Solenoid Valve Kit for 3-pipe ECOi systems
(CZ-P160HR3) for R410A
3-5. Installing the Solenoid Valve Kit (SVK)
1. For safe installation and trouble-free operation you must:
●
Carefully read these instructions before beginning.
●
Follow each installation step exactly as shown.
●
Observe all local, state, and national electrical codes.
●
Pay close attention to all warning and caution notices given
in these instructions.
2. Positioning for installation
●
The solenoid valve kit must be installed at a location within
30 m of the indoor unit.
However, the length of wiring provided with the solenoid
valve kit is 5 m. If the valve will be used with wiring that
exceeds 5 m in length, use a terminal box (field supply) or
similar device to extend the wiring. Refer to “Wiring, Tubing,
and Heat Insulation” within this section.
●
The solenoid valve kit produces some refrigerant noise. If it
is to be installed in a quiet place such as a hospital, library
or hotel, it is recommended that the solenoid valve kit be
installed in the ceiling of a corridor etc. apart from the room.
●
The solenoid valve kit must be located not less than 2.5 m
above the floor so that it cannot be touched.

●
Be sure to secure the solenoid valve kit with the hanging
bolts not to cause any falling damage, using the hanging
hooks.
Do not place the solenoid valve kit directly on the ceiling
surface. Select a location where the ceiling is strong enough
to support the weight of the solenoid valve kit. When
installing the solenoid valve kit, remember to install it with
the top surface facing upward. (See the figure shown in
the subsection “How to use the fittings” in the section “Valve
DimensionsandHangingMethod.”)
●
When installing the valve body, install it with the top surface
facing up. Secure 200 mm or more of space to the front and
150 mm of space upward so that the service panel can be
removed upward.
●
Never conduct drilling or welding on the sheet metal.
Place the solenoid valve kit so that it does not hinder
draining.
●
Donotcoverairholes.
