2.9 Unit Support Recommendations
Guidelines:
1. The base of the unit should be fully supported and not allow deection in static or dynamic loading
2. The supports should run perpendicular to the fork pockets on the base of the unit
3. The fork pockets should remain in place for best support
4. The supports should be 12” on center and include all outer edges
5. The unit should be mechanically fastened to the support platform to not allow independent movement
between the unit and its support

This is a recommendation as it relates to best practices for supporting the unit. Understand that how the unit
should be supported varies based on several factors such as available space, supporting structure (concrete,
metal), application (static or dynamic) etc. ICE recommends that the structural integrity of the design be evalu-
ated by a structural expert before integration into the design. Any decision on use of materials or geometry
are the sole responsibility of the customer. Please be advised that supporting the unit along the entire base is
required for proper logistics movement and in place operation.
2.10 Electrical Connections
WARNING ELECTRICAL SHOCK HAZARD
Failure to follow safety warnings exactly could result in serious injury, death, and/or
property damage.
Turn off electrical power at fuse box or service panel BEFORE making any electrical
connections and ensure a proper ground connection is made before connecting line
voltage.
Important
All electrical work must meet the requirements of local codes and ordinances. Work should be
done only by qualied persons.
The units may incorporate an internal crankcase heater for compressor protection. The crankcase
heater must be energized for at least 24 hours prior to starting the compressor.
Scroll compressors, like several other types of compressors, will only compress in one rotational direction.
The direction of rotation is not an issue with single-phase compressors since they will always start and
run in the proper direction. However, three phase compressors will rotate in either direction depending
upon phasing of power. Since there is a 50-50 chance of connecting power in such a way as to cause
rotation in the reverse direction, it is imperative to conrm that the compressor is rotating in the proper
direction at the initial eld start-up of the system. Verication of proper rotation is made by observing
