WARNING
17.
Only use the supplied or specified installation parts. Else, it may causes Mono bloc unit vibrate, fall, water leakage, electrical shock or
fire.
18.
Install at a flat, strong and firm location which is able to withstand the Mono bloc unit’s weight. If the location is slanting, or strength is
not enough the set will fall and cause injury.
19.
Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will
cause fire or electrical shock.
20.
This equipment is strongly recommended to be installed with Residual Current Device (RCD) on-site according to the respective
national wiring rules or country-specific safety measures in terms of residual current.
21.
The unit is only for use in a closed water system. Utilization in an open water system may lead to excessive corrosion of the water
piping and risk of incubating bacteria colonies, particularly Legionella, in water.
22. If there is any doubt about the installation procedure or operation, always contact the authorized dealer for advice and information.
23. Select a location where in case of water leakage, the leakage will not cause damage to other properties.
24.
When installing electrical equipment at wooden building of metal lath or wire lath, in accordance with electrical facility standard, no
electrical contact between equipment and building is allowed. Insulator must be installed in between.
25.
This installation may be subjected to building regulation approval applicable to respective country that may require to notify the local
authority before installation.
26.
Any work carried out on the Mono bloc unit after removing any panel which is secured by screws, must be carried out under the
supervision of authorized dealer and licensed installation contractor.
27. Be aware that refrigerants may not contain an odour.
28.
This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and
telephone. Otherwise, it may cause electrical shock in case of equipment breakdown or insulation breakdown.
CAUTION
1.
Do not install the Mono bloc unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at
surrounding of the Mono bloc unit, it may cause fire.
2.
Do not release refrigerant during piping work for installation, re-installation and during repairing a refrigeration parts. Take care of the
liquid refrigerant, it may cause frostbite.
3.
Make sure the insulation of power supply cord does not contact hot part (i.e. refrigerant piping, water piping) to prevent from insulation
failure (melt).
4. Do not touch the sharp aluminium fin, sharp parts may cause injury.
5.
Do not apply excessive force to water pipes that may damage the pipes. If water leakage occurs, it will cause flooding and damage to
other properties.
6.
Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water leakage may happen and may
cause damage to properties of the user.
7.
The piping installation work must be flushed before the Mono bloc unit is connected to remove contaminants. Contaminants may
damage the Mono bloc unit components.
8.
Select an installation location which is easy for maintenance. Incorrect installation, service or repair of this Mono bloc unit may
increase the risk of rupture and this may result in loss damage or injury and/or property.
9. Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or fire.
10.
Power supply connection to Mono bloc unit.
Power supply point should be in easily accessible place for power disconnection in case of emergency.
Must follow local national wiring standard, regulation and this installation instruction.
Strongly recommended to make permanent connection to a circuit breaker. It must be a double pole switch with a minimum
3.0 mm gap.
-
Power Supply 1: Use approved 20A 4-poles circuit breaker with a minimum contact gap of 3.0mm.
-
Power Supply 2: Use approved 15/16A 2-poles circuit breaker with a minimum contact gap of 3.0mm. (Only applicable for
WH-MXC09J3E8) or
Use approved 20A 4-poles circuit breaker with a minimum contact gap of 3.0mm. (Only applicable for WH-MXC12J9E8,
WH-MXC16J9E8)
11. Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or fire.
12.
After installation, the installer is obliged to verify correct operation of the Mono bloc unit. Check the connection point for water leakage
during test run. If leakage occurs, it will cause damage to other properties.
13. Keep any required ventilation openings clear of obstruction.
14.
Installation work.
Four or more people are required to carry out the installation work. The weight of Mono bloc unit might cause injury if carried by less
than four people.
