SAFETY CONSIDERATIONS

Installation and servicing of this equipment can be hazardous due
to mechanical and electrical components. Only trained and quali-
fied 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 and work
gloves. Have fire extinguisher available during start-up and
adjustment procedures and service calls.
Recognize safety information. This is the safety-alert symbol
When you see this symbol on the furnace and in instructions or
manuals, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, and CAU-
TION. These words are used with the safety-alert symbol. DAN-
GER identifies the most serious hazards which will result in severe
personal injury or death. WARNING signifies a hazard which
could result in personal injury or death. CAUTION is used to
identify unsafe practices which would 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 Heat Recovery Ventilator (HRV) is used to exchange indoor
stale air with outside fresh air. The HRV unit is equipped with a
special heat recovery core which transfers sensible heat between
the fresh incoming air and stale exhaust air.
It is recommended, but not required to locate the HRV in a
conditioned space. Special attention should be given to condensate
drain, duct application, balancing HRV, and locating unit for easy
access and routine maintenance.
The cross-flow design core allows entering and leaving air streams
to transfer heat energy without mixing (See Fig. 15, and 18
through 25).

LOCATION

I. INSPECT EQUIPMENT
Move carton to final installation location. Remove HRV 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 incom-
plete. Check to make sure HRV unit matches Fig. 1 through 3 and
7 through 9.
II. SELECT LOCATION
The HRV 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 HRV is installed independent of a forced-air system, unit should
be located near the center of the air distribution system. If HRV is
installed in conjunction with a forced-air system, unit should be
located next to (or close to) the indoor equipment.
CAUTION: UNIT DAMAGE HAZARD
Failure to follow this caution may result in reduced life of
this unit.
Do not install HRV in a corrosive or contaminated
atmosphere.
I. MOUNT UNIT
The HRV can be suspended from floor joists using chains and 4
springs. Attach metal hanging bracket to all 4 sides of cabinet (See
Fig. 4). Unit should always be installed as level as possible.

II. INDEPENDENT SYSTEM APPLICATION
In the absence of a forced-air system and a typical duct system
layout, the HRV can be applied as an independent or stand alone
unit. To ensure comfort, this type of application involves running
both fresh-air and return-air registers (or stale-air pickup registers)
throughout the home.
CAUTION: CARBON MONOXIDE POISONING
HAZARD
Failure to follow this warning could result in personal
injury or death.
Do not install return-air registers (or stale-air pickup
registers) in same room as gas furnace or water heater.
Fresh-air registers are normally located in bedrooms, dining room,
living room, and basement. It is recommended that registers be
placed 6 to 12 in. from the ceiling on an interior wall and airflow
directed toward ceiling. If registers are floor installed, airflow
should be directed toward the wall.
Return-air (or stale-air pickup registers) are normally located to
draw from kitchen, bathroom, basement, or other rooms where
stale-air can exist.
Proper size and type of registers must be used to minimize pressure
drop. The velocity of airflow through register should not be above
400 ft/minute.
Maximum length of duct for the system should be designed
according to the highest speed of the unit. Refer to specifications
listed in unit Product Data Digest for ventilation capacities.
