Good sample
P lace the unit on the rack
and piping work is done below
the unit. Bad sample
Service space is not enough,
because pipe runs near the
service panel.
N otes
() Be sure to fix the unit with anchor bolts
() Be sure to keep space above the unit at least m
() The connection of water pipes (Feed water inlet, Hot water outlet, Drain water outlet) should be done on site locally.
The heat insulator thickness of the water plumbing assumes it 0mm, And the racking covers are less than 00mm outside
diameter, and, please do it with circumference mm or less.
When they are more than circumference mm, Racking cover dimensions cannot remove a service panel after racking
construction more than 00mm outside diameter.
() The holes for power cable inlet, and connection wire outlet from heat pump water heater to cylinder unit are half-blanked.
Therefore please punch out the hole by cutting the residual portion and use it.
() For fixing the unit, the hole (Symbol F) for anchor bolts (M0 x ) can be used.
() In heavy snow region, please take following measures in order for the air inlet/outlet port and the bottom part of unit not to
be covered with snow
①
P lace the unit on the rack in order to make the bottom of unit higher than the snow surface.
②
Install a snow prevention hood (locally prepared according to the drawing provided by MHI) on the outlet port of the unit.
③
Install the unit at the space under the eaves or the snow prevention roof (locally prepared)
() If ambient temp becomes below 0º C, it may cause break of water pipes and damage on the unit due to freezing
Be sure to apply anti-freezing heater to feed water piping , hot water piping, drain water piping and drainage course in order
to prevent from freezing.
() Be sure to keep enough service spaces of more than 00mm in front of the unit service panel for easy inspection of the unit
and replacement of components.
When piping work is done, be sure not to interfere the pipes with the unit service space.
If the service space cannot be kept, please install the piping below the unit by placing the unit on the rack.
(Refer to following sample)
() The drain water is drained away from symbol H as well as symbol G.
P lease secure a drainage course about the drainage from symbol H.
(*) Be sure to keep more than 00mm spaces
when the unit contacts with a wall.
If the unit installed in succession,
0mm spaces is enough.
