Energy recovery COMPONENT rated in

accordance with AHRI/ANSI Standard 1060-2005

and certified to AHRI. Actual performance in

packaged equipment may vary.

ERV Unit with Millennium® Packaged Unit

246681-YTG-C-0611

FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE

ETL Certified per UL 1995 and CSA 22.2

DESCRIPTION

• Reduces cooling load at design temperatures up to 4 tons per

1000 cfm of outside air.

• Reduces heating load up to 2.5 Tons Btuh per 1000 CFM of out-

side air.

• Dry energy transfer. Moisture in supply (intake) air stream is

transferred to exhaust air stream in a vapor state, eliminating

condensate plumbing from the UERV.

• Attaches directly to the York rooftop units. All mounting equip-

ment is provided.

• Separate fused power supply. (Except Millennium or VR74 or

VR122)

• Filters / mist eliminators are provided on the entering air open-

ings.

• Adjustable support legs are provided.

• Two modes of operation (Pivoting Wheel Models only)

• Recovery mode during normal energy recovery operation.

• True economizer mode when outside sensor calls for

economizer operation (3 - 12.5 ton packaged units

equipped with economizers). U. S. Patent 5,548,970.

• Pivoting wheel models used with packaged unit with econo-

mizer. Sequence of operation controlled by economizer control-

ler. (Small Sunline and Predator Only)

• Balancing dampers provided on VR, VH and VU Modules.

(Except Millennium or VR74 and VR122)

• Centrifugal blowers (both intake and exhaust for high static

capability and low sound levels). (Except Millennium, VR74 and

VR122)

• Heavy gauge galvanized steel cabinets corrosion protected with

powder paint process that match York units.

• Fully insulated cabinet.

• AHRI certified internal enthalpy wheel is provided.

• Internal enthalpy wheel made of polymeric material with silica

gel impregnated into the material. The enthalpy wheel has a

five year limited warranty.

• Internal enthalpy wheels are easily cleanable. Large wheels (25

inch diameter and above) are split into easily removable pie

segments. Smaller wheels can be removed from the ERV.

• Continuous operation down to 10 ºF (-12 ºC) without defrost at

indoor relative humidity up to 40%. For temperatures below 10

ºF (-12 ºC), Optional Low Ambient Control Kit is required. Kit

includes temperature sensor to control the ERV before frost

build up can occur on recovery wheel.

Note: MAXA-MI$ER

UERV’s are designed for use with

rooftops using 14” high or greater roof curbs.

Note: Predator models ZF/ZH/ZJ/XP* 037-150, with

ERV must use “slab” type economizers and

downflow position.

246681-YTG-C-0611 APPLICATIONS Critical Terms for Standard 1060 are as follows: Unitized Energy Recovery Ventilators (UERV) are used with the York rooftop packaged units. The internal wheel provides sensible and latent energy exchange between the entering and exhaust air streams of a building. This allows a substantial amount of the energy, which is normally lost in the exhaust air stream to be returned into the entering air.

246681-YTG-C-0611 CROSS LEAKAGE IN UERV’S (PURGE SECTORS) The issue of cross leakage in rotary wheel based UERV's used in space conditioning applications is often misunderstood. As a result, many systems are installed with purge sectors and the additional fan capacity required to allow these sectors to function when in fact they are unnecessary.
