EKW FX10 INSTALLATION MANUAL
Safety Advisements
Installation and servicing of heating and air conditioning equipment can be hazardous due to system pressure and electri-
cal components. Only trained and qualified service personnel should install, repair or service heating and air conditioning
equipment.
When working on heating and air conditioning equipment, observe precautions in the literature, tags and labels attached
to the unit as well as other safety precautions that may apply, such as the following safety measures:
Follow all safety codes.
•
Wear safety glasses and work gloves.
•
Use a quenching cloth for brazing operations.
•
Have a fire extinguisher available for all brazing operations.
•
Moving and Storage
Move units in the normal “up” orientation. Do not stack more than two units in total height. When the equipment is
received, all items should be carefully checked against the bill of lading to be sure that all crates and cartons have been
received. Examine units from the cartons if necessary. Units in question should also be internally inspected. If any damage
is noted, the carrier should make the proper notation on the delivery receipt, acknowledging the damage.
Unit Location
Locate the unit in an indoor area that allows easy removal of the access panels and has enough space for service
personnel to perform maintenance or repair. Provide sufficient room to make water and electrical conditions. Units may be
stacked vertically in small mechanical rooms. These units are not approved for outdoor installation and, therefore, must be
installed inside the structure being conditioned. Do not locate in areas subject to freezing.
Piping
Both source as well as load fluid piping must be at least as large as the unit connections on the heat pump (larger on long
runs).
Process Water Applications
For process water applications, it is recommended that a secondary load heat
exchanger be installed to prevent corrosion to the unit’s primary coaxial coil. In
situations where scaling could be heavy or where biological growth such as iron
bacteria will be present, a closed loop system is recommended. Over a period of
time, ground water unit heat exchanger coils may lose heat exchange capability
due to a buildup of mineral deposits. These can be cleaned only by a qualified
service mechanic as special pumping equipment and solutions are required. Never
use flexible hoses with a smaller inside diameter than that of water connections.
Mounting Units
Units should be mounted level on a vibration absorbing pad slightly larger than
the base to provide isolation between the unit and the floor. It is not necessary
to anchor the unit to the floor. Allow access to front access panel for servicing
compressor.
WARning:
Before performing service or maintenance operations on the system, disconnect all
power sources to unit. electrical shock could cause personal injury. Before applying power to the
unit, make sure that all panels and screws are in place. Failure to do so could cause risk of electri
-
cal shock.
