A separate breaker is required for the heater (8.5 A @ 120 VAC 60 Hz). For more information,
refer to FE-356 Atlas Retail/Commercial Dispenser Field Wiring.
Note: Heaters are thermostatically controlled and will cycle between on and off during cold
weather to maintain a minimum cabinet temperature.
Sealing ‘Y’ Fittings
‘Y’ seals are installed in conduit runs to minimize passage of vapors, gases, or flames from
one portion of the electrical installation to another through the conduit. Fittings must be
installed in accordance with Articles 501-5 and 502-5 of the National Electric Code and fitting
manufacturers’ instructions.
DEF is non-flammable and creates no explosive vapors. Therefore, installation requirements
for DEF units differ from units that handle hazardous fuels. However, electrical safety
requirements are applicable. If a DEF unit is installed in the Class 1 Division 2 hazard zone of
a pump/dispenser delivering flammable fluids, consult Gasboy Technical Support to determine
requirements for installing DEF units in that area. Generally the unit must be installed to
comply with requirements for units handling flammable fluids for the area within the hazard
zone.
Gasboy uses Killark Type EY fittings and recommends them or their equivalent for vertical
conduit runs. The following sealing directions are for Killark fittings only and instructions
may vary for other manufacturer’s fittings. Read through all instructions completely before
beginning.
