6. Installation considerations
(2) Installation location
!
Caution
1. Provide the required space for inspection and maintenance (see Figure 2).
Insuffi cient space at the installation location could result in accidents from falling equipment.
2. If the water heat exchanger unit is installed on a roof or other high location, provide a permanent ladder
or hand grips for safe access, and provide railings or hand grips around the water heat exchanger
unit to prevent falls.
3. Ensure that the installation location has adequate water drainage.
A defect in the piping could cause water leaks into the surrounding property.
• Drain pipes that pass indoors should be as short as possible.
• Drain pipes that pass indoors must be insulated.
• Make sure that drain water cannot cause trouble for surrounding properties.
4. Use a leveling tool to ensure that the unit is truly horizontal.
Water leaks can result if the unit is not horizontally true.
1. Avoid locations near equipment that emits high
frequency radiation.
2. When lifting the water heat exchanger unit by
suspension:
Suspend the unit by attaching ropes to the four
suspension rings on the base.
When attaching lifting ropes, protect the external
fi nish from scratches by, for example, using timber
battens.
When lifting by crane, make sure that the crane hook
is at least 1 m from the unit.
!
Caution
Do not lay the heat exchanger unit on its side
during transportation. Internal damage could result
in malfunction.
