Installation process:
Preparation before installation:
one Data preparation
Air conditioner installer: air conditioner drawings and design scheme.
Decoration party: decoration drawings and scheme.
Property management party: building structure drawings, power distribution quota.
two Communication
Communication participants: users (or user representatives), air conditioner installation parties, decoration parties, property management parties, etc.
Communication content: determine the installation position of outdoor unit and indoor unit; Determine the layout trend of water pipe and copper pipe; Determine the layout direction of power line and communication line; Determine the position of air supply outlet, air return outlet and access hole. Confirm that the household power quota meets the unit power requirements; Confirm that the air supply and return ports are not blocked by lamp slots, and the air supply and return ports are not short circuited; Confirm that the access hole is not blocked, which can facilitate the maintenance of the unit; Confirm the position of heavy wall, heavy beam, etc.
Power cord routing:
one Conditions for construction: the installation position of the unit has been determined.
two Construction time: decoration and wiring.
three Specific construction cooperation:
one ）Therefore, this work is part of the indoor power supply layout, and priority should be given to the decoration unit through communication with users.
two ）Determine the power wire diameter according to the unit power parameters, inform the decoration unit, and supervise the construction process.
three ）The wiring requires that the air conditioning power supply is independent, and all indoor and outdoor units in each system supply power uniformly.
four ）The power line shall be embedded near all air conditioning units, and sufficient wiring length shall be reserved.
Communication line wiring:
one Conditions required for construction: the installation position of the unit has been determined, and the position of the wire controller has been determined
two Construction time: decoration and wiring
three Specific construction cooperation:
one ）For this item, priority should be given to the decoration unit for construction through communication with users. If the decoration unit disagrees, it should choose to construct by itself.
two ）According to the requirements of the unit, determine the specification and diameter of the communication line, inform the decoration unit, and supervise the construction process.
three ）The communication line shall not be laid with the power line at the same time, at least 150mm 。
four ）The communication line shall be embedded near all air conditioning units and wire controllers, and sufficient wiring length shall be reserved.
example:
Indoor unit installation:
one Construction conditions: indoor painting has been completed
two Construction time: before ceiling installation
three Specific construction cooperation:
one ）The indoor unit shall be hoisted correctly according to the previously determined unit position and air outlet position without deviation.
two ）After the hoisting of the unit is completed, the decoration unit shall be informed of the location and size of the air outlet opening, and the relevant information signs can be pasted on the unit, as shown in the following figure.
Copper pipe laying and installation:
one Construction conditions: indoor painting has been completed
two Construction time: before ceiling installation
three Specific construction cooperation:
one ）The copper pipe shall be arranged as close to the wall as possible, and the interference with decoration can be avoided if the space occupied is small.
two ）The copper pipe shall be arranged to avoid the heavy beam as far as possible. If it is impossible to bypass the heavy beam, the pipe shall be laid under the beam first. Otherwise, the pipe can be drilled on the beam only after the user's written consent is obtained and the user is willing to bear the consequences caused by drilling on the beam.
three ）During the copper pipe layout, the pipe orifice shall be protected from dust and impurities, and the decoration unit shall be informed not to damage the copper pipe to avoid the nail gun hitting the copper pipe.
four ）When maintaining the pressure of copper pipe, the decoration unit shall be informed not to touch the copper pipe to avoid danger.
five ）After the installation of copper pipes, the decoration unit shall be informed not to change the layout of movable copper pipes. Installation of condensate drain pipe:
one Construction conditions: indoor painting has been completed
two Construction time: before ceiling installation
three Specific construction cooperation:
one ）The condensate drain pipe shall be arranged as close to the wall as possible.
two ）The arrangement of condensate drain pipe shall avoid heavy beam as far as possible.
three ）After the installation of the condensate drain pipe, the decoration unit should be informed not to let the nail gun hit the water pipe, not to change the layout of the mobile pipeline, not to raise the water pipe, but to make a sign reminder, as shown in the following figure.
Outdoor unit installation:
one Conditions for construction: the location of outdoor unit has been determined.
two Construction time: when there is sufficient passage space before the anti-theft net is installed.
three Specific construction cooperation:
one ）Basically unrelated to the indoor decoration, users and decoration units need to be reminded that if the anti-theft net is installed, an openable door must be reserved to facilitate the subsequent maintenance of the outdoor unit. It cannot be completely sealed.
Installation of air outlet and manhole:
one Construction conditions: installation of indoor unit and ceiling is completed
two Construction time: when the ceiling is completed and holes have been opened
three Specific construction cooperation:
one ）Before the construction of partial suspended ceiling, the position and size of air outlet and manhole opening shall be confirmed to the decoration unit again.
two ）Confirm whether the opening position and size are correct and whether the tuyere is covered by the light slot before the installation of the tuyere and access door. If not, report and negotiate with the user and ask the decoration unit to modify; Ensure that the supply and return air are unobstructed and there is no short circuit of supply and return air, and the access port is convenient for maintenance and operation.
three ）When installing air vents and access openings, ask the user whether there will be installation of wardrobe and other furniture in the future. If there is, remind the user to avoid air vents and access openings during installation.
Commissioning acceptance:
one After the installation of air conditioners is completed and the decoration is basically completed, power can be transmitted for the commissioning and acceptance of air conditioning units.
two During commissioning and acceptance, if there is still a problem of blocking the air outlet and access port, and the user and decoration unit have communicated on relevant matters in the early stage, if the negotiation fails, the fact and adverse consequences must be specifically stated on the commissioning and acceptance sheet, and all parties must sign to confirm the filing, so as to avoid subsequent disputes.
