Receiving and unpacking the APW
All of the APW water heaters are shipped fully assembled and
ready for installation; therefore, installation will consist of the
following tasks:
• Unpack the APW water heater from its shipping container
• Position and secure the APW water heater at the site
• Connect the heating loop/system piping to the APW
• Connect the Domestic Hot Water (DHW) piping to the
APW
• Connect external AC power to the APW electronic
control box
• If required, connect ModBus control wiring to the
temperature controller in the electronic control box
Each APW water heater is shipped as a single crated unit.
The unit must be moved with the proper equipment (forklift,
pallet jack, etc.) to avoid possible injury to personnel or
damage to the shipping container or unit. The shipping
carton should be inspected for damage incurred during
transit prior to signing the bill of lading.
Setting the unit
APW water heaters contain two (2) round cutouts on the frame
plate and two (2) on the pressure plate of the heat exchanger
(FIG. 2-1). Use these tabs or cutouts to lift and move the unit
as specified in the heat exchanger (HEX) manual supplied with
the unit.
In multiple unit installations, it is important to plan the
position of each unit in advance. Sufficient space for piping
connections and future service/maintenance requirements must
also be taken into consideration. All piping must include ample
provisions for expansion.

NOTICE
Unpack the APW water heater from its shipping container
taking care not to damage the unit when cutting away the

its shipping skid. Perform a complete visual inspection of the
unit to ensure there is no evidence of damage.
CAUTION
While packaged in the shipping container,
the heater must be moved using a forklift
or pallet jack. After unpacking, the
heater should be lifted and moved using
