LAZER BOILING WATER UNIT
INSTALLATION AND OWNERS GUIDE
Thank you for choosing our Lazer Boiling Water Unit. Please take a few minutes to read this booklet because it contains important information about the correct installation and operation of your Lazer unit.
1. 
WARNING:
This Lazer unit produces boiling water (third degree burns may occur) and care should be taken at all times when using it. This unit is not intended for use by infirm persons and young children should be supervised to ensure that they do not play with the unit.
2. WATER QUALITY
Caution is suggested if the Boiling Water Unit is to be connected to a water supply with a high content of silica or calcium. Water supplies of this nature may be detrimental to the unit’s operation and may cause the warranty to become void. For further information relating to the guidelines of water quality, contact your local Rheem office for advice.
3. INSTALLATION
This boiling water unit shall be installed by a qualified service person. The installation must comply with AS/NZS 3500.4 and all relevant statutory and local body requirements of the state in which the Boiling Water Unit is installed.
A. LOCATION
This unit is designed for interior installation only.
B. OPENING THE UNIT
To remove the jacket from models 3, 5,
7.5& 10 L remove the 4 retaining screws at the top and bottom and pull the jacket forward. For models 15, 25 and 40 L unscrew the lid at the top and service plate on the left hand side.
C. MINIMUM CLEARANCES
For ventilation reasons, all units require a minimum clearance of 50mm on all sides. For ease of servicing (where there is sufficient space) we recommend 300mm clearance from the top of all units. For element replacement reasons we recommend clearance of 150mm from the right hand side of 3 to 10 litre units and 300mm from the left hand side of the 15 to 40 litre units.
D. MOUNTING
The Lazer when installed is suspended from mounting screws located into keyhole slots at the back of the unit (refer to the Mounting Dimension Specification on page 6).
Be sure that the mounting screws are securely inserted into the keyhole slots. The screws MUST be anchored in such a way, that they will hold the weight of the unit when filled with water, (refer to the specification table on page 5).
WARNING:
Before drilling into the wall make sure that the screw positions avoid any
E. WATER SUPPLY CONNECTION
Cold mains pressure water (refer to specification table on page 5 for minimum water pressures) must be piped and connected to the ½” BSP inlet fitting located on the left hand side underneath the unit. An accessible isolating valve must be installed near the unit.
This unit contains an inlet strainer on the water inlet connection (refer to figure 1). To ensure continuing satisfactory operation, it is suggested that the inlet strainer be serviced every six months by a qualified service person. Where poor water quality is present it is recommended to install an additional auxiliary filter.
