EC Series
NOTE: 50° Minimum Entering Water
Temperature (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
Geothermal applications should have sufficient
antifreeze solution to protect against extreme
conditions and equipment failure. Frozen water
coils are not covered under warranty.
NOTE: This product should not be used for
temporarily heating/cooling during construction.
Doing so may Affect 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.
For storage If unit stacking is required,
stack units as follows:
Do not stack units larger than 6 tons.
Vertical units less than 6 tons, no more than
two high.
Horizontals units less than 6 tons, no more
than three high.

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 face of unit's air coil. On horizontal
units, allow adequate room below the unit for a
condensate drain trap and do not locate the unit
above supply piping.
NOTE: 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

MOUNTING VERTICALLY

Vertical units up to six tons are available in left or
right air return configurations. Vertical units
should be mounted level on a vibration 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.
(See Figure #3).
Figure # 3

MOUNTING HORIZONTALY

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 the
base frame support rails , with mounting holes present
(See Figure #4). The rods must be securely anchored
to the ceiling. 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.some
applications require an attic floor installation of
the horizontal unit. In this case the unit should be
set in a full size secondary drain pan on top of a
vibration absorbing mesh. The secondary drain
pan prevents possible condensate overflow or
water leakage damage to the ceiling. The
secondary drain pan is usually placed on a plywood
base isolated from the ceiling joists by additional
layers of vibration absorbing mesh. In both cases,
a 3/4" drain connected to this secondary pan
should be run to an eaves at a location that will be
noticeable.
