RECEIVING THE AIR CONDITIONER

Inspect the air conditioner. Check for concealed damage that may have occurred during shipment. Look for dents,

scratches, loose assemblies, evidence of oil, etc. Damage evident upon receipt should be noted on the freight bill.

Damage should be brought to the attention of the delivering carrier -- NOT to nVent Equipment Protection -- within

15 days of delivery. Save the carton and packing material and request an inspection. ��

claim with the

delivering carrier.
nVent Equipment Protection cannot accept responsibility for freight damages; however, we will assist you in any

way possible.

HANDLING AND TESTING THE AIR CONDITIONER

If the air conditioner has been in a horizontal position, be certain it is placed in an upright, vertical or mounting

position for a minimum ��

e (5) minutes before operating.

Do not attempt to operate the air conditioner while it is horizontal

or on its side, back or front. The refrigeration compressor ��

with lubricating oil. This will cause permanent damage to the air

conditioner and also voids the warranty.

CAUTION

TEST FOR FUNCTIONALITY BEFORE MOUNTING THE AIR CONDITIONER TO THE ENCLOSURE.
Refer to the nameplate for proper electrical current requirements, and then wire the unit to a properly grounded

power supply using copper conductors only. Power supply wiring should be restr��

installation to

ensure no contact with internal fan. Minimum circuit ampacity should be at least 125% of the amperage shown

on the unit nameplate. No other equipment should be connected to this circuit to prevent overloading.
Electrical circuit should be fused with slow blow or heating, air conditioning and refrigeration (HACR) rated circuit

breaker. Use a higher ampere rated circuit breaker or time-delay fuse that is closest to the nominal ampere rating

of the air conditioner, or sum of the individual component ampere ratings, to protect system electrical circuits

from short circuit or overload.

PHASE MONITOR (460V ONLY)

Note Location: Rear access panel, D-shaped sight port.

This product is equipped with Phase/Voltage Protection. Please verify correct phasing and voltage before

operating. Note the fans may still operate if phasing is incorrect, but the compressor will not, so the unit

will not cool. Illuminated light on Phase Monitor indicates phase is correct.
If the light is not illuminated, disconnect power from the unit and swap any two power leads at the

terminal block. This should correct the phasing. The light should now illuminate when power is reapplied.

Immediately after applying power, the evaporator blower (enclosure air) should start running. Operate the air

conditioner with the compressor running ��

e (5) to ten (10) minutes. You will need to set the cooling controller

setpoint below the ambient temperature to operate the compressor.
Condenser air temperatures should be warmer than normal room temperatures within a few minutes after the

condenser impellers start.
See Sequence of Operation on page 10 for ��

ates when powered up.

HOW TO READ MODEL NUMBERS

S10

G031

1. ��

air conditioner and the approximate height (i.e. S10 = Slim Fit family

about 1000mm high (10x100).

2. This is the air conditioner’s listed capacity in Watts at rated conditions. (i.e. 15=1500W (15x100) at

35/35 C)

3. 1 = 115 Volt, 2 = 230 Volt, 4 = 400/460 Volt.

4. 5 = 50 Hz only, 6 = 50/60 Hz or 60 Hz only.
