RECEIVING & INSPECTION OF UNITS
• Do not operate unit while
access doors are open. This
may cause personal injury.
• Do not operate unit until
all duct work is
connected, unless you are
familiar with the entire
system and fully
experienced in fan service
and energy recovery
ventilator service work.
• Clear the area of all
unauthorized personnel if
system must be operated
with access panels off, or
establish sufficient guards
or warning signs keeping
unwary bystanders out of
danger.
• Whenever the system is
being inspected internally,
“lock-out” the power
supply to the ERV, either
at the disconnect located
on the unit (optional), or
the “main” disconnect
located prior to the
packaged system.
PRACTICAL TIPS
Upon receipt of the unit(s) to the job site, inspect the unit for shipping damage. Open all access panels and
inspect the interior and exterior. If any damage exists, do not accept the shipment without written acknowl-
edgement of the damages by the shipper. Report damage to the carrier and to Systemair Inc. immediately.
Note type of damage on copy of Bill of Lading.
CAUTION
Before installation, careful consideration must be given to how this system will operate if connected to any
other piece of mechanical equipment, i.e. air handler, operating at a higher static. After installation, the
compatibility of the two pieces of equipment must be confirmed by measuring the airflows of the Energy
Recovery Ventilator. It is always important to assess how the operation of any ERV may interact with vented
combustion equipment (i.e. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.).
NEVER
- install a ventilator in a situation where its normal operation, lack of operation or partial failure may
result in the backdrafting or improper functioning of vented combustion equipment!!!
CAUTION
• This product is to be installed only by a trained, experienced service technician or licensed electrician.
• Read and follow these instructions carefully as failure to follow them may cause an unsafe condition or damage the
equipment.
Pre-Installation Considerations
All Systemair units are provided with rigging holes. See LIFTING INSTRUCTIONS on the following pages
before handling the units.
1. Make sure the unit is level to eliminate water accumulating in undesired areas.
2. Thermally insulate duct work to and from unit to prevent unnecessary heat losses.
3. Provide adequate straight inlet and outlet transitions to the unit. Use turning vanes when abrupt turns are
unavoidable.
4. Duct work must be supported independently.
5. Rough-in for electrical wires
Safety Precautions
Testing, adjusting, start-up, and maintenance of Energy Recovery Equipment exposes personnel to potential
safety hazards. Only experienced mechanical personnel who are aware of these safety hazards created by
moving or rotating components internal to the packaged units should be authorized to work on the Energy
Recovery packaged system. It is assumed that these personnel will take the proper precautions to prevent
injury from moving parts. Many systems are of the low pressure, low velocity type that appear relatively
harmless. However, some systems have an added danger of high velocity and relatively high pressure air
movement which can blow or suck people off balance or blow dust or dirt in their eyes.
