THIS BOILING WATER UNIT IS FOR INDOOR INSTALLATON ONLY.
BOILING WATER UNIT LOCATION
The boiling water unit is suitable for indoor installation only. The boiling water
unit should be installed close to the most frequently used outlet and its position
chosen with noise, safety and service in mind. Ensure that the air vents are
clear of obstructions at all times. This boiling water unit is designed to fit under
a standard sink (internal cupboard depth of 550mm).
The boiling water unit should be positioned with the 24 hour timer facing the
front of the cupboard for easy viewing.
Clearance must be allowed for servicing of the boiling water unit. The installer
must leave at least 50mm clearance on sides that have vents to allow air flow
to critical components.
You must be able to read the information on the rating plate. Remember you
may have to remove the entire water heater for servicing.
The installation must comply with the requirements of AS/NZS 3500.1, AS/NZS
3500.2, AS/NZS 3500.4, AS/NZS 3500.5, AS/NZS 3000 and water supply by-
laws, relevant local authority by-laws, codes (eg Building Code) and regulatory
authority requirements. In New Zealand, the installation must conform to the
New Zealand Building Code.
The water heater must not be installed in an area with a corrosive atmosphere
where chemicals are stored or where aerosol propellants are released.
Remember the air may be safe to breathe, but the chemicals may attack the
materials used in the construction of the boiling water unit, or adversely affect
the operation of the boiling water unit.
MAINS WATER SUPPLY
Where the mains water supply pressure exceeds that shown in the table below,
an approved pressure limiting valve is required and should be fitted.

TANK WATER SUPPLY
If the boiling water unit is supplied with water from a tank supply and a
minimum water supply pressure of 100 kPa at the boiling water unit cannot be
achieved, then a pressure pump system must be installed to allow the boiling
water unit to operate. The cold water line from the supply tank should be
adequately sized and fitted with a full flow gate valve or ball valve, and care
must be taken to prevent water hammer occurring between the pump and
boiling water unit. Failure to comply could void the warranty.
