(3) The unit shall be installed securely. When installing hanger bolts, be sure they are capable of
withstanding 4 times the weight of the unit. If unsure, they shall be reinforced. The weight of
the unit is specified on the nameplate.
(4) Enough service space shall be left around the unit as shown in the figure below.
>0.3m
>0.25m
(5)
The drain pan shall tilt toward the drain outlet with a desired downward slope. Hanger bolts are
only intended to bear the weight of the unit other than the outside force of the duct, water pipe
and others.
(6) The length of the duct shall be compatible with the rated static pressure, otherwise the unit
would fail to run properly. The inlet and outlet of the duct shall be attached with flexible
connections.
(7) Water pipes shall be cleaned up prior to installation, and the outlet shall be equipped with a
filter to prevent valves from being clogged by foreign matters.
(8)
The unit shall be protected again dust during installation.
(9)
A filter shall be installed at the return air inlet and be cleaned frequently to guarantee the
expected heat exchange efficiency.
(10)
The duct shall comply with requirements stated below.
1)
The duct shall be designed and installed as per the applicable local standards.
2) The duct shall be designed so that its sectional area won’t change suddenly and the air
direction won’t change at the outlet.
3) The duct shall be insulated reliably to prevent sweating under the cooling operation.
(11)
Water pipes shall comply with requirements stated below.
(12)
The drain pipe and inlet/outlet pipe shall be with the standard threaded pipe fittings. Water
pipes shall be installed as per applicable local standards. During installation, do not over-
tighten the pipe fittings to avoid any damage on the header and connections of the coil.
1) The inlet/outlet pipe shall be installed in accordance with the applicable labels and equipped
with the quakeproof flexible connections and movable joints, as well as suitable filters
to prevent the heat exchanger from scaling which then would lower the heat exchange
efficiency.
2)
The inlet/outlet pipe shall be equipped with valves to control and cut off the water flow. The
weight of water pipes shall not be withstood by the main unit.
3) The inlet/outlet pipe, drain pipe and valves shall be insulated to prevent sweating under the
cooling operation in summer.
4) The condensate drain pipe should be installed downward with a slope larger than 5% to
facilitate drainage.
5)
Do not drag and pull water pipes forcibly and seal them with Teflon tape to avoid water
leakage.
(13) Be sure the power supply coincides with that specified on the nameplate and is cut off prior
to electric installation. Electric wiring shall be performed in accordance with the electric wiring
diagram as shown the figure below and the unit shall be grounded reliably. The appliance shall
be installed in accordance with national wiring regulations.
(14) The power cord technical data we recommended is 0.5*3(Unit:mm
2
*ROT).
(15)
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.
(16) Means for disconnection must be incorporated in the fixed wiring in accordance with the wiring
rules.
(17)
The appliance is intended to be permanently connected to the water mains and not connected
by a hose-set.
