UNIT PLACEMENT
3.4 STORAGE
Units that must be stored prior to installation should be left on their pallets and protected from
weather and physical damage. Units must be placed on a level surface to prevent wracking of
the pallet and the HE1.5XIN. All access doors must be secured with all available hardware (door
latches and securing bolts) and all openings into the cabinet must be sealed to prevent entry of
dust, dirt and debris.
4.0 UNIT PLACEMENT
4.1 BEFORE YOU BEGIN
Units that must be stored prior to installation should be left on their pallets and protected from
weather and physical damage. Units must be placed on a level surface to prevent wracking of
the pallet and the HE1.5XIN. All access doors must be secured with all available hardware (door
latches and securing bolts) and all openings into the cabinet must be sealed to prevent entry of
dust, dirt and debris.
The HE1.5XIN is designed for installation in a sheltered location, out of the weather. The
preferred mounting location is to place the unit on a concrete floor, although it can also be
suspended from a ceiling or other structural support. See Section 5.3, Suspended Mount, in this
manual.
For all installations, maintain needed service clearances as shown on the dimensioned drawings
located in Section 4.2 of this manual. In addition, if the optional Bypass Economizer is ordered,
additional clearance will be required for the extra bypass duct. See the
RenewAire Supplemental
Manual for Bypass
or further information and clearance details specific to the HE1.5XIN units.
For all floor-mount installations, the unit should be set on its factory-provided adjustable legs
and leveled. Select a location that is central to the inside duct runs and close to both the
exhaust duct (to the outside) and also to the fresh air duct (from the outside).
The exhaust outlet and the outside air inlet on the outside of the building should be at least 10'
apart to avoid cross-contamination. Comply with all local building codes in the positioning of the
duct openings. Do not position the exhaust air outlet in a location where it will dump exhaust
air into any enclosed or occupied space. The duct inlets and outlets should be screened against
insects and vermin and should be shielded from the weather to prevent entry of rain or snow.
