INSTALLATION & PREPARATION
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 recom-
mended that a water softener be used to prevent the possibility of
excessive 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 pro-
vides 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". 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". 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.
