Hi-Velocity RPM-E-70 Manual de instalação

Mounting the RPM-E

Two L mounting brackets are shipped loose for attaching the

RPM-E to the fan coil, along with two sided foam tape for an air

seal between the units. When mounting the cooling coil to the

fancoil (Fig. RPM-04), ensure that no screws puncture the drain

pan or coil. It is advised that no screws be placed within 3 inches

(76mm) from the bottom of the coil. This will prevent the drain

pan from being accidentally pierced. It is also advised that care be

taken when placing screws in the top left side of the cooling coil

(when looking at the access hatch), as this is where the top most

extent of the cooling coil is located. See Specification Pages for

the dimensions of the fan coil units and cooling modules.

Outdoor Unit Installation

Locate the outdoor unit in a suitable location, as close as

possible to the fan coil. Maintain the clearances recommended by

the manufacturers of the outdoor unit, to ensure proper airflow.

The outdoor unit must be installed level, in a properly supported

location. A liquid line filter/drier is recommended to be installed.

Drain Connections, P - Trap &

Secondary Drain Pan

Important: Piping the condensate lines on a return side cooling

coil can be dramatically different, be sure to read info below.

The primary condensate drain must have a minimum 3"

P-Trap installed (Fig. 05). The drain line must run at a slope of

¼" per foot in the direction of the drain. RPM-E modules come

with a ¾" male CPVC primary and secondary outlet. It is good

practice to install a clean out right above the P-Trap. Using a

"tee fitting" and cap in the P-Trap's construction can be used as

the clean out and as a way to prime the P-Trap if it ever dries out.

A wet P-Trap is important. A dry P-Trap can be detrimental to

proper drainage. If code requires a secondary drain line, run the

secondary line using the same method as primary. Otherwise,

capping off the secondary drain line is acceptable. Do not run the

secondary drain line to the secondary drain pan or use it as a vent

to atmosphere! An equipment stand/riser or rubber equipment

mat may be necessary to elevate the module off of the ground to

allow for a P-Trap.

Any installation that has the potential of property damage

due to condensate must have a secondary drain pan installed. If

the unit is installed in a high heat and/or high humidity location,

extra insulation around the unit casing may be required. This will

prevent excessive condensate from forming on the outer surface

of the casing.

Wiring - Outdoor Unit

Make all connections to the outdoor unit with rain tight conduit

and fittings. Most building codes require a rain tight disconnect

switch at the outdoor unit as well (always check local codes). Run

the proper size copper wires to the unit, and connect as per the

manufacturer's recommendations.

Ensure that the outdoor unit is setup for a TX system. If not, a

hard start kit may be required.
