INSTALLATION INSTRUCTIONS
SERIES 440 FOTOPANEL
1. Flush all piping thoroughly before installing.
2. Remove knobs A, B, and C.
3. Remove the four-bracket screws (D) and panel screws
(E) then remove stainless steel box assembly. Do not
remove front panel from box.
NOTE: There are six (6) bracket screws on the pres-
sure equalizing models.
4. For wall mounting, use rough-in drawing to locate
mounting holes on wall. Mount bracket to wall. Do not
remove mixer assembly from bracket.
5. Make final connections to hot and cold supplies and
outlet from vacuum breaker. Facing front of mixer,
connect hot water to left side (marked HOT) and cold
water to right side (marked COLD). Inlet connections
must be piped correctly for proper operation of
Fotopanel. NOTE: Do not exert excessive torque on
the outlet pipe when connecting it to the vacuum
breaker which is supported by a plastic manifold.
6. Replace stainless steel box assembly and attach
knobs A, B, and C and the front panel screws E.
1. If thermometer should need calibration, remove front
knobs A, B, and C and the front panel screws E.
2. Calibration screw is located on back of thermometer
case.

4. Maintenance Features

The POWERS™ Series 440 FOTOPANEL is a mixing valve designed for precise temperature control in various applications. It ensures a consistent tempered water supply by blending hot and cold water, offering both standard and high-capacity models (440-1000 and 440-3000 respectively).

Function Description:

The FOTOPANEL operates by mixing hot and cold water supplies to deliver tempered water at a user-defined temperature. It features a thermostatic mixing element that automatically adjusts to maintain the set temperature, even with fluctuations in incoming water pressure or temperature. The device includes a front panel with knobs for temperature adjustment (WARMER/COOLER) and volume control. A key safety feature is its ability to close down upon cold water failure, preventing scalding. The valve is designed for wall mounting and includes a stainless steel box assembly for a clean installation.

Important Technical Specifications:

• Models: Series 440 FOTOPANEL (440-1000 standard capacity, 440-3000 high capacity).
• Capacity:
  • 440-1000: 6 gpm (gallons per minute)
  • 440-3000: 14 gpm
• Inlet Connections: 1/2" Hot Water Inlet, 1/2" Cold Water Inlet.
• Outlet Connection: Connects to a vacuum breaker.
• Temperature Range: Factory set to deliver tempered water up to a maximum of 110°F (43°C) with equal supply pressures (hot water 140°F/60°C, cold water 60°F/16°C). The maximum temperature setting is adjustable.
• Mounting: Wall-mounted with a stainless steel box assembly.
• Components: Includes a wax element, cartridge assembly, bonnet assembly, and various knobs and screws for operation and installation.

Usage Features:

• Temperature Control: Users can adjust the tempered water temperature using the "WARMER/COOLER" knob on the front panel.
• Volume Control: A separate knob allows for adjustment of the water volume.
• Easy Installation: The device is designed for straightforward wall mounting. Installation involves flushing piping, removing knobs and the stainless steel box, mounting the bracket to the wall, connecting hot and cold supplies (hot to the left, cold to the right), and then reassembling the box and knobs.
• Calibration: The thermometer can be calibrated if needed by accessing the calibration screw on the back of the thermometer case after removing the front panel and knobs.
• Maximum Temperature Limit Stop: The valve includes an adjustable high-temperature limit stop to prevent users from setting the temperature too high, enhancing safety. This stop is located on the bonnet and can be adjusted during installation or maintenance.

Maintenance Features:

• Troubleshooting Guide: The manual provides comprehensive troubleshooting steps for common issues such as:
  • Inability to achieve maximum temperature (e.g., lime deposits, low hot water supply temperature, incorrect knob rotation setting).
  • Reduced water flow (e.g., clogged supply valves, low inlet pressure, clogged cartridge, clogged fixture head, clogged checkstops).
  • Valve opening with hot water flow rather than cold (e.g., incorrect inlet connections).
  • Tempered water being too cold (e.g., low hot water supply temperature).
  • Complete shut-off of water flow (e.g., closed supply valves, pressure failure, closed checkstops).
• Component Replacement: Key components like the cartridge assembly, wax element, and bonnet assembly are replaceable using specific repair kits.
  • 440-1000 Repair Kits:
    • Bonnet and Stem Assembly: 420-454
