Installation Steps. Honeywell VNT5200E1000, VNT5070E1000, VNT5150H1000, VNT5150E1000, VNT5070H1000, VNT5200H1000, VNT6150H1000

Installation Steps

1 Installation Kit

Ensure that you have all of the following installation items:

4 Round Duct Collars (VNT5150, VNT5200,

VNT6150 & VNT6200)

Installation Kit:

• 2 Flexible 6 in. Vinyl Ducts (VNT5150, VNT5200,

VNT6150, VNT6200)

• 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 (VNT5070E1000, VNT5150E1000 and

VNT5200E1000 only)

• 1 power cord, 120 Vac (not shown)

4 Oval Duct Collars (VNT5070)

2 Installation 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.

3a Hanging the VNT5150, VNT5200, VNT6150 or VNT6200

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.

3b Mounting the VNT5070

1. Fix the control module bracket to the top of the

VNT5070 using the supplied mounting screws.

2. Slide the control module onto the bracket

using the key holes.

3. Fix the wall mount bracket to two 2x4s or to

a precut sheet of plywood using the supplied

mounting screws.

4. Hang the unit on the bracket.

5. Secure with two sheet metal screws.

NOTE: When these mounting steps are complete, resume normal installation procedures beginning on page 20, “Installing the flex duct to the ERV/HRV.”

Installation Steps (continued)

4 Installing the flex duct to the ERV/HRV

TIP: Honeywell recommends using approximately 16 inches of flexible duct (supplied in kit with VNT5150,

VNT5200, VNT6150 and VNT6200) 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.

2. Insert insulation inside the outer ring of the duct

collar.

3. Finish by taping the duct on the collar.

TIP: For the VNT5070 unit, balancing should be done before taping the insulation onto the collar. See balancing steps on page 30.

4a. Slide collar onto unit (VNT5150, VNT5200,

VNT6150 and VNT6200)

20

4b. Attach collar onto unit (VNT5070)

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.

5. Secure collar with the supplied 5/8 in.

hex-head screws.

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

5 Installing 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, VNT5200E1000, VNT5070E1000) 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.

Connecting 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.

7a Installing 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 hood close to known sources of pollutants such as dryer vents.

IMPORTANT: Always consult your local code for spacing requirements in your area.

Installation Steps (continued)

7b Optional Matrix hood (50063805-009) installation for fresh air and exhaust air

NOTE: Only for applications up to 115 CFM maximum speed. Higher airflow rates are limited by higher static pressures and the potential of cross-contamination between the supply and exhaust air streams. The Matrix hood design is suitable for smaller spaces commonly found in town homes and condominiums which require less airflow rates.

NOTE: A 6 in. to 5 in. reducer is required if you are installing the matrix hood (50063805-009) with the

VNT5070.

See Matrix hood literature for step-by-step instructions.
