WARNING:

When working on the machine, always dis­connect power to HT-25 and tag-out before
servicing. Heater will remain hot immedi­ately after emptying the wash tank. Turn
off machine at master switch before open­ing for inspection.

IMPORTANT:

HT-25 requires a 10-gauge neutral and
suitable ground. It is recommended that
new equipment be installed with new circuit

NOTE TO INSTALLER:

DO NOT INSTALL SPRAY ARMS UNTIL MACHINE IS
FLUSHED WITH WATER. Machine will automatically fi ll with

water and complete one cycle when power is turned on. This
will fl ush installation debris from tank and pump and prevent
damage to spray arm bearings. After fl ushing, empty the tank
by removing the pump fi lter and install both wash and rinse
spray arms.

Machine can be installed in corner or straight installations.
Make sure removable tray track guide (dishrack guide) is
aligned for installation. Verify that door lever arm clears
dishtable (7” needed for clearance). If necessary, notch
dishtable fl ap.

FOR YOUR SAFETY

Read and observe all CAUTIONS and WARNINGS
shown throughout these instructions. While
performing installations described in this booklet
APPROVED Personal Protective Equipment,
including SAFETY EYE-WEAR must be worn.

IMPORTANT - Dishmachine MUST be

installed to allow for servicing of motors and
booster (B-13). Do not install chemical
dispensers on the top of the control box or
dishmachine. If you receive a damaged dish­washer, immediately contact your dealer.

Optional Accessories -

Built-on Booster B-13 - Stainless Steel Built-

on Booster. Pre-plumbed with single connection
installation.

Hatco Booster C6 or C12 - Free standing

Booster in 3-phase or single phase. C-6 Booster is
40 degree rise and C-12 is 70 degree rise.

Electrical

Electrical HT-25 (3-phase with 10-gauge neutral)

The power supply (208 volt - 40 amps) must consist of three (3) eight-gauge wires of 50a capacity, ten-gauge wire of
40a capacity, and a suitable ground. The 40 amp breaker or fuse must be on a clean circuit to the machine. ADS has
provided a conduit hole (1 3/8” for 1” conduit) for electrical service in the back of the control box. Attach the eight-gauge
wires to the main distribution block (5 pole) in the control box, to terminals marked L1, L2, & L3. Attach the ten-gauge
neutral and ground wire to their proper terminal locations as marked on the main distribution block and tighten all wires.

240 Volt Delta System: If you have 240 volt, delta system, attach the high leg (200 volt line) to L3. Attach your 120 volt
wires to L1 and L2.

230-B Phase System: If you have 230-B phase power (230v, 230v, neutral), a separate 120 volt control circuit must
be supplied. The 120 volt, twelve to fourteen-gauge supply wires (black & white) must be attached to the connection
terminal (4 blades) located 1” under the main distibution block. This connection terminal is labeled, with a yellow decal,
marked 120 volt. Prior to connecting 120 volt supply wires, you will need to remove short, jumper wires (black and white)
that connect main distribution block to this terminal. Make sure that wires (also black and white) connecting master switch
to this conncetion terminal remain attached.

Remove front panel and check rotation of wash motor. A rotation arrow is provided on the motor. If motor is running in
reverse, turn off main power and switch incoming power wires on L1 & L2. Verify proper rotation and tighten all wires.

Caution: Before powering machine, check all screw terminals in control box. Screws can loosen in transit.

Loose connections on high load terminals will cause wire burning and component damage during machine op­eration and will not be covered under ADS warranty.

Electrical HT-25 (single-phase “DUAL” circuits with 10-gauge neutral)

ADS has provided two (2) conduit holes (1 3/8” for 1” conduit) for electrical service in the back of the control box.

Warning: Label building circuit breakers, noting DUAL supply to dishmachine.

Circuit One: The power supply (208 volt - 30 amps) must consist of a minimum of two (2) ten-gauge wires of 40a capacity
(eight-gauge wires are recommended for added service life), a ten-gauge neutral, and a suitable ground. Attach the two (2)
eight-gauge wires to the main distribution block (four poles) in the control box to terminals marked L1 & L2. Attach the ten­gauge neutral and the ground wire to their proper terminal locations as marked on the main distribution block.

Circuit Two: The wash heater is powered, on a separate circuit, using two (2) six-gauge wires of 75a capacity (208 volt -
60 amp). The 60 amp breaker or fuse must be on a clean circuit to the machine. Using the second conduit hole, attach the
wires to the wash heater distribution block (2 pole) and tighten both wires.

Caution: Before powering machine, check all screw terminals in control box. Screws can loosen in transit.

Loose connections on high load terminals will cause wire burning and component damage during machine
operation and will not be covered under ADS warranty.

Electrical HT-25 with built-on Booster (3-phase with 10-gauge neutral)

HT-25 with built-on booster cannot be installed using 230-B phase power (230, 230, neutral). For this voltage

free-standing booster must be utilized.

The power supply (208 volt - 50 amps) must consist of three (3) eight-gauge wires of 65a capacity, a ten-gauge neutral,
and a suitable ground. The 50 amp breaker or fuse must be on a clean circuit to the machine. ADS has provided a conduit
hole (1 3/8” for 1” conduit) for electrical service in the back of the control box. Attach the eight-gauge wires to the main
distribution block in the control box, to terminals marked L1, L2, & L3. Attach the ten-gauge neutral and ground wires, of
40a capacity to their proper terminal locations as marked on the main distribution block and tighten all wires.

240 volt Delta System: If you have 240 volt (delta system) attach the high leg (200 volt line) to terminal marked L3. Attach
your 120 volt, eight-gauge wires to terminals marked L1 & L2.

Remove front panel and check rotation of wash motor. A rotation arrow is provided on the motor. If motor is running in
reverse, turn off main power and switch incoming power on L1 & L2. Verify proper rotation and tighten all wires.

Caution: Before powering machine, check all screw terminals in control box. Screws can loosen in transit.

Loose connections on high load terminals will cause wire burning and component damage during machine
operation and will not be covered under ADS warranty.
