About the ERV/HRV Ventilation System

The Honeywell ERV/HRV Ventilation System provides improved indoor air quality through its high performance and efficiency.

Benefits

•Ventilation with sensible heat recovery (ERV and HRV)

•Ventilation with latent heat recovery (ERV only)

•Simplified mounting (hanging)

•Removable duct collars for easy ducting to the unit

•Intuitive balancing via two variable speed motors and a speed control

CAUTION: Electrical shock and fire hazard. Can cause personal and equipment damage.

•Before servicing or cleaning the system, always remove the power cord from the AC wall outlet.

•Wear protective clothing and safety glasses when installing ventilator and working with sheet metal.

•To reduce the hazards of electric shock or fire, do not perform any service to the system other than those stated in the operating manual instructions.

•To reduce the risk of electric shock, this ventilation system comes equipped with a 3-prong plug-in. This plug will fit in a polarized outlet only one way.

•Do not use ventilation system for outdoor application.

•Do not pull or twist power cord when disconnecting it from the ventilation system. Grasp the plug firmly, not the cord.

•Do not modify the power plug in any way; if modified, risk of electric shock, fire, or even damage to the unit may occur.

•Do not use the ventilation system for removal of flammable fumes, gases or connect directly to any appliances.

•Use a 120 VAC outlet only.

•Do not use an extension cord.

•Do not obstruct or cover the air intake or air outlet of the ventilation system.

•Do not modify, repair or disassemble this system. These tasks are to be performed by authorized serviced personnel only. Fire, electrical shock and/or bodily injury may occur if these warnings are not followed.

•To prevent injuries, do not operate the ventilation system, while servicing or maintaining. There are impeller wheels turning at a very high speed that must fully stop rotating prior to accessing the inside of the unit.

•Always assess how the operation of the ventilation system may interact with vented combustion equipment (i.e. Gas Furnace, Oil Furnace, Combustion, Appliances, etc.)

•Ensure unit is properly installed and suspended to prevent falling or dropping injuries.

Determining Your Ventilation Needs

How much fresh air do you need?

Good air quality is based in part on the capacity of the home’s ventilation system. Usually, the unit’s capacity is measured in CFM (Cubic Feet per Minute) or L/s (Liters per second) of fresh air being distributed in the living space. Use the ASHRAE 62.2 Ventilation Standard, the Room Count Calculation Method, or the Air Change Per Hour (ACH) Method to determine your ventilation needs.

ASHRAE 62.2 Ventilation Standard

ASHRAE 62.2 CFM Sizing Chart

	Floor Area (ft2)	Number of Bedrooms / CFM
		0-1	2-3	4-5	6-7	>7
	< 1500	30	45	60	75	90

ANSI/ASHRAE STANDARD 62.2-2007 - Ventilation Air Requirements; values in cfm The above chart outlines the minimum requirements for continuous ventilation.

Room Count Calculation Method

Living Space	Number of Rooms	x CFM (or L/s)	=	CFM Required
Master Bedroom		x 20 cfm (or 10 L/s)	=
Basement		x 20 cfm (or 10 L/s)	=
Single bedroom		x 10 cfm (or 5 L/s)	=
Living Room		x 10 cfm (or 5 L/s)	=
Dining Room		x 10 cfm (or 5 L/s)	=
Family Room		x 10 cfm (or 5 L/s)	=
Recreation Room		x 10 cfm (or 5 L/s)	=
Other		x 10 cfm (or 5 L/s)	=
Kitchen		x 10 cfm (or 5 L/s)	=
Bathroom		x 10 cfm (or 5 L/s)	=
Laundry Room		x 10 cfm (or 5 L/s)	=
Utility Room		x 10 cfm (or 5 L/s)	=
	Total Ventilation Requirement		=

Air Change Per Hour (ACH) Method

TOTAL cubic feet X 0.35 per hour = total cubic feet per hour Take total and divide by 60 to get cubic feet per minute (CFM) Example: A 25 ft. x 40 ft. (1,000 sq. ft.) house with basement

1,000 sq. ft. x 8 ft. high x 2 (1st floor + basement) = 16,000 cu. ft. 16,000 cu. ft. x 0.35 ACH = 5,600 cubic feet per hour

5,600 cu. ft. / 60 Minutes = 93 cubic feet per minute (CFM) 93 CFM is your ventilation need

This application uses a devoted duct system for the exhausting of stale air accumulated in the home. The fresh air is introduced into the return air duct and is distributed through the home by the existing supply air ductwork of the forced air system.

Make sure when using this application that your fresh air duct connection to the forced air system return air duct is at least 3 feet from the forced air system. You should check with your local code or the forced air system’s manufacturer.

The forced air system’s blower does not have to run when the unit is operating, but is recommended for maximum effectiveness.

NOTE: For the minimum distance between the fresh air connection and the forced air system, check with your local building codes and forced air system manufacturer.

NOTE: For dwellings with multiple forced air systems, Honeywell recommends one ERV/HRV unit per system.

NOTE: Refer to the Wiring section (beginning on page 18) for instructions to connect the unit to operate the forced air system with the ERV/HRV unit.

Installation Steps

1Installation Kit

Ensure that you have all of the following installation items:

4 Duct Collars	Installation Kit:
	• 2 Flexible 6 in. Vinyl Ducts
	• 1 Condensation Drain Line (10 in.)
	• 1 Drain Adapter with Nut
	• 4	Tie Wraps (30 in.)
	• 16 Hex-head screws (1/4 x 5/8 in.)
	• 4	Hex-head screws (1/4 x 1 in.)
	• 4	Washers
	• 1	Drain cap (VNT5250E100 and VNT5200E1000 only)
	• 1 power cord, 120 Vac (not shown)

2Installation Area

The ERV/HRV unit should be installed in a mechanical room or as close to an outside wall as possible.

The ERV/HRV unit must always be installed in an area where the air is conditioned to avoid freezing the condensate line.

The contractor should install the unit in an area that allows the homeowner easy access for maintenance. It is very important to install an electric receptacle (120 Vac) near the unit, a separate circuit breaker

is also recommended. It is best to have access to a condensate drain near the ERV/HRV unit to avoid having to use a condensate pump.

NOTE: Installation is not recommended in unconditioned areas such as an attic or crawl space where the temperature can fall below 32 ºF (0 ºC).

NOTE: Ducting in unconditioned areas must be fully sealed and insulated.

Installation Steps (continued)

3Hanging the ERV/HRV

The ERV/HRV unit enables you to save time and effort by offering a simplified hanging system.

TIP: Removing the core unit makes installation easier since the unit weighs less without the core inside.

1.Attach straps to joist using the supplied washers and four 1 in. hex-head hanging screws.

2.Pull on middle of strap while gently lifting unit upward to raise the unit.

3. Make final adjustments to ensure that the HRV/ERV is level.

NOTE: If the unit is not level, improper drainage will occur and could lead to moisture and leakage problems.

Installation Steps (continued)

4Installing the flex duct to the ERV/HRV

TIP: Honeywell recommends using approximately 16 inches of flexible duct (supplied in kit) between the unit and the rigid duct for noise dampening. The flex duct is mounted to the unit the same way as the insulated flex.

1.Insert the vinyl duct over the hooks on the duct collar and seal with a supplied 30 inch tie wrap.

3. Finish by taping the duct on the collar.

5.Secure collar with the supplied 5/8 in. hex-head screws.

2.Insert insulation inside the outer ring of the duct collar.

4. Slide collar onto unit.

IMPORTANT: Always fix and secure each collar using four of the 5/8 in. screws supplied. This step is critical in order to prevent condensation accumulation.

TIP: Attach the flex duct to the collar first, and then attach the collar to the unit.

Installation Steps (continued)

5Installing the condensation drain line

Insert the threaded drain adapter through the bottom of the unit and hand tighten the plastic nut supplied with the drain kit.

Use a wrench to tighten the nut another half turn to ensure a complete seal.

Install the condensate tubing by pushing the clear plastic tubing over the drain adapter.

Make a condensate trap by looping the clear plastic tubing. This loop will prevent foul odors from entering the unit.

Use a condensate pump if you don’t have access to the floor drain.

Drainless Application

NOTE: If installing an ERV unit (VNT5150E1000 or VNT5200E1000) in a region where the outdoor temperature does not drop below freezing, the condensate drain line does not need to be installed and the unit may be installed as a drainless application.

1.Insert the threaded drain adapter through the bottom of the ERV with the drain connection inside of the unit as shown in the figure.

2.Fit the rubber washer over the drain adapter and then attach the plastic nut.

3.Hand tighten the plastic nut supplied with the drain kit.

4.Use a wrench to tighten the nut another half turn to ensure a complete seal.

5.Attach the drain cap to the drain adapter inside the unit.

6Connecting the power cord

ERV/HRV Power Cord

Insert the power cord on top of the unit. Press firmly to make sure the power cord is secure.

IMPORTANT: Do not plug the power cord into the wall receptacle at this time.

Electric Wall Outlet

Honeywell recommends that the unit has a dedicated receptacle with 120 VAC.

Avoid connecting the unit to the wall receptacle with an extension cord.

Honeywell does not recommend the use of an extension cord. Ensure that the receptacle’s polarization is correct.

NOTE: If the LED light on the ERV/HRV control panel remains green, the motors do not energize, and the controls do not operate; this can indicate that the polarization in the main AC outlet is inverted.

IMPORTANT: Always consult a qualified technician to ensure proper installation of main power.

7Installing outside hoods for the fresh air and the exhaust

Locate the outside hoods at least 18 inches (0.46 m) above grade and at least 72 inches (1.83 m) apart.

NOTE: Do not locate the fresh air vent	72 (1,829)
hood close to known sources of
pollutants such as dryer vents.

Automated Defrost

The ERV and HRV units are equipped with an automatic defrost feature to eliminate any ice build up on the core.

•Automatic defrost is initiated once every hour when the fresh air supply temperature drops to 23°F (-5°C) or colder.

•The defrost cycle operates by turning off the supply fan while continuing to operate the exhaust fan.

•The exhaust fan speed is adjusted proportionally based on the outdoor temperature, initially operating at low speed.

•As the outdoor temperature continues to drop, the exhaust fan speed will increase, and will operate at maximum speed when the outdoor temperature is -4°F (-20°C) or less.

•Defrost cycle runs for 4 minutes with the supply fan off, followed by 40 minutes of continuous normal operation.

•Defrost cycles will continue to repeat as long as the temperature is 23°F (-5°C) or less.
