Installation C2N Series Tankless Heater
Bradley • 215-1821 Rev. B; ECN 16-17-005 5/3/2016
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.
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 4–20ma communication interface with temperature controller.
TE & TE2 Corrosive Fluid Protection: The TE option is a PFA Teflon
®
coated heat exchanger with bright 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): Keltech'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 (L5): 0.50 GPM (1.9 lpm) option 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.
If a trip occurs under normal operation DO NOT RESET Ground Fault without evaluation and
service.
Normal state is Ground Fault light OFF, Bank Ready lights ON.
