This instruction sheet provides information for field installing an
HDS-1 Power Disconnect Switch in an HVH Series air heater.
ELECTRIC SHOCK HAZARD. Disconnect all power
before installing or servicing heater. Failure to do
so could result in personal injury or property damage. Power Disconnect Switch must be installed by
a qualified person in accordance with the National
Electrical Code, NFPA 70.
GENERAL
INSTALLATION
1. The amperage rating of the disconnect must be equal to or
greater than the amperage rating on Table A and as marked on
the nameplate located on the bottom access door (Figure 1).
A. The HDS-1 is rated 50 Amps at 480V or less and 40 Amps
at 500-600V. Verify that the volts and amps of the heater
(see heater nameplate) do not exceed the rating of the HDS-
1.
B. The power disconnect switch kit is to be installed in the five
(5) hole K.O. cluster located in the bottom left front corner
of the heater. The K.O.'s can be removed using a chisel or
similar tool, if the 7/32 Ø K.O.'s are stubborn, it may be
necessary to drill out using a 7/32 drill bit (See Figure 1).

INSTALLATION
Any installation involving electric heaters must be
performed by a qualified person and must be effectively grounded in accordance with the National
Electrical Code to eliminate shock hazard.
1. For easier wiring, it is recommended that the pigtail leads
from the disconnect switch be wired to the matching terminals
of the contactor or terminal block. It is also suggested that the
service entrance wiring be done at this time, terminal 1 and 3
for 1Ø and terminals 1, 3 and 5 for 3Ø (see Figure 3).
2. Insert switch through front of heater and secure in place with
the No. 8 screws.
3. Attach faceplate using the No. 6 screws. The "1" on the face
plate to face towards the louvers.
4. Slide handle on shaft of switch and fasten in place by tightening the pre-attached set screw.
5. Close cover and reattach screws.
