Fixing of Power Supply Cable and Connecting Cable
1. Connecting cable between Tank Unit and Outdoor Unit shall
be approved polychloroprene sheathed fl exible cord, type
designation 60245 IEC 57 or heavier cord. See below table for
cable size requirement.

•
Ensure the colour of wires of Outdoor Unit and the terminal no.
are the same to the Tank Unit respectively.
•
Earth wire shall be longer than the other wires as shown in the
fi gure for the electrical safety in case of the slipping out of the
cord from the Holder (Clamper).
2. An isolating device must be connected to the power supply cable.
•
Isolating device (disconnecting means) should have minimum
3.0 mm contact gap.
•
Connect the approved polychloroprene sheathed power supply
1 cord and power supply 2 cord and type designation 60245 IEC
57 or heavier cord to the terminal board, and to the other end of
the cord to isolating device (Disconnecting means). See below
table for cable size requirement.

(C) Pressure Relief Valve Drainage Pipework
•
Connect a drain hose to the Pressure Relief Valve hose outlet
h
.
•
The hose must be installed in a continuously downward direction
and left open to the frost-free atmosphere.
•
If drain hose is long, use a metal support fi xture along the way to
eliminate the wavy pattern of drain tube.
•
The water may drip from this discharge hose. Therefore must
guide the hose without close or block the outlet of the hose.
•
Do not insert this hose into
sewage hose or cleaning hose
that may generate ammonia gas,
sulphuric gas etc.
•
If necessary, use a hose clamp
to tighten the hose at drain hose
connector to prevent it from
leaking.
•
Guide the drain hose to outdoor as
illustrated at the right figure.
(D) Domestic Hot Water Tank Discharge (Drain Tap) and Safety
Relief Valve Pipework
•
Safety Relief Valve 0.8MPa (8 bars) incorporated in Domestic Hot
Water Tank.
•
Drain Tap and Safety Relief Valve discharge fittings share the
same drainage outlet.
•
Use R½” male connector for this drainage outlet connection (Tube
connector
g
).
•
Piping must always be installed in a continuously downward
direction. It must not be longer than 2m, with no more than 2 elbows,
and must not allow condensation to build up or freezing to occur.
•
The pipe from this drainage outlet fitting must not be shut off. The
discharge must be freed.
•
The end of this pipework must be in such a way so that the outlet is
visible and can not cause any damage. Keep away from electrical
components.
•
It is recommended to fit a tundish into this
g
pipework. Tundish
should be visible and positioned away from frost environment and
electrical components.
(E) Drain Elbow and Hose Installation
•
Fix the Drain Elbow

to the bottom of Drain
Water Hole
i
.
•
Use inner diameter 17 mm drain hose in the market.
•
This hose must to be installed in a continuously downward
direction and in a frost-free environment. Improper drain piping
may cause water leakage hence damage the furnitures.
•
Guides this hose outlet to outdoor only.
•
Do not insert this hose into sewage or drain pipe that may
generate ammonia gas, sulphuric gas, etc.
•
If necessary, use hose clamp to further tighten the hose at drain
hose connector to prevent leakage.
•
Water will drip from this hose, therefore the outlet of this hose must
be installed in an area where the outlet cannot become blocked.
