Caution:
Be very careful when carrying the product.
- Do not have only one person to carry product if it is more than 20 kg.
- PP bands are used to pack some products. Do not use them as a mean for transportation because they are dangerous.
- Tear plastic packaging bag and scrap it so that children cannot play with it. Otherwise plastic packaging bag may suffocate children to death.
- When carrying the heat source unit, be sure to support it at four points. Carrying with 3-point support may make the heat source unit unstable, resulting in it falling.
6. Installation of unit and service space
6.1. Installation
•
Using the anchoring holes shown below, firmly bolt the unit to the base.
[Fig. 6.1.1] (P.2)
<A> Side-by-side installation
<B> Back-to-back installation
A Heat exchanger unit
C 4-ø14 (Anchoring hole)
*1
Select an installation site that is level and free from vibrations so that the side
panels of the units do not rub against each other.
*2
Select an installation site that allows the fixation of the units to the floor.
Bases and anti-vibration
•
Be sure to install unit in a place strong enough to withstand its weight. If the
base is unstable, reinforce with a concrete base.
•
The unit must be anchored on a level surface. Use a level to check after
installation.
•
Anti-vibration pads must be placed under the base of the unit.
•
If the unit is installed near a room where noise is a problem, using an anti-
vibration stand on the base of the unit is recommended.
[Fig. 6.1.2] (P.2)
E Anti-vibration pad etc.
Warning:
•
Be sure to install unit in a place strong enough to withstand its weight.
Any lack of strength may cause unit to fall down, resulting in a personal
injury.
•
Have installation work in order to protect against earthquake.
Any installation deficiency may cause unit to fall down, resulting in a
personal injury.
•
In the case of a side-by-side installation of a compressor unit and a heat
exchanger unit, leave a space of at least 10 mm between them.
When they are installed too closely together, they may rub against each
other and generate noise.
•
In the case of a back-to-back installation of a compressor unit and a heat
exchanger unit, leave a space of at least 50 mm between them.
If they are installed to closely together, there may not be enough space
for using the tools to anchor the units to the base.
