Vapor Tight Lights - Greenheck Vektor-M Compact ERS Installation, Operation And Maintenance Manual

Vent and drain connections are provided on Greenheck water coils unless otherwise specified. This allows the
coils to be drained. Keep in mind that when draining the coils, all water may not drain from the coil. In order to
completely drain the coil to prevent the possibility of freezing during cold ambient temperatures, air or nitrogen
pressure must be utilized to blow any remaining water from the coil.
Coil Installation Checklist
Use the following checklist to verify that all necessary installation procedures have been completed.
1. Coils are installed with airflow in same direction as indicated on the coil nameplate or casing.
2. Condensate drain pans and piping are installed with a trap in the condensate line and piping is insulated and
heated if installed in applications that are below freezing.
3. Clean filters are installed upstream.
Optional Accessories (
Dirty Filter Sensor (Magnehelic Gauge)
Dirty filter sensor monitors pressure drop across the exhaust air filters. Visual gauge on the side of the plenum
cabinet indicates the pressure across the filter section. Periodic inspection is necessary to determine whether filters
need to be replaced.

Vapor Tight Lights

Vapor tight lights provide light to each of the compartments in the energy recovery plenum. The lights are wired to a
junction box mounted on the outside of the unit. The switch requires a separate power source to allow for power to
the lights when the unit main disconnect is off for servicing.
Electrical Package
The electrical package consists of a switch and GFCI receptor mounted in a two gang, "in use" NEMA-3R rated box
with cover plate. This box would be mounted at the factory near the ERS plenum access doors.
The GFCI is rated for 15A, 125 VAC and is provided with SafeLock™ Protection. This feature denies power if the
GFCI is incorrectly wired or if the GFCI is damaged and protection is lost. The GFCI is also equipped with a trip
indicator light to easily identify a tripped condition. Receptor uses a NEMA 5-15 R configuration.
Supplied switch is industrial extra heavy duty grade with back and side wiring. The switch has a rating of 20A,
120 / 277VAC and single pole. The switch comes from the factory pre-wired to lights within the ERS plenum section.
Electrical wiring for power to the electrical panel is to be installed by a licensed electrician in compliance with all
local and national codes.
