Checkup After Installation; Freeze Prevention Device; Checks Before Trial Operation; Checking For Gas And Water Leaks - Saturn KDB - 161 GOM Manual

1. Checkup after installation

1) Check the flammability and rigidity of floor & wall materials. Ensure that all-minimum clearances to walls, ceilings,
overhangs, etc. have been met.

2) Freeze Prevention Device

The units must be wired-in to AC 220 volt electrical circuit once they have been connected to water piping and the
circuit has been filled with water. If the freeze prevention circuit starts due to a low-water condition, the pump will
begin running on "air" and cause premature failure and will void the warranty on the pump.
Check to see if the unit is properly connected and the piping is insulated properly.
If the insulation has worn off or is not fitted, the risk of freezing of piping and severe damage to the unit is
considerable. Thoroughly check the piping insulation and replace where necessary.
Measures to prevent fire must be taken and check that flue ducts are installed in compliance with the instructions?

2. Checking for gas and water leaks

Are there any water leaks in the heating and domestic hot water piping?
Are there any gas leaks in the gas piping?

3. Checks before trial operation

Type of gas being supplied(the one indicated on the rating plate of the units)
When the type of gas does not match the one specified on the unit rating plate, modification and re-adjusting will
be required(Consult your heating dealer or a qualified technician with the gas utility company).
Test for leakage at all gas piping connections.
Inspect for proper operation of gas alarm system.
AC 220 volts 15 Amp. dedicated circuit with approved grounded connection.
Heating and hot water pipes must be properly installed and in compliance with the standard installation methods
and local code requirements.
in the unit.
Completely vent the air at this time.
Check DIP switch setting against the factory settings shown on the control board diagram.
Connect room thermostat and check all wiring connections at control, at molex connectors in unit and at main
circuit panel.
CAUTION! : Any air remaining in the heat exchanger piping will cause rapid corrosion
