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

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

down discharge manner equipped with field provided

balancing damper assembly through the roof. 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.

4. Remove barometric exhaust hood from door marked

filter access. Install barometric exhaust hood over

exhaust blower outlet.

5. Duct work should be installed into roof curb before

installing ERV on curb.

6. Roof curb gasket must be applied to all top surfaces of

the curb.

7. Forklift channels must be removed from the base of

ERV before setting unit on curb. See Figure 1.

8. Position unit on roof curb and provide service access

to ERV control access door and wheel.

CAUTION

Danger of sharp metallic edges. Can cause injury.

Take care when servicing unit to avoid accidental

contact with sharp edges.
