INSTALLATION PROCEDURE...
STEP 3: Connect electrical power supply conduit to input junction box using suitable conduit
fitting into 3/4” NPT inlet. Install optional area light and indicator light, if desired. For
MODEL 8317CTFP (120V): connect 120 volt AC line to 16 gauge shower wires as
follows: Black = 120 VAC, White = Neutral, Green = Ground.
For MODEL 8317CTFP.220V:
Connect 220 volt AC line to 16 gauge shower wires as follows: Black = 220 VAC,
Red = 2
nd
Hot, Green = Ground. Turn on power supply to complete installation. (See
Electrical Schematic Drawing, Sheet 4 of Installation Drawing).
OPERATING INSTRUCTIONS
Power to the 8317CTFP (120V) & 8317CTFP.220V may be left on year round. The non-
adjustable thermostat will shut off heat cable when air temperature rises to 55
º - 65º F (12º - 18º
C).
Heat cycle will repeat when air temperature drops to between 45º -55º F (7º - 13ºC).
Periodic check of water temperature from shower or eye/face wash will confirm normal
operating temperatures between 45
º- 95ºF (7º-35ºC).
This unit is heated by low power heat trace cable suitable for freeze protection but not suitable
for providing a warm shower from a cold water supply. Moments after activating shower, water
temperature will drop to supply temperature.
ANSI recommends a comfortable shower temperature range of 60
ºF (15ºC) to 100ºF (38ºC). For
the protection of the user, we strongly recommend that some system be installed to provide
tempered (warm) water to this shower and eye/face wash. Heat trace cable used on this
shower heats slowly and may take 90 minutes to complete a full heat cycle.
No drain connection at bleed valve(s) is normally required. Valve(s) will remain closed unless
power outage, high ambient temperature (with optional scald protection valve, only) or
malfunction occurs (see Troubleshooting).
NOTE: IF GROUND WATER IS BELOW 38ºF (3.3ºC) SIMPLY TESTING SHOWER MIGHT
CAUSE BLEED VALVE TO OPEN. ONCE OPENED, COLD GROUND WATER WILL KEEP
BLEED VALVE OPEN. SEE TROUBLESHOOTING GUIDE FOR PROCEDURE TO CLOSE
BLEED VALVE ONCE OPENED.
Periodic tests for proper function of shower and eye/face wash should be performed and
recorded on inspection tags attached to unit or in separate maintenance logbook (preferred).
IMPORTANT SAFETY NOTICE
THE NATIONAL ELECTRICAL CODE REQUIRES GROUND-FAULT EQUIPMENT
PROTECTION ON EACH HEATING CABLE BRANCH CIRCUIT. TO REDUCE THE RISK OF
FIRE CAUSED BY DAMAGE OR IMPROPER INSTALLATION, CIRCUIT BREAKERS SUCH
AS SQUARE D QO-EPD AND QOB-EPD OR EQUIVALENT, WITH A 30mA TRIP LEVEL,
SHOULD BE USED. PLEASE SUBSTITUTE THESE BREAKERS WHEREVER REFERENCE
IS MADE TO CONVENTIONAL BREAKERS IN THIS DOCUMENT. ALTERNATIVE DESIGNS
PROVIDING COMPARABLE LEVELS OF GROUND-FAULT PROTECTION MAY ALSO BE
ACCEPTABLE.
