3. Using a depth gauge, mark the pipe. Proper
insertion depths are listed below.
4. Push the pipe into the fitting. The mark you
made on the pipe should rest against the edge of
the fitting.

release the tube.
3. Check the fitting and tube end for damage. If the tubing is damaged or marked, then
cut and use a new section of tubing.
GENERALIDADES
La TER-1 incorpora una válvula de bola, de alivio de expansión térmica
y conexiones SharkBite para facilitar la instalación del dispositivo todo
en uno.
El alivio de expansión térmica protege al calentador de agua contra la
sobrepresión de la expansión térmica del agua caliente y se usa en
lugar de (o como protección redundante para) un tanque de expansión
según lo permite el código vigente.
El alivio de expansión térmica puede descargar periódicamente
pequeñas cantidades de agua para aliviar la presión ocasionada por la
expansión térmica del agua en el sistema. El alivio de expansión
térmica automáticamente cierra la válvula después de dar tal
protección.
El alivio de expansión térmica se diseñó solo para proteger al
sistema de agua de la sobrepresión y no se debe utilizar en lugar
de una válvula de alivio de presión-temperatura (P y T), según lo
requiere el fabricante de la caldera/calefactor y los códigos y
normas vigentes.
NOTA: Si la válvula de expansión térmica no se cierra, llame de
inmediato a su plomero para que revise si hay exceso de presión
en el sistema.
INSTRUCCIONES DE INSTALACIÓN
ADVERTENCIA: La TER-1 se debe instalar con la flecha de flujo apuntando
hacia el calefactor de agua (indicando el flujo al tanque) para garantizar que
el alivio de expansión térmica pueda proteger al tanque cuando la válvula de
bola TER-1 está cerrada. No debe instalar ninguna otra válvula, de ningún
tipo entre la TER-1 y el tanque.
1. Asegúrese de drenar y aislar el sistema antes de intentar instalar
la TER-1
2. Instale la válvula de alivio TER-1 en el suministro de entrada de
agua fría al calefactor de agua con la orientación de la conexión de
salida de alivio de expansión térmica horizontal o apuntando hacia
abajo para asegurarse que los drenajes se sequen. Consulte
Conexión de un adaptador SharkBite para obtener instrucciones
sobre las funciones de SharkBite.
Nota: La tuerca que asegura la manija de la válvula de bola se puede quitar, puede girar
la manija 180 grados y volver a instalar la tuerca para asegurar la manija, si fuera
necesario, para la instalación deseada.
ADVERTENCIA: Si se desarrolla exceso de presión en la salida de alivio de
expansión térmica, el diafragma del cartucho de alivio de expansión térmica puede
fallar y provocar fugas externas. El alivio de expansión térmica debe drenar por
medio de una línea de drenaje apropiada para la presión atmosférica.
