About this file

Written by GovTribe AI · Mar 4, 2026

This document is a set of design plans and specifications for a communications room HVAC upgrade at the Great Plains Dispatch Center, located at the Black Hills National Forest in Rapid City, South Dakota, managed by the U.S. Department of Agriculture Forest Service, Rocky Mountain Region.

The project involves removal of an existing two-ton ductless split system air conditioning unit (AC-1 and condensing unit CU-1) and installation of two new two-ton ductless split systems. The first new system (AC-2 and CU-2) will be installed adjacent to the existing system location, utilizing new wall-mounted plywood backboards, a new electrical disconnect switch, fully insulated refrigerant piping, and a new concrete equipment pad. The existing system will be replaced in its original location (AC-1 and CU-1) reusing the existing plywood backboard, electrical disconnect switches, refrigerant piping, and concrete pad. Both systems are Carrier models (40MHQ24-3 and 38MHR24-3) with R-32 refrigerant, 22,890 BTU cooling capacity, and 14.3 SEER rating. Additional work includes evacuation and protection of existing refrigerant piping, lockout/tagout procedures for electrical disconnection, installation of two new electrical circuit breakers in existing panel LP2, and installation of an emergency power off (EPO) shunt trip push-button adjacent to the existing EPO switch. The design documents include mechanical plans with demolition and new work layouts, electrical plans with power distribution details, and reference plans from the original 2012 as-built construction. Designer Alberta Settle and Forest Engineer Ralph Adam prepared the plans, dated May 2025.

GENERAL NOTES

1. REMOVE EXISTING DUCTLESS SPLIT SYSTEM AIR CONDITIONING SYSTEM (INDOOR WALL-MOUNTED FAN COIL UNIT

(AC-1) AND OUTDOOR PAD-MOUNTED CONDENSING UNIT (CU-1)) AND DISPOSE OF BOTH ITEMS.

2.EVACUATE REFRIGERANT CHARGE FROM EXISTING DUCTLESS SPLIT SYSTEM AIR CONDITIONING SYSTEM. CAP AND

PROTECT EXISTING REFRIGERANT PIPING FOR REUSE.

3.DISCONNECT EXISTING ELECTRICAL CONNECTIONS FROM INDOOR AND OUTDOOR COMPONENTS OF THE EXISTING

DUCTLESS SPLIT SYSTEM AIR CONDITIONING SYSTEM. USE LOCKOUT/TAGOUT PROCEDURES TO KEEP EXISTING

INDOOR AND OUTDOOR DISCONNECT SWITCHES SECURE.

4.PROVIDE AND INSTALL NEW TWO-TON (NOMINAL 24 MBH) DUCTLESS SPLIT SYSTEM AIR CONDITIONING SYSTEM.

INSTALLATION SHALL REUSE EXISTING INDOOR PLYWOOD BACKBOARD FOR WALL-MOUNTING OF INDOOR FAN COIL UNIT, ELECTRICAL DISCONNECT SWITCHES, REFRIGERANT PIPING, AND CONCRETE PAD FOR SECURING OUTDOOR CONDENSING UNIT. THE COMPONENTS OF THIS NEW DUCTLESS SPLIT SYSTEM AIR CONDITIONING SYSTEM SHALL

BE DESIGNATED AC-1 AND CU-1.

5.PROVIDE AND INSTALL NEW TWO-TON (NOMINAL 24 MBH) DUCTLESS SPLIT SYSTEM AIR CONDITIONING SYSTEM ADJACENT TO THE EXISTING SYSTEM. INSTALLATION SHALL INCLUDE A NEW SECTION OF PLYWOOD FOR WALL-MOUNTING OF THE INDOOR FAN COIL UNIT, A NEW ELECTRICAL DISCONNECT SWITCH, FULLY INSULATED REFRIGERANT LIQUID AND SUCTION PIPING, AND A NEW CONCRETE PAD FOR SECURING THE NEW OUTDOOR CONDENSING UNIT. THE COMPONENTS OF THIS NEW DUCTLESS SPLIT SYSTEM AIR CONDITIONING SYSTEM SHALL

BE DESIGNATED AC-2 AND CU-2.

6.INSTALL AN EMERGENCY POWER OFF (EPO) SHUNT TRIP PUSH-BUTTON FOR THE NEW AIR CONDITIONING SYSTEM.

LOCATE THE NEW EPO ADJACENT TO THE EXISTING EPO SWITCH.

7.INSTALL TWO NEW ELECTRICAL CIRCUIT BREAKERS IN EXISTING PANEL LP2 TO SERVE THE NEW AC-2 AND CU-2

CIRCUITS.
