Hi-Velocity RPM-E-50 Installatiehandleiding

Mounting the RPM-E

Two L mounting brackets are shipped loose for attaching the

RPM-E to the fancoil, 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

from the bottom of the coil. This will prevent

(76mm)

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.

Secondary Drain Pan

Some building codes call for the use of a secondary drain pan

underneath the entire unit (Fig. RPM-05). 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.

Drain Connections

All RPM-E modules come with a ¾"

secondary outlet. The condensate drain must have a vented p-trap

installed (Fig. RPM-05), and run at a slope of ¼"

foot in the direction of the drain. When installing the P-trap, one

must be installed on both the primary and secondary outlets. The

P-traps must have a minimum depth of two inches

to the high negative pressure of the blower system, the RPM-E

will hold some amount of water during operation. Once this level

has been achieved, condensate will flow from the coil regularly.

When the unit shuts down, or lowers speed, the force is released,

allowing the held condensate to empty from the drain pan.

During this time, condensate may flow from both the primary

AND secondary drains.

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.

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.
