HIGH TEMP. LIMIT STOP

Installation Continued
■
Set the Limit Stop (See Figure 5)
The handle rotation setting must be adjusted to limit the
distance the user can rotate the handle towards the full
hot water position.
CAUTION: Any repair or modification of the valve will affect the
high temperature setting. Any changes in inlet water temperature
will require readjustment of the limit stop.
16. Remove the valve handle.
17. Adjust the valve to the desired maximum outlet
temperature (110°F (43°C) max). Screw on the high
temperature limit stop until it touches the stem shoulder.
18. Turn the stem clockwise until the water stops.
Open valve to full hot position and verify maximum
outlet temperature setting.
19. Replace handle. Repeat steps 17 through 18 until desired
maximum outlet temperature is reached. Remove handle
before final assembly of shrouding.
Assemble the Valve Cover and Handle
20. (Figure 4) Fit the dial insert onto the shrouding and secure
to the shroud and valve at D with the 2-1/4" screws.
21. Slide the O-ring and sleeve over the bonnet. Place the
lever over the stem, and secure with retaining screw
using Allen wrench.
22. (Figure 4) Finish assembly by tightening the shrouding
screw at A above the showerhead.
Servicing the HydroPanel ® II Unit
■
Before servicing checkstops or piping, turn off the supply water
upstream. To access the checkstops, remove the valve handle
assembly, cover plate and shrouding (refer to Install the
Piping Assembly).
At least every twelve months, open up the checkstops and
check for free movement of the poppet.
Before servicing the valve, either turn off the water supply
upstream (the shroud does not have to be removed), OR access
and close the checkstops. To close the checkstops, turn the
adjustment screw on each fully clockwise.
Every twelve months, remove the valve bonnet and check the
internal components for freedom of movement.
To service or clean the showerhead, unscrew from shroud
at hex nut. Service as necessary, and reattach.
Troubleshooting
■
Note: For complete servicing the Series e700 Valves or Integral
checkstops, please refer to Technical Instructions Form TI e700.
What to look for if:
The maximum temperature cannot be obtained...
a. Lime deposits may have accumulated in the hot water
pipes, restricting the hot water supply.
b. The hot water supply temperature may be too low.
c. The handle rotation setting may be too low. Remove valve
handle, and readjust the high temperature limit stop.
Flow of water is less than desired…
a. The upstream supply valves may not be fully open.
b. The inlet supply pressure(s) may be low.
c. The showerhead may be clogged. Remove and clean
the showerhead.
d. The checkstops may be clogged.
The valve opens with hot water fl ow rather than
cold water fl ow...
a. The inlet water supplies are connected to the wrong
ports or cartridge is installed improperly.
The tempered water is too cold, although cartridge has been
replaced, OR the hot water temperature is below 115°F...
a. Raise the temperature of the hot water supply.
Flow of water is completely shut off...
a. The upstream supply valves may be completely closed.
b. The hot or cold water supply pressure may have failed.
The e700 valve is designed to close down upon cold
water supply pressure failure.
c. The checkstops may be closed. Access the checkstops
and open by turning the adjustment screw fully
counterclockwise.
