only Warranty, if a service agent cannot be found.
Responsibility for labor, in such instances will be
that of the consumer-owner. Equator Advanced
Appliances will, however provide free technical
assistance for repairs.
GENERAL
Since it is the responsibility of the consumer-owner
to establish the warranty period by verifying the
original purchase date, Equator Advanced

service call which does not involve defective
workmanship or materials will be the
responsibility of the consumer-owner.
In addition, the following work is not covered under
warranty and does not constitute warranty work:
• Installation - improper hook-up or leveling
• Maintenance - cleaning of air and/or water filter.
• Damage - replacing broken door handle Most work
is covered. The defining factor is, has the
machine malfunctioned (Equator is responsible)
or has the customer omitted or done something

SAFE SERVICING PRACTICES
To avoid the possibility of personal injury and/or
property damage, it is important that safe servicing
practices be observed. The following are examples,
but without limitation, of such practices:
1. Do not attempt a product repair if you have any
doubts as to your ability to complete it in a safe and
satisfactory manner.
2. Before servicing or moving an appliance:
• remove fuse.
• turn off gas supply.
• turn off water supply.
3. Never interfere with the proper operation of any
safety device.
4. USE ONLY REPLACEMENT PARTS CATALOGED
FOR THIS APPLIANCE. SUBSTITUTIONS MAY
DEFEAT COMPLIANCE WITH SAFETY STANDARDS
SET FOR HOME APPLIANCES.
5. GROUNDING: The standard color coding for safety
ground wires is GREEN or GREEN with YELLOW
STRIPES. Ground leads are not to be used as current
carrying conductors.
IT IS EXTREMELY IMPORTANT THAT THE SERVICE
TECHNICIAN RE-ESTABLISH ALL SAFETY GROUNDS
PRIOR TO COMPLETION OF SERVICE. FAILURE TO
DO SO WOULD CREATE A POTENTIAL HAZARD.
6. Prior to returning the product to service
ensure that:
•all electric, gas, and water connections are
correctly and securely connected.
•all gas and water connections are tested for
leaks. DO NOT TEST FOR GAS LEAKS WITH A
FLAME.
•all electrical leads are properly dressed and
secured away from sharp edges,
high-temperature components and moving
parts.
•all uninsulated electrical terminals,
connectors, heaters, etc. have adequate spacing
from all metal parts and panels.
•all safety grounds (both internal and external
to the product) are correctly and securely
connected.
•all panels are properly and securely
reassembled.
CAUTION! When servicing a water-using
appliance in a location where the water supply
has not been in use for an extended time (such
as vacation) open the hot water faucet at the
sink and allow the water to run for several
minutes allowing water and accumulated
hydrogen gas to escape. Make sure there are no
open flames (pilots) or cigarettes near the
faucet.
CAUTION
A lightning flash symbol, within a triangle. Is intended
to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a
risk of electric shock to persons.
CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK DO NOT REMOVE
COVER OR BACK. DO NOT EXPOSE TO
RAIN OR MOISTURE.
NO USER SERVICABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE
PERSONNEL.
An exclamation point within a triangle is intended to
alert the user to the presence of important operating
and maintenance (servicing) instructions in the
literature accompanying the appliance.
WARNING:
TO PREVENT FIRE OR SHOCK HAZARD, DO
NOT EXPOSE THIS PRODUCT TO RAIN OR
MOISTURE.

IMPORTANT PRESERVICE INSTRUCTIONS
►It is advisable for anyone to go through the following points before one actually works on the unit.
•Shipping Rods: The unit is shipped with 2 shipping rods and spacers to avoid any damage to the
unit during shipping. Make sure that all the shipping rods and the spacers have been removed from the
unit.
•Height of drain hose: The drain hose should be placed in such a way that the height of the drain
hose does not exceed 36” and is not lower than 28” inches from the bottom of the unit.
•Water inlets: In this unit two water inlets are required to be connected for hot as well as for cold
water(Note that Valves are Matrix Size & L Connector of the inlet hose supplied with the machine is also
Matrix. The straight connector is US Thread). Make sure that water supply is provided to both the inlets. In
case hot water supply is not available cold water supply should be connected to the hot water inlet valve.
•Leveling: The unit must be leveled properly for proper working of the unit. There are 4 leveling feet
which can be individually leveled.
•Flooring: The unit should be installed on strong and leveled floor, installation on carpet or wood
increases vibrations. In case of wooden flooring, proper bracings should be made and the unit should be
installed on a sheet of plywood.
※Please note: All the above instructions are mentioned in the Owner’s Manual
and if the unit is found to be malfunctioning due to any of the above points not
been taken care of, the customer will be liable to pay for the complete service
call along with the parts. If the customer is not willing to pay for the service we
will be paying for the same but the customers warranty will be voided then.

INSTALLATION (EZ 4000 CV)
Inlet Hoses
The inlet hoses must be fitted with the special rubber washers. These rubber washers ensure a water tight
seal between the hoses and the water inlet valves to prevent water leaks. Water should flow freely into the
machine, be sure that the inlet hoses are not bent or kinked.
Please read the following steps carefully (Fig.1, Fig.2)
1. Connect the straight end of the hot-water hose to the hot-water faucet (Fig.1).
2. Connect the straight end of the cold-water hose to the cold-water faucet (Fig.1).
4. Connect the L-shaped end of hot-water hose to the inlet valve which has a red strainer. (Or connect to
the pressure-reducing valve if necessary). (Fig.2).
5. Connect the L-shaped end of cold-water hose to the inlet valve which has a white strainer. (Or connect
to the pressure-reducing valve if necessary). (Fig.2).
Fig.1
Fig.2
Drain Hose
Connect the drain hose to a drain duct (with internal diameter of at least 1.6 inches) or place it for drainage
in to a sink or a tub, ensuring that there are no kinks or bends. The free end must be at a height of at least
24” from the floor (max 40”), the hose must be fixed in the appropriate hook on the upper part of the back
panel (see figure below).
U-Connector
The end of the outlet hose must be passed through the U-Connector (included). This creates an
upside-down U which is put into the drain pipe or over the edge of the sink. Failure to use the U-Connector
may cause the drain hose to pop-up during drainage of the water, which may cause water damage to the
surrounding area.

How to update the software?
1. Set the mode select switch to M2, and the power select switch to 5 on the MINICUBE2 unit.
2. Power off the washing machine, and unplug the communication cable from DP or EM.
3. Connect the laptop and MINICUBE2 using the USB cable. And connect the MINICUBE2 and DP or EM
using the target cable. The triangle mark on the target cable connector should be aligned with the
similar mark on the PCB of DP or EM (see figure below), in order to make sure to mate the connectors
