1 Safety Considerations
Hazards may exist within this equipment because it
contains electrical and powerful moving components.
Only qualified service personnel should install or
service this equipment. Untrained personnel can perform
basic maintenance such as maintaining filters.
Observe precautions marked in literature and on
labels attached to unit. Follow all safety codes.
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
exchange 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 Heat Recovery Ventilators have minimum
clearance requirements when mounting. See Appendix B
for specific clearance requirements. Mounting options
must allow 6" (152mm) 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. The
area should also be easily accessible for maintenance.
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 #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" (10mm)
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 outside may have 1" to 2" (25 to 51mm) 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) (6mm/305mm). 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:
NOTE:
Duct sizes are for connection purposes only.
Ducts should be sized to keep noise and pressure drop
to a minimum.
WARNING
Disconnect main power switches to unit before
performing service or maintenance. Electric shock
can cause personal injury or death.
