Product Options Guide
Option Suffix Description Who can benefit?
Freeze
Protection
FP
The Freeze Protection (FP) option includes a cabinet heater which continually
monitors temperature and turns on at 40°F to prevent freezing and the
potential of product damage.
The FP option does NOT include heat trace material for the incoming and
outgoing water lines. This must be provided by the plumbing contractor.
Facilities that may experience freezing conditions.
Electrical
Disconnect
Switch
(Non-Fused)
EDS
The Electrical Disconnect Switch (FDS) option allows the heater to be safely
shut down at the heater via a safety lockout.
Facilities requiring a door interlock, OSHA
lockout/tag-out capability, or any facility which
desires a local disconnect integral to the heater.
I.e. industrial locations, schools, laboratories, etc.
Fused
Disconnect
Switch
FDS
The Fused Disconnect Switch (FDS) option allows the heater to be safely
shut down at the heater via a safety lockout with the additional benet of fuse
protection integral to the disconnect.
Facilities with code requirements or other
regulations needing fuse protection.
I.e. industrial locations, schools, laboratories, etc.
Explosion
Proof
EP
The Explosion Proof (EP) option adds Class I Division II protection and,
in some cases, Class I Division I protection as approved by the Authority
Having Jurisdiction (AHJ).
Environments classied as hazardous by Article
500 of the National Electrical Code (NEC).
I.e. grain elevators, tank farms, chemical plants,
reneries, offshore oil drilling rigs, etc.
Ground
Fault Circuit
Interrupter
GFCI
The Ground Fault Circuit Interrupter (GFCI) is a True RMS sensing unit which
continuously monitors the current owing into the heater. In the event of
an electrical hazard where there is an electrical path to ground in excess of
prescribed limits, the GFCI will immediately power down the heater.
This protection can benet all applications.
Stand Kit
SK
The Stand Kit (SK) option is available for locations that are not able to wall
mount the unit, or that require a free standing unit.
Offered for facilities procuring a SafeAdvantage or
SpecAdvantage unit.
Remote
Display
RD
The Remote Display (RD) option moves the control panel off of the heater
itself and positions the display on the exterior of the NEMA 4 or N4X cabinet,
making monitoring or temperature adjustment much easier.
This is offered for all NEMA 4 cabinets.
Siren/Beacon
SB
The Siren/Beacon (SB) option is for safety shower applications and includes
a ashing light and siren assembly which is activated when the heater is
turned on. This option eliminates the need for a water ow switch option to
be attached to the drench shower.
Any facility with strict safety requirements or code
compliance regulations.
Dry Contact
DC The Dry Contact (DC) option allows for remote monitoring of the water heater.
Facilities that have a central monitoring station for
all of the equipment.

NEMA 4
N4
NEMA 4 enclosures are made of painted steel and are used in many applications where an occasional washdown occurs or where
machine tool cutter coolant is used. They also serve in applications where a pressurized stream of water will be used. NEMA 4
enclosures are gasketed and the door is clamped for maximum sealing.
NEMA 4X
N4X
NEMA 4X enclosures are made of 304 stainless steel and are used in harsh environments where corrosive materials and caustic
cleaners are used. Applications include food, such as meat/poultry processing facilities, where total washdown with disinfectants
occur repeatedly, and petro-chemical facilities, including offshore petroleum sites.
NEMA 4X6
N4X6
NEMA 4X6 enclosures are made of 316 stainless steel. NEMA 4X6 enclosures are used in harsh environments where corrosive
materials and caustic cleaners are used. Applications include food, such as meat/poultry processing facilities, where total
washdown with disinfectants occur repeatedly, and petro-chemical facilities, including offshore petroleum sites.
