PCP Series Start-Up Procedures

PCP Series Start-Up Procedures - GENERAL INSPECTION

START-UP PROCEDURE

GENERAL INSPECTION

1. Make sure following is in place before a Start Up:

• Pre-Start-Up Check List is completed – dehumidifier and premise are ready for a Start-Up

• Design conditions (where and what is applicable) are met. Room and pool water temperatures are brought

to design conditions to establish appropriate load; starting up dehumidifier with significantly lower load most

often would not reveal dehumidifier true performance.

• Following documents are available (familiarize yourself with following documents, including current Start-Up

Procedure, prior to Start-Up):

 Start-Up Report form – shipped from factory with the dehumidifier.

 Operation and Maintenance Manual and Touch Display Manual – shipped from factory with

the dehumidifier. Refer to these documents as needed for dehumidifier description, operation, operator

panel navigation etc.

 Contact factory to obtain copies of above mentioned documents if needed.

Completed Start-Up Report must be submitted to manufacturer within terms set in Warranty

(see Operation and Maintenance Manual) – otherwise dehumidifier warranty is void!

Take pictures of dehumidifier installation, premise etc. and submit along with Start-Up Report.

Record ALL applicable data in Start-Up Report, note and correct/address all discrepancy prior to starting up the dehumidifier.

! WARNING

2. Perform Dehumidifier Inspection – verify/perform following (where applicable):

• Dehumidifier is leveled and firmly affixed.

• External systems/components properly connected/installed and tested prior to Start-Up:

 Ductwork

 Power

 Communication lines (internet, BMS, ROP etc.)

 Control wires to external components (outdoor condenser/dry cooler, external pumps, fans, dampers,

sensors etc) – verify wiring is per wiring diagram

 Outdoor condenser/dry cooler – verify proper installation, piping, charge

! CAUTION

OAC line set MUST comply with length limits and pipe sizes shown on dehumidifier Main Label – verify/address if incorrect.

! WARNING

 Any external piping connected to the dehumidifier (heating/cooling liquids, pool water, gas etc.) –

verify correct direction and sizing

PCP Series Start-Up Procedures - GENERAL INSPECTION

Dehumidifiers with NO internally installed space heater (no space heating option included or space heater is installed

externally to the dehumidifier) would require Supply Air (SA) temperature sensor to be installed in the ductwork

downstream of space heater. SA sensor is pre-wired to the control board at the factory; sensor is provided with the

dehumidifier (close to Supply Air duct connection) in the bag with respective label.

NOTE

Some dehumidifier could be equipped with compressor isolating valves and

other manual valves that need to be open prior to dehumidifier start up!

Locate and tighten ALL hose clamps – on ALL pool water, glycol hose connections etc.

! CAUTION

 Drain – verify P-trap is installed correctly and primed

 Other systems/devices

 For dehumidifiers with water or glycol circuits (heat recovery, space heating, protocol glycol loop etc) –

verify that there is no air in the system (check automatic air vents, manual air bleeding valves etc).

 Outdoor condenser/dry cooler is charged according to the dehumidifier label (refrigerant/glycol type

and amount, if applicable).

 For dehumidifiers with external dry cooler: verify that static pressure at the compressor pump

is min 25-30 psi after dry cooler is charged (verify that air is bled out of the system – see above).

• External pumps performance (pool water, heating/cooling water, GPM etc) is per spec.

• Access to ALL dehumidifier components, doors, louvers, filter racks, access ports and covers is not restricted.

• CAUTION ! Locate and tighten ALL electrical apparatuses’ wiring terminals:

 Contactors and relays

 Distribution blocks

 Board and additional terminals

 Fuses

 Other wiring connections

• Perform dehumidifier internal and external inspection for any shipping damages, loose articles, fasteners,

wires etc – tighten/address as needed.

3. Perform Premise and Mechanical Room Inspection - verify/perform following (where applicable):

• ! No chemicals stored in same mechanical room where dehumidifier is installed.

 Having chemicals stored in same mechanical room will void warranty!

• Floor drain is present in mechanical room

• External disconnect for dehumidifier is easily accessible and clearly labeled; same is done for outdoor

condenser/dry cooler.

PCP Series Start-Up Procedures - GENERAL INSPECTION

• Before powering up a dehumidifier, verify proper voltage power supply is connected. Check at main disconnect.

• Once powered up a dehumidifier, check for proper power supply (phasing, voltage etc) at main

distribution block and at transformers’ secondary lines (24 VAC for main control one, others, if any –

as per transformer label).

• Check compressor(s) crankcase heater operation. Insure crankcase heater(s) powered.

• Check Voltage Monitor status – address respectively, if any, alarms shown:

 If Voltage monitor (VM) indicates phase reversal on three-phase power supply – power dehumidifier

down and reverse/switch any two power leads. All motors, compressors, pumps within the dehumidifier

are synchronized with Voltage Monitor – proper phasing to Voltage Monitor from main power will insure

proper rotation.

• Check Operator Panels for response (both, local and remote, ROP, if applicable) – you should see home page

on the display (refer to Touch Display manual, if needed):

 Verify that Comm status indicator (on the right side of touch display home page) is green (meaning that

communication between Touch Display and control board is OK); investigate otherwise.

! Important Notes!

• Air balancing and fans speed adjustment.

 As many other settings, Main Blower and Exhaust fans (if any) speed is set at the factory to certain, default

level. These settings normally have to be checked and adjusted (as needed – increased or reduced) during

Start Up and Air Balancing to ensure dehumidifier proper operation and correct airflow.

 Above statement applies to majority of dehumidifiers - with very few exceptions, dehumidifiers are

equipped with fans with ability to modulate/adjust their speed – fan motor could be equipped with VFD

(variable frequency drive) or fan itself could be of EC type.

 It is recommended to have Air Balancing completed prior to or, at least, at the beginning of a Start Up,

to ensure proper adjustments of refrigeration, space heating and other components (like TX valve etc) and

systems that are influenced by airflow.

Dehumidifier must be powered up at least 24 hours prior to a Start-Up for crankcase heaters to warm up compressor(s)!

Make sure it is safe to turn power on – exercise caution!

! WARNING

• Ductwork is installed in such a manner that:

 No short-cycling occurred (no closely located supply and return grills)

 No stagnant air zones

 Air is supplied onto outer windows, doors (to prevent sweating)

4. Power Up the Dehumidifier

PCP Series Start-Up Procedures - TOUCH DISPLAY BASIC NAVIGATION

START-UP PROCEDURE &

TOUCH DISPLAY BASIC NAVIGATION

Before attempting to operate the dehumidifier, familiarize yourself with Touch Display Layout and Navigation.

Refer to Touch Display Manual and current document.

! WARNING

Intro

Touch Display operator panel could be used

as local or remote operator panel.

Touch Display provides standard operator

panel’s functions (viewing sensors readings,

adjusting settings or operating dehumidifier

etc.), as well as some additional ones, like

extended Help feature, Notes feature, data

logging etc.; menus and settings structure is

very similar to web monitoring online system.

Best way to get accustomed with Touch

Display is to practice – read current document

and surf Touch Display menus, use Help

feature etc.

For more, in depth details on Touch Display layout and features, refer to Touch Display Manual.

Dehumidifier Operational Modes

The dehumidifier could operate in two distinctive control modes:

• Normal Mode (standard automatic operational mode) – dehumidifier operation is automatic and fully

controlled by software algorithm, all safeties are enabled, no person supervision is required.

• Service Mode – dehumidifier components could be engaged only manually (from Touch Display Operator

Panel), certain safeties, active during Normal Mode, are omitted during Service Mode.

By default, all dehumidifiers delivered from factory, are set to be in Service Mode (to avoid uncontrolled start of

any component without prior check or proper start-up by qualified person). Therefore, once powered, dehumidifier

should assume Service mode and Touch Display should show Service mode home page. It has distinctive

“SERVICE MODE” note displayed – see below

Touch Display home page layout

When dehumidifier is powered up, restarted or rebooted, touch display would by default show home page. Home

PCP Series Start-Up Procedures - COMPRESSOR(S)

SERVICE MODE OPERATION

COMPRESSOR(S)

Before Running Compressor(s):

• Read this entire section first before starting and running compressor(s)!

• Ensure that present load is sufficient for dehumidifier operation – RH level is at least 45%, RA temperature

is at least 78°F. Normally, running dehumidifier with load significantly lower would render Start-Up insufficient

(it would not reflect true dehumidifier operation)

• Ensure that, at least, Main blower is running; if dehumidifier is equipped with min exhaust fan and/or

OA damper – engage them also to test compressor under conditions as close to actual as possible; make

respective note in Start-Up Report - what ventilation components are running/active during Compressor(s)

Start-Up operation. Refer if needed to Ventilation section.

• Verify dehumidifier following compressor-related configurations:

 Press Advanced (top menu), then press Compressor Options

 Locate Compressor Design setting and verify it is set to Classic; adjust otherwise – select Compressor

Design and set respectively.

 Locate OACC Type setting and verify it is set to 1 Stage (if dehumidifier OAC/fluid cooler fan is EC-type

– modulating control) or Low/High (if dehumidifier fluid cooler fan is two speed fan) – verify visually if

needed); adjust otherwise. Select OACC Type and set respectively.

 Scroll through the compressor options by pressing “<” or “>” to locate setting as needed.

• Verify evaporator coil by-pass damper operation:

 Press Home (top menu) to access home page and Service (bottom) menu.

 Press Compr1 (bottom/Service menu)

 Press Bypass Open – verify damper proper operation (damper is opening).

 Once damper opens approximately half-way, press Bypass Open again - verify that damper stops and

maintains its position. Press Bypass Open again to open damper fully.

 Once damper fully opens, press Bypass Open again. Verify that damper stops and stays open.

 Press Bypass Close – verify damper proper operation (damper is closing).

 Once damper fully closes, press Bypass Close again. Verify damper stops and stays closed.

 If load (return air temperature and RH) is rather low – leave damper in closed position for testing

purposes (to maximize airflow/load across the evaporator coil). If load is sufficient - set damper into

half-open position; refer to previous steps

• Install pressure gauge set, appropriate for type of used refrigerant, and verify that gauge readings correspond

with operator panel readouts:

 Observe High Pressure and Low Pressure readouts and compare to pressure gauge set readings.

Note that low pressure transducer’s pressure reading brackets are 0-200 psi – it will display 200 psi max,

even if actual pressure is higher.

While running compressor(s), monitor load (return air temperature and RH) and adjust dehumidifier operation to maintain load

close to design data, e.g. if running dehumidifier in full AC mode brings return air temperature too low, engage space heating

or switch to full Reheat/Partial mode to compensate. Make a note of it in Start-Up Report.

NOTE

PCP Series Start-Up Procedures - COMPRESSOR(S)

Verify Compressor(s) Operation:

1. Run Compressor in full Dehumidification/Reheat Mode:

• Press Pump Down – verify button turns green and Pump Down solenoid valve energizes (check magnetic

pull on the solenoid coil stem)

• Press Reheat – verify button turns green and Reheat solenoid valve energizes (check magnetic pull on the

solenoid coil stem)

• Allow couple seconds for pressure to balance out, then press Contactor – verify button turns green,

compressor contactor engages and compressor starts.

• Allow compressor to stabilize and run for 5 - 10 min, then:

 Check and note compressor amp draw, record it in Start-Up Report

 Check/adjust superheat - aim for 15 - 25°F of superheat, adjust, if needed. After each adjustment allow

for at least 5 - 10 min of stabilization ran, then re-check superheat.

 Once superheat is adjusted and stable - record readings from touch display in Start-Up Report

(refer to Compr1 page for compressor-related readouts and Vent page for air-related readouts).

2. Run Pool Heating with Reheat (skip this step if not applicable):

• While compressor is running, engage pool heating solenoid:

 Press Heat (bottom menu),

 Press Pool Heat – verify pool heating solenoid(s) energize (check magnetic pull on the solenoid coil stem)

 If dehumidifier has two pools or staged pool heating configuration, repeat last step for second pool/

stage: press Pool 2 Heat – verify second pool/second stage pool heating solenoid(s) energize (check

magnetic pull on the solenoid coil stem)

• Verify compressor pool heating operation – observe pool water temperature readings change respectively

(Pool 1 Water In and Pool 1 Water Out for single pool, Pool 2 Water In and Pool 2 Water Out

for second pool, if applicable)

• Allow at least 3 - 5 min for stabilization and record respective data in Start-Up Report (refer to Heat page

for pool water temperatures, Compr1 page for compressor-related readouts and Vent page for air-related

readouts).

 Ensure pool water temperature differential (Pool Water Out Minus Pool Water In) is satisfactory – aim for

5 - 15°F; adjust water flow if needed.

 Press Heat (bottom menu) and dis-energize pool heating solenoid(s) by pressing Pool Heat (and, if

applicable - Pool 2 Heat) - check that there is no magnetic pull on the solenoid coil stem.

 Observe/verify pool water temperatures are equalizing.

Make a judgement call on what mode (AC, Reheat etc.) to start with, based on outdoor and indoor conditions: e.g. if indoor

(RA) temperature is relatively high, you may want to start with full AC or Partial mode (and then do full Reheat) – with high

return air temperature, compressor(s) may not sustain their operation for long period of time in full Reheat mode.

NOTE

PCP Series Start-Up Procedures - COMPRESSOR(S)

3. Run Compressor in full AC Mode:

• Verify outdoor condenser/fluid cooler operation (keep compressor running as it is while checking condenser/

cooler fan(s) operation):

 Press Compr1 (bottom menu) and engage outdoor condenser/fluid cooler fans according to their type

– EC-type fans (modulating control) or two-speed type fans (refer to previously verified OACC Type

configuration setting):

 For EC-type fans:

 Press OACC – to issue start signal for condenser/cooler fans (as well as for fluid cooler pump, if

applicable – see below)

 Press Head Press and adjust/set fan speed:

Press “+” to set fan speed to 100% (max) – verify fan engages and ramps up respectively; check

amp draw and make respective records in Start-Up Report.

Press “-” to set speed to 40-60% - verify fan slows down and run respectively.

 For two-speed type fans:

 Press OACC – verify fans engage in low speed; check fan rotation direction and amp draw;

 Press OACC again (to dis-engage low speed), then press OACC2 - verify fan(s) switch from low to high

speed; check fan rotation and amp draw; make respective records in Start-Up Report

 Press OACC2 again, then press OACC (to revert to low speed) verify respective operation.

 For fluid coolers, equipped/packaged with (integral to fluid cooler) pump - pump should engage once

OACC (OACC or OACC2 – for two-speed fans arrangement) is pressed:

 Verify pump engages; check rotation and amp draw. Make respective records (pump amp draw, static

and dynamic pressures) in Start-Up Report.

• Engage compressor AC operation. While condenser/cooler fan(s) (and pump – if applicable) and compressor

are running:

 Press A/C – verify button turns green and AC solenoid valve energizes (check magnetic pull on the solenoid

coil stem)

 Press Reheat – verify button turns white and Reheat solenoid valve dis-energizes (check that there is no

magnetic pull on the solenoid coil stem)

 Allow compressor to stabilize and run for 5 - 10 min.

Monitor compressor head pressure and adjust condenser/cooler fans speed as needed – aim at

350-480 psi. Note fans speed in Start-Up Report.

 Check and note compressor amp draw, record it in Start-Up Report.

 Verify that superheat is stable - record readings from touch display in Start-Up Report (refer to

Compr1 page for compressor-related readouts and Vent page for air-related readouts).

4. Run Pool Heating with AC – use sequence, described in step 2 (skip this step if not applicable).

PCP Series Start-Up Procedures - COMPRESSOR(S)

5. Run Compressor in partial mode – Reheat and AC:

• While condenser/cooler fan(s) (and pump – if applicable) and compressor are running:

 Press Reheat – verify button turns green and Reheat solenoid valve energizes

(check magnetic pull on the solenoid coil stem)

 Allow compressor to stabilize and run for 5 - 10 min.

 Monitor compressor head pressure and adjust condenser/cooler fans speed as needed –

aim at 350-480 psi. Note fans speed in Start-Up Report.

 Check and note compressor amp draw, record it in Start-Up Report

 Verify that superheat is stable - record readings from touch display in Start-Up Report

(refer to Compr1 page for compressor-related readouts and Vent page for air-related readouts).

6. Stop Compressor(s) once compressor(s) operation is confirmed:

• Stop compressor by pumping it down:

 Press Pump Down - verify Pump Down solenoid valve dis-energizes;

 Observe compressor pumping down and dis-engaging.

 Monitor compressor suction pressure during pump down – stop compressor manually (by pressing

Contactor) if suction pressure drops below 20 psi and compressor has not stopped yet.

• Dis-energize all compressor related components (solenoid valves, condenser/cooler fan(s)/pump etc. – refer to

previous/respective steps, if needed).

For two-compressor dehumidifiers:

• Same procedures/steps, described above, are applicable to all compressors: if dehumidifier is equipped with

(and configured respectively!) two compressors, use respective Service (bottom) menu buttons – Compr1 for

first compressor and Compr2 for second one.

• If permissible, run compressors separately and together (simultaneously).

• While running compressors together, if needed to offset separate compressor mode effect on air temperature,

run compressors in opposite modes: e.g. run one compressor in full A/C while running second compressor in

full reheat (and vice versa). This will constitute “partial mode” for two-compressor dehumidifier.

NORMAL MODE OPERATION

Finish Start-Up and Review Settings

Once dehumidifier operation in different modes is verified and respective data is recorded, stop the dehumidifier:

• Stop/dis-energize main blower and any other, if any, ventilation or space heating components – refer to

respective sections as needed.

• Review and set/correct Setpoints and Date & Time:

 Press User (top menu), then press Setpoints – review and adjust, as needed, applicable set points values;

once done - press Back. Make respective records in Start-Up Report

 It is recommended to maintain room air temperature higher than pool water temperature at least by

couple degrees, at worst – to keep them equal: having pool water temperature maintained higher than

room air temperature will cause excessive evaporating rate.

• Press Date & Time – verify date and time are correct, adjust if needed; once done – press Back.

Press System Information and record respective (MAC address etc.) info in Start-Up Report

Commission the dehumidifier and Switch to Normal Mode operation.

Once dehumidifier is ready to run automatically (all systems/components operation is verified):
