3 PRE-INSTALLATION PREPARATION

NOTE: Before installing unit, determine whether any building alterations are required to run piping,

wiring and duct work. Follow the figures, specifications, and listed requirements for proper clearances.

Proper preparation of the installation location and consideration of the installation environment optimizes

the performance of your VRC.

3.1 Cabinet and Room Requirements

To ensure the proper operation of the VRC, you must install the unit in a sealed cabinet in a room that

meets the following requirements:

• The cabinet must be moisture proof and free from air leaks that could destabilize the

temperature gradient.

• The cabinet must have appropriate thermal insulation and a sealed, moisture-proof layer.

• Minimize the amount of outdoor air entering the equipment room to prevent an unnecessary

load increase. We recommend keeping the leak rate of outdoor air below 5% of the total indoor

airflow.

• All room doors and windows should be closed properly to avoid infiltration of outside into the

room.

• Consider the weight-bearing capacity of the room floor because the weight of the system will

increase as equipment is added to the cabinet.

• Do not install the unit outdoors.

3.2 Environmental Requirements

Observe the following requirements and the operating conditions listed in Table 3.1 below, when

planning installation.

• Keep the unit away from flames or any heat source.

• Do not install in a location where the unit is exposed to direct sunlight.

• Do not install where the unit is exposed to corrosive gas or organic solvents.
