C1N Series Tankless Heater
Output heating capacity is reduced if these heaters are installed on 415V, 400V or 380V 3-ph .
Contact the factory to supply this information .
Satisfactory performance of the heater is dependent upon a specific flow rate vs temperature rise capability . If
the desired temperature is not achieved, please verify the following:
1 . Circuit breaker is on and rated for the maximum power draw .
2 . Heater is drawing the proper current for the supply voltage on all 3 phases .
3 . All 3 phase indicator lights are lit (not flashing) indicating maximum power draw and maximum
amperage is being drawn .
4 . Flow rate and temperature rise in the water heating process are compatible with the heater specifications .
5 . Verify there is no additional supply of cold water entering the line downstream of the heater .
Product Options
GF (Ground Fault): Detects electrical leakage from external sources to protect equipment, electronics, and
the heat exchanger from being damaged in the event of a power fault . After turning on water, then power, test
ground fault:
1 . Press GF Test button .
2 . Watch for ground fault light to illuminate and Bank Ready light(s) to shut off . The Ground Fault system is
active and in working order .
3 . Press the GF Reset button, hold for 2 seconds and release to reset ground fault .
NOTE: If a trip occurs under normal operation DO NOT RESET Ground Fault without evaluation and service.
NOTE: Normal state is Ground Fault light OFF, Bank Ready lights ON.
FDS Fused Disconnect: Internal fused disconnect interlocks with enclosure door when energized, prohibiting
access to a live cabinet . Select the FDS option for an additional level of safety and convenience at the heater
location .
T190 High Temperature Option: Reach and maintain temperatures as high as 190°F (88°C) .
D1 Control Interface: Provides 4–20 ma communication interface with temperature controller .
TE & TE2 Corrosive Fluid Protection: The TE option is a PFA Teflon
annealed stainless steel elements, FDA Approved (use for deionized water or mild corrosive fluid applications) .
Similar to TE, the TE2 option is a single layer of Xylan Fluoropolymeric coated heat exchanger with bright
annealed stainless steel elements, FDA Approved for Food Contact (use in deionized water applications) .
EXP2 (Explosion Proof Purge System): Bradley's EXP2 option makes heaters compliant for classified areas;
Class I Division 2, Groups A, B, C, D, Temp Code: T5 . The Purge System requires a supply of clean instrument
air or inert gas (provided by installer) . This supply maintains a positive internal pressure and prevents the
enclosure from filling with flammable gases, dusts or vapors from the ambient environment . Complete
installation provided in this manual .
Low Flow (L25 & L5): Options include 0 .25 GPM (1 .0 lpm) and 0 .50 GPM (1 .9 lpm) for heating water when lower
flow rates are required .
N4X (NEMA 4X Enclosure): Corrosion resistant enclosure made of stainless steel and ideal for harsh
environments .
