Installing the product
1-
Transport the water heater to the place where it is to be installed.
2-
Cut the cardboard skirting along the dotted lines.
3-
Take the water heater off the pallet and place it by the hydraulic connection.
MAXIMUM!
The water heater must be installed on a smooth and horizontal
floor.
If this is not the case, it must be
levelled
using the supporting feet.
If this precaution is not taken, problems may occur evacuating the
condensates, resulting in frosting.
In accordance with AS/NZS
60335.2.21 the water heaters
must be fixed to the ground
using the attachment provided
and in compliance with the New
Zealand Building Code Clause
G12, Seismic restraint of
storage water heaters.
The clearance required needs to be adequate for service/replacement of cold water inlet piping devices,
PTR valve and tempering valves (where fitted), elements and thermostats. This may be facilitated by
correct orientation of the cover positions when installing. There are no operational clearance limitations to
surrounding structure. PTR valve removal requires approximately 150 mm for withdrawal.
AS/NZS 3500.4 – National plumbing & drainage. Hot Water Supply Systems – Acceptable solutions.
Combustible Material :
It is recommended to not place combustible material on or adjacent to the water heater.
Internal Installation Safe Tray :
For internal (inside home) installations, a safe tray is recommended in accordance with AS/NZS 3500.4.
Hydraulic connection
Cold water inlet
Before making the hydraulic connection, it is essential to clean the feed pipes thoroughly to avoid the risk
of metal or other particles entering the tank or the water heater.
Cold water piping should be provided with a 500 – 560 kPa Pressure Limiting Valve at the point of cold
water connection to the water heater. In addition to the Pressure Limiting Valve, it is a requirement of AS
3500.4 & NZBC G12 that both a Stop Valve and a Non Return Valve are installed upstream of the Product.
No parts (stop valve, pressure reducer, etc.) must be placed between the pressure limiting
valve and the cold water inlet of the water heater, apart from a copper pipe.
Note: since limited water discharge from pressure limiting valve is normal in the heating operation, the
discharge pipe needs be connected to external drain.
