2.4 Evaporator Installation
2.4.1 Room Preparation
The room should be well insulated and must have a sealed vapor barrier. Use
polyethylene as the vapor barrier of the ceiling and the wall. Paint on concrete walls
or floors should be vapor resistant.
Note
The most important requirement for maintaining environmental control in the conditioned
room is the vapor barrier.
Incoming fresh air should be kept to a minimum. Incoming outside air adds to the
heating, cooling, humidifying loads of the site. It is recommended that outside air be
kept below 5% of the total circulated in the room. Doors and windows should be
properly sealed to minimize leaks.
Chapter 2 Mechanical Installation 11
DataMate 3000 Series Air Conditioner User Manual
2.4.2 Location Consideration
Note
The DataMate3000 generates water. Water leaks can cause damage to sensitive system
nearby. Do not mount units near sensitive systems. Be sure to install a field-supplied pan
with a drain line.
1. Try to locate the evaporator in a capacious floor space to ensure normal
operation.
2. Avoid locations in confined areas that affect the airflow pattern and result in short
cycles and abnormal noise.
3. Do no install the unit in an alcove or at the extreme end of a long, narrow room.
4. Do no install multiple units close to each other. This can result in crossing air
patterns, uneven loads and competing operating modes.
5. Do not attach additional devices (such as smoke detectors, and so on.) to the
cabinet that will interfere with routine maintenance or service.

2.5 Condenser Installation
2.5.1 Location Considerations
1. The condenser should be located for maintenance accessibility and away from
residential areas. Avoid ground-level sites with public access.
2. Do no locate the condenser directly in the environment that requires low noise.
3. To ensure a satisfactory air supply, locate the condenser in a clean area, away
from loose dirt and foreign matter that may clog the heat exchanger.
4. Do not locate the condenser in the vicinity of steam, hot air, or fume exhausts.
5. Do not locate the condenser closer than 450mm from a wall, obstruction or
adjacent unit.
6. Avoid areas where heavy snow will accumulate at air inlet and discharge
locations.
7. Install a solid base capable of supporting the weight of the condenser. The base
should be at least 50mm higher than the surrounding ground and 50mm larger than
the dimensions of the condenser base, as shown in Figure 2-9.
2.5.2 Installation Procedure
1. Uncrate the condenser and place it onto the base.
2. Secure the condenser with expansive bolts. The installation sizes are shown in
Figure 2-8.

2.6 Piping Connections
2.6.1 General Principle For Piping
1. Use copper pipes to connect the evaporator and the condenser. Connections are
quick screw thread connections. If the line is too long and straight copper line is
used, piping joints must be brazed.
2. Follow standard industry procedures in selection and placement of pipe supports,
system evacuation and charging with refrigerant (only when pipeline is very long).
The standard refrigerant of this system is R22.
3. Give considerations to pipeline pressure drop, oil return to the compressor,
avoidance of oil logging in parts of the system and minimization of noise and
vibration.
4. Consult the factory if the equivalent length exceeds 50m, or if the vertical
difference between the evaporator and condenser exceeds the values in Table 2-3.
5. The recommend values in Table 2-3 are equivalent length. The loss of resistance
caused by elbows and valves has been taken into consideration. The installer
should confirm if these values are appropriate for site conditions.
