The LE6XRT is available in either single-wall or double-wall construction.
See Digit 11 of the
Configuration Code.
The sheet metal exterior of the unit is constructed of 20 gauge galvanized steel, if left unpainted.
All units are lined with 2 inches of high density fiberglass insulation in the floor of the unit and 1 inch
of insulation elsewhere. The insulation used has an R-value of 4.3 per inch.
All units are equipped with lifting lugs for hoisting by a crane and all units have integral openings
located in the unit base for use of a fork lift.
Each unit is equipped with hinged access doors on both ends.
Three options are offered for exterior finishes of the unit (
see Digit 24 of the Configuration Code
):
• None (galvanized)
• White paint
• Custom paint
Each LE6XRT unit is equipped with 2 belt-drive blower / motor packages as standard. The motors are
TEFC Premium Efficiency. Motor sizes are specified by the customer at time of order.
See Digits 14 and
15 of the Configuration Code
. The motor and blower assembly is mounted on rails with either neoprene
vibration isolators or spring vibration isolators, depending on the option selected at time of order.
See
Digit 10 of the Configuration Code.
Dampers are specified by the customer at time of order. Order options are:
• None
• Dampers both airstreams
• Damper EA/RA airstream
• Damper FA/OA airstream
See digit 18 of the Configuration Code.
Every LE6XRT ERV is equipped with six L125-G5 enthalpic cores. All cores are similar in construc-
tion.
See Digit 6 of the Configuration Code.
The cores used in all
ERVs are 5th gen-
eration, static plate
enthalpic cores. They
are commonly referred to in
this manual as “cores”.
2.6 FILTERS
Filters are an essential part of the ERV and the ERV should never be operated without properly installed
filters. Filters are typically shipped loose inside the unit. The standard filter is a 2 inch thick MERV 8.
Optionally available are 4 inch thick MERV 8, 2 inch thick or 4 inch thick MERV 13 filters.
Fan speed control is accomplished by either adjustable sheaves on the fan motors, by an optional VFD
or a combination of a VFD and microprocessor controls. Units equipped with VFDs have fixed-diameter
sheaves.
See Digit 19 of the Configuration Code.
2.6.1 Filter Monitors
LE6XRT ERVs can be ordered with optional filter monitors. When the monitor system detects increased
pressure drop across the filters, it provides an indication that the air filters are partially clogged and
require changing.
See digit 22 of the Configuration Code
. Note that units ordered with integrated pro-
grammable controls have filter monitoring supplied.
All LE6XRT units are furnished with weather hoods with integral bird screens for both the OA and EA
openings in the sides of the unit. The hoods are to be field-installed. See photos on previous page.
