NOTE: Read the entire instruction manual before starting the

installation.

SAFETY CONSIDERATIONS

Installation and servicing of this equipment can be hazardous due

to mechanical and electrical components. Only trained and

qualified personnel should install, repair, or service this equipment.

Untrained personnel can perform basic maintenance functions such

as cleaning and replacing air filters. All other operations must be

performed by trained service personnel. When working on this

equipment, observe precautions in the literature, on tags, and on

labels attached to or shipped with the unit and other safety

precautions that may apply.

Follow all safety codes. Installation must be in compliance with

local and national building codes. Wear safety glasses, protective

clothing, and work gloves. Have fire extinguisher available. Read

these instructions thoroughly and follow all warnings or cautions

included in literature and attached to the unit.

Recognize safety information. This is the safety-alert symbol z_.

When you see this symbol on the unit and in instructions or

manuals, be alert to the potential for personal injury. Understand

these signal words; DANGER. WARNING, and CAUTION. These

words are used with the safety-alert symbol. DANGER identifies

the most serious hazards which will result in severe personal injury

or death. WARNING signifies hazards which could result in

personal injury or death. CAUTION is used to identify unsafe

practices which may result in minor personal injury or product and

property damage. NOTE is used to highlight suggestions which

will result in enhanced installation, reliability, or operation.

INTRODUCTION

The ERVCCLHA Energy Recovery Ventilator is used to exchange

indoor stale air with outside fresh air. The unit is equipped with a

special energy recovery core which transfers both sensible and

latent heat between the fresh incoming air. The cross-flow design

core allows entering and leaving air streams to transfer heat energy

without mixing. (See Fig. 2.)

The ERVCCLHA is available in 2 sizes with airflow ranges of

60-148 CFM (28 - 71 L/s), and 60-183 CFM (28 - 89 L/s). The

design of this unit is horizontal. Special attention should be given

to duct application, balancing the ERV. and locating unit for easy

access and routine maintenance.

INSTALLATION CONSIDERATIONS

Inspect Equipment

Move carton to final installation location. Remove ERVCCLHA

from carton taking care not to damage unit. Remove all packaging

and inspect unit for damage. Remove parts bag from inside unit.

File claim with shipping company if shipment is damaged or

incomplete. Check to make sure ERV unit matches Fig.1.

Select Location

The ERV should be located in a conditioned space and in close

proximity to a fused power source. It should be easily accessible

for routine maintenance.

If ERV is installed independent of a forced-air system, unit should

be located near the center of the air distribution system. If ERV is

installed in conjunction with a forced-air system, unit should be

located next to (or close to) the indoor equipment.

Independent STALE A_R TO OUTSIDE System Application In tire absence of a forced-air system and a typical duct system layout, the ERV can be applied as an independent or stand alone unit. To ensure comfort, this type of application involves running both fresh-air throughout and return-air registers (or stale-air pickup registers) the home. Fresh-air registers are normally located in bedrooms, dining rooms, living rooms, and basements.
