2.2 UNIT DOOR(S)

The ERV140 ECM and HRV160 ECM units have one front door and one back door while the HRV160 unit has one door. For this last model, the unit door can be relocated on the back of the unit. This can be helpful to optimize duct configuration while keeping access for unit maintenance. To change door location, follow these steps:

A. Remove both door lower mechanical screws no. 8-32 x 1” (1) and set

aside.

B. Open (2) and lift out the door (3). To remove unit back panel, repeat steps A and B, but instead of removing

2 mechanical screws, there are 4 mechanical screws to be removed. Hang the door to the back of the unit and secure it by tightening its both lower mechanical screws. Hang back panel to the front of the unit and secure it by tightening its four metal screws.

2. INSTALLATION (CONT'D)

2.3 LOCATING THE UNIT

Choose an appropriate location for the unit.

• Within an area of the house where the ambient temperature is kept between 50°F and 160°F.

• Away from living areas (dining room, living room, bedroom), if possible.

• So as to provide easy access to the interior of the unit, for semi-annual and annual maintenance.

• Close to an exterior wall, so as to limit the length of the insulated flexible duct to and from the unit.

• Away from hot chimneys and other fire hazards.

• Allow for a power source (standard 3-prong grounding outlet).

• Close to a drain. If no drain is close by, use a pail to collect run-off.

Hang the unit with the four chains and springs provided. See illustration at right.

CAUTION

Make sure the unit is level.

2.4 PLANNING OF THE DUCTWORK

• Keep it simple. Plan for a minimum of bends and joints.

• Keep the length of insulated ducts to a minimum.

• Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the exhaust air from a dryer or a range hood. This would cause clogging of the filters and recovery module.

• If the house has two floors or more, be sure to plan for at least one exhaust register on the highest lived-in level.

VD0205

2.5 CALCULATING DUCT SIZE

Use the table below to ensure that the ducts you intend to install will be carrying air flows at or under the recommended values. Avoid installing ducts that will have to carry air flows near the maximum values and never install a duct if its air flow exceeds the maximum value.

DUCT DIAMETER RECOMMENDED AIR FLOW MAXIMUM AIR FLOW

4” Ø 40 CFM (19 L/S) 60 CFM (28 L/S) 5” Ø 75 6” Ø 120

EXAMPLE OF CALCULATION Problem: My installation requires two exhaust registers (one for the kitchen, and the other for

the bathroom). I will connect these registers to a main duct which will connect to the unit (high speed performance value of 140 cfm). What size of duct should I use for the main exhaust duct and for both end branches leading to the registers? (See illustration at right.)

Solution: Simplified method. (For a more detailed method of calculating duct size, refer to the

ASHRAE or HRAI HANDBOOK.)

Main duct: Table indicates for a 6” Ø duct: recommended air flow: 120 cfm, maximum air flow:

180 cfm. The 140 cfm high speed air flow is close enough to the recommended value (120) and far away enough from the maximum value (180). Therefore, a 6” Ø duct or larger is an appropriate choice for the main exhaust duct.

End branches: Each end branch will have to transport a 70 cfm air flow (140 divided by 2). Table

indicates for a 5” Ø duct: recommended air flow: 75 cfm; maximum air flow: 110 cfm. The high speed air flow of 70 cfm is close enough to the recommended value (75) and far away enough from the maximum value (110). Therefore, a 5” Ø duct or larger is an appropriate choice for both end branches.

NOTE: A 4” Ø duct would have been too small because the maximum acceptable value for a 4” Ø duct is 60 cfm.

2.6 INSTALLING THE DUCTWORK AND REGISTERS

2.6.1 FULLY DUCTED SYSTEM

Stale air exhaust ductwork

Never install a stale air exhaust register in a closed room where a combustion device operates, such as a gas furnace, a gas water heater or a fireplace.

Stale air exhaust ductwork

• Install the stale air exhaust registers where the contaminants are

produced: kitchen, living room, etc. Position the registers as far from the stairway as possible and in such a way that the air circulates in all the lived-in spaces in the house.

• If a register is installed in the kitchen, it must be located at least

4 feet from the range.

• Install the registers 6 to 12 inches from the ceiling on an interior wall

OR install them in the ceiling.

• If possible, measure the velocity of the air flowing through the

registers. If the velocity is higher than 400 ft/min, then the register type is too small. Replace with a larger one.

Fresh air distribution ductwork

• Install the fresh air distribution registers in bedrooms, dining rooms,

living room and basement.

• Keep in mind that the fresh air registers must be located as far as

possible from the stale air registers.

• Install the registers either in the ceiling or high on the walls with air flow directed towards the ceiling. (The cooler air will then cross

the upper part of the room and mix with room air, before descending to occupant’s level.)

• If a register must be floor installed, direct the airflow up the wall.

2.7 CONNECTING THE DUCTS TO THE UNIT

NOTE: All unit ports are were created to be connected to ducts having a minimum of 6” diameter, but if need be, they can be connected

to bigger sized ducts by using an appropriate transition (e.g.: 6” diameter to 7” diameter transition).

Insulated flexible ducts Use the following procedure to connect the insulated flexible ducts to the ports of the unit (Exhaust air to outside and Fresh air from

outside ports).

CAUTION

If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts.

1. Pull back the insulation to expose the flexible duct.

2. Attach the flexible duct to the port using tie wrap.

3. Pull the insulation over the joint and tuck in between the inner and outer rings of the double collar.

4. Pull down the vapor barrier (shaded part in illustrations below) over the outer ring to cover it completely. Fasten in place the vapor

barrier using the port strap (included in unit parts bag). To do so, insert one collar pin through vapor barrier and first strap hole, then insert the other collar pin through vapor barrier and center strap hole and close the loop by inserting the first collar pin in the last strap hole.

CAUTION

Make sure the vapor barrier on the insulated ducts does not tear during installation to avoid condensation within the ducts.

3.5 ELECTRICAL CONNECTION TO MAIN CONTROL

For more convenience, these units can also be controlled using an optional main wall control. NOTES: 1. The integrated control must be turned OFF to use an optional main control.

2. If an optional auxiliary control is used, if activated, this auxiliary control will override the optional main control.

WARNING

Always disconnect the unit before making any connections. Failure in disconnecting power could result in electrical shock or damage of the wall control or electronic module inside the unit.

CAUTION

Never install more than one optional main wall control per unit. Make sure that the wires do not short-circuit between themselves or by touching any other components on the wall control. Avoid poor wiring connections. To reduce electrical interference (noise) potential, do not run wall control wiring next to control contactors or near light dimming circuits, electrical motors, dwelling/building power or lighting wiring, or power distribution panel.

Use the terminal connector included in the installation kit to perform the electrical connection for main and optional wall controls. Check if all wires are correctly inserted in their corresponding holes in the terminal block. (A wire is correctly inserted when its orange receptacle is lower than another one without wire. On picture at right, wire A is correctly inserted, but wire B is not.)

4. ELECTRICAL CONNECTION TO THE FURNACE/AHU

WARNING

Never connect a 120-volt AC circuit to the terminals of the furnace/AHU interlock (standard wiring). Only use the low voltage class 2 circuit of the furnace/AHU blower control.

For a furnace/AHU connected to a cooling system:

On some older thermostats, energizing the “R” and “G” terminals at the furnace/AHU has the effect of energizing “Y” at the thermostat and thereby turning on the cooling system. If you identify this type of thermostat, you must use the ALTERNATE FURNACE/AHU INTERLOCK WIRING.
