3. Connect one end of the water supply hose to the float tank inlet and connect
the other end to the pressurized water supply.
NOTE: If there is a high mineral content in your water, it is recommend-
ed that a water softener be used to prevent the possibility of exces-
sive scale buildup inside the heat exchanger coil.
4. Follow the incoming water requirements listed below:
a. Water pressure must be between a minimum of 40 PSI and a maximum
of 65 PSI.
b. Incoming GPM must be approximately one gallon more per minute than
the outgoing GPM stated on the machine nameplate. (You can check
the GPM of your source by timing the filling of a 5 gallon container.)
c. Incoming water temperature must not exceed 125°F. Excessive pump
damage may result if the water temperature exceeds this level.
5. Never allow the unit to operate without the incoming water line attached
and the water supply completely turned on.
UNLOADER:
The unloader has been preset at the factory.
GENERATOR:
This unit is equipped with a 115 Volt AC generator. The generator provides
power to the burner, and the control and safety circuits of the machine.
1. Always ensure the burner switch is in the OFF position before starting the
engine. Allow the engine to reach full RPM before turning the burner switch
to the ON position. Failure to do so can damage the generator or burner.
2. Do not spray water at or around generator. Electrocution and/or damage
to the generator, burner, and any auxiliary equipment may result.
PRE-START INSPECTION PROCEDURES:
Before starting the unit, perform the following procedures:
1. Check the oil level in the pump.
2. Inspect the water inlet strainer. Clean or replace if necessary. See "Water
Supply".
3. Check all hose connections to ensure they are securely tightened.
4. Inspect for system water leaks, oil leaks and fuel leaks. If a fuel leak is
found, DO NOT START UNIT! See "Risk of Explosion or Fire" warnings. Be
sure that all damaged parts are replaced and that the mechanical problems
are corrected prior to operation of the unit. If you require service, contact
Customer Service.
5. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or leak is
found, DO NOT USE HOSE! Replace hose before starting unit. See "Risk
of Injection" warnings. Be sure that all damaged parts are replaced and
that the mechanical problems are corrected prior to operation of the unit.
If you require service, contact Customer Service.
