Model SCM Air to Water Heat Pump — Installation, Operation & Maintenance Manual
Section 5: Location & Mounting
Failure to comply with all of the guidelines
IN THE FOLLOWING could result in death,
serious injury or substantial property damage.
The installation must comply with all applicable
local codes.
Prepare the unit
• Inspect the unit for shipping damage. DO NOT use if there is
a risk that the damage could affect unit operation.
• Make sure all required components are available.
• Install optional immersion heater, if used. See instructions
provided with the heater.
Location
• DO NOT locate where the unit could be sprayed by sprinklers.
• DO NOT locate near swimming pools, spas or any location
that could cause chlorine or other contaminant to enter the
unit.
• DO NOT locate where water run-off from adjacent structures
could impinge on the unit.
• Maintain the clearances shown in Figure 10.
• LOW AMBIENT conditions — Contact SpacePak Technical
Support to obtain low ambient adjustment instructions if
cooling operation below 55°F is required.
• CORROSIVE ENVIRONMENTS — Do not install the unit in
an area subject to sea air or other potential corrosive
contaminants.
• INDOOR INSTALLATION — If the unit is installed inside a
building, the building must be equipped with air openings
sufcient to ensure free discharge of heated (or cooled) air
generated by the heat pump. All clearances must be
maintained to ensure free air ow into and out of the
enclosure. Make sure no other equipment located in the
space will be affected by the unit’s air ow.
Handling
• See Figure 9.
• Place padding at pressure points to prevent damage to the
enclosure.
• Use caution when handling. The unit is heavy and could
cause severe injury or damage if dropped or handled
incorrectly.
Mounting pad
• The SpacePak heat pump must be mounted on a
level, corrosion and weather-resistant mounting surface,
preferably concrete. The structural support must be
suitable for the operating weight of the unit and attached
components, its mounting pad, snow loading and any other
expected loads.
• The mounting pad must not be attached directly to a structure
where noise transmission can occur.
• Vibration isolators supplied with the heat pump may be in-
stalled when desired to reduce transmitted vibration.
• The unit must be bolted securely to the pad. Where required
by local jurisdiction, the mounting must also be analyzed for
seismic loading capability.
• The mounting must ensure that there will be no debris
accumulation which might block air ow through the
enclosure openings. The lower edge of the lower fan
opening must be above the typical snow line, including
allowance for drifting.
• There must be no accumulation of water that could reach the
bottom of the unit’s enclosure.
