2. Installation

2.1 Inspection

Inspect the exterior of the unit for shipping damage by ensuring that there is no damage to the door, door latches, door hinges, damper, duct collars, cabinet, etc. Inspect the interior of the unit for damage by ensuring that the fan motors and housings, heat or energy recovery cores, insulation, dampers, actuators and drain pans are all intact.

If transportation damage is found, file a claim immediately with the transportation agency. Remove all packaging, tape, etc. from the cabinet.

2.2 Mounting Location Requirements

When determining an installation location, the unit must be mounted in a heated area to prevent condensate drain lines from freezing. The mounting location should be away from occupied areas to provide quiet operation. The area should also be easily accessible for maintenance.

NOTE:

These units have minimum clearance requirements when mounting. See Appendix B for specific clearance requirements. Mounting options must allow 12” clearance in front of control cover for access.

A mounting location close to an exterior partition will minimize the length of insulated duct. The unit should be close to a drain and 120 volt, 60 Hz power supply. The unit should be mounted away from hot chimneys, electrical panels and other hazards.

! WARNING

It is recommended to wear safety glasses and gloves while performing these instructions.

2.3 Mounting Options

There are several options for hanging or floor mounting the unit.

NOTE:

In all cases, the unit must be level. Consult local building code for restrictions in your area regarding installation.

Hang the unit with the reinforced rubber straps provided as shown in Appendix A. Check with local building codes regarding the use of rubber straps in commercial buildings. Attach the straps to the unit with two no. 8 screws provided. Then attach the other end of the strap to the ceiling joists, trusses, custom frame, etc.

The unit can also be hung with 3/8” threaded rod and U channels or angles (not supplied) as shown in Appendix A.

When installing the unit, keep in mind that access to the control panel may be required. Supply and exhaust ducts to outdoors may have 1” to 2” of insulation on them. Rubber vibration isolation may be required and is recommended for quiet operation.

The unit can also be mounted on a metal or wooden curb (not supplied) bolted to the floor as shown in Appendix A. Space must be left under the unit to allow connection of drain lines. A gradual slope is required for the condensate water to drain by gravity (minimum 1/4”/foot). If this is not possible, a pump should be used. If attachment of the unit to the curb is required, ensure that screws, bolts and mounting hardware do not interfere with moving parts or that the integrity of the cabinet insulation is not affected.

2.4 Ductwork

The supply and exhaust duct connections on the unit are as follows:

UNIT

DUCT SIZE

 

 

B6LC, B12LC

14” x 8” (356 mm x 203 mm)

 

 

B1600705

20” x 8” (508 mm x 203 mm)

 

 

NOTE:

Duct sizes are for connection purposes only. Ducts should be sized to keep noise and pressure drop to a minimum.

The supply and exhaust ducts connected to outdoors, as well as any ducts passing through an unconditioned space, must have a minimum insulation value of R5. In addition, a continuous integral vapor barrier over the duct insulation must be used.

Air balancing dampers are recommended for both supply and exhaust ducts to allow for adjustment of airflow.Also, flexible canvas connectors should be installed close to the unit in the supply duct to the building and the exhaust duct from the building to reduce noise transmission from the unit to the building, see Appendix C.

All ports on the B6LC and B12LC units have 1” flanges to facilitate the installation of the ductwork. Please note that the “Fresh Air from Outdoors” port has a defrost damper incorporated with it.

Ensure that any mechanical fasteners used to connect the duct do not interfere with the operation of the damper. Screws can be installed on the side of the cabinet rather than the flange for this port only. For port locations see Appendix B.

All ports on the B1600705 unit have 2” flanges to facilitate the installation of the ductwork. Please note the “Fresh Air From Outdoors” connection is factory set to be the left side upper port. It is possible to reverse the operation of the defrost damper in order to use the port on top of the cabinet for “Fresh Air From Outdoors” connection.

To change the «Fresh Air From Outdoors» from the side to the top use the following directions. For port locations see Appendix B.

Remove the cover of the damper motor with a flat screwdriver. Reverse the ORANGE and RED wires by moving the ORANGE from terminal no. 2 to terminal no. 3 and moving the RED wire from terminal no. 3 to terminal no. 2. The end result in order to have the “Fresh Air From Outdoors” connection to the top port will be: no. 1 - WHITE, no. 2 - RED, no. 3 - ORANGE.

2.5 Internal Grilles and Diffusers

Locate exhaust grilles and supply diffusers to provide effective ventilation and avoid short circuiting of airflows.Adjustable dampers should be provided at every grille and diffuser location to make balancing of the system possible.

A proper selection of style and size of grilles and diffusers is required to minimize pressure drop. The velocity of the airflow should not exceed 400 ft./min. for normal applications.

The duct system should be designed according to the high speed flow rate of the unit. In order to keep the noise and pressure drop to a minimum, a maximum air velocity of 1100 ft/min. should be used in calculations in duct design. The duct runs should be kept as short as possible with the minimum amount of elbows and transitions.

The manufacturer recommends the use of smooth radius elbows or square elbows with turning vanes to achieve maximum performance.

2.6 Exterior Hoods

It is important that the fresh air intake hood be positioned well away from any source of contamination. The exterior supply and exhaust hoods must be separated enough to prevent cross-contamination and at an elevation that will prevent blockage by snow, dirt and leaves.

NOTE:

Consult local building code for restrictions in your area.

A rodent screen with 1/4” mesh must be installed to prevent the intake of large debris and animals. A backdraft damper may need to be installed in the exhaust duct to prevent cold air entering the building if the unit is to be shut off for a long period of time.

To maintain optimum airflow performance, exterior hood selection must be such that the minimum free area of opening is 140 inches2.

2.7 Drains

The drain fittings provided with the unit will accept a 3/4” NPT coupler (supplied by others). The drain line for the unit must be fabricated on-site and connected to the building main. A loop in the hose or trap in the copper or plastic pipe must be provided to prevent sewer gases from entering the unit when connecting to a drain as illustrated in Appendix D.

NOTE:

Consult local building code for plumbing requirements in your area. If copper pipe is to be used, ensure not to solder to the 3/4” coupler while it is attached to the plastic drain fitting as deformation may occur. Ensure adequate slope is present to allow good drainage (minimum 1/4” per foot).

2.8 Electrical Connections

3.1 General Information

FAN INTERLOCK RELAY OUTPUT (FF)

External fan control can be achieved by connecting an external 24 volts fan control through dry contacts (FF). These contacts are closed on a call for ventilation or defrost. See wiring diagram shown in Appendix E.

SPEED SELECTION (6LC /12LC UNITS ONLY)

There are three speed settings available with the controls, only two of which can be functional at any one time. The units are factory set to use the low and high speed taps on the blower motors. If necessary, the medium speed tap can be used instead of the low speed tap. See wiring diagrams for instructions on how to make this change. Units without the remote wall control option can be shut off by opening the contact between LOW - COM or HIGH - COM as shown in Appendix E-2.

3.2 Sequence of Operation

Before start-up, check the unit for obstructive packaging, objects near or in blowers, dampers, heat exchangers, etc. Once installation is complete, check all modes of operation to ensure that the unit is working properly. Close the doors and check for operation on LOW, COM and HIGH. Use a wall control or the dry contact switching to run fan speeds as shown in Appendix E-2.

The B1600705 unit is two speed. Low speed can be initiated by creating a closure across LOW - COM or high speed can be initiated by creating a closure across HIGH - COM.

UNIT CHECK POINTS (ALL UNITS):

Power connected, no ventilation call - Both fans are off, defrost damper (if equipped) closes off fresh air from outdoors.

Power connected, low speed call - Both fans on low speed internal defrost damper (if equipped) opens fresh air from outdoors. For B6LC and B12LC units only, if equipped with recirculation module, the internal defrost damper closes recirculation opening.

Power connected, high speed call - Both fans on high speed, defrost damper opens fresh air from outside. For B6LC and B12LC units only, if equipped with recirculation module, the internal defrost damper closes recirculation opening.

Power connected, occupied timer/sensor connection open (unoccupied mode) - Both fans are off, defrost damper closes freshairfromoutdoors.ForB6LCandB12LCunitsonly,ifequipped with recirculation module, the internal defrost damper opens recirculation opening.

3. Controls (cont’d)

3.3 Defrost

The unit functions are controlled by integrated controls in the unit which may include Exhaust Only Defrost or Recirculation Defrost (via the recirculation module - B6LC and B12LC units only). In cold temperatures, defrost cycles will remove frost from the recovery cores to maintain good operation.

EXHAUST ONLY DEFROST (OPTIONAL)

Frost removal occurs when the supply blower de-energizes, the supply air damper and the core damper close and the exhaust fan continues to circulate only warm inside air through the heat recovery core to maintain ventilation. This process prevents the build up of ice in the core. Defrost is temperature initiated at 23°F to -22°F and time based.

! WARNING

A negative building pressure may develop during the defrost cycle with possible backdrafting fumes from combustion equipment.

RECIRCULATION DEFROST MODULE

(OPTIONAL - FACTORY INSTALLED)

The Recirculation Defrost Module is only available with the B6LC and B12LC units. The defrost cycle is electronically controlled in response to the outdoors temperature 23°F to -22°F. On a call for defrost, the supply air damper in the recirculation module closes, exhaust fan is de-energized and the supply fan continues to recirculate warm air through the heat recovery core or energy recovery core. It is possible to extend the defrost times during very cold weather by removing the jumper JU1-F on the circuit board as shown in Appendix F. For dimension and weight changes to the B6LC and B12LC models with recirculation defrost, see Appendix B-2 and B-4.

3.4 Remote Wall Control (Optional)

Remote mounted wall control options can be used to control the ventilators from a location remote to the installed unit location. The connection from the ventilator to the control is low voltage and requires a 4 conductor (24 ga. minimum) LVT cable. Models are available with a dehumidistat control. The following two options are available.

SLIDE SWITCH TYPE

Dehumidistat to engage high speed exchange.Slide switch operation supporting continuous low exchange and continuous high exchange.

VT10W (FOR B1600705 UNIT ONLY)

Ideal for pool dehumidification. Dehumidistat to engage high speed exchange. Push-button operation supporting: intermittent (stand-by) ventilation, continuous low exchange, continuous high exchange, maintenance indicator light and exchange indicator light.

4. Airflow Measurement and Balancing

Once installation is complete, the supply and exhaust airflows should be balanced. This will ensure proper operation and a good quality installation.

A well designed duct system with properly sized duct runs and equal staticpressurelossesofboththesupplyandexhaustwillaidinbalancing the unit. However, it will be necessary to take flow measurements with the proper equipment to ensure a balanced system.

Before proceeding with balancing, all windows, overhead doors and walk-in doors should be closed and exhaust systems should be turned off.

5.Maintenance and Service

5.1Bi-Monthly Maintenance

! WARNING

Disconnect power before maintaining unit.

Bi-monthly maintenance should include:

AIR FILTERS

The standard foam filters are washable. Under normal conditions it is recommended that they be cleaned every two months. More frequent cleaning may be required under extremely dirty operating conditions. Use a vacuum cleaner to remove the heaviest portion of accumulated dirt, then wash with warm water.

A medium efficiency filter for the supply air stream is available from your supplier. This filter is disposable and should be replaced when it becomes dirty.

5. Maintenance and Service (cont’d)

! WARNING

Disconnect power before maintaining unit.

5.2 Annual Maintenance

Annual maintenance should include:

AIR FILTERS

Vacuum and wash standard foam filters. Replace medium efficiency filter if present.

DRAIN PANS AND INTERIOR OF UNIT

Wash the foil faced insulation surfaces and wipe the drain pans with a soft cloth and mild cleaning solution. Check the drain fittings to ensure they are draining freely.

HEAT RECOVERY CORE

The heat recovery core must be handled with care. It is recommended that it be washed once a year following the season of most intense use, in order to ensure maximum efficiency of the partitions.

Allow the heat recovery core to soak for three hours in warm water and mild soap. Rinse under a heavy stream of water.

CAUTION

Hot water and a strong cleaning agent could damage the polypropylene core. Ensure the core is reinstalled in the unit in the correct orientation. Use the sticker as a guide.

ERV HM CORE

CAUTION

Do not soak the ERV HM core in water. This core can easely be damaged especially if it is soaked.

For ERV HM core, use a vacuum cleaner or low pressure air jet. It is not recommended to use solvents or detergents as these may damage the media or structure of the core.

FANS

Blower wheels and fan housing should be checked for dirt build-up. If they appear dirty, it may be necessary to remove the blower assembly and then vacuum the dust out through the fan mouth. See next column for instructions on removing the blower assembly.

SYSTEM OPERATION CHECK

Verification of all control modes should be checked to ensure proper operation. Refer to 3.2 Sequence of Operation section.

TESTING AND REPLACEMENT OF THE DAMPER ACTUATOR

Check damper operation by switching between LOW - COM or HIGH - COM on the dry contact terminal or by switching through the modes on the optional remote wall control. If the damper does not respond in one or both directions, check all connections.

7000 unit ONLY: Check for 24 volt output between the WHITE/RED and the WHITE/ORANGE wires at the damper motor. If 24 volts can be measured at the damper motor, the problem is either in the connections, the defrost relay or the main circuit board.

6LC/12LC units ONLY: (CAUTION: 120 VAC) Check for 120 volt output across theWHITE/BLACK wires.If 120 volts can be measured at the motor, replace the motor. If 120 volts cannot be measured at the motor, check pins J1-9 at the printed circuit board.

MAIN CIRCUIT BOARD REPLACEMENT

The main circuit board must be replaced if an electronic problem arises.

For example, the unit suddenly stops, the unit stays in defrost all of the time or if control functions are not working properly.

Ensure that power is reaching the board. Test the blower motors and damper actuators for operation when directly connected to the appropriate power voltage.If the motor and damper actuators function normally, replace the main circuit board.

MOTOR AND BLOWER REMOVAL AND INSTALLATION

Disconnect power from the unit. To determine if the fan motor is burned out, disconnect the four-wire service connector between the motor and cabinet. Connect the motor directly to a 115 volts power source with an electrical cable, as follows:

RED + WHITE

Low speed

 

 

BLUE + WHITE

Medium speed

 

 

BLACK + WHITE

High speed

 

 

If the motor functions normally, there is a problem with the wiring connections or the main circuit board. Check all wiring and replace main circuit board if necessary.

If the blower does not run, it must be replaced. To replace the motor,remove the recovery core or energy recovery core from the unit. Disconnect the four-wire service connector from the unit.Remove the fasteners holding the motor assembly in place. Lift the assembly up and out, using one hand under the motor and one hand to steady it. Remove the assembly carefully from the unit to avoid damage to the insulation, shelf, etc. Install the repaired motor assembly by following these instructions in reverse.
