Onsite Review Of Design Drawing; Requirements For Cooperation With Civil Engineering; Requirements For Cooperation With Decoration Engineering; Requirements For Cooperation With Electric - Gree GMV-S120WL/A-S Service Manual

cooperation between different professions such as architecture, structure, electric, water supply
and drainage, fire-fighting, and decoration. Pipes must be laid in places away from any automatic
spray head for fire-fighting, and must be reasonably arranged to ensure that the pipes fit the
electric, luminaries, and decoration.

3.1.3.1 Requirements for cooperation with civil engineering:

1） The riser should be installed in the air conditioning tube well, and the horizontal pipe should
be placed in the ceiling, if possible.
2）A place should be reserved for the ODU base to prevent the waterproof layer or insulating
layer on the roof from being damaged in later phase of installation.
3）At places on walls or floors where pipes need to go through, holes or casing should be
preserved. If the pipe needs to go through a bearing beam, a steel casing must be prepared.

3.1.3.2 Requirements for cooperation with decoration engineering:

1）The air conditioning installation should not damage the bearing structure or the decorative
style. Air conditioning pipes should be laid out along the bottom of the beam as possible. If pipes
meet one another at the same elevation, process based on the following principles:
2）Air conditioning pipes should be laid out along the bottom of the beam as possible. If pipes
meet one another at the same elevation, process based on the following principles:
（1）Drain pipes, air ducts and pressure pipes should leave places for gravity pipes;
（2）Air ducts and small pipes should leave places for major pipes.

3.1.3.3 Requirements for cooperation with electric:

After the capacity of air conditioning unit is determined, check the following aspects with
relevant electric design personnel:
1）Whether the electrical load is designed based on the requirement of the air conditioning
unit;
2）Whether the power cable and circuit breaker meet the unit requirement and abide by
relevant national safety regulations;
3）Whether the regional power supply quality (including voltage fluctuation and interference
noise) meet the international requirement.
Any nonconformity must be resolved through coordination.

3.2 Onsite Review of Design Drawing

Installation personnel must carefully read and understand the design scheme and drawings
provided by engineering designers, and prepare detailed and feasible construction organization
design after reviewing the onsite status.
The following aspects of working drawing must be reviewed:
