Product Description
The DIVERSITECH hpr-3 is a one-piece, gray plastic heat pump riser designed to elevate heat pumps, condensers, and air handlers 3 inches above the mounting surface. It is rated to support up to 500 pounds, making it suitable for standard residential condensing units and air handlers. The riser mounts using butyl mastic for a secure, vibration-dampening connection to the pad or base. HVAC technicians install this riser as part of routine equipment placement, particularly in climates where seasonal snow accumulation or condensate ice buildup poses a risk to equipment coils and bases.
This riser is used in ducted HVAC applications where equipment needs to be lifted above grade, concrete pads, or rooftop surfaces. Its most common application is elevating heat pumps above the anticipated snow line to reduce ice damage to coils caused by condensate drainage during heating-mode operation. It is also used under air handlers and condensing units where minor elevation improves drainage clearance or airflow at the base of the unit.
Key Features
- One-piece construction for straightforward placement without assembly
- 3-inch elevation lifts equipment above snow line and improves base drainage
- 500-pound load capacity supports standard residential heat pumps and condensers
- Gray color matches common equipment pad and housing finishes
- Butyl mastic mounting method provides secure, vibration-resistant adhesion
- Plastic construction resists corrosion and weathering in outdoor installations
Compatibility
Designed as an OEM-style support riser for ducted residential heat pumps, condensing units, and air handlers requiring 3 inches of elevation at the base.
Installation Notes
Installation is typically performed by a licensed HVAC technician as part of new equipment placement or equipment repositioning during service. Power to the unit must be disconnected at the disconnect block or breaker before repositioning any equipment on the riser. Apply butyl mastic to the base contact surface per the manufacturer instructions before setting the unit onto the riser. Verify that the riser is level and that the supported unit weight does not exceed the 500-pound rated capacity.
