SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS

ELECTRICAL CONNECTIONS

WATER SUPPLY CONNECTION: Ensure that you have read

the section entitled “PLUMBING THE DISHMACHINE” above

before proceeding. Cold water supply must be a minimum of

70°F with a capacity of 180 gallons per hour at 8-12 PSI flow

to the glasswasher. Hot water supply must be a minimum of

130°F with a capacity of 10 gallons per hour at 20±5 PSI flow

pressure. Incoming hot and cold water service connection

(supplied by customer) must be a 1/2” pipe size minimum with

shut off valve. Install the water supply line (1/2” pipe size min-

imum) to the dishmachine using copper pipe. It is recom-

mended that a water shut-off valve be installed in the water

line between the main supply and the machine to allow access

for service.

In areas where the water pressure fluctuates or is greater than

the recommended pressure, it is suggested that a water pres-

sure regulator be installed.

Do not confuse static pressure with flow pressure. Static pres-

sure is the line pressure in a “no flow” condition (all valves and

services are closed). Flow pressure is the pressure in the fill

line when the fill valve is opened during the cycle.

It is also recommended that shock absorbers (not supplied

with the Delta 1200 units) be installed in the incoming water

lines. This prevents line hammer (hydraulic shock), induced

by the solenoid valves as they operate, from causing damage

to the equipment.

PLUMBING CHECK: Slowly turn on the water supply to the

machine after the incoming fill line and the drain line have

been installed. Check for any leaks and repair as required. All

leaks must be repaired prior to placing the machine in opera-

tion.

ELECTRICAL POWER CONNECTION: Electrical and

grounding connections must comply with the applicable por-

tions of the National Electrical Code ANSI/NFPA 70 (latest edi-

tion) and/or other electrical codes. Disconnect electrical

power supply and place a tag at the disconnect switch to indi-

cate that you are working on the circuit.

The dishmachine data plate is located on the right side of the

door. Refer to the data plate for machine operating require-

ments, machine voltage, total amperage load and serial num-

ber.

To install the incoming power lines, remove the electrical box

cover. This will require taking a phillipshead screwdriver and

removing the two (2) screws at the bottom corners and lift up

and off. Let the cover rest against the plumbing assembly.

Install conduit from the underside of machine to hole in rear of

electrical box below terminal block and ground lug. Install the

service wires (L1 & L2) to the appropriate terminals as they

are marked on the terminal block. Install the grounding wire

into the lug provided. Tighten the connections. It is recom-

mended that “DE-OX” or another similar anti-oxidation agent

be used on all power connections.

VOLTAGE CHECK: Ensure that the power switch is in the

OFF position and apply power to the dishmachine. Check the

incoming power at the terminal block and ensure it corre-

sponds to the voltage listed on the data plate. If not, contact a

qualified service agency to examine the problem. Do not run

the dishmachine if the voltage is too high or too low. Shut off

the service breaker and mark it as being for the dishmachine.

Advise all proper personnel of any problems and of the loca-

tion of the service breaker. Replace the electrical box cover

and tighten down the screws.
