unit;
3）If there are no reserving holes, the holes can be drilled, but it is not allowed to drill on the
spandrel girder or load bearing wall.
4）Pipelines for cooling water, hot water and return pipe should be prearranged, and should
reserve interfaces for the pipelines of cooling water, hot water and return pipe;
5）The indoor hot water pipelines should be kept in good heat insulation.
6）Reserve special route for water heater, type of power source and electric capacity should
satisfy the using requirements;
7）Check if the power cord and air switch satisfy the requirement of unit, whether they comply
with local safety criterion and law;
8）Check if the regional power supply quality (including voltage pulsation and interference
wave) can satisfy the requirements of local safety criterion and law; if not, please coordinate and
solve the problem.
2.2 On-site Examination and Verification of Design Draft
Installation personnel should carefully read the designing plan and draft provided by designer,
and conduct verification and examination according to on-site conditions, and propose reasonable
revised suggestion in time.
Confirmation sheet of construction design draft for examination and verification:
No.
Contents for Confirmation
Result
1
Check if the installation position of unit has satisfied the space requirement for
heat exchanger and maintenance
2
