FHP EV Series Installation And Maintenance Manual - page 2
INTRODUCTION:
The EV Series uses a scroll compressor and refrigerant R-
410A to achieve high efficiency levels, quiet operation and
reliable performance.
The new refrigerant provides performance similar to that of R-
22 with one major advantage. Refrigerant R-410A is an HFC
so it does not contain any ozone depleting HCFC's or CFC's.
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 15 days of receipt.
GENERAL DESCRIPTION:
The EV Water-to-Air 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 EV Water-to-Air Heat Pumps are Underwriters
Laboratories (UL) and (cUL) listed for safety. The EV Water-to-
Air Heat Pumps are designed to operate with entering fluid
temperature between 25°F to 75°F in the heating mode and
between 50°F to 110°F in the cooling mode.
NOTE: 50°F Min. EWT for well water applications with
sufficient water flow to prevent freezing. Antifreeze solution is
required for all closed loop applications. 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.
WARNING: This product should not be used for temporarily
heating/cooling during construction. Doing so may effect the
units 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, no more than two high.
Horizontal units, no more than three high.
SAFETY CONSIDERATIONS:
CAUTION: R-410A systems operate at higher pressures than
standard R-22 systems. Do not use R-22 service equipment
or components on R-410A equipment.
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.
WARNING: 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.
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 in areas that are subject to
freezing.
INSTALLATION:
WARNING: Remove all shipping blocks under blower
housing. Loosen compressor mounting bolts.
MOUNTING VERTICAL UNITS:
Vertical units up to five tons
are available in left, right,
front, or rear air return
configurations. Vertical units
should be mounted level on
a vibration (Figure #1)
absorbing pad slightly larger
than the base to minimize
vibration transmission to the
building structure. It is not
necessary to anchor the
unit to the floor.
MOUNTING
HORIZONTAL UNITS:
While horizontal units
may be installed on any
level surface strong
enough to hold their
weight, they are
typically suspended
above a ceiling by
threaded rods. The rods
are usually attached to
the unit corners by
hanger Bracket kits (P/N 930-004, or 006). (See Figure #2).
The rods must be securely anchored to the ceiling. Refer to
the hanging bracket assembly and installation instructions for
details. (See unit horizontal detail drawing). Horizontal units
installed above the ceiling must conform to all local codes. An
auxiliary drain pan if required by code, should be at least four
inches larger than the bottom of the heat pump. Plumbing
connected to the heat pump must not come in direct contact
with joists, trusses, walls, etc..
