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” (305 mm)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” (10 mm) 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” (25 mm to 51 mm) 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) (6 mm/305 mm). 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
6LC, V6LC, 12LC, V12LC 14” x 8” (356 mm x 203 mm)
7000 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 6LC, V6LC, 12LC and V12LC units have 1” (25 mm)
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 7000 unit have 2” (51 mm) 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. (2 m/sec.) 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. (5.6 m/sec.)
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. Installation (cont’d)
3. Controls
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” (6 mm) 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 as follows:
140 inches (0.09 m).
2.7 Drains
The drain fittings provided with the unit will accept a 3/4” (19 mm) 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” (19 mm)
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 or 6 mm per 305 mm).
2.8 Electrical Connections
POWER
A terminal block and strain relief bushing or a junction box is
provided for line voltage to make the necessary power connections.
The electrical requirements are as follows:
6LC, V6LC 7000 12LC, V12LC
VO LTAGE 115 V115 V115 V
MCA 8.65 6.63 13.4
MOP 12.5 9.13 20
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.
S
PEED SELECTION (6LC, V6LC /12LC, V12LC 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 7000 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 6LC, V6LC, 12LC and V12LC 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 6LC, V6LC,
12LC and V12LC 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
fresh air from outdoors. For 6LC, V6LC, 12LC and V12LC units
only, if equipped with recirculation module, the internal defrost
damper opens recirculation opening.
• Power connected, FF control contacts close during unit ventilation
or defrost cycle.

5. Maintenance and Service
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 - 6LC, V6LC, 12LC and V12LC units
only). In cold temperatures, defrost cycles will remove frost from the
heat recovery core to maintain good operation.
E
XHAUST 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 or energy 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 (-5°C to -30°C) 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 6LC,
V6LC, 12LC and V12LC units. The defrost cycle is electronically
controlled in response to the outdoors temperature 23°F to -22°F
(-5°C to -30°C).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 6LC, V6LC, 12LC and V12LC 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.
POOL ELECTRONIC TYPE (FOR 7000 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
static pressure losses of both the supply and exhaust will aid in balancing
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.
5.1 Bi-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.

H
EAT 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.
CAUTION
Hot water and a strong cleaning agent could damage
the polypropylene core. Ensure the core is returned to
the unit in the correct orientation. Use the sticker as a
guide.
Allow the heat recovery core to soak for three hours in warm water
and mild soap. Rinse under a heavy stream of water.
ERV HM CORE
CAUTION
Do not soak the ERV HM core in water. This core can
easely be damaged especially if it is soaked.
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.
M
OTOR 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 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.

TWO SCREWS
LOCKING PLATE
CAPACITOR
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, V6LC/12LC, V12LC units ONLY: (CAUTION: 120 VAC) Check
for 120 volt output across the WHITE/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.
