CAUTION

 

Make sure a suitable Teflon tape is used for all plumbing connections to prevent leakage.

 

Use only Nylon/ Stainless Steel (SS) braided hoses (Flexible Hoses) having a minimum 
pressure rating of 6 Bar and hoses should be compatible for hot water applications.

 

Water Heater must be mounted in vertical position only as shown in Installation Diagram.

 

Failure to follow this instruction can result in property damage.

Operation

Figure 11

1. Open a nearby hot water faucet to permit air to escape.
2. Open the cold water inlet valve completely and allow water to flow 

to the unit.

3. Close hot water faucet when water flows.
4. When all water connections are completed, check for leaks and 

take corrective action before operating.

Note: The minimum water flow to switch ON the unit is 1.8 L/min.

CAUTION

 

The Water Heater will not run unless there is a minimum water flow (1.8 L/min). Failure to do 
so may result in damage to the Water Heater and injuries to the user. This will also make the 
warranty null and void.

 

Once the Mounting and Plumbing is completed, then only the power supply should be 
switched ON.

 

Do not splash water directly or clean with benzene, pesticides, thinner, alcohol, etc., but use 
a soft, dry cloth to clean the Water Heater.
