I - Ship ping And Pack ing List

Package contains:

1 - Energy Recovery Ventilator Assembly

II - Ship ping Dam age

Check unit for shipping damage. Receiving party should

contact last carrier immediately if shipping damage is

found.

III - Gen eral

These instructions are intended as a general guide and do

not supersede local codes in any way. Authorities having

jurisdiction should be consulted before installation.

IV - Re quire ments

When installed, the unit must be electrically wired and

grounded in accordance with local codes or, in absence of

local codes, with the current National Electric Code,

ANSI/NFPA No. 70.

V - Ap pli ca tion

These Energy Recovery Ventilators (ERV) are used in a

horizontal discharge manner equipped with field

provided balancing damper assembly in the horizontal

duct work. A roof curb must be provided to Rooftop

Systems specifications. These wheels conserve energy by

mixing warmer air with cooler air in the following manner:

Re cov ery Wheel Mode

The Recovery Wheel mode is accomplished by two

blowers providing continuous exhaust of stale indoor air

and replacement by equal amount of outdoor air. Energy

recovery is achieved by slowly rotating the energy

recovery wheel within the cassette frame work. In winter,

the ERV adsorbs heat and moisture from the exhaust air

stream during one half of a complete rotation and gives

them back to the cold, drier intake air supply during the

other half rotation. In summer, the process is automatically

reversed. Heat and moisture are absorbed from incoming

fresh air supply and transferred to the exhaust air stream.

This process allows outdoor air ventilation rates to be

increased by factors of three or more without additional

energy penalty or increase in size of heating or air

conditioning systems.

VI - Rig ging Unit For Lift ing

1- Maximum weight of unit is — Varies per Series

{300-1200 Lbs.} (Crated)

2- Remove crating.

3- All panels must be in place for rigging.

VII - In stal la tion

1. Verify ERV is positioned and properly secured.

CAUTION

Danger of sharp metallic edges. Can cause injury.

Take care when servicing unit to avoid accidental

contact with sharp edges.

WARNING

Electric shock hazard. Can cause injury

or death. Before attempting to perform

any service or maintenance, turn the

electrical power to unit OFF at

disconnect switch(es). Unit may have

multiple power supplies.

2. Attach duct work to duct flanges on roof curb.

3. Remove ERV control access panel to connect field

wiring.

4. Route class II low voltage wire (3 conductor) from

thermostat or energy management through small

bushing in end panel of ERV. See wiring diagram.

a. Thermostat (dependent) - connect in parallel at

rooftop unit with "G", "C" and "W". Then connect

matching color at terminal 1, 2, and 3 respectively

on ERV circuit board.

b. Energy Management - provide +24 VAC to "1" and

common, 24 VAC to "2" terminals on ERV circuit

board.

c. Thermostat (dedicated) - splice into +24 vac (blue

wire) at (control circuit board) transformer

connection run wire to "R" terminal. Then run

another wire from "G" terminal to ERV (control

circuit board) terminal block #1.

5. All electrical connections must conform to any local

codes and current National Electric Codes (NEC) and

Canadian Electric Codes (CEC). Refer closely to unit

wiring diagram in unit and/or in these instructions for

proper wiring connections.

Energy recovery COMPONENT certified

to the AHRI Air-to-Air Energy Recovery

Ventilation Equipment Certification

Program in accordance with AHRI

Standard 1060-2000. Actual performance

in packaged equipment may vary.

ETL Certified per UL 1995

and CSA 22.2
