Watts Industries Powers BILTMORE 900 Series Owner's manual

The BILTMORE is a pressure-balancing mixer which delivers
a predetermined mix of hot and cold water by compensating
for pressure fluctuations in the hot and cold water supplies.
The BILTMORE features a poppet design valve as part of a
replaceable balancing cartridge. The poppet-type construc-
tion offers two distinct advantages: It will not stick due to lime
build-up or foreign particles in the supply water, and it has a
quick reaction time. The adjustable maximum temperature
stop prevents overadjustment of the handle.
Safety feature: Should either supply fail, the BILTMORE
closes either hot or cold supply water, to prevent a continued
spray of all hot or all cold water.
Capacity ..................................4.6 gpm @ 45 psi
[15 L/min @ 310 kPa Differential]
Maximum Static Pressure ..............125 psig [862 kPa]
Maximum Inlet Temperature..................180°F [82°C]
Inlet and Outlet Sizes ............1/2″sweat or NPT thread
Rough-in Guide ..................................All Models
Handle Rotation Stop............................All Models
Compliance .....................................ASSE 1016
Certified ..........................................CSA B125
The BILTMORE is particularly recommended for shower
and shower/tub installations in hotels, motels, high-rise
apartments, condominiums, and single-family housing.
Pressure balancing valve (Type P) senses incoming water
pressures and compensates for fluctuations in either to stabi-
lize outlet temperature (1). The entire balancing poppet assem-
bly is contained in a Celcon chamber (2). This chamber is
replaceable as a complete cartridge. The hot and cold are
mixed by the action of the mixing plate (3). As the temperature
adjustment stem is rotated from shutoff to maximum hot water
discharge temperature, the mixing plate passes the required
proportion of hot and cold water to produce the desired water
temperature. With the adjustment stem in its full clockwise
position, shutoff is obtained by closing off both supplies.
The maximum temperature limit stop (located on the bonnet)
allows the user to set the desired maximum discharge temper-
ature. This mixer does not compensate for supply water tem-
perature changes, so any variation in the water temperature
will affect the control point and the maximum discharge tem-
perature setting.
CAUTION: Maintenance of the unit requires resetting of
the maximum temperature adjustment stop. As inlet condi-
tions (pressures and temperatures) vary from site to site and
season to season, failure to properly adjust the maximum tem-
perature adjustment stop can result in excessive hot water
delivery.

DESCRIPTION

What to look for if:
1. The flow of water is less than desired.
a. Valves upstream from supply not full open
b. Low inlet water supply pressure(s)
c. Accumulation of lime deposits in hot water pipes,
restricting flow of hot water
d. Showerhead clogged
e. Low hot water supply temperature
f. Checkstops obstructed or jammed
2. The flow of water is completely shut off.
a. Valves upstream from supply completely closed
b. Failure of hot or cold water supply pressure, the mixer
is designed such as to restrict the flow of water on hot
or cold water supply failure
c. Checkstops are closed
3. The flow is untempered hot or cold water.
a. Hot water supply temperature is too low
b. Diaphragm is ruptured; replace with new balance
chamber
4. The flow of water continues after mixer is shut off.
a. Worn shutoff discs; replace shutoff discs
b. Foreign particles on mixing plate causing scratches;
replace stem and plate
c. Worn discs on inlet ports of balancing cartridge;
replace discs
5. The maximum temperature is low.
a. Accumulation of lime deposits in hot water pipes
restricting flow of hot water
b. Concealed maximum temperature stop is not at
desired adjustment point
c. Hot water supply temperature is too low
6. The valve opens with hot water flow rather than cold
water flow.
a. Inlet water supplies are connected to the wrong
ports; see instructions below on reversed inlets.
Cold into hot, hot into cold
If reversed inlets are required due to back-to-back installa-
tion, close check stops. Remove High Temperature Limit
Stop. Unscrew bonnet. Rotate stem 180. The word “TOP”
stamped on stem must face down toward tub outlet.
Reinstall bonnet. Place High Temperature Limit Stop on
bonnet.
NOTE: Hot and cold inlets should be re-identified for reversed
inlets to avoid confusion during future maintenance.
To service mixer, remove handle and dial assembly. Shut off
water supply at checkstops. Remove sleeve and O-ring,
unscrew bonnet, and remove stem.
To remove balance chamber, use needle-nose pliers. Pull
straight out.
Reassemble; Apply silicone grease to stem assembly (15) at
O-ring (14) and mixing plate face. Also apply silicone grease
to outlet seal (16). Be certain “TOP” stamped on stem is fac-
ing up. Screw bonnet onto body; tighten to 75 in.-lbs. Place
O-Ring on bonnet. Slide sleeve over O-Ring. Turn on water
at checkstops. Replace dial assembly and handle.
To service checkstops, turn off water supplies upstream of
mixer. Unscrew checkstop bonnet nut and remove plunger.
Replace items as required.
