Inspection on Arrival
Inspect the equipment exterior and interior for any dam-
age on arrival that may have occurred during unit ship-
ment and for shipped loose parts. Ensure that there is no
damage to any protruding exterior components such as
the access door, door latches, door hinges, duct collars,
cabinet, etc. or to internal components such as fans, mo-
tors, flat plate heat recovery module, dampers, actuators
and drain pans. File a claim with the shipping company
if the unit is damaged. Check the packing slip against all
items received. If any items are missing, sign the carrier’s
bill of lading with the notation “Shipment Received Less
Item #___”. Contact the factory immediately if damage
is found. No return shipment will be accepted without
authorization.
Unit Application Limitations
Using Venmar CES units for temporary ventilation dur-
ing construction is subject to the unit warranty terms and
should be reviewed carefully before proceeding, as this
may void the standard warranty conditions.
Fine dust, larger particulate matter, solvents, varnishes and
other chemicals may cause filter clogging and elevated
cabinet pressures, higher power consumption and possible
irreparable damage to the flat plate heat recovery module,
which could reduce energy recovery performance of the
plate and damage to other components. Potential dam-
ages include, but are not limited to, these examples.
Installation
Unit Location Requirements
Consult local building codes and electrical codes for spe-
cial installation requirements and note additional require-
ments listed in this manual. In choosing the installation
location of the unit, consider the following factors:
• The unit must be mounted in a heated area to pre-
vent condensate lines from freezing.
• When possible, mount the unit away from occupied
areas to provide quiet operation.
• The unit should be installed to allow easy access for
maintenance. See Appendix B for dimensions and
recommended service and maintenance clearances.
• The unit should be mounted close to an exterior
partition to minimize the length of insulated duct-
work required. Outdoor air intakes and exhaust air
discharge should be separated by a minimum of 10
feet [3,000 mm] for Class 2 exhaust or as required by
ASHRAE 62.1 to avoid outside cross contamination.
• The fresh air intake must be positioned away from
sources of contamination such as hot chimneys or
kitchen exhaust vents.
• The unit should be mounted close to a drain and
120V, 60 Hz power supply.
• The unit should be mounted away from hot chim-
neys, electrical panels and other hazards.
• Locate the unit in an area requiring the least amount
of ductwork and directional changes to allow opti-
mum performance, to reduce pressure loss and to
achieve proper ventilation. Ductwork must be in ac-
cordance with ducting mechanical rules to prevent
sound issues and system effects. See Ductwork and
Appendix C for recommendations on ductwork.
• The unit should be mounted on a level foundation to
allow condensation to flow into internal drains Space
must be left under the unit to allow for drain trap
height and connection of drain lines. See Appendix D
for specific trap height and connection requirements.
IMPORTANT
Mounting options must allow 12” [305 mm] clearance in
front of the control box cover for access.
IMPORTANT
The exhaust dampers for indoor units (if ordered) are not
installed from the factory and must be installed on site.
See Exhaust Dampers for Indoor Units.
WARNING
Venmar CES equipment is not designed to be used for
temporary heating, cooling and/or ventilation during
construction.
