Aquazone™ water source heat pump systems.
Water source heat pumps (WSHPs) are single-package
horizontally and vertically mounted units with electronic controls
designed for year-round cooling and heating.
IMPORTANT: The installation of water source heat pump units
and all associated components, parts, and accessories which
make up the installation shall be in accordance with the
regulations of ALL authorities having jurisdiction and MUST
conform to all applicable codes. It is the responsibility of the
installing contractor to determine and comply with ALL
applicable codes and regulations.
INSPECTION
Upon receipt of shipment, carefully check the shipment against
the bill of lading. Make sure all units have been received. Inspect
the carton or crating of each unit, and inspect each unit for damage
on both the interior and exterior. Ensure the shipping company
makes proper notation of any shortages or damage on all copies of
the freight bill.
Concealed damage not discovered during unloading must be
reported to the shipping company within 5 days of receipt of
shipment.
NOTE: It is the responsibility of the purchaser to file all necessary
claims with the shipping company.
STORAGE
If the equipment is not needed for immediate installation upon its
arrival at the job site, it should be left in its shipping carton and
stored in a clean, dry area between 50°F and 95°F. Units must only
be stored or moved in the normal upright position as indicated by
service,
the UP arrows on each carton at all times. If unit stacking is
required, stack units as follows: vertical units less than 6 tons, no
more than two high; horizontal units less than 6 tons, no more than
three high. Do not stack units larger than 6 tons.
Step 1 — Check Jobsite
