RECEIVING EQUIPMENT
On receipt of the equipment, visually check for exter-
nal damage to the carton or the shipping crate. If the
carton or shipping crate is damaged, make a note on
the Bill of Lading and report the damage to the Carrier
immediately. Remove the heater from the carton or the

Do NOT use the shipping crate base as an installation
base. On occasion, items are shipped loose. Be sure
that you receive the number of packages indicated on
the Bill of Lading.
When ordering parts, you must specify Model and

Raypak recommends that this manual be reviewed

answer, please contact the factory or your local
Raypak representative.
Claims for shortages and damages must be filed with
carrier by consignee. Permission to return goods must
be factory-authorized and are subject to a stocking
charge.
Purchased parts are subject to replacement only
under the manufacturer's warranty. Debits for defec-
tive replacement parts will not be accepted and will be
replaced in kind only per our standard warranties.
Model Identification
The model identification number and the heater serial
number are found on the heater data plate. The model
number will have the form WH1-0514A or similar
depending on the heater model. (WH = Hot Water
Supply System, 1 = on/off firing, 0514 = size of
heater).
Rated inputs are suitable for up to 2000 feet elevation.
For elevations above 2000 feet, reduce input 4% for
each 1000 feet above sea level.
Time/Temperature
Relationships in Scalds
The temperature of the water in the storage tank
heater can be regulated by setting the temperature
dial on front of the tankstat. To comply with safety reg-
ulations, the tankstat was set at its lowest setting
before shipment from the factory.
Fig. 1 illustrates a mechanical tankstat. To adjust the
water temperature, insert a small straight screwdriver
into slotted screw in hole in front of tankstat and turn
wheel to desired setting. Thermostat is adjustable up
to 190°F.

DANGER:
There is a Hot Water SCALD Potential if
the tankstat is set too high.
CAUTION:
Hotter water increases the risk of
SCALDING!
NOTE:
When this heater is supplying general
purpose hot water requirements for use by
individuals, a thermostatically controlled mixing
valve for reducing point of use water temperature is
recommended to reduce the risk of scald injury.
Contact a licensed plumber or the local plumbing
authority for further information.
WARNING:
Pump motors should NOT be
supported by any type of stand or support from
above due to possible misalignment of pump and
motor which might occur.
