Code Required Clearances:
In addition to the previously stated clearance requirements, follow all applicable local, state, and national
requirements relative to spacing from other objects or equipment.
Placement of Heater
Indoor installations can be problematic, and for that reason are discouraged. However, if no viable
alternative exists, indoor installations may be successfully accomplished provided very exacting criteria
is addressed. Every indoor installation is unique; therefore, there are no specific guidelines for this
type of installation. If considering an indoor installation, you are strongly urged to contact the AquaCal
Engineering department (800-786-7751) for assistance prior to proceeding.

Service and Operational Clearances:
• To operate correctly, heat pumps require large volumes of air moving over the heat collector.
Allow adequate clearance between the heat pump and walls, fences, shrubs, or other objects.
Refer to required clearance drawings below.
• Allow five (5) feet of vertical clearance between the top of the heat pump and any roof
overhang or other obstruction. This clearance prevents cold discharge air from recirculating
back into the heat pump (recirculation would reduce the overall performance of the heat pump).
• The access panel requires removal during installation and service. Do not place plumbing, or
other items, closer than 30” from the front of the heater.
