INITIAL INSPECTION
Be certain to inspect all cartons or crates on each
unit as received at the job site before signing the
freight bill. Verify that all items have been received
and that there are no visible damages; note any
shortages or damages on all copies of the freight
bill. In the event of damage or shortage, remember
that the purchaser is responsible for filing the
necessary claims with the carrier. Concealed
damages not discovered until after removing the
units from the packaging must be reported to the
carrier within 24 hours of receipt.
GENERAL DESCRIPTION
These Packaged System Heat Pumps provide the
best combination of performance and efficiency
available. Safety devices are built into each unit to
provide the maximum system protection possible
when properly installed and maintained.
The EP Water-to-Air Heat Pumps conform to UL1995
standard and are certified to CAN/CSA C22.1 No
236 by Intertek-ETL. The Water-to-Air Heat Pumps
are designed to operate with entering fluid
temperature between 25°F to 80°F in the heating
mode and between 50°F to 110°F in the cooling
mode. Efficiencies and capacities will vary as
entering fluid and return air temperatures vary.
Caution
50°F Min. EWT for well water applications with
sufficient water flow to prevent freezing.
Antifreeze solution is required for all closed loop
applications where the fluid temperature may drop
below 50°F. Cooling Tower/Boiler and Earth
Coupled (Geo Thermal) applications should have
sufficient antifreeze solution to protect against
extreme conditions and equipment failure. Frozen
water coils are not covered under warranty.
Caution
This product should not be used for temporarily
heating/cooling during construction. Doing so
may affect the unit’s warranty.
MOVING AND 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. Units must only be stored or moved in the
normal upright position as indicated by 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.
SAFETY CONSIDERATIONS
Installation and servicing of this equipment can be
hazardous due to system pressure and electrical
components. Only trained and qualified personnel
should install, repair, or service the equipment. Untrained
personnel can perform basic functions of maintenance
such as cleaning coils and replacing filters.
Caution
Before performing service or maintenance
operations on the system, turn off main power to
the unit. Electrical shock could cause personal
injury or death.
When working on equipment, always observe
precautions described in the literature, tags, and
labels attached to the unit. Follow all safety codes.
Wear safety glasses and work gloves. Use a
quenching cloth for brazing, and place a fire
extinguisher close to the work area.
The blower motor should only be operated when a
duct is installed and secured to heat pump duct
collar in order to avoid possible injury.
LOCATION
Locate the unit in an indoor area that allows easy
removal of the filter and access panels, and has
enough room for service personnel to perform
maintenance or repair. Provide sufficient room to
make fluid, electrical, and duct connection(s). If the
unit is located in a confined space such as a closet,
provisions must be made for return air to freely
enter the space. On horizontal units, allow
adequate room below the unit for a condensate
drain trap and do not locate the unit above supply
piping. These units are not approved for outdoor
installation; therefore, they must be installed inside
the structure being conditioned.
Do not locate units in areas that are subject to
freezing.
