Hi-Velocity RPM-E Series Instrukcja instalacji

Refrigerant Modules (RPM-E)

The RPM-E series cooling module can be used with the Hi-

Velocity Fancoil, installed in many different positions. It is pre-

piped with an adjustable, heat pump ready, thermal expansion

valve and comes with a bleed port, sight glass, suction and liquid

line access ports, freeze-stat, and two L brackets for mounting.

The RPM-E comes as a complete module and must be installed

in the vertical position on the return air side of the fancoil; the

unit cannot be turned on its side and is a draw through unit

only. The module offers multi-position airflow configurations

for horizontal, highboy, or counter-flow configurations. (Fig.

RPM-01)

The TXV (Thermal Expansion Valve), sight glass, access

ports, and freeze-stat* are already installed and are accessible

through an easy to remove access hatch. The liquid and suction

lines have male solder connections at a standard width making

connections to the condenser lines quick and easy.

*IMPORTANT:

The freeze control serves the

purpose of preventing severe icing of the coil in the

event of an undercharge or low load on the coil. This

piece of equipment must be used at all times. Lack

of use of the freeze-stat will result in RPM-E related

warranty issues being voided.

Configurations

When installing, follow the recommendations shown in

Table 01, demonstrated in Fig. 01. For example, a horizontal

application could use A to B while highboy applications could

use A to B1. Do not use a combination of A to A1 or B to B1,

as this would bypass the cooling coil completely. A1 is not

to be used for outlet airflow. The knock-outs can be removed

with a screw driver and hammer. Use caution when opening

the knock-outs, ensuring you do not damage the coil surface.

RPM-E Drain Pan Extension

The RPM-E Drain Pan Extension (DPE) is to be removed for

up flow (vertical) return air applications (avoid installing the

RPM-E in counter flow applications).

To remove the pre-installed DPE, first remove left side access

panel of the RPM-E Module. Remove the 3 - ¼ " screws

that hold the DPE in place, remove the DPE and replace ¼"

screws into the coil support (Fig. RPM-02). Replace the left

side access panel.

The lower knockout can now be removed, using a screwdriver

and hammer (Fig-RPM-03). Use caution when removing

knockouts ensuring you do not damage the coil inside the

module.
