ERV / HRV
INTRODUCTION
The Energy/Heat Recovery Ventilator (ERV/HRV) is used to exchange indoor stale air with outside fresh air. The unit is equipped with a special energy/heat recovery core which transfers both sensible and/or latent heat between the fresh incoming air and stale exhaust air. The cross-flow design core allows entering and leaving air streams to transfer heat and/or latent energy without mixing (See Fig. 3).

UNIT INSTALLATION
!CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Do not install ERV/HRV in a corrosive or contaminated atmosphere.
Mount Unit
The ERV/HRV can be suspended from floor joists using chains and 4 springs. Attach metal hanging bracket to all 4 sides of cabinet. (See Fig. 6.) The unit may be installed on a shelf if an isolation pad is provided to dampen vibration. Unit should always be installed as level as possible.
A05331
Fig. 6 - Chain Spring Installation
Independent System Application
In the absence of a forced-air system and a typical duct system layout, the ERV/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.
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. (152 to 305mm) from the ceiling on an interior wall and airflow directed toward ceiling. If registers are floor installed, airflow should be directed toward the wall.
!WARNING
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.
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 (122m) per 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.
Forced-Air Application
Most ERV/HRV applications will be installed in conjunction with new or existing forced-air system. To operate properly, the fresh-air supply and stale-air return from ERV/HRV connect directly to return-air duct system. This is how the ERV/HRV distributes fresh air and removes stale air from inside of building (See Fig. 7). For these installations, furnace or fan coil blower must be interlocked and operate continuously whenever ERV/HRV is energized. See Fig. 17 for interlock wiring detail.
NOTE: The fresh air from ERV/HRV is introduced into return-air duct at a point no less than 6 ft (1.8m) upstream of furnace or fan coil. This connection should be direct (See Fig. 7). This is to allow incoming fresh-air to mix before entering indoor equipment.

!CAUTION
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in minor property damage from sweating duct or loss of unit efficiency and capacity.
If ERV/HRV duct work is installed in an unconditioned space, insulated flexible duct is required.
Insulated flexible duct is required on both fresh-air inlet and exhaust-air outlet ducts connecting to exterior wall. When using insulated flexible duct, the vapor barrier of the flexible ducts must be taped very tight to prevent condensation problems. To reduce pressure drop, stretch the flex duct and support it in a proper manner to avoid reduced airflow.
When connecting the ERV/HRV to a return-air duct system, insulated flexible duct can be used. However, when metal or rigid ducts are applied use approximately 18-in. (457mm) of flexible duct at ERV/HRV ports for fresh-air supply, and stale-air return. When using metal duct from fresh-air supply to system duct work, the metal duct should be insulated. (See Fig. 8.) This can act as a silencer when connecting ducts to return-air duct system. This should eliminate transmission of noise or vibration from unit to main duct system.

Locate and Install Exterior Hoods
IMPORTANT: To prevent condensation problems, insulated flexible ducts are required on both fresh-air inlet and exhaust-air outlet ducts connecting between ERV/HRV and exterior wall.
Fresh-air intake and stale-air exhaust must be separated by at least 6 ft (1.8m). Fresh-air intake must be positioned at least 10 ft (3m) from nearest dryer vent, furnace exhaust, driveway, gas meter, or oil fill pipe. Fresh-air intake must be positioned as far as possible from garbage containers and potential chemical fumes. When possible, it is advised to locate the intake and exhaust hoods on same side of house or building. The intake and exhaust hoods should never be located on interior corners or in dead air pockets (See Fig. 7). Both intake and exhaust hoods must be 18-in. (457mm) from ground and at least 12-in. (305mm) above anticipated snow level.
After selecting proper hood locations, make appropriate size hole through exterior wall, pass flexible duct through hole and insert hood tube into duct. Tape duct vapor barrier tightly around hood tube and insert assembly back into wall and fasten securely.
Condensate Drain
(For ERV, skip this step and continue to the next step.)
To connect condensate drain, proceed as follows:
1.Punch out holes in foam insulation and door, then insert sleeved grommets into bottom of unit using the gasket washer and nut. (See Fig. 9.)
2.Cut two sections of plastic tubing, about 12-in. / 305mm long and attach them to each drain.
3.Join the two short sections of plastic tubing to the “T” connector and the main tube as shown.
4.Make a loop in the tubing below the “T” connector to create a trap to prevent sewer gases from entering the ventilation system. (See Fig. 9.)
5.Connect unit drain to building’s main drain. Provide slight slope from unit for run-off.

Fig. 10 - Typical Wall Control
Operation
The Standard and Latent wall controls have 4 basic modes of operation, OFF, LOW, HIGH, and INTERMITTENT. Be sure that all modes of operation are fully functional. See Table 1 indicating standard control operation.
1.With switch off, ERV/HRV is inoperative and the LED is out.
2.With switch on LOW, ERV/HRV continuously exchanges air with outside. If control is satisfied, blower will run in low speed, otherwise, blower will run on high speed. The LED is illuminated all the time.
3.With switch on INTERMITTENT, the ERV/HRV exchanges air with outside on high-speed blower, and unit shuts down when control is satisfied. The ON LED is illuminated all the time, and AIR EXCHANGE LED is illuminated only when unit is running.
Humidity Selector
The humidity selector is a built-in control designed to properly control the level of humidity in the house during the winter and summer months. This control helps avoid condensation problems in upper northern regions where indoor humidity is a problem during the winter season.
NOTE: This control is not to be confused with a dehumidistat used during the summer months to control high relative indoor humidity.
Table 2 recommends humidity levels to avoid condensation.
